Manufacturing Process

First of all, we need raw materials which are placed on top of the barrel. Then the raw materials are heated in the process, which in turn forms liquid out of the materials. The liquid is then passed to screen changer, and bubbles are created moving the air. These bubbles are made keeping in mind the size of the liner. After the process of making bubbles, a winder is used to create rolls. Once the roll gets completed, liner cutters cut them into the desired sizes.

Material Combination

Liners are made using various materials such as LLDP, LLDPE, Filler, and Masterbatch. All these materials combine in appropriate proportions to create the perfect liner.
