Extrusions Coating Paper Lamination Plant coating machine for woven sacks, bopp,

June 7, 2014 • Mrunal Ramanuj

Extrusions Coating Paper Lamination Plant coating machine for woven sacks, bopp, 

Introduction:

High density polyethylene of HDPE woven sacks have become a versatile commodity in the
packaging industry. Introduced for the first time in India during the year 1969 it has over the years
replaced the conventional jute bags to a large exte`nt. HDPE sacks have an edge over the
conventional jute sacks in the sense that the former are light in weight, strong and attractive.
These sacks are immune to the effect of corrosion, decay, moisture, atmosphere, rats, rodents,
moths and insects. Being superior in quality and economic to the traditional jute material, these
modern sacks have gradually captured a large market for packing fertilizers, chemicals, food
stuffs, animal foods, oil cakes etc. Sacks made of HDPE are laminated with low density
polyethylene inside it. This gives protection against moisture, air and the material packed cannot
penetrate out of the sack.

Market Potential:
The primary requirement of sacking in India is for packaging of fertilizers, pesticides, chemicals,
oil seeds and good grains. The total demand at present is estimated to be around 3000 million
sacks per annum. The current sales of HDPE resins for woven sacks is around 20,000 M.T.A. or
approximately 154 million sacks. For jute sacking the sales is around 12 lakh tones per annum or
2460million sacks. This still leaves a deficit of about 400 million sacks. Therefore, HDPE sacks
rather than competing with jute sacks would on the contrary supplement the existing deficit in
sacks.

The main consumer for HDPE woven sacks in the N.E. Region at present is the Hindustan
Fertilizer Corporation Ltd., (HFC), Namrup. The HFC (Stage-I, II & III) has at present an installed
capacity of around 10,00,000 tonnes of Urea and Ammonia Sulphate per annum. On an average
the actual production works out to about 80% of the installed capacity or to about 8,00,000 tonnes
of Ammoniam Sulphate and Urea per annum. The fertilizer produce is packed in bags or sacks in
the quantity of 50 Kgs. or 0.05 tonnes per bag or sack. On this basis the total requirement of bags
or sacks is 160,00,000 Nos. per annum. Out of this requirement more than 50% (80,00,000 Nos.)
is HDPE woven sacks.

At present there is no unit manufacturing laminated HDPE woven sacks in Assam or in any part
of the N.E. Region. As a result the full requirement of laminated HDPE woven sacks are supplied
by manufacturer’s from outside the state and region. Thus 2 – 3 Nos. of laminated HDPE woven
sacks manufacturing units can come up preferably in the states of Assam and Nagaland.

Plant Capacity:
The production basis for a typical tiny unit would be as under:

Working hours/day : 8 (1 shift)
Working days in a year : 300
Annual Production capacity : 7,00,000 Nos.of laminated
HDPE woven sacks.

The unit has been assumed to operate at 70%, 80% and 90% of its installed capacity in the first,
second and third year and onwards of its operation.

Raw Material:
The main raw material required for manufacturing laminated HDPE woven sacks is HDPE of GF
– 7745 F grades. The other chemicals required are LDPE (18 LA 060 grade) and colour for
printing. LDPE is used in the laminating process or in the extraction coating process in providing
a lining of LDPE to the woven material. The colour is utilized in printing the name of the unit etc.
whose product is to be packed. The annual requirement of HDPE, LDPE and colour at 100%
capacity utilization is as follows:
HDPE : 80,000 Kg.
LDPE : 23,000 Kg.
Colour : Rs. 0.50 per Kg. HDPE requirement

