Raw materials used
HDPE (High Density Polyethylene), LDPE (Low Density Polyethylene), PP (Polypropylene), COC (Cyclo-Olefin-Copolymer), COP (Cyclo-Olefin-Polymer), PET (Polyethylenterephthalat), TPU (Thermoplastic Polyurethane), PC (Polycarbonate), PS (Polystyrene), SAN (Styrol-Acrylonitrile-Copolymers) and Barex (Acrylonitrile). Many other materials are also possible.
Use
Containers such as bottles, crucibles, pots or flacons with small or large openings. For packaging liquid and powdery products and tablets. Also for sealed storage of dry contents and single-portion packages.
The content volumes are variable, from approx. 1 millilitre (for eye drops, ear drops etc.) to about 2000 millilitres (e.g. for the food industry).
Pharmaceutical products, cosmetic products, body care products, food, food supplements, high-value consumer goods and more.
Advantages
- Low tolerances
- Precision opening area with outstanding tightness in comparison to the extrusion blowing procedure, screw closures with injection moulding quality
- Pressure-resistant
- Seamless in the neck and base area
- The wall thickness is more uniform than with the extrusion blow moulding procedure
- High surface quality
- Low wastage, waste-free manufacturing, therefore environmentally friendly
- More design options than with injection moulding
- Wide range of raw materials can be used, particularly also transparent polymers
- Large number of cavities possible, therefore suitable for mass production
- The mould shape is more reliable than with the extrusion blow moulding procedure
Disadvantages
- No container handles possible
- Limited hollow container volume (approx. 1000 to maximum of. 2000 ml)
