| description | The invention provides constructions which may be useful as stretch-release tapes, and the constructions comprise: a first pressure sensitive adhesive (PSA) layer; a support layer; and a second pressure sensitive adhesive (PSA) layer; wherein the support layer comprises: 55-95 wt% of an olefinic copolymer of ethylene and alpha-olefin(s) comprising 3-12 carbons; and 5-45 wt% of a first tackifier. Alternately, the support layer comprises: 55-100 wt% of an olefinic copolymer of ethylene and alpha-octene; and 0-45 wt% of a first tackifier. Alternately, the support layer comprises a first tackifier; the first PSA layer comprises a second tackifier; and the second PSA layer comprises a third tackifier; where the first, second, and third tackifiers are the same tackifier. In some embodiments, first and second PSA layers comprise 30-70 wt% of a styrenic copolymer and 30-70 wt% of a tackifier.
本发明提供了可用作拉伸剥离带的构造，所述构造包括：第一压敏粘合剂(PSA)层；支撑层；和第二压敏粘合剂(PSA)层；其中所述支撑层包含：55-95重量％的乙烯与包括3-12个碳的α-烯烃的烯烃共聚物；和5-45重量％的第一增粘剂。另选地，所述支撑层包含 |
