20220134718 · 2022-05-05 ·

An adhesive-free laminate and a process for producing such a laminate are described herein. The process includes printing an ink on the surface of a first film, exposure of the printed film to UV radiation such that the ink is at least partially cured, attaching the first film to a second film such that the ink is between the first and second film, and exposing the combination of the first film, the ink and the second film to a second UV radiation. It has been found that this process can produce a unique laminate, without the presence of an adhesive.

MAINTAINING SUITABLE SEALABILITY AND HOT TACK STRENGTHS OF ACRYLIC- AND ACETATE-BASED COATINGS WHEN USING BASE FILMS CONTAINING HCR TO IMPROVE THEIR WATER-VAPOR BARRIERS

In one embodiment, the disclosure provides a film, which may be oriented, cast, or blown, that includes a core layer having a first side and a second side, wherein the core layer comprises hydrocarbon resin and polypropylene. Further, the film may include a first tie layer on the first side, wherein the first tie layer consists of polypropylene and about 5% or less of additives with exclusion of hydrocarbon resin (“HCR”), wherein the polypropylene is standard-crystalline polypropylene, high-crystalline polypropylene, or a mixture thereof, but preferably, it is a majority of high-crystalline polypropylene. Further still, the film may include a first skin layer on the first tie layer, and, also a coating on the first skin layer, wherein the coating comprises acrylic or acetate polymers or combinations thereof. The film maintains a minimum seal temperature of 300 g in.sup.−1 seal strength as compared to the film without any HCR.

Clear film for tapes and labels

A multilayer film for use in adhesive tape or adhesive label applications comprising a core layer and skin layers on each side of the core layer. The core layer comprises a polypropylene mini-random homopolymer, wherein the mini-random homopolymer comprises polypropylene, up to 2 wt % ethylene components, and a acid neutralizer in a concentration up to 5000 ppm calcium. The skin layers each comprise a) at least about 95 wt % of a polypropylene mini-random homopolymer comprising polypropylene, up to 2 wt % ethylene components, and an acid neutralizer in a concentration up to about 5000 ppm, and b) an anti-block agent in a concentration up to about 1 wt %, wherein the anti-block agent comprises at least 95 wt % homopolymer of polypropylene and 1 to 5 wt % of silica having a particle size between about 1 to 3 μm.

Clear hot melt adhesives
11312886 · 2022-04-26 · ·

Hot melt adhesives comprising (i) styrene butadiene copolymer, (ii) olefin block copolymer (OBC), and (iii) water white hydrogenated hydrocarbon resin are described. The adhesives exhibit high optical clarity and are relatively clear over a wide range of temperatures. The adhesives also exhibit good adhesion at cold temperatures. Also described are laminates of the adhesive with polymeric films, such as adhesive labels that can be used in labeling containers. In addition, various goods such as containers labeled using the adhesives are described.

Self-Laminating Rotating Cable Marker with Breakaway Portion

A self-laminating rotating cable marker label is constructed of a transparent film having a first adhesive area, an adhesive-free smooth area, and a second adhesive area. A print-on area forms one side of the transparent film, the print-on area adapted to receive indicia identifying the cable about which the marker label is applied. A perforation extends across the transparent film providing a line of separation of the transparent film. When wrapped around a cable, the second adhesive area overlies the print-on area such that the cable identifying indicia is visible through the transparent second adhesive area. As the transparent film is wrapped around the cable, the first adhesive area adheres to the cable. The remainder of the transparent film is rotated, breaking the perforation, whereby the smooth area of the film in contact with the cable provides smooth rotation of the label around the cable.
