- pe-coated papers for bubble envelopes
WisaMail basic is an extra strong mailing material for bubble envelopes, offering excellent protection for the delivery of fragile articles. The mailing material is available in a wide selection of color shades that can be combined with other mailing materials from UPM. The combination of paper with optimal stiffness and polythene with low melting temperature ensures good runnability. The smooth and glossy paper surface provides a good printing surface.
- reinforced laminates for pockets and gussets
WisaMail Classic is a laminated, strong mailing material that withstands rough handling by postal and freight services. It has been developed especially for pockets and gussets. Thanks to the polyethylene component of the laminate, the final product provides a good barrier against moisture. A scrim reinforcement gives WisaMail Classic extra durability necessary in excessive handling.
New development of smooth and strong laminates
The focus of development has been to create good strength properties combined with a good paper surface. The new qualities have been developed together with UPM's envelope paper team and all papers used come from the UPM Mail family.
The market has shown keen interest, particularly in the growing field of e-commerce, where extremely strong mailing material is in high demand. The number of intercontinental mail shipments which require extra strong envelopes and bags is also increasing.
