Easy to use transparent plastic film and packaging process

- Apr 02, 2019-

When used, the transparent plastic film mainly refers to the composite resin glue. When used, it is mainly used for the bonding of different transparent plastics. The glue is cured at room temperature, which is very convenient when used. It can be glued, glued and artificial. When the glue is completely cured, the glue is in a light transparent soft state, which is waterproof, high temperature resistant, corrosion resistant, acid and alkali resistant, and has high bonding strength.

Transparent plastic film is the most widely used in the packaging field. Plastic film can be used for food packaging, electrical product packaging, daily necessities packaging, clothing packaging and so on. They have one thing in common, that is, the plastic film should be color-printed, and as a food package, a multi-layer composite or vacuum aluminum plating process is required. Therefore, the surface of the plastic film is required to have a high free energy and a large wet tension to facilitate the firm adhesion of the printing ink, the adhesive or the aluminized layer to the plastic film.

In the process of production and high-speed packaging of plastic film, the surface of the film is required to have a certain frictional property to prevent the film from sticking or slipping; when used for packaging of electrical appliances and electronic products, the film is required to have certain antistatic properties and the like. The surface tension of a plastic film depends on the free energy of the surface of the plastic film, which in turn depends on the molecular structure of the film material itself.
