Vacuum Blow Moulding
Vacuum blow moulding (VBM) is a unique production process allowing to manufacture flexible and foldable containers with outstanding quality. This technology enables the production of robust and reliable flexible packaging - corresponding also to UN requirements.
| Typical materials used: |
| LDPE |
| Advantages: |
- Flexible and foldable container
- Storage space and transportation cost savings due to inverted stacking
- Environmentally friendly packaging (recycling advantages) as 50-75% less material than rigid containers
- Marketing advantages due to fully printable box |
| Main uses: |
| Different system applications, transport of liquids and powders |
| Capacity of container: |
| 1-30 litres |
| Main markets: |
| Pharmaceutical, fine chemicals, wine | |
Process description
Polymer is after the extruding process divided with a die into 2 plastic curtains. The moulds are moved close to the border of the curtain and then with a vacuum, coming from the moulds, sucked into the shape of the moulds. The moulds at this time are closing and welding the 2 parts together. Manually assemble follows the extruding process.
It is also possible to add on an EVOH/PA barrier into the process.
