New PET strapping technology


The starting material was 100% commercially available, low-quality post consumer PET flakes that had been merely cold washed. In further customer trials, tensile strengths above 600 N/mm2 have been achieved continuously under regular stretching conditions.

The modified and patented Vacurema technology makes this possible by processing the bottle flake in a single pass with virtually no viscosity loss and stable IV, even in cases where the moisture content of the feed material is up to 1.5%. The throughput of the plant demonstrated at Erema is up to 300 kg/h of high-strength strapping band. The system, which is also suitable for making PET filaments from washed bottle flakes, can also process pure virgin material and mixtures of virgin material, bottle flake and strapping production waste in any ratios.

- The use of PET strapping worldwide is currently growing at a rate of around 15% a year. The production of high-quality PET strapping from washed bottle flake is an attractive and profitable business opportunity - and will continue to be also in the future - says Aldo Mingozzi, managing director at Techno Plastic, describing the reasons behind the cooperation with Erema. - As we showed together at this Open House, producers of PET strapping who use the new Vacurema inline strapping technology have considerable quality and productivity benefits that make this system stand out clearly from all other PET strapping plants offered on the market so far." In the future, turnkey plants with the combined Vacurema Tight Strap Technology for the production of PET strapping band and PET filaments from cost-effective post consumer bottle flake will be offered by both partners, Erema and Techno Plastic.

Since it was founded in 1983, Erema Engineering Recycling Maschinen und Anlagen Ges.m.b.H has specialised in the development, production and worldwide distribution of plastic recycling systems and technologies for the plastics processing industry.

With sales companies and offices in the USA, China and Japan, plus around 40 representatives in all five continents, Erema provides custom recycling solutions to match almost any individual application requirements. Innovative, stable technology and global service support ensure that owners enjoy the maximum benefit from their machines.

Erema's technology has become established as the global, leading standard for a wide variety of recycling tasks, ranging from the recycling of polyolefins to polyester (PET). The global market leader from Austria is 100% privately owned and currently produces around 300 plants and systems every year with a workforce of 350 employees.
