The storage of stretch film requires attention to multiple aspects. Firstly, regarding the storage environment, stretch film should be stored in a dry and well ventilated warehouse to avoid humid conditions. Moisture can cause a decrease in the self-adhesive properties of stretch film, and even lead to mold on the surface of the film, affecting its effectiveness. The temperature in the warehouse should also be maintained appropriately. For PE and PVC stretch films, it is generally recommended to store them at a temperature between 5-35 ℃. Temperatures that are too high or too low can have adverse effects on the performance of the stretch film. High temperature will make the stretched film soft and adhesive, while low temperature will make it hard and brittle.

Secondly, the stretch film should be protected from direct sunlight. The ultraviolet rays in sunlight can accelerate the aging of stretch films, making them brittle and reducing their strength. Therefore, when storing in the warehouse, shading cloth should be used or stretch film should be placed in a cool place to prevent UV exposure. If temporary storage is required outdoors, the stretch film must be completely covered with waterproof and sun resistant tarpaulin to prevent erosion from sunlight and rain.

The stacking method of stretch film is also crucial. The stretch film should be neatly stacked in rolls to avoid stacking too high. Generally, the stacking height should not exceed 2 meters to prevent deformation and adhesion of the bottom stretch film due to compression. When stacking, keep the core of the roll perpendicular to the ground to avoid stretching, tilting or collapsing the film roll. Meanwhile, stretch films of different specifications and materials should be stored separately and labeled for easy access and management. In addition, during the storage of stretch film, it should be kept away from sources of fire and heat to prevent fires or melting and damage to the stretch film due to high temperatures. Regularly inspect the stored stretch film for damage, aging, and other conditions to ensure that the stretch film performs well during use.
