New Metallized Heat-Sealable Opp Film Introduced

Toray Plastics (America), Inc. technology adds value to packet and stand-up pouch applications.

North Kingstown, RI - Converters and end users can now replace the foil and sealant in traditional paper-polyethylene-foil-polyethylene (PPFP) structures with a new, technologically advanced, heat-sealable, co-extruded, metallized OPP film. Toray Plastics (America), Inc.'s next generation PCFS, made with a proprietary blend of polymers, saves converters time and money by eliminating the sealant extrusion coating step in the converting process. The new MOPP film has a low shear storage modulus (viscosity of the molten resin) that provides increased flow-ability and improved hermetic seals. PCFS also has exceptional moisture and oxygen barrier durability, as well as improved economics over traditional foil and sealant combinations. PCFS is now a preferred, brand-building packaging material for packet and stand-up pouch applications, including hot cocoa, coffee, tea, seasoning, soup, rice, croutons, stuffing, dried cheese, powdered confections, and powdered beverages and nutrition/energy drinks.

"Converters and food manufacturers depend on new packaging technology to keep them a step ahead of the competition," says Chris Voght, product manager, Torayfan Division. "PCFS offers significant advantages by outperforming standard OPP and foil and delivering a heat-sealable, cost-effective, aesthetically appealing flexible package that has exceptional barrier durability."

The PCFS's unique, heat-activated sealant has a low seal initiation temperature and improved hermeticity versus sealants typically used in BOPP films. During the heat sealing process, PCFS exhibits a unique "caulking" ability to flow into corners and channels and around small particles in the seal. This eliminates the need for a polyethylene sealant in traditional PPFP structures, saving converters time and money in the converting process.

PCFS offers high barrier durability, whereas foil easily succumbs to pin holing. Pin holing is a greater risk today as converters try to save money by using even thinner foil. PCFS also exhibits excellent stiffness, puncture resistance, and improved dead-fold properties. These important physical attributes ensure a value-added, eye-catching appearance by preventing the "shop worn" look that typically occurs when handling packages made with foil.
