Masking film stacks, kits composed of said film stacks, adhesive tapes, and covering tapes, and methods for producing said stacks and kits are provided. The masking film stacks comprise masking films having widths and lengths, wherein the masking films are foldable along folding lines, running along the lengths, to form double-ply-folded masking films such that two free longitudinal edges of the double-ply-folded masking films run adjacent to each another and the double-ply masking films are foldable to form stacks and the two longitudinal edges lie on the masking film stacks.

An adhesive composition layer is made from an adhesive composition that includes: a polymer including a copolymer of at least one (meth)acrylate monomer and at least one copolymerizable functional group-containing monomer selected from the group consisting of hydroxyl group-containing copolymerizable monomers, carboxyl group-containing copolymerizable monomers, and nitrogen-containing vinyl monomers; and a curable resin. The adhesive composition layer has a 23° C. initial tensile modulus of elasticity of 0.35 MPa or more and yet 8.00 MPa or less before curing the curable resin in the adhesive composition, and a 23° C. initial tensile modulus of elasticity of 1.00 MPa or more after curing the curable resin in the adhesive composition.

Film stacks are described. In particular, film stacks including a base overlaminate film layer and a removeable skin layer disposed on the base overlaminate film layer are described. Because the removable skin layer develops haze before the point of irreversibly damaging the base overlaminate layer, the film stack can prevent unintentional overstretching when the film stack is stretched together.

The disclosure relates to laminate structures to cover or protect substrates or surfaces. The laminate structure comprises a support layer and a self-sterilizing/antimicrobial layer comprising a sulfonated polymer, capable of killing microbes within minutes and for an extended period of time. The sulfonated polymer has a sufficient degree of sulfonation to kill in less than 120 minutes at least 90% of microbes in contact with the surfaces, and for extended protection of the surfaces for at least one month. The laminate structure is particularly suitable for protecting high-touch surfaces such as door knobs, touch-screens, tables, as well as for use with facemasks, face shields, or as self-sterilizing wraps for surgical instruments and supplies. The laminates can also be used as garments or to cover/protect personnel having contagious diseases, etc., to decrease the transmission of microbes.

Embodiments provide a pressure-sensitive adhesive film having (α) a poly(meth)acrylimide-based resin film layer and (γ) a pressure-sensitive adhesive agent layer in that order from the surface layer side and having a total light transmittance of 80% or higher. The pressure-sensitive adhesive film may further have (δ) a hard coat layer on the surface layer side of the poly(meth)acrylimide-based resin film layer (α). This hard coat layer (δ) may comprise an active energy ray-curable resin composition that contains (A) 100 parts by mass of a polyfunctional (meth)acrylate; (B) 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; (C) 0.05-3 parts by mass of organic titanium; and (D) 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. This active energy ray-curable resin composition may further contain (E) 0.01-7 parts by mass of a water-repelling agent.

A film including a resin layer comprising a structured major surface opposite a second major surface, the structured major surface including a plurality of features; a barrier layer on the structured major surface; and a first adhesive layer on the barrier layer.

A cling foil comprising an outermost adhesive layer comprising a pressure sensitive adhesive, an outermost release layer, the outermost release layer comprising a release material, and a foil layer positioned between the outermost adhesive layer and the outermost release layer.

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.

Embodiments of the present techniques provide an adhesive tape roll that comprises a plurality of detachable segments. The detachable segments comprise a pull tab to help separate a protective liner layer, or backing layer/backing liner, from the adhesive tape at the point of use. Thus, a user may detach a segment from the roll, and then use the pull tab to separate the adhesive tape from the backing liner.

A printable 2-PLY security tape includes a first tape PLY label stock. A first substrate has a printable outer surface as a first outer PLY surface. A first inner PLY surface includes at least one first release area disposed on an inside surface of the first substrate, and at least one first adhesive area is disposed on the inside surface of the first substrate. A second tape PLY security tape includes a second substrate outer surface as a second outer PLY surface. A second inner PLY surface includes at least one second release area disposed on an inner surface of the second substrate, and at least one second adhesive area disposed on the inner surface of the second substrate. The second adhesive area is in contact with the first release area and the first adhesive area in a contact with the second release area, to form a 2-PLY composite tape.
