We bought a new vacuum pump

A new vacuuming machine has been purchased for the vacuum test of bags. Vacuum bags, also known as close-fitting moisture-proof bags, aluminum foil bags and aluminum-plastic composite bags, are generally made of NY/PE or PET/NY/ PE. Among them, PET- good printing effect, NY- low oxygen permeability, AL- strong barrier, PE- Heat sealing layer. This product has good anti-static, oxygen isolation, shielding, moisture-proof, light shading function and excellent heat sealing.
