Abstract
Sealable multilayer polyolefin film containing hollow particles, process for its production and its use An oriented polyolefin film is described. It contains at least one polyolefinic base layer and one polyolefinic sealable top layer. The top layer contains hollow particles which comprise essentially a polymer which is incompatible with the polyolefin of the top layer. A process for the production of the film and its use are also described.
