Because different products have different requirements for packaging materials, material selection should be made based on product characteristics, including whether it is easy to deteriorate, factors that cause deterioration (such as light, water or oxygen), product form, product surface hardness, storage conditions, sterilization temperature, etc. A good vacuum bag does not necessarily need to have many functions, but it depends on whether it is suitable for the product.

Anti static shielding bags can effectively isolate items from the external static field, prevent static electricity from being generated inside the bag, protect items from static electricity hazards, and also prevent electromagnetic interference. They are used for static sensitive components such as PCBs and LEDs.
