A lid member for a food container having a layered structure in which a surface sheet is laid on a composite sheet, said surface sheet including an easily-peelable area that is easily separated from the composite sheet, formed by applying a lubricant between the surface sheet and the composite sheet, said surface sheet including a non-peelable area adjacent to said easily-peelable area; a first slit cut vertical-sectionally through the composite sheet, said first slit defining one or more apertures in said lid to form an opening area in said composite sheet; a second slit in said surface sheet defining a boundary between the easily-peelable area and said non-peelable area of said surface sheet; and said surface sheet being adhered to said composite sheet at said composite sheet opening area over an area that is smaller than said composite sheet opening area.

An easily peelable laminated film includes a laminate of a peelable surface layer (B) having a peeling strength of 5 to 100 g/cm with a base layer (A) containing a thermoplastic resin. The laminated film of the invention provides an easily peelable laminated film excellent in water resistance as a base materialfor, for example, concealing seals and labels for preventing re-pasting. The easily peelable laminated film of the invention requires no specific process to start peeling.

The invention relates to a double-sided pressure-sensitive adhesive sheet for use in fixing a liquid-crystal display module unit to a backlight unit in a liquid-crystal display, the double-sided pressure-sensitive adhesive sheet including at least one heat-peelable pressure-sensitive adhesive layer containing heat-expandable microspheres. According to the double-sided pressure-sensitive adhesive sheet of the invention, since the pressure-sensitive adhesive layer has high adhesiveness and a liquid-crystal display module unit can be tenaciously fixed to a backlight unit with the pressure-sensitive adhesive sheet, excellent adhesion reliability can be attained. Furthermore, since this pressure-sensitive adhesive sheet can be easily made peelable by a heat treatment, it has excellent suitability for reworking.

An applicator die for creating and applying laminarized ribbons of polymeric film to a target surface, such as but not limited to a surface of an automobile body component. In one embodiment, the protective film is an aqueous emulsion of polyvinyl acetate and is used to create a continuous peelable film to protect a surface. In another embodiment, the polymeric is polyvinyl chloride and it is applied to create an anti-chip coating. The applicator die has an internal supply gallery and an outlet slot of complex shape to emit a laminarized ribbon of polymer-based material that allows the material to be applied directly to the target surface without masking. A robot is used to control movement of the die. The die includes temperature control.

A composite container for refrigerated dough products comprises a body ply helically wrapped about an axis to form a tubular body, opposite edges of the helically wrapped body ply being juxtaposed to form a butt joint therebetween. A label is helically wrapped about and adhered to the tubular body, the label comprising an inner layer adhered to the outer surface of the tubular body and an outer layer adhered to a radially outer surface of the inner layer. The inner layer defines a helically extending line of weakness positioned in alignment with the butt joint of the body ply. The outer layer comprises a removable peel strip that is peelable from the inner layer, the peel strip extending helically along the tubular body straddling the line of weakness and butt joint.

It is provided that a polymer film; a preparation method of the polymer film; and a laminated body used the polymer film. The polymer film is suitable for use in producing a laminate body which comprises a support and a polymer film, and is reduced in foreign-matter trapping and which can be used for supplying film devices using conventional apparatuses for glass substrates or silicon substrates. The polymer film coated with the layer of silane coupling agent, which is suitable for producing a laminate that comprises a support and a polymer film, comprises a silane coupling agent layer formed on at least one surface of the polymer film, wherein the silane coupling agent layer has a three-dimensional surface roughness (Sa) of 5.0 nm or less. The method of efficient for producing the polymer film coated with the above layer is the method for producing without using a vacuum.

A method of continuously manufacturing a hermetic plastic zipper wherein the plastic zipper has a readily peelable plastic layer prolonging in a lengthwise direction of the plastic zipper, the readily peelable plastic layer is welded using ultrasonic wave so that the peeling intensity of the welded portion is within a certain range, the method is characterized in that while the engaging portions are brought into a engaged state, the portion of the plastic zipper where the readily peelable plastic layer exists is inserted between an ultrasonic horn and an anvil, and the readily peelable layer is welded by using ultrasonic wave under a condition wherein the distance L between the ultrasonic horn and the anvil is uniformly held at an distance of H≧L≧0.85H wherein H stands for a maximum thickness of the plastic zipper under the engaged state.

An aspect of the present invention is directed to a method for forming a mirror-reflecting film on a waveguide in an optical wiring board, characterized in that a multilayer film, in which a base, a metal layer and an adhesive layer are layered in this order, is used, and the metal layer is transferred and bonded to an inclined face for mirror-reflecting film formation provided on the waveguide, with the adhesive layer of the multilayer film intervening. The present invention provides a method which, when forming a mirror-reflecting film on a waveguide in an optical wiring board, enables inexpensive and easy formation of the mirror-reflecting film, using the smallest quantity of metal possible and employing comparatively simple facilities and techniques.

A method of protecting a glazed frame mounted document from the ravages of light and a fade protector therefore, the protector comprising a transparent UV absorbing polymeric film layer, preferably PET, having a thickness such that the film in use remains substantially flat against the glazing when clamped between the frame and glazing, the film layer being coated on its exposed side in use with a transparent anti-glare hard coating. The glazing is removed from the glazed frame, the fade protector is placed against a surface of the glazing which is then re-assembled in the frame with the fade protector adjacent the eternal surface of the glazing with the anti-glare coating facing outwardly.
