Toray’s OPP and PET films (go to http://www.toraytpa.com/Metallized-Lamination-Film) are metallized in-house, which ensures quality control and eliminates the time and expense to have films metallized by a third party. Metallization significantly impacts the oxygen and moisture barrier, makes for an opaque barrier to light, offers a high-reflective glossy aesthetic, and opens up new packaging application options—for example, those where foil might be the traditional choice.
MetPET is excellent for replacing foil in high oxygen-barrier packages and lidding applications for dairy foods, like yogurt or ice cream, or for items like applesauce or puddings. In comparison with foil, it offers better economics, improved barrier durability, and superior puncture resistance.
MetOPP has excellent moisture barrier, very good oxygen barrier, barrier to light, a highly reflective gloss, better puncture resistance in relation to MetPET and foil, and excellent flex-crack resistance, all of which can be achieved at a relatively low cost. It tends to be popular for salty snacks, cookies, crackers, nutritional bars and higher-end snack food packaging applications.
MetOPP is often designed with a low SIT heat seal layer, allowing it to be used in a two-layer lamination. MetPET doesn’t always have this type of heat-seal functionality and is often utilized in a triplex laminate.
