Material VF4N
This lamination of film, aluminum foil and polyethylene has a wide range of uses where vacuum processing or a highly puncture resistant barrier film is needed. It is ideal for packaging of items susceptible to corrosion, and in food packaging, where very low oxygen levels are required. The outer layer of nylon provides a superior oxygen barrier and makes this material ideal for vacuum sealing packaging.
