Lidding films specialist KM Packaging Services has introduced a new steam venting product which is compatible with polypropylene trays packaging ovenable meals and snacks.
The new film can be supplied as peel seal or weld seal, with or without KM's anti-fog treatments. In addition, 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 hole cluster can be placed in virtually any specific position on the lid, depending on the contents of the tray and the desired ventilation effect - and can even extend to several hole clusters on one lid.
KM's commercial director Graham Holding explains: "Our new steam venting film not only helps to maintain the freshness of frozen or chilled ready meals, but also encourages faster cooking. It's not just for lidding either - we can also supply roll-fed bags for vegetables, and any of the films can be printed to promote branding whilst saving on unnecessary additional packaging."
