A tearing device to be applied to a complete package (1, 2) is disclosed, consisting of an adhesive label having a base layer (3) provided with an adhesive portion and a terminal portion (32, 33, 34, 32′, 33′) acting as gripping edge for imparting a manual traction, the label being so arranged as to determine at least two points of localised application of the stress, or a point of application of the stress and a point of reaction to the stress, very close to each other, upon applying a traction on said terminal portion. A weakening line or a preferred-rupture line (4, 4′) may be provided, with the base layer being made of a material having an ultimate tensile strength higher than that of the wrapping sheath and a much lower tensile elongation than that of the wrapping sheath.

A packaging system includes an object, a heat-shrinkable package, and a protective film. The heat-shrinkable package is formed from heat-shrinkable film around the object and the heat-shrinkable film includes a weakened portion. The protective film is coupled to the heat-shrinkable film and positioned to cover the weakened portion in the heat-shrinkable film. The heat-shrinkable package is configured to shrink and form a package of heat-shrunk film around the object in response to being exposed to a heat-shrink environment. The protective film is positioned to cover the weakened portion in the heat-shrunk film after exposing to package of heat-shrinkable film and the protective film to the heat-shrink environment.

The invention comprises a package for reactive materials comprising a panel defining a first end, a second end opposite the first end, and at least two side edges. The panel comprises at least one film layer, an adhesive adjacent the film layer, wherein the adhesive is pattern applied such that it is disposed within an interior region of the film layer and wherein a perimeter of the film layer is adhesive-free adjacent each of the first end, second end, and side edges, and a release liner comprising a substrate layer and a cured silicone layer. The release liner is adhered to the film layer via the adhesive, the substrate layer of the release liner is disposed adjacent the film layer, and a perimeter of the release liner is smaller than the perimeter of the film structure. In an embodiment, the panel comprises a tubular body and the side edges are sealed together to form a fin seal, the first end is sealed closed to form an end seal, and the second end is sealed closed to form an end seal.

Described embodiments provide systems and methods for controlling the temperature of an item with a sheet. The sheet includes a front side and an obverse side, a first adhesive disposed along a first edge of the sheet on the front side of the sheet, such that when the sheet is folded over the item, the first adhesive engages with the front side of the sheet to create a container pocket having a container volume; and a second adhesive disposed on the front side of the sheet such that when the sheet is folded over the item, the second adhesive engages with the sheet to create a temperature control pocket with a volume less than the container volume. The sheet also includes a third adhesive for engaging with an ice pack, and a fourth adhesive and a fifth adhesive for creating side enclosures for the temperature control pocket.
