US-based petrochemical company ExxonMobil has introduced a new oriented polypropylene (OPP) film that provides performance for oxygen-sensitive dry products requiring modified atmosphere packaging (MAP) such as fruits and nuts, cereals, snacks, roasted coffees and pet foods.
The new 21 micron Bicor MB866 OPP film, an extension of the company's transparent biaxially OPP Bicor films designed for flexible packaging applications, delivers gas barrier properties for MAP applications.
According to the company, the film features a polyvinyl alcohol (PVOH) coating on one side and an acrylic coating on the reverse.
To provide oxygen protection for prolonged product shelf life, the PVOH coating is reverse printed and adhesive laminated to a sealant film such as blown polyethylene (PE) or cast polypropylene (PP).
The film, with an oxygen barrier level below 1cc/m²/day features clarity, gloss and stiffness, delivers a barrier performance at the level of metallised polyester (PET) and higher compared to other barrier solutions that include polyvinylidene chloride (PVdC) or ethylene vinyl alcohol copolymer (EVOH) coated or coextruded films.
ExxonMobil said the PVOH coating's surface energy helps ink receptivity, while its chemical barrier contributes to reduced solvent retention.
The Bicor MB866 OPP film, which is currently available in Europe, Asia Pacific, the Middle East and Africa, uses solvent-free and chlorine-free coatings and provides protection from external contaminants and secondary packaging.
Bicor OPP films are available for use in laminates on vertical form fill seal (VFFS) and horizontal form fill seal (HFFS) equipment, besides featuring coating technologies that deliver good performance for food and nonfood packaging needs.
