Basic Parameters For Using Stretch Film Machine

1. The stretching temperature is generally controlled between 85-90 ℃, but the temperature can be adjusted appropriately according to different equipment and stretching effects.
2. It is required to use arc-shaped molds for stretching as much as possible to ensure that the four corners have a certain thickness after stretching, reduce the amount of air leakage caused by damage after product packaging, and ensure the shelf life of internal products.
3. The heat sealing temperature is generally controlled between 125-130 ℃. While ensuring the heat sealing fastness, it is required to keep the heat sealing temperature as low as possible to avoid stretching deformation, shrinkage cracking, sticking, and leakage during the heat sealing process.