This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of “legs”; while flow is more symmetrical than in annular dies, a number of weld lines are produced which weaken the film. Spiral dies remove the issue of weld lines and asymmetrical flow, but are by far the most complex.
The melt is cooled somewhat before leaving the die to yield a weak semi-solid tube. This tube’s diameter is rapidly expanded via air pressure, and the tube is drawn upwards with rollers, yielding the plastic in both the transverse and draw directions. The drawing and blowing cause the film to be thinner than the extruded tube, and also preferentially aligns the polymer molecular chains in the direction that sees the most plastic strain. If the film is drawn more than it is blown (the final tube diameter is close to the extruded diameter) the polymer molecules will be highly aligned with the draw direction, making a film that is strong in that direction, but weak in the transverse direction. A film that has significantly larger diameter than the extruded diameter will have more strength in the transverse direction, but less in the draw direction.
In the case of polyethylene and other semi-crystalline polymers, as the film cools it crystallizes at what is known as the frost line. As the film continues to cool, it is drawn through several sets of nip rollers to flatten it into lay-flat tubing, which can then be spooled or cut.

BLOWN FILM MAKING MACHINE, MONO LAYER, MULTI LAYER, ABA – INDIA

June 1, 2014 • Mrunal Ramanuj

BLOWN FILM MAKING MACHINE

<s0″>pan style=”font-size: xx-small;”>CO-EXTRUDED MULTILAYER FILM

Location of the unit:

         Location of the unit must be based on availability of infrastructural facilities such as electricity, water, transport & communication, bank etc. are also available. 900 ft² additional shed making a total plinth area of 1800 ft². to accommodate the project.

Plant & Equipment:

         Principal items of plant and equipment needed for the manufacture of co-extruded blown film is as follows: –

i) Co-extrusion film plant
ii) Corona surface treating equipment
iii) Rotogravure printing machine
iv) Co-extrusion film plant

         Co-extrusion means, combining more than one material by means of plasticizing extrusion into a unit structure in such a way that the materials will constitute distinct layers. As the co-extrusion technique is relatively a new one, special care is to be taken in the selection and procurement of the plant.

The plant essentially consists of two single screw extruders, a control panel with separate thyrister control panel for each drive motors and a heating panel for all zone heaters, film die assembly, air cooling ring and blowers, an oscillating platform which can oscillate through 300 each way, take off tower unit, trimming attachment, a two station surface winder having a roller width of 800 mm. The machine and equipment are suitable for operation on 400/440volts, 3 phases with neutral 50 cycles AC supply. All electrical heaters are single phase but the load is distributed for 3-phase supply through control cabinet. Total power load required is 85 KW.watch The Magnificent Seven 2016 film now

Corona Surface treating equipment:

         Plastics in general and polyolefin’s in particular have got a tendency to reject printing inks from their un-polarized surfaces. Hence it is necessary to polarize the surface of the film by this pre-treatment so that during printing the necessary level of adhesion is achieved.
This equipment consists of a solid-state theater, HT transformer, and special oil for above transformer, enclosed type roller assembly, an extra pair special dielectric sleeve, one extra zone extraction unit etc/

Rotogravure printing machine:

         The printing machine is specially designed in such a way that all the printing units are identical with the possibility that additional color can be attached. The machine is equipped with DC motor coupled to a thyrister converter to operate on AC mains.

Raw materials:

         Plastic raw materials such as LDPE, LLDPE, HDPE, PP, and Nylon etc. can be used for the manufacture of co-extruded film depending upon the end use of the product. Since milk pouches are generally a two-layer film (LDPE/LDPE) and the project envisages production of plastic film for milk pouches, the requirement is only LDPE. The other important raw materials required are butanol, solvent IPA and gravure printing ink.

Marketability and Scope:

         Co-extruded films find extensive use in the manufacture of pouches for packaging of various edible consumer items like milk, ghee, oils, snacks etc. It is estimated that in India about 80% of co-extruded films are being consumed for milk pouches and ghee pouches. The market for blown films is expanding and it is envisaged that more and more items would be brought under this material for packaging purposes.

Basis and Presumptions:

        The efficiency of the unit is calculated at 80% of the total production capacity.
The unit will work 25 days in a month of 3 shifts and 300 days in a year.
The time period for achieving the full envisaged capacity utilization is one year.
The labor wages are as per the prevailing rates in the market.

