In order to sustainably expand our raw material base, Wipak is developing and introducing new sustainable solutions derived from renewable alternatives to crude oil-based materials. To maximize the sustainability of our films, Wipak is focusing its development on resources that do not compete with food sources.
For example, PAPER BTM® is a thermoformable composite made with 300 g/sqm paper and a 25 µm sealing layer. Based on the life cycle of the paper tray, its contribution to climate change can be reduced by around 55% compared to the previous concept. The PAPER BTM® film consists of 85% paper from FSC® certified sources and in many countries can be disposed of for paper recycling.
Wipak only processes FSC®-certified paper for food packaging. All our paper comes from responsibly sourced forestry and consists of 100 percent virgin fibers, and is thus free from mineral oils.
Paper Composite for Meat and Sausage Products
PAPER BTM® is a thermoformable composite made with 300 g/sqm paper and a 25 µm sealing layer. Extremely thin layers of plastic provide aroma protection, an oxygen barrier and increase the shelf life of the product. The lightweight nature of the paper tray also helps to reduce storage and transportation costs. Based on the life cycle of the paper tray, its contribution to climate change can be reduced by around 55% compared to the previous concept. For the 12.5 million trays, which are annually used, around 130 tonnes of plastic is saved. The Colruyt tray consists of over 85% paper and in many countries can be disposed of in paper recycling. The paper is FSC®-certified thus sourced from responsibly managed forests.
Polyethylen from Sugar Cane
Is it possible to use a high proportion of renewable raw materials in conventional packaging materials without changing its properties?
By using polyethylene obtained from sugar cane - so-called Green PE - it's possible to run renewable based PE down existing lines without constraining the machines. Sealing layers containing Green PE can be combined with any kind of printing substrates such as BOPP or paper. By combining Green PE into a composite using our FSC® certified papers we have developed a material containing approximately 75% renewable materials. Green PE also lessens societies dependency on plastics derived from oil resources and is 100% recyclable!

Squeeze Snack for Kids in “Green Packaging” – Freche Freunde as a Perfect Companion!
The Berlin start-up erdbär has a mission: to bring pep into the world of healthy baby and kids food with their “Freche Freunde” brand. “The goal is to develop an early friendship with fruits and vegetables - this is easiest when it’s made fun!” says Jan Augenstein from erdbär. But not only a funny design carrying the message. All products are made to organic quality standards without redundant additives. “It was clear for us that the packaging had to protect our product and fit in with our cheeky concept. We deliberately wanted to dispense with aluminum in our Quetschie pouches and use a sustainable packaging solution”, says Jan Augenstein. They decided on Wipak’s new Aluminium free concept for squeeze pouches - consisting of a combination of FSC®-certified paper and high barrier film. This composition comprises more than 30% renewable resources and even saves 25% plastic. The bold designs are printed with water-based inks using Wipak's innovative ProDirect® digital printing technology.
With the overall concept, erdbär underlines its responsibility for future generations and sustainably shapes the environment.
