Plastics and their properties and applications in packaging

Material

Properties

Examples of applications

Bioplastics

Based on renewable resources (starch): corn, potato, cereals etc. and oil-based plastics, depending on the case

Depending on the material:
- Transparent or opaque
- Rigid or flexible

- Tear and crease resistance

- Good stretching
- Touch effect

 

- Trays
- Boxes

- Chucks

- Films

- Bags
- Waste bags
- Disposable tableware

 

Complexes

Combination of materials based on PE, PP, PVC, PET, EVOH, PVDC, aluminium, paper or board

 

- Matching properties of different materials used: barrier, printability, sealing, etc.
- Combination of almost all materials possible
- Targeting of required properties (odour barrier, opacity, perforation resistance, etc.)
