High Temperature Stand-Up Oven Bag

Abstract

An improved oven bag for use in food cooking applications and a method of making an improved oven bag. The oven bag includes a bag-like body having a closed bottom end, one or more side walls extending upwardly from the closed bottom end, and an open top end. The closed bottom end may include a gusset which allows the bag to stand-up on its own thereby making it easier for the consumer to place food in the bag. The oven bag may include an easy to use closure system to close and seal the top opening. The closure system may include a flap portion on one side of the top opening and a high temperature adhesive disposed proximate the top opening on an opposite side of the top opening. The oven bag may also include a venting system in an upper portion of the bag. The oven bag may also include an easy opening tear-off system in an upper portion of the oven bag. For example, the venting system may include a series of perforation holes located beneath the closure system. The perforation holes may help with the venting of the oven bag during cooking and additionally may act as an easy opening system, by for example tearing-off the portion of the bag above the perforation holes, after the food has been cooked in the oven bag.
