A hand-tearable masking tape, comprising a plastic backing with a low adhesion backsize on the first major side of the backing and a pressure-sensitive adhesive on the second major side of the backing; wherein the second major side of the backing comprises a microstructured hand-tear pattern and wherein the low adhesion backsize comprises the reaction product of a mercapto-functional silicone macromer.

Hand-tearable masking tape with silicone-containing low adhesion backsize

Tape backings with a first major side and an oppositely-facing second major side, wherein the first major side includes coextensive, intersecting microstructured paint-retention and hand-tear patterns; and, tapes including such backings, and methods of making and using such tapes and tape backings.

Microstructured tape comprising coextensive, intersecting paint-retention and hand-tear patterns

A hand-tearable masking tape with a primary microstructured hand-tear pattern and at least one secondary hand-tear pattern oriented so that the tape exhibits multi-directional tear.

Masking tape with multi-directional hand tear

Herein is disclosed a plastic tape, comprising a backing with a first major side comprising a microstructured paint-retention pattern and a second major side that may comprise a microstructured hand-tear pattern and with a pressure-sensitive adhesive layer disposed on second major side of the backing; wherein the backing, the microstructured paint-retention pattern, and the microstructured hand-tear pattern (if present) all constitute a monolithic plastic unit.

Microstructured tape

Herein is disclosed a device and method for attaching a tab to an elongate length of double-sided adhesive tape, the tab protruding beyond a terminal end of the elongate length of tape and being attached to both surfaces of the adhesive tape.

Device for applying a protruding tab to double-sided adhesive tape, and method of using

A stretch releasing adhesive tape with an improved pull tab is disclosed. Methods are provided by which a single tab film may be adhered to an elongated strip of stretch releasing adhesive tape to form a manually engageable pull tab at a selected location. Such a pull tab may be foldable so as to comprise an unobtrusive visual appearance and may also be extendable so that the pull tab may be grasped to activate the stretch release.

Removable adhesive tape and pull tab, and method of forming

Kits are described wherefrom a single tab film may be adhered to an elongated strip of stretch releasing adhesive tape to form a manually engageable pull tab at a selected location. Such a pull tab may be foldable so as to comprise an unobtrusive visual appearance, and may also be extendable so that the pull tab may be grasped to activate the stretch release.

Removable adhesive tape and pull tab film, and kits

A stretch releasing adhesive tape is disclosed comprising a pull tab comprising a single tab film which is adhered to both adhesive surfaces of the stretch releasing adhesive tape. The pull tab is foldable so as to comprise an unobtrusive visual appearance, and may also be extendable so that the pull tab may be grasped to activate the stretch release.

Removable adhesive tape with foldable pull tab

An inflatable packaging system comprised of an inflation channel that feeds a plurality of inflatable cells prevents buckling of the inflation header as the inflatable cells inflate by relieving stress along a seal line that separates the inflation header from the inflatable cells.

Inflatable packaging system

A multi-chambered inflatable member formed by connecting the perimeters of two polymeric film layers includes a seal line spaced from the perimeter that interconnects the two film layers to form a perimeter inflatable channel along a portion of the perimeter. A plurality of inflatable cells extend between opposing portions of the inflatable channel and are in communication with one of the opposing portions of the inflatable channel. A check valve communicates with the inflatable channel to inflate the inflatable member. Articles being shipped or stored in a container can be placed between two or more inflatable members, the perimeter inflatable channels of which provide perimeter protection between the article and the container.

Low profile inflatable package protection system

A method of stretching films in which all or a portion of the width of the film is cooled during or just after stretching so as to improve the uniformity of the film. The includes stretching a polymeric film in a tenter that grasps the film with a plurality of clips along the opposing edges of the film and propels the clips to thereby stretch the film. The tenter includes driven clips and idler clips, with at least one idler clip between respective pairs of driven clips. The cooling is done so as to improve the uniformity of the clip spacing relative to the spacing obtained at otherwise identical process conditions without such cooling.

Method of stretching film

A multi-layered biaxially oriented film comprising at least one primary layer and at least one secondary layer, wherein the primary layer comprises a propylene copolymer having a first melting point and the secondary layer comprises a polypropylene homopolymer or copolymer having a second melting point, such that the second melting point is greater than the first melting point and the multi-layered construction is biaxially stretched. The multi-layered film further includes a surface finishing layer, to provide a writable multi-layered film. This stretched film exhibits a refractive index in the machine direction (MD) that is greater than the refractive index measured in the transverse direction (TD).

Oriented multilayer polyolefin films

Adhesive tape backing

An article that is capable of accepting and anchoring printed indicia and yet, maintains good release properties. The article of the present invention is coated with a release agent on a substrate such as paper. Release coatings receptive to toner particles emitted by electrophotoconductive devices comprise a polymer having at least one vinyl polymeric segment having a T.sub.g between -10.degree. C. and 65.degree. C. and at least one siloxane polymeric segment.
