Ahlstrom-Munksjö launches PurposeSeal™ heat seal technology

HELSINKI (News release) -- Ahlstrom-Munksjö has pledged to create sustainable, fiber-based solutions. PurposeSeal™ is pushing the boundaries of fiber-based end-use applications.

PurposeSeal™ is a heat-sealed paper carefully constructed to ensure quality and protection for end-use packaging solutions. It boasts additional sustainability benefits when applied to Cristal™ Transparent Packaging Papers or trulyNatural™ unbleached papers.

Ahlstrom-Munksjö recently received recyclability certification for the Cristal™ transparent paper product family, including PurposeSeal™ technology. These products have passed the SBS Equivalency (WMU SBS-E) testing protocol certifying these innovative papers recyclable from Western Michigan University. Additionally, Cristal™ and PurposeSeal™ have obtained 3rd party certification from Centre technique du papier, certifying Cristal™ heal seal coating is recyclable to the European Union's EN13430 standards.

"PurposeSeal™ is changing the way our customers can create sustainable packaging solutions," said Zack Leimkuehler, Vice President of Ahlstrom-Munksjö's Technical Solutions business. "Excess waste and chemicals are removed from the converting process, as the strong seal is achieved using only heat."

"PurposeSeal™ is completely customizable," said Dana DeCoster, Marketing Manager of Ahlstrom-Munksjö's Technical Solutions business. "It can be combined with other technologies such as color, transparency, water resistance, and high stretch, along with other attributes to fit any requests your customers may come to you with."

While consumers continue to demand products with a positive end-of-life story, PurposeSeal™ can be a sustainable alternative to traditional film-based packaging. PurposeSeal™ is versatile enough to work in a variety of applications including, but not limited to, flexible packaging, insulated packaging, pouches and garment bags/wraps.