The melt in the extruders is conveyed forwarded by the screw rotation
The 2 extruders individually feed the 2 channels within the die
All the flow channels coverage into a single flow channel, just a little distance before the material is blown out from the annular die orifice
The rotating die ensures even distribution of the melt flow while coming out of the die orifice
The rotating die ensures even distribution of the melt flow while coming out of the die orifice
The bubble is cooled by means of air circulation arrangements
The pre-determined size of the blown film is obtained by inserting compressed air through the die.
Iris rings, flattering boards, counter rotating nip rolls draw the film upwards and flatten it into a two layer lay flat film, which is wound on the winder.
The film is also treated with corona discharge equipment and then printed in rotogravure printing machine in desired colors.

Blow extrusion of plastic film

The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line.

This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of “legs”; while flow is more symmetrical than in annular dies, a number of weld lines are produced which weaken the film. Spiral dies remove the issue of weld lines and asymmetrical flow, but are by far the most complex.

The melt is cooled somewhat before leaving the die to yield a weak semi-solid tube. This tube’s diameter is rapidly expanded via air pressure, and the tube is drawn upwards with rollers, yielding the plastic in both the transverse and draw directions. The drawing and blowing cause the film to be thinner than the extruded tube, and also preferentially aligns the polymer molecular chains in the direction that sees the most plastic strain. If the film is drawn more than it is blown (the final tube diameter is close to the extruded diameter) the polymer molecules will be highly aligned with the draw direction, making a film that is strong in that direction, but weak in the transverse direction. A film that has significantly larger diameter than the extruded diameter will have more strength in the transverse direction, but less in the draw direction.

In the case of polyethylene and other semi-crystalline polymers, as the film cools it crystallizes at what is known as the frost line. As the film continues to cool, it is drawn through several sets of nip rollers to flatten it into lay-flat tubing, which can then be spooled or cut.

Sheet/film extrusion

Sheet/film extrusion is used to extrude plastic sheets or films that are too thick to be blown. There are two types of dies used: T-shaped and coat hanger. The purpose of these dies is to reorient and guide the flow of polymer melt from a single round output from the extruder to a thin, flat planar flow. In both die types ensure constant, uniform flow across the entire cross sectional area of the die. Cooling is typically achieved by pulling through a set of cooling rolls (calender or “chill” rolls). In sheet extrusion, these rolls not only deliver the necessary cooling but also determine sheet thickness and surface texture.[6] Often co-extrusion is used to apply one or more layers on top of a base material to obtain specific properties such as UV-absorption, texture, oxygen permeation resistance, or energy reflection.

A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 inches typically) is highly important and greatly affects forming cycle times for most plastics.

High Molecular Weight High Density Polyethylene (HMW-HDPE) resin product line, which is produced

using a unique Nippon Petrochemical bimodal process. These HMW-HDPE film products are designed to

have a broad, bimodal Molecular Weight Distribution (MWD) that provides both excellent extrusion processing and physical film properties.

Formosa Plastics also produces a family of conventional HDPE film resins from

process. These HDPE film resins from this process are categorized into two types of resins: Medium Molecular Weight High Density Polyethylene (MMW-HDPE) film resins and MMW-HDPE Moisture Vapor Transmission Rate (MVTR) barrier film resins.

 Watch Full Movie Online Streaming Online and Download

HMW HDPE film resins range in density from 0.949 to 0.953 with a melt

index ranging from 0.040 to 0.15. These resins are designed with different melt index, density and/or additive packages for a variety of applications. Technical Data Sheets for these products are available at www.fpcusa.com/pe/index.html.

Films produced with HMW and MMW HDPE resins exhibit high impact and film stiffness, as well as good

tear strength and excellent tensile strength. The combination of a broad, bimodal MWD, low melt index

and high density of the Formolene® brand HDPE film resins provide an excellent balance of film performance properties for a variety of film applications.

