1. Building material grade packaging bags for food
Some heavy-duty packaging bags originally used for building materials and industry are reused as food packaging because their materials meet food contact standards. The main features include:
High-strength materials: such as PP Woven Bags or Kraft Paper Bags, which can bear more than 5kg and are suitable for large-volume foods (such as pet food and charcoal blocks).
Functional design: Valve Bag is convenient for filling powdered foods; Square Bottom enhances stability.
2. Structural design of food-specific packaging bags Composite material bags designed for food characteristics enhance support and functionality:
Three-dimensional structure bags: such as Shaped food bags and Standing Zipper Bags, which enhance self-reliance through bottom folds or side seals, making it easy to display liquid/granular foods.
Reinforced composite material: Aluminum foil or composite laminated material is used, which is moisture-proof, light-proof and mechanically strong, suitable for coffee, snacks, etc.
