PVC double-sided packaging film

PVC double-sided packaging film is a convenient and versatile packaging material, widely used in the outer packaging of various products such as food, beverages, indoor doors, household appliances, daily chemical products, daily necessities, cultural and educational supplies, sports equipment, and so on. During the packaging process, the shrinkage rate is stable and balanced. After the packaging is completed, the corners are soft, resilient, resistant to low temperatures, and will not harden, protecting the packaged items. Suitable for the requirements of most automatic and semi-automatic packaging machinery, it is an economical and bi-directional shrink heat shrink film product.

PVC double-sided packaging film is also known as polyvinyl chloride heat shrink film. Colorless (original color) products have transparency, and can also be produced into various colors of PVC heat shrinkable tubes by adding color masterbatch, which can protect and beautify the product. The PVC film produced by our company has a high thermal shrinkage rate and is very suitable for packaging irregular and irregular products.

Physical and mechanical properties of the product:

(1) Product appearance: Smooth surface, uniform thickness, no obvious spots, no oil stains, impurities, or creases.

(2) Specific gravity: 1.36.

(3) Thermal shrinkage rate: tested at 100 ℃, the transverse shrinkage rate is 48 ± 3%, and the longitudinal shrinkage rate is 12 ± 3%, which can tightly adhere to the product. It can be shrunk with a heat shrink machine, a hair dryer, or boiled water.

(4) Flexibility performance: After packaging shrinkage, it can be dropped from a height of 1 meter in different directions vertically and horizontally onto a cement floor three times without cracking.

(5) Color: After packaging shrinkage, it should be stored at 30 ℃ without any color changes such as fading or discoloration.

(6) Stretching degree: less than 2%.

(7) Water absorption rate ≤ 0.5%.

(8) Natural shrinkage rate: Natural shrinkage ≤ 0.5% when stored in an environment at 30 ℃.

(9) The resistance coefficient is ≥ 1 × 1015 Ω/cm3 (relative humidity at room temperature ≤ 65%).