 Watch Full Movie Online Streaming Online and Download

HDPE film resins are easily processed into very thin gauge films as low as 6 microns

(0.25 mils), as well as into heavy gauge films on the order of 96 microns (4.0 mils) or greater. The

broad MWD of Formolene® brand HDPE film resins enables them to be processed at lower melt

temperatures than competitive HMW HDPE blown film resins. This provides for better bubble stability and gauge control, as well as improved energy savings.

HDPE film resins are designed with excellent stabilization packages to protect the

integrity of the polymer from degradation, especially for applications requiring a high level of trim

recycle such as grocery bags commonly referred to as “T-Shirt” bags due to their resemblance to the undergarment.

B. BLOW-UP-RATIO (BUR) AND POLYMER ORIENTATION

To produce the best physical properties in an extruded film, the proper balance of film orientation in
the machine and transverse direction of a film must be achieved. This relationship is achieved by
adjusting the blow up ratio of the film. The blow up ratio (BUR) is the ratio of bubble diameter to the
die diameter; it indicates the amount of stretching the polymer is undergoing during the shaping of the
film.
Blow Up Ratio (BUR) = (0.637 x Lay-Flat Width) / Die Diameter
Where:
 Lay-Flat is the width of the collapsed film
 Die Diameter is the fixed diameter of a given die

The HMW-HDPE blown film lines typically have small diameter dies to achieve the relatively high BUR
ratios required to obtain optimum film properties. Other polyethylene resins, such as low density
polyethylene (LDPE) and linear low density (LLDPE) resins, normally operate at much lower BURs of 2 to
3. The typical die gaps for HDPE blown film lines are 1.0 to 1.5 mm (40 to 60 mils), which are narrower
than die gaps used for conventional LDPE and LLDPE blown film lines.

As shown in Figure 1 below, HDPE blown films lines have a very unique “High Stalk” bubble shape. The
stalk height recommended for HMW HDPE blown film lines is 7 times to 9 times the die diameter. The
characteristic high stalk bubble shape used for HMW-HDPE Blown film production results in a very high
frost line, which is the transitional phase from molten polymer to solid film. A high frost line enables
the polymer to achieve a balance of film properties by imparting more bi-axial molecular orientation in
the film in the transverse direction (TD) to match the machine direction (MD) orientation.

Figure 1
HMW HDPE AND LLDPE BLOWN FILM

Bi-axial orientation of the polymer molecules in a blown film is important to achieve a balance of the
film’s physical properties. Bi-axial orientation of HDPE blown film is much more difficult than with
either LDPE or LLDPE blown film due to the inherent differences of the polymer structures. Long side
chain molecular branching is prevalent in LDPE and to a lesser degree in LLDPE, but HDPE has very few

B. BLOW-UP-RATIO (BUR) AND POLYMER ORIENTATION

To produce the best physical properties in an extruded film, the proper balance of film orientation in
the machine and transverse direction of a film must be achieved. This relationship is achieved by
adjusting the blow up ratio of the film. The blow up ratio (BUR) is the ratio of bubble diameter to the
die diameter; it indicates the amount of stretching the polymer is undergoing during the shaping of the
film.
Blow Up Ratio (BUR) = (0.637 x Lay-Flat Width) / Die Diameter
Where:
 Lay-Flat is the width of the collapsed film
 Die Diameter is the fixed diameter of a given die

The HMW-HDPE blown film lines typically have small diameter dies to achieve the relatively high BUR
ratios required to obtain optimum film properties. Other polyethylene resins, such as low density
polyethylene (LDPE) and linear low density (LLDPE) resins, normally operate at much lower BURs of 2 to
3. The typical die gaps for HDPE blown film lines are 1.0 to 1.5 mm (40 to 60 mils), which are narrower
than die gaps used for conventional LDPE and LLDPE blown film lines.

As shown in Figure 1 below, HDPE blown films lines have a very unique “High Stalk” bubble shape. The
stalk height recommended for HMW HDPE blown film lines is 7 times to 9 times the die diameter. The
characteristic high stalk bubble shape used for HMW-HDPE Blown film production results in a very high
frost line, which is the transitional phase from molten polymer to solid film. A high frost line enables
the polymer to achieve a balance of film properties by imparting more bi-axial molecular orientation in
the film in the transverse direction (TD) to match the machine direction (MD) orientation.

