Package for microwaveable popcorn, method for production of the package, and apparatus for sealing the package

摘要

Corn kernels (32) packaged within an elongate bag (10) can be popped within a microwave oven. The elongate bag (10) is either a lay-down or stand-up bag made from a laminate of two papers (40,42) with a metallized polyester film (30) between the two paper layers (40,42) at a location where the bag (10) will contact the floor of the microwave oven. The bag (10) is provided with a seal (52) across its top end (12) having at least one weakened portion (54) aligned with the gussets of the bag (10), whereby the at least one weakened portion (54) opens and permits vapors to vent from the bag (10) after a predetermined pressure within the bag (10) is reached. A method of preparing the package of corn kernels and an apparatus for sealing the bag filled with corn kernels is also disclosed.
