Fully paper pouches usually cannot be heat sealed. Only paper with a sealable inner layer can be sealed using an impulse sealer or band sealer. For 100% paper, practical alternatives for closure and hygiene include a tin tie, adhesive strip, a label as a closing seal, a drawstring closure, or a tight fold with tape. On request, we also supply paper with a PVA layer. This allows a paper pouch that can be heat sealed and, with the right paper to PVA ratio, can still be accepted in the paper stream in many municipalities. We are happy to advise on the right specifications, the required barrier and suitable sealer settings for your product.
