What do frozen fish fingers and cement have in common? Both must be packaged in a way that protects them against moisture. So it wasn’t a bad idea for the engineers at frozen food supplier Frosta to take a cement bag as their inspiration when developing their new, eco-friendly packaging. The inside of the bags for the frozen products is made of a highly compressed special paper; the outside a tear-resistant type of paper. There is no plastic coating at all. Starch is used to glue the seams.
Paper bag patent
The developers at Frosta worked on the idea for two years, CEO Felix Ahlers told the newspaper “Die Welt”. A patent application was filed for the fully compostable packaging. In January 2020, the company started selling its frozen meals in paper bags. For consumers, this means an additional cost of about 20 cents per package due to the more complex production process – and hopefully a reduction on their environmental impact: Frosta expects to save 320 metric tons of plastic per year with its new bags.
