A new sealing polymer can help food processors produce stronger,
more "cost-efficient" packaging, claims its manufacturer.

Kraton Polymers said it has developed hydrogenated styrenic block copolymers for use as tie layers inbarrier packaging. A poor seal can result in a lowered shelf life for a product and packaging thatmay not stand up to the rigors of transport.

"Food manufacturers are continually looking for ways to extend the life of their products and cut down manufacturing costs,"​ saidcompany executive vice president Kevin Fogarty. "With Kraton's focus on new tie layer technology, we believe they will now be able to produce stronger, more cost-efficient packaging solutions."

The new tie layer technology specifically targets high performance barrier packaging, such as stand up pouchesand clear retortable packaging.

Tie layers are used by packaging manufacturers in coextrusions to bond dissimilar materialstogether. These include barrier materials such as nylon and ethylene vinyl alcohol polymer (EVOH ) and seal materialssuch as polyolefins.

Kraton has also side it has developed new grades within its G polymer product line. The new linesimprove the clarity and puncture resistance of films, the company stated in a press release. The newgrades also have better heat resistance when compared to conventional tie layer materials, Kratonclaimed.

"This new packaging option provides manufacturers with reduced costs and increased savings along the entire value chain by reducing waste and transportation costs, and by increasing the recyclability ofscraps,"​ the company stated.
