VCI film manufacturers teach you to choose VCI anti-rust film

In recent years, many metals or electronic equipment manufacturers have chosen to cooperate with VCI anti-corrosion film manufacturers and purchase a large amount of VCI anti-corrosion film, anti-corrosion bags, and even anti-corrosion paper.

Then how to choose a high-quality anti-corrosion film with guaranteed quality.

Good quality VCI vapor phase anti-rust film, good quality from the packaging, the appearance of the anti-rust film is soft, and the VCI film you choose has good flexibility, it can almost be judged when the color changes or becomes brittle after standing for a period of time In order to be inferior VCI vapor phase anti-rust film.

Good quality VCI anti-corrosion film in the production process should be uniform in thickness, light transmittance is slightly lower than ordinary polyethylene film, the overall feel is smooth, grainy, and excellent tensile properties.

Since the inferior VCI vapor phase anti-corrosion film is beneficial to the management of production costs, most of the polyethylene particles are recycled and manufactured using cheap and inferior VCI raw materials.

Therefore, there are many unfavorable factors on the surface of the VCI vapor phase anti-rust film, such as many crystallization points, many wrinkles, obvious water lines, uneven film thickness, wrinkles, and extremely poor transparency.

Choosing a poor quality VCI vapor rust preventive film that has no stretchability and greatly reduced heat-seal performance, etc., has no effect on the rust protection of metals, but the poisonous gas contained in it contaminates the metal.
