Sappi launches paper-based packaging solution with integrated sealing functionality
An innovative paper for flexible packaging with improved sealing properties and increased sustainability.
Sappi introduced Sappi Seal to the market, the second generation of its flexible packaging solution with improved sealing properties, which is also recyclable. In 2016, Sappi manufactured innovative packaging paper with integrated sealing functionality. This innovative and sustainable packaging solution generated a great deal of interest in the market and has gradually been developed further.
It is designed to replace hot seal laminates made from plastic with materials containing a high proportion of renewable raw materials. Sappi Seal is single-side coated and has been finished with a dispersion coating on the reverse side, which achieves good results with hot sealing.
“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,” said René Köhler, head of business development packaging and speciality papers at Sappi.
Sappi Seal was developed for use as flexible standard packaging in the food and non-food sectors, where hot sealing properties are required. This includes primary packaging, such as sachets, but also secondary packaging, such as flow-wraps for sweets, toys or DIY goods.
In addition to its excellent hot sealing properties, Sappi Seal also provides a decent barrier against water vapour. The new speciality paper is also recyclable within the paper waste stream.
