LDPE/LLDPE Pouch Films
Plastic, today, is being increasingly utilized in almost every industry and activity. Its use has become indispensable due mainly to certain inherent properties like light weight, corrosion of chemical resistance etc. Plastic in many areas is not only a strong substitute but superior as well. To cite an example packaging industry now depends on plastic for packaging of milk, edible oils, snacks etc. and co-extruded films are predominantly used in this direction. It has been observed that in the domestic and international market, more particularly for developing countries such water pouches do not have any protection from direct sunlight exposure. Therefore, such water pouches produces offensive odour in the water within one or two days. Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins. LLDPE has penetrated almost all traditional markets for polyethylene; it is used for plastic bags and sheets (where it allows using lower thickness than comparable LDPE), plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables, geo membranes and mainly flexible tubing. The packaging industry is estimated at Rs 150 bn and is growing at 14-15% annually. This growth, according to industry watchers, is expected to double in the next two years. It is estimated that more than 80% of packaging in India constitutes rigid packaging, the rest being flexible.
