There is a close relationship between the oxygen transmission rate and its food shelf life, so a good stretch film has a certain protection and prolongation effect on the protection of food

The physical and mechanical properties mainly stipulate the technical indicators of tensile force, elongation at break, viscosity, permanent deformation, elastic recovery tension retention, and puncture resistance, and expound the detection method. The standard stipulates the inspection rules in detail and has undergone repeated deliberations on the inspection classification, sampling plan, and judgment rules, so as to strive for strong representativeness and strong operability. The rules for factory inspection and type inspection are determined.

The standard stipulates the marking, packaging, transportation, storage and other methods of the product, especially the storage method and the shelf life are regulated first.

Because the aging of stretch film is the direct cause of life loss, when we encounter problems, we must deal with them in time without delay.
