Right: Stock produced a 1-litre oval container on a newly devel- oped injection moulding machine
The machine – developed
in partnership with mould- maker Brink Moulds & Automation and rPET supplier Alpla – was used to produce an oval 1-litre container made of 50% PET and 50% rPET. This container has a complex geometry and a tamper-evident, water- tight closure. Stork believes it is the first high-quali- ty 1-litre rPET container made for high-volume production. At Fakuma, Stork demonstrated the new
machine, paired with Brink’s custom mould, to produce the two-cavity container. “Stork and Brink have taken an important step in
providing a sustainable solution for the food packaging market,” said Gert Boers, CEO of Stork IMM. “This development reaffirms our commitment to delivering the technology that will support a circular economy.” EU regulations mandate the use of at least 35% post-consumer recycled (PCR) material in plastic packaging. This is a challenge for food packaging manufacturers because of the inability to use
recycled PP due to EFSA restrictions on permeabil- ity issues. R-PET has been used in blow moulded PET bottles for years, the injection mouldability of rPET has been an issue. Stork’s 440-tonne 4400-3550 unit can reach injection pressures up to 3000 bar and speeds up to 900 mm/sec to achieve consistent wall thickness. The machine’s capabilities are made possible by an optimised screw and valve geometry. Continuous, high-speed production results in a cycle time of 6.2 sec, producing 580 parts per hour. At Fakuma, Stork also focused on its geographic
expansion – including recent openings in the US and UK. �
