What are they?

Over the past few decades, nearly every aspect of food production has evolved to optimize resource efficiency and ensure product protection. At Sealed Air, we are dedicated to building a sustainable, safe, and nutritious food supply chain. Through innovative solutions like CRYOVAC® brand Darfresh® packaging, we, along with our strategic equipment partners – empower you to lead in a marketplace where sustainability throughout the distribution cycle is more critical than ever.

The Darfresh® skin packaging system is available in two innovative options: Darfresh® on Tray and Darfresh® Rollstock.

Darfresh® on Tray is a case-ready vacuum skin packaging system based on tray sealing technology with pre-made trays. It is a zero-scrap solution developed by Sealed Air and G. Mondini S.p.A. The Darfresh on Tray solutions range offers a wide array of top webs compatible with diverse types of trays, like rigid mono-PP, mono-PET, PP or PET-based trays as well as cardboard support.

The system provides a multitude of benefits including aiding in the reduction of plastic versus conventional tray skin and food waste by extending the shelf life of food products (versus MAP) from processor to retailer and consumer. The top web creates packaging that surrounds the product, preserving colour, flavour and integrity. Its highly formable characteristics act as a second skin, creating a high-quality, premium look that offers today’s consumers the product visibility they desire to verify the freshness themselves while enhancing point-of-sale appeal at the retail case.

Darfresh® on Tray zero scrap packaging systems are suitable for the following applications: fresh red meat, poultry, smoked and processed meat, cheese and ready meals, and lightly marinated food.

Darfresh® Rollstock is a thermoforming vacuum skin packaging based on standard Darfresh® technology. Our unique system utilizes specially formulated materials and dedicated machines - we cooperate with Ulma Packaging to deliver the best solutions to our customers.

Designed to provide a skin-tight effect around your product, our solution ensures evenly distributed pressure through a seamless vacuum process. Not only does this preserve the original shape of your product, but it also creates a complete contour seal, giving your goods unbeatable protection. When it comes to keeping your products protected and presentable, we’ve got you covered—literally!

What problems do they solve?

Consumers and retailers are demanding higher food safety standards, less food waste, and reduced plastic usage from food processors. At the same time, the industry faces increasing pressure to optimize costs and improve profitability.

The shift toward a circular economy is pushing food processors to adopt smarter resource management practices to achieve sustainability goals. Additionally, the rise of the omnichannel business model requires packaging solutions that can meet the diverse demands of physical stores, e-commerce platforms, and long-distance distribution.