Figure 1
HMW HDPE AND LLDPE BLOWN FILM

Bi-axial orientation of the polymer molecules in a blown film is important to achieve a balance of the
film’s physical properties. Bi-axial orientation of HDPE blown film is much more difficult than with
either LDPE or LLDPE blown film due to the inherent differences of the polymer structures. Long side
chain molecular branching is prevalent in LDPE and to a lesser degree in LLDPE, but HDPE has very few

A good quality machine for industrial use is one that is an all-purpose lamination or coating machine with perfect functionality.

What is adhesive lamination and how does it work?

Adhesive lamination is a finishing process where you seal off with film. It can be done with a variety of finishes sometimes with color enhancement but the main goal is to enhance durability or a desired appearance as well as comfort. The adhesive coating plant works by different techniques depending on the material. Different coating plants are able to perform hot melt adhesive bonding, an application that is not prone to effects of moisture, has high adhesion capabilities and is good on short duration outdoor use materials. This approach also allows for instant lamination, has no need for moisture and upon cooling, the material is ready for immediate use. Other machines are able to coat circular woven fabrics, producing multiple layers of lamination. Spray coating is also another lamination technique commonly used on non-woven materials. A powder spray gun is used and is able to penetrate well in to the surface of the material. Some of these machines can hold more than one spay gun, thus can be of great advantage and can meet your high industrial demands. Lamination adhesives used can be water based or solvent based. Dry adhesives are appropriate for use in fast machines. Water based ones are cheaper and can be used for lamination as well as adhesive films. Solvent based ones on the other hand are best suited for outdoor use and offer long term durability since they can confer UV protection. They also work well with both lamination and adhesive films and have high tack qualities. Spray lamination typically works best with water-based or polyurethane adhesives. The plant usually has different units, such as the lamination unit, duckling system, sandwitch unwinder and the surface unwinder.  Click here to know more about Adhesive Lamination.

How Plastic Extrusion Process Carried out with Extrusion Machinery

Plastic extrusion is the process to define new plastic products of required size and shape through extrusion machinery. You can manufacture various plastic products like piping, wire insulation, plastic sheet, adhesive tape, window frames etc. Plastic granules are melted and reform again by this machinery in required shape and design. In such process plastic granules or plastic raw materials are added to extruder cavity through hopper. In extruder the plastic material needs to be mixed with colorants or UV inhibitors to make them mix and stimulate the melting process. In plastic extruder cavity the temperature is so high that the raw materials molted and generated in liquid form. The temperature in heated extruder cavity is so high upto 400F. Sometimes the temperature goes above the normal required level which can evaporate the liquid. To stop vaporization, it requires to cool down the head to maintain required temperate in heated extruder. Cooling fans are used to cool down and maintain the temperature level. After attaining the required temperature for certain time for liquidation, the extruder screw enhances the pressure to move liquid plastic to the die through proper channel. This die is a frame where it store the liquid plastic material, came out of extruder with pressure. Now liquid plastic has been moved to the die for further looking in sealed water bath to solidify plastic material to form a plastic product. Sometimes dies are passed through special cooling rolls instead of water baths to make the die and product cool fast at required temperature.

There are various types of extrusion machineries having different extrusion process to form plastic like extrusion coating lamination plant in which Extrusion coating is used a blown or cast film process to coat an additional layer onto an existing roll stock of paper, foil or film. For example, this process can be used to improve the characteristics of paper by coating it with polyethylene to make it more resistant to water. Blown film plant is used for blow film extrusion process which is the same as a regular extrusion process up until the die. The die is an upright cylinder with a circular opening similar to a pipe die. The diameter can be a few centimeters to more than three meters across. The molten plastic is pulled upwards from the die by a pair of nip rolls high above the die. There are different types of blown film plants are used in extrusion process like mono layer blown film plant, two layer blown film plant and multilayer blown film plant.
