A resealable package configured for heating in a microwave oven having at least one vent capable of relieving an internal pressure from an interior space of the package during heating. To protect the integrity of a resealable fastener, such as a zipper reclose feature, the at least one vent is capable of functioning at a low pressure below about 3.0 psi and preferably below about 1.4 psi. The at least one vent includes a specifically shaped outer portion and inner portion integrated into a package seal to allow for a controlled rupture or separation of this seal at the location of the at least one vent. This at least one vent can be formed directly into a seal of the package through a specifically shaped seal bar used during package formation.

Microwave package with low pressure venting feature

A package includes a first adjacent edge, a second adjacent edge, and a fitment seal including a fitment. The fitment seal is inclined at a fitment seal angle relative to the first adjacent seal, and connects to the first adjacent seal and the second adjacent seal. The package further includes at least one supplemental seal extending towards the first adjacent seal. The at least one supplemental seal is inclined at an angle from 90° to 180° relative to the first adjacent seal.

Package with supplemental seal

A thermoplastic flexible package includes a first non-shrinkable panel, an opposing second non-shrinkable panel, a first shrinkable panel and an opposing a second shrinkable panel. The panels are connected longitudinally with panel seals. The first non-shrinkable panel and the second non-shrinkable panel each forms a gusset. A first seal connects the first shrinkable panel and the second shrinkable panel in the transverse direction at or near the upper edges. A second seal that opposes the first seal connects the first and second non-shrinkable panels and the first and shrinkable panels in the transverse direction at or near the lower edges.
