Advances in Ultra High Barrier (UHB) and Enhanced Sealant (ES) Technology For Bi-Oriented Polypropylene (BOPP) Film, 2005 PLACE Conference

PressWeb.jpg

Advances in ultra high barrier and enhanced sealant technology have been combined to provide solutions for barrier packaging including foil replacement and seal through contamination not previously available with a BOPP film. Through modifications to the extrusion and orientation process and the addition of advanced sealant and metal adhesion polymers, ExxonMobil has developed grades of Metallyte® BOPP films with on oxygen transmission rate (OTR) of 0.006 cc/100 in2/24 hr, a water vapor transmission rate (WVTR) of 0.02 g/100 in2/24 hr and seals of >2000 g/in in lamination. These new films offer excellent aroma barrier, improved flex crack resistance over foil and the ability to seal through contamination, with enough seal integrity for "over the-mountain" distribution. In addition, the films have excellent hot tack and offer robust packaging ranges on both vertical and horizontal packaging equipment.
