ABSTRACT:
A polyolefinic multilayer film comprises at least three layers BIT, wherein B is a polyolefinic base layer, I is an intermediate layer, and T is a top layer applied to the intermediate layer I. The intermediate layer I comprises at least 75% by weight, based on the weight of the intermediate layer I, of heat sealable polyolefins. The top layer T comprises at least 75% by weight, based on the weight of the top layer T, of heat sealable polyolefins. The minimum sealing temperature of the polyolefin of top layer T is at least 100.degree. C. and is greater than the minimum sealing temperature of the polyolefin of the intermediate layer I. The thickness of the top layer T is less than 0.4 .mu.m.
