The original film materials used in vacuum food packaging are food grade
non BPA, such as PE, PA, OPA, AL, PET, etc. These materials play different roles
in food vacuum packaging bags.
·PE film (polyethylene film) is used for heat sealing layer with high
impact strength;
·PA film (polyamide/nylon) OPA (directional polyamide): used to improve
physical strength and wear resistance;
·AL film (aluminum foil): used to increase the barrier performance and
light shielding;
·PET film (polyethylene terephthalate film) can improve mechanical strength
and hardness.
The specific food packaging production process can match different
materials according to the required content. If you have any questions about our
food vacuum packaging bags, you are welcome to consult!
