Use of the latest technologies and production procedures and independent tool and special machine construction form the basis for the high quality of our packaging systems.

Extrusion blow moulding (EBM)

In extrusion blow moulding, a tubular preform is adapted (extruded) to the inner contours of a tool shape using pressure. A typical feature of packaging made using this technology is the welding seam at the base of the bottle.

  • Benefits: variety of design (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 PETG

Injection stretch blow moulding (ISBM), two-step process

Preforms are first produced in the injection moulding process. In the second step, known as stretch blow moulding, the preforms are heated up in the machine and stretched to the shape of the product in the tool. These bottles have a clearly distinguishable injection point at their base.

  • Benefits: rapid cycle times, high output quantities, direct link to bottling facility available
  • Products: bottles for carbonated drinks such as lemonades or mineral water as well as for household and body care products
  • Plastics used: PET, PS, PP, PE

Injection moulding (IM)

Plastic mass is injected into a tool mould under pressure and cooled.

  • Benefits: a virtually free choice of shapes and surfaces
  • Products: individual components, closures
  • Plastics used: PS, PP and PE

Injection blow moulding (IBM)

For smaller containers with high quality standards, ALPLA uses the one-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 a product mould.

  • 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
