The aim is to provide an adhesive tape that effectively protects an electronic construction from permeants, especially water, and that at the same time has good gap-filling qualities. To solve this problem an adhesive tape is proposed that has in the following order:—a carrier layer without barrier effect at least towards water and with a WVTR of at least 1 g/(m.sup.2*d) (38° C., 90% relative humidity, 50 μm layer thickness); —a layer comprising at least one getter material capable of sorbing at least water; —a water barrier ply; and—a layer of pressure-sensitive adhesive, where the carrier layer bears an outward-facing release layer and/or the layer of pressure-sensitive adhesive is lined with a release liner which has a release layer lying on the layer of pressure-sensitive adhesive.

A roll and a method for producing a roll which are capable of effectively preventing tunneling are provided. A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer, a substrate layer, an adhesive layer, and a release liner, in this order, in a laminating direction. The process film is formed from at least one member selected from polyethylene terephthalate (PET), polyolefins, and polyvinyl chloride (PVC). The surface coat layer is formed from a fluorine resin. The release liner is formed from polyethylene terephthalate (PET). The core is formed from an acrylonitrile-butadiene-styrene copolymer resin (ABS) or polypropylene (PP).

A protective garment is disclosed that is reusable and can be relaundered over 70 times. The garment is made from a single layer barrier fabric. Any seams on the protective fabric are covered with a seam tape. The seam tape can include an adhesive layer, a cover layer, and an optional film layer positioned between the cover layer and the adhesive layer. The adhesive layer can be a crosslinkable polyester polymer.

The present disclosure relates to an acrylic pressure sensitive adhesive tape including a moisture barrier layer in a release layer, and to an acrylic pressure sensitive adhesive tape, which can enhance adhesion by the moisture barrier layer preventing reduction of adhesion of an acrylic adhesive layer caused by moisture.
