The first food-grade PET sheet extrusion line on the New Zealand market

The strategic partnership between Amut and Erema helps to accelerate the transition to a greener world. In the summer of 2021, Erema and Amut completed the installation and commissioning of Alto Packaging's first food-grade PET sheet extrusion line in the New Zealand market. At the Alto plastic packaging plant in Albany, the plant now cleans 100% of the consumer peeling products into 100% food contact grade single-layer thermoformed sheets. In New Zealand, this milestone represents the first system installed for this particular application.

Plastic packaging company Alto, a division of the Pact Group, invested in this new food-grade PET sheet extrusion line as part of the Pact Group’s vision to lead the circular economy through packaging in Australia and New Zealand.

Due to the direct combination of the Vacationma PET recycling technology and the Amut online sheet production technology, no additional process stages are required. This is because the melt enters the Amut factory directly from the Vacationma 1716 T basic, without the need for bypassing to pelletize. The post-consumer PET material has been purified and pre-dried in the vacuum reactor of the Vacurema basic before extrusion, with an output of up to 1,500 kg per hour. After high-capacity filtration with an Erema SW-RTF recoil filter and online IV measurement, the melt directly enters the Amut online sheet factory, where it is processed into thermoformed sheets with a thickness of 0.15 mm to 1.2 mm. The single-layer thermoformed sheet produced from pure rPET not only meets 100% food contact standards, but also meets FDA and further regulations. At Alto, it is further processed into trays and food containers.

Amut has played a role by providing a full range of downstream equipment, from automatic T-die heads, three-roll stacking calenders with automatic gap control and electric cross-axis devices, laminating devices for welding and barrier films, thickness controllers to resistance Electrostatic silicon coating unit, fully automatic two-axis turret winder and online trimming, grinding and recycling.

The characteristics of the extrusion line come from the complete automation and simple management of the production line. This is because the new Amut software includes easy-to-start and easy-to-replace features, allowing the operator to start the extrusion line in automatic mode and change the product format.

Erema and Amut are long-term partners in the field of online sheeting. Erema's Vacurema technology is currently used in more than 100 Inline Sheet factories around the world, and is also used by Australia's Pact Group.
