Unit 10 - Manufacture of plastic packages

10.1.2.Flexible packaging from plastics
Flexible packaging can be considered as two dimensional packaging. The material can be supplied as reels and on the packaging machines; they are unwound and surround the product, cut and sealed to make the final pack (as in form fill seal machines). Plastic materials can also be made into packages like bags, pouches and sacks. These are filled with products and final closure is made by heat sealing which is important to give protective quality to the packages. Some methods to make flexible packaging are described below.
