Advantages of plastic are corrosion resistant and chemically inert. They have low thermal expansion of co-efficient and possess good thermal and electrical insulating property. Advantages of plastic is very good water resistant and possess good adhesiveness. Plastic is strong, good and cheap to produce.
1.Low cost for high production rate
4.High strength to weigh ratio
5.Good chemical resistant
6.No post processing is required after injection Molding......
It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight. Many studies comparing plastic versus paper for shopping bags show that plastic bags have less net environmental effect than paper bags, requiring less energy to produce, transport and recycle.
