Treofan simplifies laminate structure and boosts sealing performance of BOPP films

Treofan Germany GmbH & Co. KG, a leading global manufacturer of biaxially oriented polypropylene (BOPP) films, has developed a new 5-layer BOPP film using Vistamaxx™ performance polymers. Using Vistamaxx polymers in the heat sealable side of a new, metallized BOPP film simplifies the laminate structure, allows aluminum foil to be replaced and can reduce costs compared to market reference alternatives.

The new BOPP film was developed for the packaging of instant soups, but is also well-suited for any other kind of dehydrated powdered product such as spice blends or instant sauces. 

Simplified laminate structure
Treofan developed a metallized BOPP film, Treofan MSB 30, using Vistamaxx polymers in the heat sealable side. MSB 30 replaces the aluminum foil and PE sealant allowing the number of laminate components to be reduced from 3 layers to 2.

Sealing properties boosted
Market reference laminates offer a minimum seal strength of 5N/15 mm, which cannot be achieved with a standard BOPP film as the sealant. Treofan MSB 30-based laminate, however, offers a seal strength higher than can be achieved with a standard BOPP film as the sealant.
“Using Vistamaxx polymers to enhance the sealing properties has allowed us to enter new markets,” said Detlef Hütt, Innovation Engineer, Treofan Germany GmbH & Co. KG.
