During the manufacturing process the exterior surface of one or both of the sheets of plastic film which form the bags is treated with low temperature corona discharge plasma to raise the level of surface charge magnitude to at least 43 Dyne to increase the adhesion force between the bags. A recess is formed in each of the bags to further increase the adhesion. The increased adhesion causes the mouth of one bag to automatically open as the adjacent bag is removed from the rack. The recess is formed at the same time openings are created in the bags to accept the support rods of a dispensing rack. The bags can have simple edge sides or side gussets and may be provided in a package including a pouch which receives and supports the lower portions of the bags.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.

Multi-layered articles or products comprising layers of filled polymer compositions, methods of making and applications or uses thereof.

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.

A heating block assembly including one or more configurable insulator segments and a heater block having a first surface configured to removably receive the one or more configurable insulator segments, in which each of the one or more configurable insulator segments covers only a portion of the first surface. A method for sealing at least one portion of a package using such a heating block assembly is also disclosed.

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. A method for the production of such an assembly is also described.

A process for forming a container from a blank, the process comprising the steps of: thermally inducing one or more fold lines on at least one surface of a container blank fabricated from a thermal insulation sheet material, wherein the blank comprises: a first panel portion; a second panel portion located adjacent the first panel portion and sharing a first common edge therewith; and a third panel portion located adjacent the second panel portion and sharing a second common edge therewith, the second common edge being substantially parallel to the first common edge, wherein the first panel portion and the third panel portion are each associated with a pair of flap members adapted for folding movement relative to the respective first and third panel portions such that, when assembled, each of the flap members overlies an edge of the second panel portion substantially perpendicular to the first common edge and the second common edge, folding the first panel portion of the container blank along a first fold line, wherein when folded, the first panel portion is substantially perpendicular to the second panel portion of the container blank; folding the third panel portion of the container blank along a second fold line, wherein when folded, the third panel portion is substantially perpendicular to the second panel portion and substantially parallel to the first panel portion; sealing a portion of each of the pair of flap members of the first panel portion to a portion of each of the pair of flap members of the third panel portion to form a side seam joint; and sealing a portion of the first panel portion adjacent the side seam joint and a portion of the third panel portion adjacent the side seam joint to an edge of the second panel portion to form a bottom seam joint.
