Flexible Packaging Materials Guide
Flexible packaging materials are selected to balance strength, barrier, sealability, print quality, cost, and sustainability claims.
Flexible packaging material selection should start with product protection and filling requirements, then compare PET, PE, PP, BOPP, paper, metallized film, foil, and mono-material structures against barrier, seal, print, and recycling needs.
TL;DR
- PET often supports strength, stiffness, and print quality in laminated structures.
- PE is widely used for sealant layers and recyclable mono-material designs.
- Foil and metallized films are reviewed when light, aroma, oxygen, or moisture barrier matters.
Decision table
| Material | Common role | Buyer question |
|---|---|---|
| PET | Outer print or strength layer | Does it need high clarity or stiffness? |
| PE | Sealant or mono-material route | What seal window is required? |
| BOPP/PP | Snacks and wrappers | Is stiffness or moisture barrier needed? |
| Foil | Very high barrier | Is the added barrier necessary? |
