B+K has launched a completely biologically degradable film for hygiene packaging onto the market. The film material is based on corn starch and therefore meets increasing market demands regarding the use of regenerative raw materials. The packaging can be used in diverse applications and can be provided with high-quality printing. It breaks down completely in industrial composting facilities.

To achieve this, Bischof + Klein has developed a film recipe for white pigmentation which is also completely biologically degradable. Over the course of six to twelve weeks, the packaging breaks down completely in an industrial composting facility, thereby meeting the stringent DIN CERTCO regulations concerning biologically degradable products. The packaging material has accordingly been certified under registration number 7P0230.

In addition to hygiene packaging, the new, basic film can also be used to manufacture packaging for diverse market segments and applications. Although the material is currently still more expensive than conventional polyethylene films, B+K can foresee a viable future for corresponding products, particularly as the film can be provided with high-quality printing without optical restrictions.

The development of a biologically degradable collation shrink film ShrinkFlex® bio, which is used for multipack beverage packaging, is also promising. This material, which is also based on starch, offers another distinct advantage: It requires significantly less energy for the shrinking process. Environmentally-friendly packaging is a vital purchasing argument for an increasing number of consumers. Bischof + Klein is acknowledging this trend with its environmentally-friendly developments.
