Why Choose Orbi Packaging's Collation Shrink Film?
Co-Extrusion or Mono Layer Shrink Film?
We offer both co-extrusion and mono layer shrink film to suit a wide range of packaging applications.
Mono Layer Film
A mono layer film is made from a single layer of plastic resin, typically extruded from one type of polymer (for example, LDPE or LLDPE).
- Composition: One uniform material throughout.
- Performance: Basic mechanical and barrier properties — strength, clarity, or flexibility depend solely on the chosen polymer.
- Cost: Generally cheaper to produce.
- Use: Suitable for simple applications where high performance or barrier protection isn’t required.
Co-Extrusion Film
A co-extruded film is made from multiple layers of different polymers, extruded together in a single process. Each layer serves a specific function — such as strength, sealability, clarity, or barrier protection.
- Composition: Typically 3 to 11 layers of different materials.
- Performance: Combines the best properties of several polymers — one layer for strength, one for clarity or gloss, one for barrier protection (moisture, oxygen, UV), one for printability or sealability.
- Cost: Slightly higher, but more efficient and durable, often reducing material usage overall.
- Use: Ideal for demanding packaging applications where performance, appearance, or sustainability matter.
- Example: Collation shrink film for bottled water packs, form-fill-seal films, or food packaging films.
| Feature | Mono Layer | Co-Extrusion |
|---|---|---|
| Structure | Single layer | Multiple layers (3–11 typical) |
| Customisation | Limited — mainly thickness, width, or basic additives |
Multiple layers can be tailored independently:
|
| Strength & Performance | Basic | Superior |
| Barrier Properties | Low | High (moisture, gas or UV barrier) |
| Cost | Lower | Higher initial, but better long-term value |
| Application | Simple wrapping | Advanced or high-speed packaging lines |
