0001 The proposed product relates to the field of manufacturing packaging for primarily liquid, fatty, and frozen food products or for products that contain or release fats and moisture. The present packaging, having an overlapping seam with a sealed end face, is made of a shape-giving material that consists of a base material and a protective layer applied on one side of said base material. The protective layer is elongated relative to the base material, and at the place where the shape-giving material is joined in an overlapping fashion to form a seam, the elongated protective layer is connected on the inner side of the packaging to the adjoining layer of shape-giving material without the protective layer coming into contact with the end face surface of the shape-giving material, to protect an end face without thickening the material at an overlap point and without the overlap point being excessively rigid, as well as without using an additional protective polymer tape or an expensive base material having hydrophobic properties.

0000 Provided herein is a moisture barrier film for packaging, such as tobacco or cigarette packaging. The film comprises polylactic acid (“PLA”) that is both biodegradable and transparent. The film includes multiple layers of PLA, with a base layer having a relatively high melting point compared to two outer layers, which have a relatively low melting point. The outer layers provide heat sealing capabilities to the film. The film is coated with a metal oxide layer comprised of aluminum oxide, titanium oxide, and/or aluminum-titanium oxide using an atomic layer deposition (“ALD”) coating method. The ALD coating to the PLA film results in a moisture transmission rate of less than 4 g/m2/day after the film has been subjected to creasing, which induces cracking of the ALD metal oxide layer.
