摘要:
A diaper construction (10) is provided with an external porous reinforcement strip (11) at the front part of the outside of the diaper (10), which strip (11) provides reinforcement against an adhesive fastening tab (4) and provides an oil-contamination tolerant adhesion surface.

摘要:
A pressure-sensitive adhesive closure system for a disposable diaper (20), or the like, in which a pressure-sensitive adhesive fastening tab (4) releasably attaches to a non-blocking thin diaper backsheet (2) which has been treated to raise the surface energy and pattern printed, preferably in a polar solvent, in a discrete area with a release material. The release material prevents the backsheet from blocking in roll form and allows the pressure-sensitive adhesive fastening tab to be removed from the backsheet without destruction of the backsheet.
摘要:
A non-yellowing pressure-sensitive adhesive tape with a polyolefin film layer and a fibrous web layer. A propylene film layer has an an antioxidant package of: (i) 0.004 to 0.04 weight percent of Irganox TM 1010; (ii) 0.03 to 0.2 weight percent of a solid phosphite antioxidant; (iii) 0.05 to 0.4 weight percent of a thioester; and (iv) 0.05 to 0.4 weight percent of an inorganic acid scavenger; The tackified synthetic rubber pressure-sensitive adhesive layer comprises 100 parts of a polystyrene-polydiene block copolymer, and 20 to 300 parts of a compatible tackifying agent and an antioxidant package, based on 100 parts of the polystyrene-polydiene block copolymer, comprising: (i) 0.1 to 0.6 parts Irganox TM 1010; (ii) 0.1 to 0.6 parts Irganox TM 565; (iii) 0.0 to 0.6 parts of a phosphite antioxidant.
摘要:
A novel 2-substituted butadiene block copolymer is provided which provides adhesives having superior adhesion and tolerance to oil contaminated surfaces. The elastomeric block has a glass transition temperature of less than about minus 65 DEG C, with the 2 substituent being an alkyl group.
摘要:
A hot melt coatable pressure-sensitive adhesive is provided showing high levels of adhesion to low surface energy films and nonwovens. The adhesive elastomeric phase comprises from 78 to 98 parts by weight of a diblock A-B type block copolymer with an elastomeric block of 1,3-polybutadiene with 2 to 22 parts by weight of multiblock A-B type block copolymer. The tackifying material comprises 140 parts or less of a solid tackifying resin and a liquid tackifier to provide an adhesive having a composite midblock glass transition temperature of less than -10 DEG C.
