Abstract: A laminated tube container has the body comprising a sheet material comprising a substrate, a silicon oxide deposited layer, a heat buffer layer and an extruded coating layer of a thermoadhesive resin which are successively formed in a laminate. The heat buffer layer prevents cracks from being produced in the silicon oxide deposited layer by the heat coming when the extruded coating layer of a thermoadhesive resin is laminated. The heat buffer layer is preferably formed by dry lamination or non-solvent lamination which requires no heating. An anchor coat layer may optionally be provided between the heat buffer layer and the extruded coating layer of a thermoadhesive resin so that the adhesion strength between these layers can be improved.

The preferred ionomer is surlyn resin and the preferred cross-linkable resin is melamine-formaldehyde.

Abstract: A film composite has a thin flexible decorative backing bearing a layer of adhesive which affords good repositionability and yet can become permanently bonded to highly plasticized substrates such as vinyl films containing migratable monomeric plasticizers. Such substrates include wall coverings and vinyl coated fabrics. The adhesive is a blend of an acrylic latex adhesive and a heat-activatable urethane latex adhesive, which blend has been coated onto the backing from an aqueous emulsion. Useful backings include vinyl, polyurethane, and polyolefin films.

Abstract: A label comprising a polyethylene film in which the degree of crosslinking inwardly decreases across the thickness of the film and on one side of which printing is performed, and an adhesive layer further formed thereon. The label is good in clarity, is possible to perform back surface printing, can provide an integral feeling and a high-class feeling as if curved-surface printing is performed on a cylindrical container itself, is sufficient in rigidity and strength and therefore is possible to be thinly formed, is resistant to water wetting and contamination, is unnecessary to be stripped in recovering and recycling a polyethylene bottle when the label is stuck thereon, can be stuck on the bottle concurrently with blow molding of the bottle printed, and is therefore suitable for use as a label for in-molding.

Abstract: Reflective tape for pinstriping of automobiles or other vehicles. The tape has strips of retroreflective material sandwiched between a bottom release liner of polyethylene coated paper and a clear top release liner having an adhesive undersurface for retaining the tape composite intact with the strips parallel one another prior to and during application to a vehicle. The retroreflective material is highly visible at night for safety. The strips include pressure-sensitive adhesive. When the tape is applied to a vehicle, thin pinstripes of retroreflective material are seen. The material may be colored to contrast with the color of the vehicle paint, which is visible on either side of the tape and also through the open middle section between the pinstripes of retroreflective material. The strips are applied by peeling away the bottom liner as the top liner and strips are applied to a surface; thereafter, the top release liner is peeled away leaving only the two retroreflective material strips on the surface.

Abstract: A web of packaging material includes a pair of flaps folded onto a backing sheet and laterally heat sealed at uniform positions along the web, forming pairs of bags having laterally opposed openings. The web is perforated at the heat seals to allow ease of separation of the pairs of bags from the web, while longitudinal perforations allow for the separation of the bags of each pair from each other. Releasable adhesive strips are provided on closure flaps to allow closure of the openings of the separated bags. The bags are filled by draping them over a carrier bar, passing them under a blower and filler, and subsequently separating the bag pairs from each other and sealing them.

Abstract: A method of forming a transferable pattern or image of an inorganic film by coating an embossed substrate with an inorganic layer, that may comprise one or more films, over both recessed and raised surface portions, adhesively laminating a transfer substrate to the inorganic layer coating the raised surface portions of the embossed substrate and separating the embossed substrate and the transfer substrate. The adhesive is selected such that the bond between the transfer substrate and the inorganic film on the raised surface portions is greater than the bond between the inorganic layer on the raised surface portions and the embossed substrate.The embossed substrate resulting after removal of the inorganic layer coating the raised surface portions may be modified to include additional inorganic layers over the recessed surface portions by tinning or electroplating methods such that this thickened inorganic layer may also be transferred from the embossed substrate to a transfer substrate a set forth above.

Abstract: A system is provided for adhesively attaching a first member to a generally planar portion of a second member. The system includes an attachment clip having a first, generally planar portion and a second portion remote from the first portion adapted for attachment to the first member. A generally planar base is sandwiched between the planar portion of the attachment clip and the planar portion of the second member. An adhesive is located between the base and the planar portion of the second member. A weld is provided between the base and the planar portion of the attachment clip. Therefore, "peel" stresses are eliminated between the base and the planar portion of the second member, as the weld develops a tensile load between the base and the planar portion of the attachment clip.
