PET Sheet Lines: Fit for recycled material thanks to retrofitted line components
Key components and know-how for plant optimisation in sheet extrusion
In order to be able to meet these requirements, many processors are confronted with high investment costs for equipment that can process recycled materials. After all, the quality of the end product must be good.
An ideal possibility to combine low investment costs with an extended processing window for recycled material is offered by Gneuss Kunststofftechnik GmbH from Bad Oeynhausen with a special retrofit service.
One of the companies that has used this service is Cotnyl S.A. from San Martín, thus being the first company in Argentina to obtain local approval to produce packaging made of 100 % r-PET.
Retrofit as an economic alternative to new investment
This increased use of recycled materials poses problems for many packaging manufacturers. A recycling rate of up to 100 % and the required recyclable design do not always meet the requirements for packaging, especially for food packaging.
Food authorities and consumers expect the highest quality in terms of colour, purity, odour and mechanical properties. The desired properties often cannot be achieved with existing equipment designed for processing virgin materials. Investments in completely new lines, with which the processing of recycled materials is successful, are not always possible for economic or space reasons.
An interesting alternative is the Gneuss retrofit.
