Many people usually use laminating film, such as office documents, school papers, certificates, menus, photos, etc. It can make paper stronger, waterproof and wear-resistant. But have you ever thought about how these laminating films are produced? Today we will use plain language to explain clearly - how is laminating film made?
1. What is laminating film?
Laminating film is a packaging material specially used to encapsulate paper. It usually consists of two layers of materials:
PET layer: responsible for support and transparency, which is the "bright layer" we see.
EVA glue layer: responsible for bonding, it will melt when heated, and stick the paper and film together.
When we sandwich the paper between two laminating films and put it into the laminating machine for heating and pressing, the document will be firmly sealed!
2. What is the production process of laminating film?
1. ) Raw material preparation
Mainly two materials are used:
PET plastic particles (polyester)
EVA hot melt adhesive particles
2.) Extrusion of PET film
PET raw materials are melted at high temperature and then pulled into a thin transparent film by machine.
3.) Coating of EVA adhesive layer
Then, the machine will evenly apply a layer of EVA hot melt adhesive on one side of the PET film. The thickness should be controlled in this step. Too thin will not be firm, and too thick will easily bubble.
4.) Cooling and shaping
The film coated with glue should be cooled to stabilize and shape it, so that it is not easy to deform.
5.) Slitting and cutting
According to the needs of customers, the machine will divide the large roll of film into rolls of size (such as A4, A3, 70×100mm, etc.), or directly cut it into bags one by one.
6.) Packing and delivery
The last step is to pack the box, label it, and then send it to customers all over the world.
