Compounding goes through several processes: compounding, printing, bag making. What are the components of the price? Vacuum packaging bags, tea packaging bags, how many materials, thickness, and types of viscose (except co-extrusion) affect price factors. For example, aluminum foil vacuum composite bags that are resistant to high temperature 121 degrees sterilization, the material needs to be resistant to high temperature, and viscose also has high temperature resistance. The price is more expensive than ordinary composite bags. The larger the specification, the more materials are used, the more materials are used for startup loss, and the higher the price is.
