Pouch steams into market

Consumers are steaming happy about the convenience of Amcor Flexibles’ (www.amcor.com) microwavable SelfVent Stand-Up Pouch for fresh, steam-cooked vegetables.

Thanks to the self-venting feature, the microwave-ready products require no preparation other than to put them into a microwave. As a result, SelfVent is an FPA double winner, taking Gold in both Packaging Excellence and in Technical Innovation.

The pouch is a combination of two- and three-ply laminates, combining PET, OPA (oriented polyamide, better known as nylon), and cast polypropylene. The material is flexo-printed on an eight-color press with gravure anti-fog coating applied.

According to Amcor, “the vent works by concentrating stress on the self venting seal through the pack and seal geometry. The heightened stress causes the venting seal to break open, revealing the venting orifice. This allows controlled evacuation of steam, while retaining enough vapor pressure inside the pack to facilitate steam cooking of the product.” Amcor claims that this method increases vitamin retention to a degree that’s even better than standard cook-in bags used for frozen vegetables.
