A packaging device allowing for the distribution, storage and cooking of various food products, such as perishable or frozen food product(s). The packaging device includes a plurality of micro-perforations that may promote the extended shelf-life of the perishable food product and the maintenance of the quality of the perishable food product or be configured to maintain the integrity of a frozen food product. The packaging device also includes a venting system that allows the cooking of the perishable or frozen food products within the packaging device.

To provide a microwave pouch that favorably prevents both of hole formation of the pouch and spurting of contents, with a simple structure. A microwave pouch (10) includes a self-venting mechanism (20). The self-venting mechanism (20) has an annular venting seal (30), a steam release part (40) surrounded by the venting seal (30), and a movable piece (60) defined by a slit (50) formed in the steam release part (40). The venting seal (30) has a seal peel initiation part (31) where peeling is started by steam generated inside the pouch (10) during heating. The slit (50) includes slit both ends (51), and a slit intermediate part (52) formed to extend from the slit both ends (51) toward a region away from the seal peel initiation part (31) and connecting the slit both ends.

A vented sealable bag comprises a container, a two-part seal and a vent. The container has opposing sidewalls and a bottom defining a cavity. The sidewalls form a neck defining an opening opposite the bottom, The sidewalls have an inner surface facing the cavity and an outer surface external to the container and the sidewalls have a thickness. A two-part seal is formed on the inner surface of the sidewalls adjacent the neck. The two-part seal has a hook formed on one sidewall and a clasp formed on an opposite sidewall. The hook and clasp are arranged on the inner surface of the sidewalls to form an airtight seal isolating the cavity from an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container. A vent is integrally formed in one of the sidewalls. The vent is further comprised of a dimple having a thickness that is thinner than the thickness of the sidewalls. The dimple is concave when viewed from the cavity and has a slit formed at an apex that is closed except when the container is sealed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.

A package includes: a film including a crystalline stretched oriented film; and a breaking portion provided in the film and including one or more non-oriented portions formed by heating a part of the crystalline stretched oriented film at a temperature equal to or higher than a melting point of the crystalline stretched oriented film and facing each other with an oriented portion of the crystalline stretched oriented film interposed therebetween.

In a method for cooking food in a container, in particular in a bag, the container, during heating, is opened at a particular overpressure of the medium and closed when the overpressure drops. A closing device is connected to the container and equipped with a pressure relief valve by means of which the container is opened at a particular overpressure of the medium and closed when the overpressure drops. The closing device includes at least one inner elongate retaining element and at least one sleeve body which surrounds the retaining element. The container is provided with an opening, and fed between the retaining element and sleeve body and through a longitudinal slit in the sleeve body. The retaining element and its surrounding sleeve body form the pressure relief valve. Optimal cooking of the food introduced into the container is achieved and fast preparation of the food is possible.

A packaging device including a breathable or non-breathable, microwavable composite film structure in the form of a bag, a tray or other type of container is disclosed. The device may include atmospheric control attributes in the form of microperforations, and steam venting mechanisms in the form of precision cuts or channels. The microperforations may form atmospheric conditions within the device for the storage of perishable and/or respiring food products, and the steam venting mechanisms may regulate the pressure and/or heat within the device during microwave cooking of the food products within.

Embodiments include a container with a leak resistant seal. The leak resistant seal provides access to the inside of the container when the leak resistant seal is open. The leak resistant seal includes first and second seal portions that are configured to be coupled together to close the container. A gap is arranged between ends of the first seal portion and the second seal portion, which provides an abutment that each of the ends of the first and second seal portions contact when the first seal portion is coupled to the second seal portion.

The addition of a colander functionality to a container generally designed to store and thaw or cook food products in the microwave, by adding a perforated area (holes, punctures, or slits) in an area to the container and sealing the area with a cover that can be easily lifted or released after thawing or cooking is completed to allow for the drainage of accumulated liquid and moisture. The addition of the perforated area and cover would typically occur during the manufacturing process of the container prior to the formation of the container or filling of the container with product.

Provided is a microwavable pouch having a rectangular outer shape in plan view. The microwavable punch includes an automatic steam release mechanism. The automatic steam release mechanism includes a steam release portion and a steam release seal portion surrounding the steam release portion, and assuming that there is an inscribed ellipse in contact with centers of inner edges of sides of a peripheral seal portion of the pouch, the steam release seal portion is formed so that a circumference of the inscribed ellipse is positioned in a width region of a seal separation start portion of the steam release seal portion closest to a center point of an accommodation portion or in a vicinity of the seal separation start portion.

A food wrap for wrapping ovenable foods includes a polyester layer having a thickness of about 12 μm having a first surface and a second surface opposite the first surface, a barrier layer comprising aluminum oxide covering at least a majority of the first surface of the polyester layer, a paper layer adhered to the barrier via an adhesive, where the paper layer has a grammage of about 35 g/m.sup.2, and a coating layer covering at least a majority of the paper layer, where the coating layer covers an ink label.
