A resealable package integrity closure includes a lamination of films comprising a layer forming a top of container and having a scored flap defining an access opening to gain access to the contents of the container. The score that defines the opening flap cuts only into the outer layer of the film lamination and not through the sealing layer of film. A pressure-sensitive label functions as a sealing panel which completely covers the flap of the laminated film layer. A releasable adhesive is provided a pressure sensitive label that is applied over the film layer forming the top of the container. The pressure-sensitive label provides a sealing panel which is releasable from the film layer outside the perimeter of the score by peeling back the sealing panel. After opening the flap, the sealing panel of the pressure-sensitive label is reclosable against the top to seal the access opening.

The present invention is related to a reclosable packaging container comprising a flexible laminate with a build-in opening and reclose feature, said laminate comprising an inner structure and an outer structure, adhesively joined face-to-face by a permanent adhesive, a pattern of pressure-sensitive adhesive being integrated between said inner and outer structures, the pressure-sensitive adhesive being entirely covered by the permanent adhesive, the outer structure forming the outer surface of the container and the inner structure forming the inner surface of the container, the outer structure comprising an outer flap portion delimited by a scoring linethrough the outer structure, and an inner structure comprising an inner flap portion delimited by a scoring line through the inner structure, the inner score line (6) and the outer score line creating an opening into the container when the flap portions are peeled back, a marginal region of the outer flap portion extending beyond an edge of the inner flap portion and overlying an underlying surface of the inner structure, the inner and outer flap portions being joined with the permanent adhesive and the pressure-sensitive adhesive being disposed between the marginal region of the outer flap portion and the underlying surface of the inner structure for attaching and re-attaching, in use, the outer flap portion to the underlying surface, wherein the sum of the layer thickness of the permanent adhesive and the pressure sensitive adhesion within the pattern is higher than the layer thickness of the permanent adhesive outside the pattern.

A packaging device incorporating a breathable peel / reseal film and enabling a preservation process for allowing for the distribution, storage and multiple servings of a food product, particularly perishable food product(s), and initiating and controlling the transmission rates, respiration rates or deterioration of the perishable food product(s) and thereby, maintaining good internal and external food quality and normal development of flavor and aroma characteristics. The packaging device includes a plurality of atmospheric control attributes that modulates or controls the atmosphere within the packaging device as the food product(s) respire in order to promote the extended shelf-life of the food product and the maintenance of the quality and desirable marketable characteristics of the food product. The atmospheric control attributes can include perforations that may be positioned in breathable peel / reseal film portion of the package to allow the product respiration for multiple servings without substantially altering the shelf life extension properties of the packaging device.

A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing.

The invention relates to a packaging with a base body, that includes a compartment, and a closing flap. The closing flap includes a substantially shape-retaining, bent end area that is dimensioned and configured such that the end area reaches at least partially around a front surface of the base body in the closed state of the packaging.

A resealable packaging bag, in an embodiment, includes rigid side walls and a resealable flexible flap having a raised pull tab for use by a consumer to allow the flap to be attached to the bag Flip open the bag, then reseal the bag by placing the flap back over the opening. The edges of the peelable flap are coated with a resealable adhesive, while one side or end of the flap is attached to a portion of the front surface of the bag. The tab portion of the flap can mate with an opening, such as a slot, at the top end seal of the bag. Once the pull-tab is engaged with the opening, the flap is held back out of the way of the opening so that the flap does not interfere with the consumer's access to the product, and so the flap does not drop back onto the surface of the bag when not intended to inadvertently close the bag.

A bag with handle and method for producing the bag that incorporates the features of four seal bag body with a new handle part to obtain a new bag with a durable bag body that can carry a heavy load, can be stacked in high number without falling, consume less space in storage and transportation, has large front space and side spaces for product information display while on shelf, that is convenient to hold, strong and secure, that does not cut fingers in use, and that may be applied to shopping bags or reusable or resealable packaging bags. The concept of the method of producing said bag is steps of folding, assembling, and sealing a plurality of sheet materials which are not obvious to a person ordinarily skilled in the art.

A tamper-evident package utilizes a transparent resealable adhesive structure such as a tape or a label to cover the closure opening. Upon a first opening of the package frangible portions of the package front between adjacent arcuate cuts and slits defining the opening are torn. This tearing distorts the packaging film so that re-registration of the opposing lateral edges upon reclosing is not possible. This results in a package which is visually tamper-evident. The tamper-evident condition can be enhanced by graphics or other printing on the front of the package in the area of the closure to make the misalignment of a resealed closure viewed through the transparent structure more visually apparent. In one embodiment of the invention a series of arcuate cuts are centered laterally and are flanked on the right and left sides by two continuous wavy slits which form a portion of the closure opening.
