A breathable thermoplastic polymer film may be produced and adapted for use as a breathable diaper backsheet. The film may include a blend of LLDPE, mLLDPE and calcium carbonate, and may have improved tear strength and melt strength such that instances of tears or break offs during the machine direction orientation portion of the production process are significantly reduced or eliminated. In addition, the film may have sufficient tear strength to permit omission of CDI processing needed to strengthen weaker prior art films. In this regard, undesired streaking of colors or printed aspects of the film may be reduced or avoided completely.

Breathable diaper backsheet

The present invention provides a multilayer sealable film having a sealable outer layer, a first heat resistant layer, a core layer, and a second heat resistant layer. In a preferred embodiment of the present invention, the core layer is positioned between the two heat resistant layers. The sealable layer is positioned such that one of the heat resistant layers is located between the seal layer and the core layers.
