Sappi has launched the second generation of its flexible packaging product with improved sealing properties, which is also recyclable.
Sappi Seal is single side coated and has been finished with a dispersion coating on the reverse side, which the paper giant said achieves good results with hot sealing.
It is designed to replace hot seal laminates made from plastic with materials containing a high proportion of renewable raw materials.
It has been 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 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.
René Köhler, head of business development packaging and speciality papers at Sappi, said: “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.”
