KM Packaging Services steam venting film

KM Packaging Services has launched a steam venting product for ovenable meals and snacks. The film is compatible with polypropylene trays and can be supplied as peel seal or weld seal, with or without KM’s anti-fog treatment.

A high oxygen barrier is available, where venting holes in the film are coated to prevent air getting in or out, hermetically sealing the tray. On heating in a microwave oven, the coating softens to facilitate ventilation. Alternatively, pepper pot holes can be created in the centre of the lid, allowing steam to escape but keeping the seal intact. The cluster of holes can be placed in virtually any position on the lid, depending on the contents of the tray and the desired ventilation effect.

The steam venting film is designed to maintain the freshness of frozen or chilled ready meals and also to encourage faster cooking. As well as lidding applications, the film can also be supplied as roll-fed bags for vegetables and can be printed to promote branding.
