Product Application

Food Packaging – Nuts & Ham

  • Nuts (almonds, peanuts, cashews):​ High oil content requires oil barrier + oxygen barrier to prevent rancidity.
  • Ham and processed meats:​ Needs oxygen barrier to maintain color and freshness, plus moisture barrier to prevent drying.

Food Packaging – Spicy Strips (Latiao) & Bread

  • Spicy strips (latiao):​ Oil-rich, strongly flavored – PVDC’s oil resistance and aroma retention are essential.
  • Bread and baked goods:​ Moisture barrier keeps bread soft; gas barrier extends mold-free shelf life.

Household Products – Mosquito Coil Wraps

  • Mosquito coils contain volatile active ingredients that must be retained.
  • PVDC coating prevents fragrance/active compound loss and blocks external moisture.
  • Transparent film allows visual inspection of the coil.
