Product classification
  • Functional Composite Coated Film VPA21
  • Functional Composite Coated Film VPA21

    VPA is a material based on BOPP, with one side coated with acrylic and the other side coated with PVOH. The PVOH coating provides good barrier and printability properties. The acrylic coating is characterized by high glossiness, excellent heat sealing, and printability. When laminated with CPP or PE, VPA gains wide applicability and becomes an ideal packaging material for oxygen-sensitive foods like nuts.
