Extrusion blow moulding (EBM)
In extrusion blow moulding, the material is extruded into a parison. The parison is then clamped into a mould and blown into its final shape. A typical feature of packaging made using this technology is the welding seam at the base of the bottle.
- Benefits: variety of designs (round, angular, oval, with handle), flexible production output.
- Products: bottles and packaging for cosmetics, household products, drinks, and food as well as oils and lubricants.
- Plastics used: HDPE, LDPE, PP, and extrudable PET.

Injection Stretch Blow Moulding (ISBM) 2-step
Preforms are first produced in the injection-moulding process. In an independent, second step, known as stretch blow moulding, the preforms are reheated and stretch-blown to the final shape in the blow cavity. These bottles have a clearly distinguishable injection point at their base.
- Benefits: rapid cycle times, high output quantities, in-house and in-line solutions possible.
- Products: bottles for beverages, home care, and personal care products.
- Plastics used: PET, PS, PP, PE.

Injection Stretch Blow Moulding (ISBM) 1-step
Preforms are first produced in the injection-moulding process. Directly afterward, the tempered and still soft preform is stretched and blown to the final shape in the blow cavity. In 1-step moulding, these two steps are carried out in one machine. These bottles have a clearly distinguishable injection point at their base.
- Benefits: premium surface quality, no transfer ring necessary.
- Products: high-end cosmetics, wide-mouth jars, pharmaceutical packaging.
- Plastics used: PET, PE, PP, PS, etc.

Injection Moulding (IM)
Injection moulding is the high-pressure injection of the raw material into a mould, which shapes the polymer into the desired form.
- Benefits: a virtually open choice of shapes and surfaces.
- Products: individual, technical components and closures.
- Plastics used: PP, PE, PS, etc.

Injection Blow Moulding (IBM)
For smaller containers with high-quality standards, ALPLA uses the 1-step injection blow moulding process at selected locations. In this process, a preform is first produced, which is then immediately passed to a moulding tool and blown into the final shape.
- Benefits: high dimensional accuracy, low weight fluctuation, good finish quality.
- Products: jars for cosmetic products, roll-on deodorants, containers for pharmaceutical products.
- Plastics used: PE, PP, PET.
