These solutions, which are frequently developed in collaboration with partner firms, can be produced consistently and efficiently on its whole line of traysealers, from the semi-automatic M-Flex to the fully automated Amaxseries. All machines combine excellent product safety with cost-effective consumables. This helps food manufacturers throughout the world launch sustainable packaging in retail. Here are a few recent examples from Europe.
EasyLid®: material-saving, reclosable tray
A Dutch producer of dairy products has recently brought an eye-catching packaging solution to the retail shelves. It uses SEALPAC’s EasyLid® concept for butter sold under private label at one of the country’s largest retailers. The EasyLid® solution combines a patented, injection-moulded, polypropylene (PP) tray, produced by Naber Plastics in The Netherlands, with a unique tray-sealing technology from SEALPAC. The tray has a common sealing edge, as well as an additional ring. A peelable seal is applied to the regular sealing edge, whereas the additional ring is hermetically sealed in the same process. As such, upon opening the tray for the first time, the lid functionality is automatically activated. It means that the additional snap-on lid, common for this type of packaging, is no longer required. Also, there is no need to invest in a lidding system that requires extra space and more personnel in the factory.
The EasyLid® trays are made of 100% PP, making them fully recyclable after use. At the same time, the packaging concept contributes to more resource conservation by reducing plastic waste, which has led to various international packaging awards. By switching to EasyLid®, the Dutch manufacturer achieved a 35% reduction in the weight of its packaging compared to the previously used solution with a tray, top film, and lid.
FlatMap®: sustainable, modified atmosphere packaging of sliced products
The FlatMap® packaging concept, used by a renowned German manufacturer of cold cuts, puts sliced meat, dairy and seafood products in the spotlights. These products are placed on a flat cardboard carrier made from bleached or unbleached fibre. The carrier is coated with a thin protective layer, which provides stability, as well as a reliable barrier against fat, moisture, and oxygen. The products are securely sealed under modified atmosphere by means of a thin lidding film, hence prolonging their shelf life.
Both the protective layer and lidding film are polyolefin-based, making them fully recyclable. Consumer-friendly opening of the pack is ensured by an easy-to-grip peel tab. Due to the perfectly flat design of the pack, an entirely new level of reclosability can be achieved. This ensures optimal freshness until the very last slice and enables first-class storage in the consumer’s refrigerator without the need for re-packing.
Another major benefit of the FlatMap® concept is the resource-saving use of materials. Compared to common modified atmosphere packaging, up to 75% of plastic can be saved. At the same time, recycling is improved. After finishing the product, the thin layer is easily removed from the cardboard carrier by means of a peel tab, to allow for disposal as plastic waste together with the lidding film. Obviously, the cardboard carrier is thrown away separately as paper waste. The cold cuts of the German meat manufacturer are presented vertically at retail, either hanging or standing. This provides full visibility of both the sliced meat and the attractively printed cardboard carrier.
eTray®: minimized plastic content for fresh food products in trays
SEALPAC’s innovative eTray® concept, which allows for efficient packaging of fresh food products under modified atmosphere with as little plastic as possible, is used by a renowned German customer in the fresh meat segment for goulash, pork schnitzels, and meat skewers.
The tray consists of two components: a high-quality cardboard base, which can be printed on both sides, and a plastic inner layer that purely provides the sealing and barrier function. Owing to the highly stable, uninterrupted sealing edge, each tray is reliably sealed under MAP on any of SEALPAC’s traysealers. The extremely stable eTray® is suitable for denesting and allows for smooth transport across the packaging line. Compared to common trays in the market, between 40% and 60% of plastic is saved, depending on shape and size.
After use, the plastic inlay can be easily separated from the extremely thin cardboard base, so that both components can be disposed of separately in their appropriate recycling streams. To create a resource-saving solution, the inner layer can be produced from mono PP or mono PET. As such, the concept fulfils the latest guidelines in German food retail, which requires packaging materials based on polyolefins. The eTray® packaging concept was implemented at the German meat manufacturer on its existing SEALPAC traysealer using the existing tooling.
