To protect dry foods from the environment, they are often packaged in multiple layers. An outer layer, a barrier layer, and an inner layer are standard for many types of packaging. Depending on the specific requirements for barrier properties and shelf life of the product, two to five layers may be used, resulting in an enormous amount of waste. Together with Panverta CPP, Henkel Adhesive Technologies has developed films with an improved oxygen barrier layer that make it possible to reduce the number of packaging layers – a major step forward in terms of sustainability. From October 23 to 25, packaging manufacturers and brand owners can see the results of this collaboration for themselves at Henkel's booth 1C17 at Tokyo Pack 2024.

Flour, rice or pasta can quickly spoil or lose flavor when exposed to air, light or moisture. Packaging for dry foods must therefore be airtight, light-proof and moisture-proof. High-quality packaging solutions that meet all these requirements usually consist of several layers of different materials. These composite materials are often difficult to recycle because they cannot be easily separated. Henkel’s cooperation with PT. Panverta Cakrakencana, one of the leading film manufacturers in Indonesia, has successfully provided a solution to improve the oxygen barrier performance of metallized cast polypropylene (CPP) to less than 0.5 cc/m².day and CPP with aluminum oxide coating (AIOx) films to less than 8 cc/m².day. The jointly developed innovations ensure that these vital oxygen barrier properties for dry food packaging can be achieved when switching from multi-material designs to mono-material polypropylene (PP).
