Sappi Alfeld GmbH

Protected food, more sustainable packaging

Resources-saving materials that are easy to recycle have become decisive when it comes to choosing suitable packaging for branded goods. As a trendsetter in paper-based packaging with integrated functions and as the world’s leading provider of sustainable solutions, Sappi now offers its customers even more possibilities with the optimised papers in its Sappi Guard family.

Sappi Guard M has a mineral oil barrier and, with Kit 11, a very high grease barrier. Sappi Guard MS also impresses with its heat sealability, eliminating the need for additional production steps and materials as sealing media. The grease barrier is Kit 7. Sappi offers both papers in two variants: “Nature” is uncoated and has a natural, more tactile feel, whilst “Silk” stands out with enhanced printing results and a silky matt appearance.

Brand owners can use the four sustainable paper solutions from the globally available Guard family as primary or secondary packaging for dry and slightly oily foods such as pasta, rice, cereals and various powders. Guard M barrier papers are also suitable as liners for transport packaging, as they prevent mineral oil from recycled cardboard and paper from migrating into the food. At this year’s FachPack and with the aid of various practical examples, Sappi will show how diversely and versatilely the optimised barrier papers can be used.

Paper-based packaging solution with integrated heat sealability

Reducing the consumption of fossil resources in packaging is a major concern for Sappi. For this reason, the company has invested for many years in the development of packaging papers with additional features, such as barrier properties and heat sealability. This also applies to its latest product innovation: Sappi Seal, a functional paper with integrated heat sealing functionality and a dispersion coating on the reverse side. It can replace papers with a PE coating and, compared with existing packaging solutions, uses up to 50 per cent fewer fossil resources. Additionally, production also results in 48 per cent less CO₂ emissions (source: Ecochain).

The heat-sealable packaging paper has excellent sealing qualities and also an acceptable moisture barrier against water vapour. Sappi Seal also amazes with impressive printing results. And especially important for consumers, flexible packaging produced with Sappi Seal can be opened very easily and accurately.

This functional paper is ideally suited for both primary and secondary packaging. Food – such as sugar, tea and sweets – can be packaged just as well as non-food products, such as children’s toys and DIY products. The paper is currently available with a grammage of 67 g/m². Various application examples will be presented at FachPack.
