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, 


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

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

What is Blown Film Extrusion?

  • Blown Film Extrusion is one of the most common polymer conversion processes in the world
  • Film is made by extruding molten plastic through a circular die, forming an inflated tubular bubble that moves through a cage as it cools, that is then collapsed and formed into rolls
  • The typical film blowing process consists of a series of stages, including extrusion, blowing, collapsing, and winding

Polyethylene Film Processing Guide





high density polyethylene (HDPE) resins for

mainly blown film applications. The workhorse of Formosa Plastic’s HDPE film resins is the Formolene®

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.


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


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.


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.

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
Blow Up Ratio (BUR) = (0.637 x Lay-Flat Width) / Die Diameter
 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

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

Enhance Your Manufacturing Potential and Maximize Returns with the Plastic Extruder

November 1, 2013 • Mrunal Ramanuj

Production of plastics can be done through various processes .These include blown film process, extrusion blow techniques, injection molding ,stretch blow molding, rotational molding, machining and even thermo molding. Each of these modes of manufacturing has specific advantages in relation to the desired final products.

The plastic Extrusion process

The extrusion process involves use of a thermoplastic material that is in form of pellets, granules or even powder. Raw material is heated to form a uniform molten liquid in the extruder machine. The molten liquid is forced under pressure through a die opening to create the shape of the final product.

The resulting form is pulled from the die from the exit side carefully. The resulting product is sliced into specific lengths or wound depending on the specifications. Further processing can be done to customer requirements such as threading.

The most important characteristic of the extrusion process is that the products have a uniform cross section as opposed to injection molding, which gives products with varying cross sections.

The machinery involved in the extrusion includes pellets handling equipment for conveying the raw materials to the extruder, heating system, the molding block and the extrusion assembly.

Additives such as lubricants, stabilizers, colorants and anti oxidants can be added to the raw materials to improve their physical qualities such as color, strength and even the flexibility of the product.

The main purpose of the extruder is to develop a uniformly melted material at a constant rate and pressure and maintain constant temperature. These specifications are crucial because slight variations affect the quality of the product.

Products Made through the plastic extrusion process

  • Tubing and hollow pipes; PVC pipes and tubes have a uniform cross section and they are made using the extruder machine. The size of the extruder is dependent on the size of the product.
  • Solid Rods; these are further used as raw materials for production of other plastic products. They may be square, round, or even hexagonal blocks as long as the cross section is uniform.
  • Sheet formations: These are products such as machine guards and windows glazing which are resistant to impact.
  • Manufacture of Shapes with extended uniform cross section such as vehicle wipers and house gutters .
  • Production of electrical cable insulation also utilizes the extrusion process.

Contribution of the Plastic Extruder in the Manufacturing Industry

The extrusion process is one of the most important processes of plastic manufacture. The process is fast and easy to customize to product specifications. It is also easy to implement and with proper calibration, it produces very high quality components.


The plastic extruder is a machine used in manufacture of uniform cross section plastics such as pipes, tubing, sheet plastics and even plastic rods. The extruder must deliver a uniform molten resin at a constant temperature for high quality product.

The extrusion process involves filling molten plastic into a mould and allowing it to solidify. The product is then drawn from the mold to give long uniform cross section product.

This process is one of the most important processes in plastics manufacture with wide spread usage and produces high quality products.

How Plastic Extrusion Process Carried out with Extrusion Machinery

December 28, 2011 • Mrunal Ramanuj

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.

The Roll of Plastic Extrusion Machineries in Extrusion Process

December 28, 2011 • Mrunal Ramanuj

The Roll of Plastic Extrusion Machineries in Extrusion Process
Plastic extrusion process is well defined from ancient period. The concept is to generate the required plastic product from raw plastic material. The process seem easy is not as easy. It requires extrusion machinery to melt plastic granules or raw materials at certain high temperature like 200 centigrade along with the soluble materials to melt down the raw granules. The granules are heated and molt down in the heating extruder cavity which is operating and controlled at certain heating temperature. On completing the melting process, the liquid plastic is forced to the die by screw pressure method. This melted plastic is cooled in die to define particle shape for the product. There are various extrusion machineries applied in industries like blown film plant, extrusion coating lamination plant, raffia tape stretching plant, PP box strapping plant, PET box strapping plant, PP/ HDPE monofilament plant, sutli plant, reprocess plant, PP-TQ blown film plant etc. Each machinery contains plastic extruder for extrusion process.
