What Is A High Resistance Diaphragm

High barrier film is a multi-layer structure film made by extruding materials with strong gas barrier properties and polyolefins with strong thermal and moisture barrier properties simultaneously.

Coating high barrier film:
PVA coated high barrier film is made by coating PVA with nano inorganic substances onto polyethylene film and then printing and compounding it. It solves the technical bottleneck of poor barrier performance of three-layer polyethylene co extruded packaging film without significantly increasing the cost. PVA coated high barrier milk film has been fully introduced to the market. Its oxygen barrier rate is less than 2cm3/(m2 · 24h · 0.1MPa), and its barrier performance is not only significantly better than EVOH five layer co extruded film, but also significantly reduces packaging costs. This not only ensures all quality requirements for sterile packaging of the packaged material, but also greatly reduces the cost of sterile packaging for food processing enterprises, solves the technical bottleneck of poor barrier performance of three-layer polyethylene co extruded packaging film, and can be used for packaging beverages, fruit juice, milk, soy sauce vinegar, etc.
