Sappi updates hot seal packaging paper

Sappi has announced Sappi Seal, a second-generation packaging paper with integrated sealing functionality. This new version promises improved sealing properties and is also recyclable in the paper waste stream.

Sappi Seal is a second-generation packaging paper with integrated sealing functionality.

The idea is that this can be used as a more environmentally-friendly option instead of a hot seal laminate made from plastic. Sappi Seal is a 67gsm paper that is coated on one side and has been finished with a dispersion coating on the reverse side that Sappi says gives good results with hot sealing.

As well as hot sealing, it also has a decent barrier against water vapour. It’s aimed at both food and non-food sectors and can be used for primary packaging, such as sachets, but also secondary packaging, such as flow-wraps for sweets, toys or DIY goods.

Sappi claims that users will be able to open this kind of packaging easily and smoothly, without uncontrolled tearing. It has a natural appearance and is said to offer good printability and finishing properties with all common finishing techniques.

René Köhler, Head of Business Development Packaging and Speciality Papers at Sappi, comments: “Brand manufacturers as well as consumers are looking for alternatives to plastic packaging materials. Sappi Seal will contribute to the use of more resource efficient and renewable materials for flexible packaging.”

Sappi Seal is available with FSC or PEFC certification and was produced according to the requirements of recommendation BfR XXXVI  (Bundesinstitut für Risikobewertung – Federal Institute for Risk Assessment). Further details from
