摘要:
An adhesive sheet is disclosed including a flexible substrate and an adhesive layer formed on at least one of the main surfaces of the flexible substrate. The adhesive sheet further includes a plurality of microscopic holes connecting the opposing surfaces of the sheet and being generally perpendicular to them. Such adhesive sheet is permeable by air and allows good bubble escapability when the sheet is applied to an article. Sufficient permeability of the sheet to air is achieved with microscopic size holes installed in modest areal densities, hence the appearance and functionality of the film surface are not significantly adversely impacted. One intended use of the subject invention is for tinting films used to reduce light transmission in windows for use in buildings and automobiles. In this application visual appearance of the film is paramount. Another intended application of the subject invention is for antireflective film which is applied to electronic computer displays (flat panel, cathode ray tube) to reduce unwanted ambient light reflection and to improve contrast.
摘要:
Disclosed is a label for in-mold forming comprising a thermoplastic resin film base layer and a heat-seal resin layer, wherein a surface of the heat-seal resin layer has a centerline average roughness of 0.5 to 5 micrometers and the label has an air permeability of 10 to 20,000 seconds. When in-mold forming is conducted with the label of the present invention, labeled molded resin articles of various shapes can be manufactured while effectively inhibiting blistering.

摘要:
A laminating blow molding method for making a hollow article includes the steps of forming 1 to 500 fine, holes per an area of 100 cm.sup.2 in a resin sheet by punching to thereby form projections as burrs on one side of the resin sheet, the diameter of the holes being between 0.1 mm and 1 mm; disposing the resin sheet between an outer surface of a parison extruded from a die and a mold so that the one side with the projections faces a cavity face of the mold; closing the mold so that the resin sheet is held between the cavity face of the mold and the outer surface of the parison; and heating the mold to a temperature exceeding a softening temperature of the resin sheet and simultaneously blowing the parison to perform blow molding. Thereafter, the mold is cooled and a molded article is taken out. In the method, the molded article with smooth outer surface can be obtained.
摘要:
Disclosed is a label comprising a substrate film, or a substrate film and an intermediate film, wherein either or both of the substrate film and the intermediate film have through-holes, and a method for preparing the same. The method for preparing the label causes no generation of defects, and shows an excellent production rate and work efficiency. The label has no possibility of forgery, and shows clear marking characteristics. In addition, the label has a simple structure and excellent printability and cost efficiency, causes no degradation of the quality with time, shows high chemical resistance and heat resistance, is free from various contaminants during use, and is provided with low initial adhesion but high permanent adhesion.

摘要:
The present invention relates to an in-mold label having a roughened inside surface to engage an article being molded in the mold. This roughened inside surface reduces air-entrapped blistering formed during molding, the air-entrapped blisters being between the label and the molded article. Preferably the label includes a plurality of perforations therein. To create the roughened inside surface at the time of perforating the label, the perforations are made by needles passing from the outside or exterior surface of the label through the inside surface thereby creating burrs on the inside surface; the inside surface being the surface which will engage the article to be molded. The label also preferably, in addition to the plurality of perforations and roughened inside surface, includes adhesive in a pattern on the inside surface.
摘要:
The specification discloses an in-mold label (IML) having an improved holographic image. The label includes a base ply and a top ply laminated together. The base ply is an in-mold label material, and the top decorative ply is a different material that is smoother than the base ply material. A holographic material is on the top surface of the top ply, and a holographic image in formed in the holographic material to provide a bright, aesthetically attractive label.

摘要:
An improved method for preparing a molded plastic container with embedded label in which the label contains one or more perforations to reduce blistering during the blow molding process. In a preferred embodiment, the perforations are larger on one side of the label than the other to facilitate the release of gases that otherwise would be trapped behind the label.
