The treinta-y-tres 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:treinta-y-tres 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 treinta-y-tres 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 treinta-y-tres moisture-proof, heat-insulating, and light-proof functions. Some products will use aluminum-plated materials to enhance reflectivity and treinta-y-tres durability.
