When the pack is opened, the tray and barrier film automatically separate. The tray, made from renewable raw materials, is disposed of with waste paper, while the thin barrier film goes into the recycling bin. Both materials are mono-materials and can be recycled as pure, separated materials — without any pre-sorting by the consumer.
Kallfass-Wrap®
Sustainable fresh packaging for the fresh food counter
Fresh food with a longer shelf life for the point of sale. Food can be packaged more sustainably and with far less plastic. Airtight packaging with the option to extract air and introduce a protective gas — that's what Kallfass-Wrap® offers. Modified Atmosphere Packaging (MAP) ensures a longer shelf life for food products.
The sustainable alternative for the fresh food counter
Kallfass-Wrap® is a plastic-reduced food packaging solution for perishable goods at the fresh food counter.
The name says it all: WRAP stands for Waste Reduction Alternative Package — a packaging alternative specifically designed to reduce waste.
The principle is based on the combination of two mono-materials: a tray made from renewable raw materials such as pulp or paper, and a thin barrier film with a thickness of just 20µ or 30µ.
Compared to conventional food packaging made from multi-layer composite material, which must undergo thermal recovery, Kallfass-Wrap® reduces the plastic content of a pack by up to 90% — without compromising on protection for the product.
Product examples
Barrier film and protective gas: freshness that lasts longer
The barrier film completely envelops the tray and its contents, hermetically sealing it with airtight seams. Outside air cannot penetrate, effectively preventing rapid spoilage of the food.
Optionally, a protective gas (MAP – Modified Atmosphere Packaging) can be introduced into the pack, which remains safely enclosed by the barrier film, further extending the product's shelf life.
The film thickness of 20µ or 30µ is selected depending on the required barrier performance and product weight. Despite the low material thickness, the barrier film reliably protects the goods from external influences and preserves freshness and quality all the way to the fresh food counter.
Simple recycling through automatic material separation
What sets Kallfass-Wrap® apart from conventional fresh food packaging is the consistent separability of the materials used. When the pack is opened, the tray and barrier film automatically separate from each other — without any extra effort for the consumer. The tray can be disposed of with waste paper, and the barrier film via the recycling bin.
Both materials can thus be returned to the recycling loop as pure, separated materials, significantly increasing the recycling rate compared to composite materials.
This makes Kallfass-Wrap® a true win-win-win solution: manufacturers reduce their plastic use and meet growing regulatory requirements, consumers can recycle more easily, and the environment benefits from less plastic waste.

Fresh packaging with a future
At the point of sale, Kallfass-Wrap® impresses with an appealing appearance: the transparent barrier film gives a clear view of the product and builds consumer trust at the point of purchase. Less packaging material doesn't mean less protection — it means a thoughtful reduction to the essentials.
For food manufacturers and retailers looking to future-proof their packaging strategy, Kallfass-Wrap® offers a proven, ready-to-implement alternative to conventional fresh food counter packaging.
FAQs on Kallfass-Wrap®
What does the name Kallfass-Wrap® mean, and what does the abbreviation WRAP stand for?
WRAP stands for Waste Reduction Alternative Package. The name describes the product's core principle: maximum protection for fresh food with drastically reduced plastic use compared to conventional fresh food packaging.
What foods and applications is Kallfass-Wrap® suitable for?
Kallfass-Wrap® was specifically developed for perishable foods at the fresh food counter — meat, fish, cheese, seafood, prepared meals, and similar products that require reliable barrier protection and, optionally, a protective gas atmosphere.
How does recycling work with Kallfass-Wrap®?
How much plastic does Kallfass-Wrap® save compared to conventional packaging?
The plastic content of fresh food packaging can be reduced by up to 90% with Kallfass-Wrap®. This is made possible by using a tray made from renewable raw materials instead of a plastic tray, as well as a very thin barrier film with a thickness of just 20µ or 30µ instead of a multi-layer composite film.
