What Do I Need To Pay Attention To When Purchasing Stretch Film?

Stretch film has become an indispensable packaging material in our life and work, stretch film is mainly stable, cover and protect the product, good transparency, light transmittance of 80%, can display the product, can invisibly promote the product, but also reduce the distribution error in the logistics link. Nowadays, there are a large number of stretch films that are easy to pull off in the wholesale market, so what should I pay attention to when wholesale stretch film?
First: look at the appearance of stretch film

The surface of the stretch film should be smooth and smooth, no wrinkles or only a small number of active folds, no obvious unevenness, black spots, impurities, crystal points and stiff blocks, no stripes, spots, violent tendons and other drawbacks, no bubbles, pinholes and ruptures, the aluminized layer of the aluminized film should be uniform, and no obvious bright strips, yin and yang surfaces and other phenomena are not allowed. In addition, the surface of the film is required to be clean and free of dust, oil, etc.

Second: look at the size and specifications of the stretch film

Size and specification are the basic specifications of users when ordering. The width deviation, thickness deviation, core length deviation, core inner diameter deviation, and film roll quality deviation items are suitable for China's actual conditions. Moreover, it should be uniform in thickness and thickness, with small deviations in horizontal and longitudinal thickness, and the deviation distribution is relatively uniform.

Third: look at transparency and gloss

For transparent stretch film, its light transmittance requirements are high, generally should reach more than 92%. For opaque stretch films, such as white films, they are required to have high whiteness and good opacity. In addition, the stretch film should also have good gloss.

Fourth: look at the manufacturer's environment and service

The environment and material of the stretch film are very important, if the environment is not good, there are many impurities in the dust, then the transparency of the stretch film produced is not high, and the material is also high. See whether the stretch film product has passed the SGS test and whether it meets the (ROHS) international environmental protection standards.
