Superior Quality Alumium foil Packing Material
Production General Information
Characteristics of the use of aluminum foil for flexible packaging
In the process of using the aluminum foil of the substrate, the user of the flexible packaging aluminum foil is often combined with other packaging materials and then printed on the surface to further produce a high temperature resistant flexible packaging bag.
In this process, the substrate aluminum foil needs to be crimped a plurality of times at a high temperature.
For the quality requirements of aluminum foil for flexible packaging, we must control it in the production process.
In order to meet the user's requirements for the mechanical properties and surface degreasing effect of aluminum foil products (no deformation at high temperature, no cracking, surface brushing test reaches "A" grade), first select the appropriate alloy composition, and choose when annealing the finished product. Suitable heating temperature and holding time (generally 250 ° C -258 ° C, holding 30-50 hours).
