Producing products in a sustainable way is a marathon not a sprint. It is a continuous process not just a one-off final solution. It is a journey, the purpose of which is to constantly search for new, more environmentally friendly solutions while maintaining the full functionality of the packaging.
One of the traditional packaging solutions was already in 2019 a PET / PET met / PE composite, which can be found in various food segments. The Chemosvit Folie development team replaced the individual layers of the composite so that the physical and mechanical properties of the packaging were fully preserved.
At the same time, the number of laminate layers was reduced. Laminate based on PP – OPP ultra high barrier / Cast PP – can completely replace the classic structure and complements the company’s portfolio of packaging solutions that can be recycled.
The end customer may generally have difficulty with the correct sorting of composite packaging, in which a large amount of food is packaged. It is packaging that has polyesters with polypropylenes, polyamides, polyethylenes or aluminium films in the structure.
The customer will find it on shop shelves as packaging for cheese, coffee, meat products, nuts and much more. That is what we at Chemosvit Folie, together with food manufacturers, want to change gradually.
“We are looking for monostructural materials – i.e. materials composed of only one group of plastics or only one type of plastic, which would have all the necessary properties that packaged food requires,” says Eva Sámelová, a research and development specialist at Chemosvit Folie. “At the same time, however, we must also keep in mind that packaging lines must not reduce their performance, and the shelf life of the product must be maintained,” she adds.
