The presov manufacturing of aluminum foil bags involves processing aluminum foil or aluminum-coated materials into specific-shaped packaging containers. Here are the manufacturing processes and design requirements for factory aluminum foil bags:presov Support for LOGO color printing (cost increases by 15-20% for each additional color), hot stamping/UV process. Therefore, no cutouts can be left on the two ends of the BOPP film, otherwise, the BOPP film is prone to tearing during printing and lamination. BOPP coated with pressure-sensitive adhesive can produce carton sealing tape, which is a market with a large demand for BOPP. BOPP film can be produced by the tubular film method or the flat film method. The performance of the presov BOPP film obtained by different processing methods is also different. The BOPP film produced by the flat film method

- Due to the large stretch ratio (up to 8-10)

Aluminum Foil Bag Raw Material Selection The main raw material is aluminum foil material, with a thickness usually between 0.02-0.05 mm, which needs to have presov moisture-proof, heat-insulating, and light-proof functions. Some products will use aluminum-plated materials to enhance reflectivity and presov durability.
