A multilayer adhesive film comprising surface adhesive layers, an internal Controlled Bond Layer ('CBL') comprising a propylene-based polymer strippably adhered to an adjacent layer; an internal Strong Bond Layer ('SBL') different than the CBL having a facial surface in adhering contact to the CBL and; optionally, one or more different internal Filler Layer(s) located between the SBL and the adhesive surface layer on the side of the SBL opposite to the adhered CBL. In preferred embodiments the adhesive comprises an ethylene/ethylenically unsaturated carboxylic acid copolymer. The adhesive films are used in cable shielding structures.

Controlled peel laminate adhesive films

A multilayer film comprises at least 3 layers including a first outer layer, a second outer layer and between the first and second outer layers at least one core layer. The first and second outer layers each comprise at least 75 weight percent of (a) at least one high impact polystyrene component. The core layer(s) comprises(s) (b) at least one styrene block copolymer that is present at a concentration of at least about 2 weight percent of the polymers in the film; and polymers (a), (b) and (c) at least one general purpose polystyrene having a Mw of more than 200,000 and 350,000 or less and that is present at a concentration of at least about 10 wt. % and up to at most about 50 wt. % of the polymers in the composition account for 100 percent by weight of the polymers in the polymer composition excluding polymeric additives.

Multilayer coextruded shrink labels of oriented polystyrene film containing small rubber particles and low rubber particle gel content and block copolymers

This invention comprises a film useful as an adhesive, a composition useful to make the film, and a laminate comprising the film contiguous with at least one metal substrate, at least one foam substrate or combination thereof. The composition comprises (a) at least one anhydride grafted olefin polymer, (b) at least one high density polyethylene, and (c) at least one elastomer which preferably has a tensile elongation at break of at least about 585%, a density of at most about 0.900 g/cmor a combination thereof. The anhydride grafted olefin polymer or combination thereof is preferably present in an amount of from about 20 to about 40 weight percent, the high density polyethylene or combination thereof is preferably present in an amount of from about 40 to about 60 weight percent, and the elastomer or combination thereof is preferably present in an amount of from about 17 to about 30 weight percent. Each anhydride grafted olefin polymer is independently most preferably a maleic anhydride grafted high density polyethylene. The high density polyethylene preferably has a melt index at most about 30 dg/min. The elastomer is preferably a substantially linear ethylene polymer or olefin block copolymer.
