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.pantai kuta bali

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
