Abstract: The present invention is directed to a foamable polyolefin composition which is crosslinkable by silane groups, to a crosslinked foam obtained from such a foamable polyolefin composition, and to a process for producing a crosslinked foam based on the foamable polyolefin composition. The foamable polyolefin composition comprises a polyethylene bearing hydrolysable silane groups and comonomer units comprising a polar group selected from the group consisting of acrylic acid, methacrylic acid, acrylates, methacrylates, vinyl esters, and mixtures thereof, a silanol condensation catalyst, a physical blowing agent, and a cell nucleating agent.

Abstract: The present invention relates to a polymer blend and the film of the polymer blend or the film layers of the polymer blend as a surface layer or coating. More particularly, the invention relates to a polymer blend which may be extruded as such or extruded onto one or both sides of packaging film to give a sealing surface(s) which exhibits surprisingly heat sealability suitable for form-fill-and-seal-packaging. The present invention also relates the use of ethylene based plastomer to reduce sealability of films comprising polypropylene.
