ESD bags also known as anti electro static bags, ESD safe bags or static shielding bags are the primary method of packaging ICs, circuit boards and delicate electronic products to protect them against static electricity.
Multilayer Layers Coextruded blown film is replacing the conventional packing materials like paper, aluminum foil, tin, glass etc. These films are considered for packing purpose because of specific requirement of shelf life and protection to product. With its excellent resistance to puncturing, heat sealability, gas barrier, high mechanical property high bursting strength etc. properties these films are having very good scope for packaging.Co-extruded vacuum bags by using 5 layer, 7 layer, 9 layer and 11 layer mixtures of polyethylene, EVOH and nylon resins which offer long lasting robustness and reliability. These vacuum bags have unique stretching capability, which enables them to store any food item. Co-extruded vacuum bags have good collision resistance and less speed for oxygen transfer. For co-extruded bags high graphic printing is not suitable, it only holds surface printing but on the surface of film the print does not shine much. These vacuum pouches are highly flexible, efficient and functional, and are compatible with all kinds of vacuum machines.Multi layer co extruded film could avoid contamination of ink volatile during lamination, more safety & environment friendly. The enforcement flexibility of vacuum bag, pin hole resistance, extend shelf life through co extrusion process could reduce bursting and leakage problems.
