Resumen de: US2020299024A1
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.

The invention provides a cigarette provided with a cavity type vessel section and capable of being not burned after being heated. The cigarette includes a tobacco section, the cavity type vessel section, a near-lip section and an outer wrapping material, wherein the tobacco section, the cavity type vessel section and the near-lip section are coaxially and sequentially connected, and the outer wrapping material limits the tobacco section, the cavity type vessel section and the near-lip section. The tobacco section includes smoke formation materials, and the core material of the tobacco sectionis wrapped by aluminum foil composite forming paper or anti-oil forming paper. According to the cigarette provided with the cavity type vessel section and capable of being not burned after being heated, materials of the multiple-cavity type vessel section can make the cigarette possess good cooling performance, and when users have a smoke, no burning feeling exits. Moreover, through the arrangement of the multiple-cavity type vessel section, taste of the cigarette is rich and diversified, smoke is strong in fragrance, and the smoke is full. By arranging the aluminum foil composite forming paper on the tobacco section, the problem that the core materials absorb moisture in air and thus the outer wrapping material is polluted and deforms is avoided.

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.
