see what’s inside: transparent and heat-sealable paper for food and non-food

Whether it’s a sandwich, soap, or a toy car, consumers are accustomed to being able to inspect a product through the packaging, or at least through a viewing window, before purchasing. Therefore, delfort is launching thinwrap transparent gloss HS, a transparent paper. “It’s heat-sealable, recyclable, and certified for direct food contact,” says Peter Hackl, Head of Packaging at delfort. The new paper will be presented at Fachpack at the end of September.

“With our new thinwrap transparent gloss HS, you can now create viewing windows or even fully paper-based packaging without compromising protection, sealing performance, or product presentation,” says Hackl. A key technical feature is the fully coated surface with an A-A heat-sealable solution. This allows a single roll format to be used for different packaging sizes and types – both printed and unprinted. “This simplifies operations,” says Hackl. Furthermore, the paper has a glossy surface and a good grip. It allows for high-quality printing using common printing processes such as flexographic and gravure.

thinwrap transparent gloss HS is made from FSC- and/or PEFC-certified and controlled pulp. It contains no intentionally added PFAS and meets the requirements of the US FDA and the German Federal Institute for Risk Assessment (BfR) for direct food contact.

The range of applications for thinwrap transparent gloss HS is broad:

Food: The paper can be used as a transparent window for packaging to-go foods such as sandwiches and wraps, or as a flow pack to protect products presented in trays on the shelf (flow packs).

Non-Food: Applications for thinwrap transparent HS gloss include toys, cosmetics, body care products, clothing, or as a wrapper for magazines.

delfort will be exhibiting its barrier and transparent papers at Fachpack.
