The adhesion between aluminum foil stretch film films after contact during the stretch winding process and after wrapping can make the packaged products tight without loosening. Self-adhesiveness is affected by many external factors. Such as humidity, dust and pollutants, etc. There are two main ways to obtain self-adhesive films. One is to process a film with a smooth and shiny surface; the other is to use additives that increase adhesion to produce a moistening effect on the surface of the film to improve adhesion. The stretch of aluminum foil stretch film is the ability of the film to elongate elastically after being subjected to tension. Increased longitudinal stretch will eventually thin the film and shorten its width. While longitudinal stretching is beneficial, overstretching is often undesirable. This will make the film thinner and easier to tear and increase the tension applied to the package.
