Embodiment 1

[0032] An endless sheet of aluminum foil, optionally laminated on one side with a thin polymer layer such as polyethylene or polyethylene terephthalate layer, is rolled off a storage roll and passed through a coater which coats the aluminum foil Or the other side of the aluminum foil laminate is coated with a continuous layer of PEN, PTN or LCP by an extrusion coating device. The thickness of the aluminum foil is 5-50 μm, preferably 8-20 μm. The amount of polymer applied may vary, but is preferably of a thickness that dries to form a well-integrated and substantially complete layer. A suitable thickness of PEN, PTN or LCP is 1-100 μm, preferably 8-50 μm.

[0033] The patch packaging bag was then prepared by separating the laminate into two pieces to form the upper and lower parts of the patch packaging bag. The nicotine-containing patch is then placed on one sheet and the other sheet is placed on the patch by vacuum. Finally the packaging sheets are heat sealed along their ...

Abstract

A material for packaging a nicotine containing product comprising a polymer based on dimethyl-2,6-naphthalene dicarboxynate or 2,6-naphthalene dicarboxylic acid monomers, such as polyethylene naphtalate (PEN) or polytrimethylene naphtalate (PTN), or a liquid crystal polymer (LCP). The material may be laminated to another polymer or to metal foil.

Description

technical field [0001] The present invention relates to materials for packaging nicotine-containing products. Background of the invention [0002] Smoking has been one of the major health problems worldwide for many years. Smoking is now recognized as a major cause of, for example, high blood pressure and lung cancer. However, due to the addictive nature of nicotine, it is very difficult to get heavy smokers to stop smoking completely. An acceptable alternative to smoking is to provide nicotine in a non-smoking form or manner, such as chewing gum containing nicotine as an active ingredient, see eg US 3,845,217. Other products used as smoking substitutes are nicotine-containing tablets, see e.g. US 5,543,424, devices for inhaling nicotine through elongated tubes, see e.g. For a patch for transdermal administration of nicotine, see eg US 4,915,950 and the like. [0003] When packaging pharmaceuticals and food products, the main requirement is that th...
