A composite vent has an elongated rectangular central panel with two narrower longitudinal rectangular side panels hingeably attached or detachably connected thereto, such that the side panels form a range of obtuse angles with the central panel. The reverse sides of the side panels contain one or more adhesive strips, such that the vent can be securely attached across the corner or side of a trash receptacle regardless of the size or shape of the receptacle or the angle at which the side walls of the receptacle meet to form a corner. The composite vent creates a vertical airway along the corner of side of the trash receptacle, such that air can enter at the top of the panel and flow down the sides of the receptacle and into the bottom below the liner bag. To prevent obstruction of the airway by the liner, the vent panel can be perforated at intervals along its length, and/or it contain a vent opening at its lower edge.

To provide an article support structure used when attaching an article to an adherend with a stretch- releas'able adhesive tape in which components and the like do not fly off when releasing the adhesive tape from the adherend, the double -sided adhesive tape does not tear, and damage to high- sensitivity adherends can be effectively suppressed. An article support structure comprises a base plate which can be removably attached to an article, and a double -sided adhesive tape intervening between the base plate and an adherend, and having a stretchable base material and an adhesive layer. The base plate has a project ion- shaped gripping member, and at least one pair of spacer members disposed on both sides thereof which can form a gap between the surface of the adherend and the bottom surface of the base plate, and is configured so that the position of the gripping member and the position of the spacer members at least partly overlap in the length direction of the double-sided adhesive tape.

The invention relates to a double-side-coated release film. The double-side-coated release film is characterized by comprising a base film layer; two release layers are respectively arranged at the two sides of the base film layer; the release layers are respectively formed by coating a release agent; the release agent is prepared from the following components in parts by mass: 10-20 parts of vinyl organic silicon resin, 15-30 parts of polyethylene glycol terephthalate, 5-10 parts of polyethylene glycol, 1-6 parts of nano silicon dioxide, 3-10 parts of a conductive polymer, 0.1-0.6 part of a low-surface tension auxiliary agent, 1-3.5 parts of a toughening agent, 0.5-1.5 parts of a defoaming agent and 18-30 parts of a solvent. The double-side-coated release film does not produce adhesion when being separated from an adhesion belt or adhesive tape which is in contact with the release film, thus being good in separation effect; furthermore, the double-side-coated release film contains the conductive polymer, thus having very strong antistatic ability; therefore, the double-side-coated release film is wide in application scope.

Provided is a novel pressure-sensitive adhesive tape having a moderately weak adhesion during a time period from a production process (during its production) to the time of the accomplishment of the product as a result of the completion of the production (immediately after the production). Accordingly, the peeling failure, or the like, resulting from strong adherence of a pressure-sensitive adhesive layer to a roll or the like at the time of the production can be sufficiently suppressed. As a result, stable product supply can be performed. In addition, even after the lapse of about a half day from immediately after the production, the pressure-sensitive adhesive tape can be easily rewound. On the other hand, the pressure-sensitive adhesive tape can express a sufficiently strong adhesion for an adherend after the lapse of a predetermined time from the production (e.g., at the time of its use). The pressure-sensitive adhesive tape of the present invention includes at least three layers including: a base material layer (A); a first pressure-sensitive adhesive layer (B1); and a second pressure-sensitive adhesive layer (B2) in the stated order, in which: the base material layer (A) contains a thermoplastic resin; the first pressure-sensitive adhesive layer (B1) contains a tackifier at a content of 12 wt % or more; the second pressure-sensitive adhesive layer (B2) contains a tackifier at a content of 10 wt % or less; and the second pressure-sensitive adhesive layer (B2) has a thickness of 10 μm or more.

The invention relates to a reflecting release film, which is characterized by comprising a base film layer, wherein a release layer is arranged on the base film layer; the release layer is formed by coating a release agent; the release agent is prepared from the following ingredients in parts by mass: 20 to 35 parts of reflecting powder, 10 to 40 parts of vinyl organic silicon resin, 5 to 18 parts of butyl acrylate, 2 to 6 parts of titanium dioxide, 0.1 to 3 parts of antioxidant, 1 to 5 parts of coupling agents, 0.5 to 1.5 parts of defoaming agents and 15 to 30 parts of solvents. The reflecting release film has the advantages that adhesion cannot be generated when the obtained release film is separated from a contact adhesion belt or bonding belt; reflecting powder glass microbeads are added, so that the recognition degree of the release film is enhanced at night or in dark lamp light environment; the processing and the use of the release film are convenient.
