Packaging roll films and preparation methods thereof are provided. A first transparent adhesive tape layer may be capable of covering a second high-adhesion layer such that the problem caused by the exposed second high-adhesion layer may be solved. The adhesive film and the non-adhesive film may not need to completely cover the second high-adhesion layer during the process. When the roll film is unrolled for packaging an item, the rolling drum may stop rotating at the end of a cycle of the previous packaging section; the item may continue to rotate due to inertia and thereby generate a tension force at the position where a previous packaging section and a latter packaging section are connected. A parting layer may be parted from the second high-adhesion layer, allowing the non-adhesive film on the latter packaging section to be unrolled, and enabling the adhesive film of the previous section to continue wrapping.

The present subject matter relates to a label lid for sealing an opening in a packaging container. The label comprises a facestock layer, a removable adhesive layer, a heat-seal layer, and an optional release coating, wherein the removable adhesive layer does not include a release liner. The removable adhesive layer can be coated on the heat-seal layer or the facestock layer. Optionally, a release coating can be applied to the heat-seal layer or the facestock layer. The composition of the layers used in specific arrangements provides unique performance characteristics for the label for improved sealing, reclosure, and matrix stripping properties.

A resealable package assembly is described. The package assembly includes a selectively positionable flap that covers an aperture or enables access through the aperture into the package. The flap and package include provisions for releasably engaging the flap to the package to seal the interior of the package. Provisions for grasping the tab and indicating whether tampering has occurred are also described.

Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.

A cover configured to cover an opening of a tray or container is provided. The cover may include a main panel and a pair of side panels, each side panel extending from opposing edges of the main panel. Each side panel may include an intermediate panel connected to the main panel by a fold line, and a side flap connected to the intermediate panel by a hinge line. The intermediate panel is at least partially secured to a bottom surface of the main panel. The side flap is configured to rotate away from the bottom surface of the main panel. A slot is formed between the side flap of the side panel and the bottom surface of the main panel. The slot is configured to receive an upper portion of the tray or container when the cover is positioned on the tray or container.
