Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 90 ppm/° C. measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 91.8 ppm/° C. and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

Backing for adhesive tape with thermal resistance

Methods and systems of measurement for blown film lines are provided. The sensing system includes a terahertz (THz) sensor positioned adjacent to a film bubble extruded from a blown film die, and a sensor support configured to guide the THz sensor around the circumference of the film bubble to measure its film thickness.

Methods and systems for blown film thickness measurement

Provided are double-coated tapes that include, in the following order: a first pressure-sensitive adhesive layer; a first plastic skin layer; an elastic base layer; a second plastic skin layer; and a second pressure-sensitive adhesive layer. The provided double-coated adhesive tapes can provide a combination of high bond strength, reworkability, and high impact and shock resistance, and can be easily converted using a die cutting process.

Double coated tape

Multilayer films and adhesive tapes that include such films, wherein the multilayer films include plasticized polyvinyl chloride and optionally one or more fillers.

Multilayer films and adhesive tapes

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer and an epoxidized polymer, and an adhesive.

Adhesive tapes

Film constructions and articles including the film constructions, wherein a film construction includes: a backing (or an adhesive layer) having a first major surface and a second major surface; and a release layer disposed on the first major surface of the backing (or adhesive layer), wherein the release layer includes polylactic acid.

Film constructions and articles

Article comprising first and second continuous polymeric layers having at least one polymeric layer exhibiting a random network of strands and connective regions disposed between the first and second continuous polymeric layers. In some embodiments, the article is a tape and polymeric multilayer film having a slip resistant surface.

Article comprising multilayer film

Polymeric multilayer film comprising a layer comprising a first pressure sensitive adhesive and exhibiting a random network of strands and connective regions. The polymeric multilayer films are useful, for example, for tape and graphic articles.

Polymeric multilayer film

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer, and an adhesive.

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer, and an adhesive.
