A system including a liner implement that is configured to provide a lining for at least a receptacle, the liner implement includes an upper edge component having an outer surface portion and an inner surface portion. A retention strip implement engages the upper edge component, to tighten the upper edge component around an upper opening of the receptacle. A first end segment of the retention strip implement is configured to engage the outer surface portion of the liner implement. A second end segment is configured to engage the inner surface portion of the liner implement being operable for tightening the upper edge component around an upper element of said receptacle. An adhesive free area is configured to be operable for grasping during the engagement of the second end segment adhesive with the inner surface portion of the liner implement upper edge component.

A ring-peel-seal liner is revealed, the ring-peel-seal liner includes a metal sealing layer and an adhesive layer. The metal sealing layer has a first annular tear line, and is defined into an annular region and a central region by the first annular tear line, wherein the annular region encircles the central region. The adhesive layer is adhered on one surface of the metal sealing layer. With the ring-peel-seal liner described above, the issue of needing an additional liner for enhancing a sealing effect after opening a conventional packaging container is resolved.

Provided is a method for producing a self-adhesive to be arranged on a package comprising a space to store contents and an opening by which the space and an outside communicate, wherein the opening is repeatedly openable and sealable by the self-adhesive that consists of a cross-linking material of a resin composition containing a (meth)acrylic acid ester copolymer resin having a glass transition temperature of −22.8° C. or more, and a crosslinking agent. The method comprises making the resin composition that contains the (meth)acrylic acid ester copolymer resin, and the crosslinking agent, the resin composition being either emulsion or dispersion; and cross-linking the resin composition.

A tamper evident sealable plastic bag having front and rear walls terminating into front and rear flaps with handle openings at the mouth end of the bag and forming a holding cavity at a bottom closed end thereof. The side edges of the bag below the flap region are sealed. An adhesive closure system positioned below the flap region extends laterally from one side edge of the bag to another that can be deployed by removing a protective liner covering an adhesive strip for substantially closing off the mouth end of the bag thus providing improved security and tamper resistance. The bag can be opened by tearing along a perforated line. The bag walls include a plurality of slits for venting steam emanating from hot foods. In embodiments, tear initiation slits are utilized in tandem with perforations to provide a convenient method for opening the bag.
