A sterilizable pouch includes at least one sheet, wherein outer peripheral edges of the at least one sheet are sealed together to define a pouch having an interior space for receiving an article therein. A first releasable seam spans between a first peripheral edge of the at least one sheet to a second, opposite, peripheral edge of the at least one sheet, the first releasable seam dividing the at least one sheet into a first sheet part and a second sheet part. A second releasable seam and a third releasable seam each substantially span from a third peripheral edge of the at least one sheet to a fourth, opposite, peripheral edge of the at least one sheet and along the first peripheral edge and the second peripheral edge, respectively. The second and third releasable seams are arranged generally perpendicular to the first releasable seam, where the first, second and third releasable seams enable the pouch to be completely opened such that a device can be removed from the pouch without the device contacting non-sterile portions of the pouch.

A bag is formed in a gusset bag shape, and sections respectively extending along the short-side portions of a pair of front and back principal-surface film portions are each joined together as end joint portions, to thereby seal frozen food inside the bag. In each end joint portion: the pair of V-shape segments of a side-surface film portion, which is folded inward in a V-shape, is not joined together; and an end of the side-surface film portion is joined only to the ends of the pair of front and back principal-surface film portions extending along the respective short-side portions thereof, to thereby form a side joint region formed so as to expand in a V-shape, each side joint region being formed by joining the end of the side-surface film portion and the ends of the respective principal-surface film portions extending along the short-side portion thereof.

A flexible container includes a first panel formed from a flexible elastomeric material and a second panel formed from the flexible elastomeric material which is preferably a food grade silicone. The panels join together to form the flexible container and define an interior volume. A first closure and a second closure are provided along an opening defined at a portion of a perimeter of the flexible container, in which the first closure includes mating interlocking teeth and the second closure includes a mating rail and groove.

According to an aspect of the invention, provided is a bag-shaped container including a tubular film and at least one pair of engagement portions. The tubular film has an inner surface and an outer surface, and is folded in a manner that the outer surface configures both an inner surface of a bag body and an outer surface of the bag body. The at least one pair of engagement portions projects from the inner surface of the bag body, and engages with each other.

The invention is about a vacuum sealed preservation bag with an evacuation valve seat. With arranging the silica gel sheet, the first sealing strip, the second sealing strip, the buckle strip and the T-shaped groove, the rib strips implement the sealing by mutual friction, they are easy to separate under the action of external force, which causes the air to enter the sealed bag, affecting the using effect of the sealed bag is solved.

The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.
