Suzhou aluminum bags: aluminum bags, also known as moisture-proof bags, aluminum bags features: anti-static, anti-magnetic interference and moisture-proof function, there will be some light to pass through, but can also play a role in the dark for the electronics industry can be customized according to customer requirements size. Printable surface. Foil bag production process simple and complicated production process, the overall production process: aluminum ingot melting - casting - cold - intermediate annealing - cold - foil wool - roughing - in rolling - - Finishing (doublet) - cut - finished aluminum foil annealing - Compound - bag - foil bag finished - packaging. In this process, the wool from the beginning to the machined aluminum foil prime the whole process, and then the composite bag. Production of aluminum foil bag companies in order to save costs and time, usually choose direct procurement aluminum foil, then bag composite materials. Intelligent packaging materials. 4.0 With the advent of the industrial era, the development and application of intelligent packaging, food packaging will become the new trends, with a huge market potential. It is expected that future smart packaging food contain more complex, remote-readable non-visual information. Safety labels and radio frequency identification (RFID) tags are at the beginning of an electronic tag, in addition to product identification information, date of production, price, electronic tags can be used as time - temperature, leakage, or freshness indicator.
