Patent number: 10472150Abstract: 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.Type: GrantFiled: July 12, 2016Date of Patent: November 12, 2019Assignee: R.J.

Patent number: 10420370Abstract: Provided herein is a tobacco packaging material, comprising a paper material coated with at least one polymer layer. The polymer layer comprises at least one repulpable polymer, and wherein the tobacco packaging material has a water vapor transmission rate (WVTR) that is at least 90% lower than the paper material. Further provided is a tobacco package comprising the tobacco packaging material, wherein the tobacco package is substantially free of any foil inner liner or polypropylene film. Further described is a method for making the tobacco packaging material, comprising extrusion coating at least one repulpable polymer onto a paper material to form a polymer layer, and optionally further depositing at least one atomic layer deposition (ALD) layer that comprises a metal oxide.Type: GrantFiled: November 17, 2014Date of Patent: September 24, 2019Assignee: R.J.
