High levels of transparency and puncture resistance are the most important features of ALLVAC’s flexible, coextruded PA/PP/PA/PE medium barrier composite films. This type of film is composed of polyamide, polyethylene and, additionally, polypropylene (PP). It is a thermoplastic, semi-crystalline and non-polar plastic with similar properties to polyethylene, but is harder and more heat-resistant. Films containing this additive are ideal for extreme thermoforming applications and offer reliable product protection. They are primarily used for packaging smoked or air-dried hams such as Black Forest ham, Prosciutto Crudo, Parma ham, Jamon Iberico or Serrano ham but also for classic applications such as packaging spareribs or bones. Even products that are deep-frozen retain their appetising appearance at the point of sale while the packaging is a reliable protection.
