PVA coated high barrier film
PVA coated high barrier film is a multi-layer structure film composed of materials with strong gas barrier properties and polyolefins with strong thermal stitching and water barrier properties. PVA coated high barrier film is made by coating nano layered silicate modified PVA onto polyethylene film, printing, and composite, with an oxygen resistance rate of less than 2cm3/(m2 · 24h · 0.1MPa).
Its barrier performance is not only significantly superior to EVOH five layer co extruded film, but also significantly reduces packaging costs. This not only ensures all quality requirements for aseptic packaging for the packaged goods, but also significantly reduces the cost of aseptic packaging for food processing enterprises, solving the technical bottleneck of poor barrier performance of three-layer polyethylene co extruded packaging film. It can be used for packaging beverages, fruit juice, milk, soy sauce vinegar, etc.
