Abstract:
Thermo-plastic materials like High Density Polythene (HDPE), Poly-Vinyl Chloride (PVC) can be
blow moulded into containers of different sizes and shapes. Some of the common items that are
produced include buckets, mugs and jerry cans. Buckets, cans and mugs are produced from PVC
and that of Jerry cans from HDPE. Their light weight, flexibility, corrosion and chemical resistance
have made these plastic products popular for storage and handling of water, petrol, diesel etc.

cows and buffaloes, which has now becomes costly affairs. In recent years, plastic combs are
being used increasingly it being convenient to handle and economic. Plastic combs are being
