A method of making an optical body an optical body is disclosed. The method includes coextruding a first skin layer and a first strippable skin layer on a first side of an optical layer. The first skin layer is disposed between the optical layer and the first strippable skin layer. The first skin layer includes a mixture of a polyacrylate and a second polymer which may or may not be miscible in the polyacrylate. The second polymer may be an anti-static polymer.

This disclosure discloses an adhesive tape having a dimension in a thickness direction, comprising a tape base layer, an adhesive layer, a separation material, and a separation layer. The adhesive layer is disposed on one side of the tape base layer in the thickness direction and is including a predetermined adhesive. The separation material separably adheres to the adhesive layer, and is provided on the one side of the adhesive layer in the thickness direction. The separation layer is provided on the other side of the tape base layer in the thickness direction and is including an olefin resin separating agent or an acrylic resin separating agent having a long-chain alkyl group.

A resealable package assembly is described. The package assembly includes a selectively positionable flap that covers an aperture or enables access through the aperture into the package. The flap and package include provisions for releasably engaging the flap to the package to seal the interior of the package. Provisions for grasping the tab and indicating whether tampering has occurred are also described.

The invention relates to the technical field of adhesive tape and discloses an use of a high-performance ultra-thin double-sided adhesive tape in wireless charging, including a polyester film substrate, a high-performance adhesive coating coated on both sides of the polyester film, wherein the high-performance adhesive coating is composed of the following parts by weight of each component uniformly mixed: 100-140 parts by weight of high-performance acrylic pressure sensitive adhesive, 15-20 parts by weight of curing agent, and 130-160 parts by weight of ethyl acetate. The thickness of the adhesive tape is 0.003-0.010 mm, with a good adhesion and a mechanical strength.

A method is presented for producing an optically transmissive layered structure for use as a display protector for electronic devices. The method comprises printing an ink pattern on a base layer, where said base layer is substantially optically transparent, and the base layer and ink are configured so that the ink reflects light with high incidence angle and transmits light with low incidence angle, when in use, thus displaying the pattern in the absence of light with high intensity and low incidence angle, the pattern becoming substantially undetectable otherwise.

A patch including a polyurethane film, a first adhesive layer provided on one surface of the polyurethane film, and a cover tape provided on the other surface of the polyurethane film, wherein the cover tape includes a base material and a second adhesive layer provided on one surface of the base material and an adhesive surface of the second adhesive layer is laminated on the other surface-side of the polyurethane film, and the first adhesive layer contains an adhesive and an organic liquid component.

The present disclosure relates to a pressure sensitive adhesive composition, comprising: a) a first (meth)acrylate copolymer comprising from 0.1 to 12 wt % of (meth)acrylic acid monomer units, based on the weight of the first (meth)acrylate copolymer; and b) a second (meth)acrylate copolymer comprising from 15 to 40 wt % of (meth)acrylic acid monomer units, based on the weight of the second (meth)acrylate copolymer. According to another aspect, the present disclosure is directed to a multilayer pressure sensitive adhesive assembly comprising a pressure sensitive adhesive composition as described above in the form of a first pressure sensitive adhesive polymeric layer, and which further comprises a second pressure sensitive adhesive layer adjacent to the first pressure sensitive adhesive polymeric layer. In another aspect, the present disclosure is directed to a method of manufacturing a pressure sensitive adhesive composition as described above and to uses thereof.

A substrate-free adhesive tape which is easily applied to a continuous process due to an excellent adhesive strength and a short fracture distance is provided. An adhesive composition for making the substrate-free adhesive tape is also provided.

Improvements in a graffiti covering skin are disclosed the covering skin is formed from multiple layers of transparent or filtering layers that can be individually removed to provide a new layer without graffiti or damage. Each layer of the skin provides different functions to provide a material that covers existing graffiti and creates a new surface that reduces or repels future graffiti from being placed on the original host surface. One of the layers can be a visual pattern layer that provides the desired appearance of a hard surface of stainless steel, mirror, wood, color, marble, granite or light filtering. This layer provides a structural rigidity that maintains dimensional stability. The skin is backed with a removable adhesive that is removed from the host surface without leaving a residue. Each skin is measured and cut to the desired size before placement in a host surface.

A resealable package assembly is described. The package assembly includes a selectively positionable flap that covers an aperture or enables access through the aperture into the package. The flap and package include provisions for releasably engaging the flap to the package to seal the interior of the package. Provisions for grasping the tab and indicating whether tampering has occurred are also described.
