In 2016, Sappi was the first manufacturer to launch
an 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. Now Sappi is
introducing Sappi Seal to the market, the second generation of this flexible
packaging solution with improved sealing properties, which is also recyclable.
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," says 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.
Sappi put great emphasis on user-friendliness when
developing this paper. As a result, Sappi Seal can be opened easily and
smoothly, without uncontrolled tearing. Its homogeneous and light surface
provides good printability and finishing properties with all common finishing
techniques. Its natural appearance and pleasant feel ensure an eye-catching
brand presence. 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).
Sappi Seal is available with a grammage of 67 g/m2.
