A blister pack includes a housing having a plurality of cavities and a cover sealed to the housing and enclosing the cavities. The cover includes a base layer, at least one security element, and a heat protection layer. The heat protection layer includes one of an amorphous polymer and a semi-crystalline polymer.

In various aspects, the present disclosure pertains to thermoformed webs that comprise polymer films having one or more thermoformed cavities contained therein, the polymer films comprising a polymer blend of amorphous polyethylene terephthalate (APET) and a copolyester that comprises (a) dicarboxylic acid residues (e.g., dicarboxylic acid residues that comprise terephthalic acid residues and, optionally, one or more additional dicarboxylic acid residues) and (b) diol residues (e.g., diol residues comprising ethylene glycol residues and, optionally, one or more additional diol monomer residues). Other aspects of the disclosure pertain to methods of forming such thermoformed webs, packaged products comprising such thermoformed webs, and methods of recycling such thermoformed webs.

A blister pack includes a housing having a plurality of cavities and a multi-layer film sealed to the housing and enclosing the cavities, the multi-layer film including a base layer, at least one security element, and a heat protective layer. The heat protective layer is comprised of one of an amorphous polymer material or a semi-crystalline polymer material and is positioned to insulate the at least one security element from heat applied to the heat protective layer during heat sealing of the multi-layer film to the housing, the heat protective layer functioning as a heat sink for protection of the at least one security element during heat sealing of the multi-layer film to the housing.

A method of closing a packaging tray comprises arranging a packaging tray between a lower tool and an upper tool of a sealing station, positioning a cover film above the packaging tray between the lower tool and the upper tool, and pressing together the cover film and the packaging tray by a lower sealing surface of the lower tool and an upper sealing surface of the upper tool cooperating with the lower sealing surface. During the pressing together, a connection is established between the cover film and the packaging tray along a sealing seam. While the cover film and the packaging tray are being pressed together, an overpressure is locally generated by supplying pressurized gas from a pressurized-gas source, the overpressure cooperating as a counterpressure with the lower sealing surface or with the upper sealing surface so as to press the cover film and the packaging tray together.

Described is an assembly (1) comprising a wall element (2), defining a circumferential bonding strip (3) running over the wall element, and a flexible flat film connected to the bonding strip with a continuous circumferential bonding (4), which wall element and film define two opposite walls (2a, 5a) of a chamber (5), characterized in that the wall element further comprises a base plane B defined by the wall element, at least two corner elements (6a, 6b, 6c, 6d) positioned on a distance to one another, which extend substantially perpendicular with a height H (Ha, Hb, Hc, Hd) in the same direction from the base plane of the wall element, each corner element defining an angle A (Aa, Ab, Ac, Ad) of the chamber with an angle line which is substantially perpendicular to the base plane, strip sections (7a, 7b, 7c, 7d), each connecting two corner elements that define adjacent corners of the chamber to one another, the distance between the strip sections and the base plane being less than H, wherein the continuous circumferential bonding strip runs over the strip sections and over the corner elements and at least in the area of the corner elements at a distance from the base surface corresponding to height H (Ha, Hb, Hc, Hd), and wherein the outer contour of the film is shaped in such a way that the outer contour of the film corresponds to that of the circumferential bonding strip.
