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.
| 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
MLP is widely used in industries such as:
Snack packs (chips, biscuits)
Frozen foods
Coffee & tea pouches
Ready-to-eat meal packaging
Blister packs
Sachets for powders and syrups
Shampoo sachets
Detergent packets
Cosmetic tubes
Lubricant pouches
Fertilizer & pesticide packaging
Excellent barrier properties
Lightweight yet durable
Extended shelf life of contents
Customizable for branding and print
Low cost for mass packaging
Difficult to recycle due to the mixed-material layers
Not compatible with standard single-plastic recycling systems
Contributes to plastic pollution and landfill load
Requires advanced recycling methods like pyrolysis or co-processing
| Method | Description |
|---|---|
| Co-processing | Used as fuel in cement kilns |
| Pyrolysis | Converts MLP waste to fuel or oil |
| Delamination | Mechanical/chemical separation of layers |
| Compression Molding | Converts waste into sheets or boards |
Products from Recycled MLP:
Plastic boards and tiles
Outdoor furniture
Roofing sheets
Road construction material (as binder)
| Parameter | Details |
|---|---|
| India’s Annual MLP Waste | ~3 million tons |
| Global Concern | Major contributor to ocean plastic |
| Recycling Rate | Very low (<10%) |
| Government Push | EPR (Extended Producer Responsibility) |
Recent Trends:
Rise in MLP collection drives by brands
Innovation in MLP-compatible recycling tech
Use in circular economy models
