Complete Guide on MLP (Multi-Layer Plastic): Types, Uses, Recycling, and Market Trends
1. What is MLP (Multi-Layer Plastic)?
MLP (Multi-Layer Plastic) refers to packaging material made from two or more layers of different plastic or non-plastic films laminated together. It is primarily used in flexible packaging, especially for food, pharmaceuticals, and FMCG products.
Key Purpose:
Each layer in MLP serves a specific function such as moisture resistance, oxygen barrier, strength, sealability, or printability.
2. Common Structures in MLP
| Layer | Material | Function |
|---|---|---|
| Outer Layer | PET, BOPP | Print surface, strength |
| Middle Barrier | Aluminum foil, EVOH | Oxygen/light barrier |
| Inner Layer | LDPE, CPP | Sealability, moisture barrier |
Examples of Multi-Layer Combinations:
-
PET/Alu/LDPE
-
BOPP/PE
-
Nylon/PE/CPP
