Process of Manufacturing of Plastic Bags
Various specialized attachments are used, but the overall process remains almost the same. The blending of materials, extrusion, printing, and finishing are vital steps. Below is a simple description of the overall process of manufacturing:
1. Blending of material – The polyethylene/polypropylene resin is mixed with some important additives. They are:
•EPI – It is included to make the bag degradable.
•Masterbatch for making the colored film. It may be black, yellow, white, blue, or red.
•UVI, also known as an ultraviolet inhibitor is used for protecting the bag from UV radiation.
•Anti-static is used to prevent the sticking of plastic layers with each other. It enables easy opening of bags.
2. Extrusion – Once the process of blending is complete, the mixture is extruded through an annular die. The airstream will help in blowing the bubble up followed by cooling down the plastic to make various types of plastic films.
This important step will affect the strength, thickness, consistency, and transparency of the film.
3. Printing - Once films are made in roll form, further processing of printing if required can take place on the printing machine. Based on printing designs along with several colors, the exporter in India and the USA provides prints to plastic bags. It may be either flexo or gravure.
4. Bag Making: Giving a finishing touch – Now comes the touch of providing a finishing touch. Cutting sealing and folding are three important steps involved. The method may vary on the type of bag.
These are some important steps used for the manufacturing of plastic bags.
