Abstract
A peelable adhesive article capable of adhering to a substrate wherein subsequent removal of the adhesive does not damage the substrate, and methods of making and using said peelable adhesive article. The adhesive articles comprise a peelable adhesive adjacent to a major surface of a backing, wherein the backing has a modulus of elasticity and/or modulus of secant between 100 to 18,000 psi as measured by ASTM D638-14 and/or ASTM D412-06a. The backing may be a multilayer backing comprising a core layer and at least one skin layer in a ratio of 2:1 to 100:1.
Claims18
An adhesive article, comprising:
- a multilayer backing comprising:
- a core layer comprising at least one of an elastomeric material, an elastomeric polymer, SEBS, SEPS, SIS, SBS, polyurethane, ethyl vinylacetate (EVA), ethyl methyl acrylate (EMA) ultra low linear density polyethylene (ULLDPE), hydrogenated polypropylene, and combinations or blends thereof;
- a first skin layer comprising at least one of polypropylene, polyethylene, high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), a polyurethane, EVA, EMA, an adhesive, and combinations or blends thereof;
- and
- a peelable adhesive adjacent to a major surface of the multilayer backing;
- wherein the backing has a core to skin ratio of between about 2:1 and about 100:1;
- and
- wherein the backing has a modulus of elasticity and/or a modulus of secant of between about 100 psi and about 18,000 psi as determined by at least one of ASTM D638-14 and ASTM D412-06a.
