Walki Introduces Paper-Based Frozen Food Packaging Portfolio | Article
Walki has has developed a portfolio of paper-based packaging, including printed solutions, for frozen food applications, which are intended to be recyclable into existing paper streams.
The portfolio includes the Walki EVO Seal and the Walki Opti Seal, which the company says are paper-based packaging specifically for pillow pouches for frozen foods, such as vegetables, seafood and baked goods. . Walki says the EVO Seal has a dispersion coating barrier against water vapor and grease, while Walki Opti Seal apparently has an optimized PE extrusion coating.
Walki claims that the EVO Seal and Opti Seal solutions are recyclable.
Andreas Rothschink, Product Development Manager at Walki, explains: “The dispersion coating makes Walki EVO Seal recyclable in the waste paper stream without any separation process, while the minimized PE coating on Walki Opti Seal makes it suitable for recycled with paper. with an acceptable fiber yield.
Additionally, Walki claims that its Lamibel MDO-PE is a film-based material for MDO film pillow pouches that is reverse printed and solvent-free laminated with low-tightness LDPE. According to Walki, MDO technology means that film thickness is minimized while performance is maximized by replacing other types of materials such as PP or PET films.
The company adds that Lamibel MDO-PE is suitable for all types of packaging, including doypacks, flowpacks and pouches. It can offer a packaging solution for frozen foods, including vegetables, sharp-edged seafood, and baked goods.
Rothschink comments: “This combination of two PE films makes the packaging fully recyclable in the plastics stream. Stretched film has better optics with high stiffness and mechanical properties than standard PE. The film can also be transparent, allowing the consumer to see the product.
Walki Pack Tray, the latest addition to the portfolio, is a cardboard-based tray apparently suitable for ready meals and designed to replace aluminium, plastic or laminated trays. Walki claims that the tray material is 100% PET-free and recyclable into the paper stream.
Dudley Jones, Consumer Sales at Walki, adds: “The tray is easy to fill, transport and store, and is also the convenient choice for the consumer as the fibre-based tray is safe to use in micro microwaves and in conventional ovens up to 220°C. degrees for up to 60 minutes.
Walki cites data that suggests the global frozen food market is expected to reach 322 billion euros by 2026. According to Jones: “Frozen foods are an ideal way to extend shelf life without losing vitamins. It’s also a great way to fight food waste. This is important because up to 9% of global carbon emissions can be attributed to food waste, especially fruits and vegetables.
Last year, Walki launched a range of ready-meal and frozen food trays that would be fully recyclable in paper streams.
