Pvc packaging film super resistance
Jun 26, 2018

Pvc packaging film is a non-crystalline material in the process of production, in the actual use of the process requires the effective addition of its stabilizers, auxiliary processing agents and lubricants, in the operation of the pvc packaging film to a certain extent It has non-flammability, high strength and weather resistance during operation, and excellent geometric stability.

Pvc packaging film can be very resistant to strong acids and reducing agents to a certain extent, and can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid when used, and it is also not suitable for contacting with aromatic hydrocarbons and chlorinated hydrocarbons. Occasions. The melting temperature of pvc packaging film is a very important process parameter.

The antibacterial mechanism of pvc packaging film, when it is operated, its current optical cfu antibacterial agent is mainly TiO2, to a certain extent, under the action of light, the surface can effectively produce a large amount of hydroxyl and oxygen, and when used With strong chemical activity, it can cause various microorganisms to organically decompose and thus have strong antibacterial properties.

When used, pvc packaging films have other antibacterial agent films as well as natural antibacterial agent films and macromolecular antibacterial agent films. Their antibacterial mechanism is through the charge on the molecular chain and the role of microorganisms, thereby inhibiting the proliferation of microorganisms and play an antibacterial role. Currently used for food packaging are mainly chitosan, sorbic acid, turmeric alcohol.
