Wrapping Paper

[0029] As clear from FIG. 1, an embodiment of wrapping paper 2 has a triple structure. The wrapping paper 2 includes translucent first and second paper layers 4, 6, where the first and second paper layers 4, 6 form the opposite surfaces of the wrapping paper 2. Desirably, the first and second paper layers 4, 6 are both made of glassine paper, for example. The basis weight of the glassine paper is selected within the range of 20 to 40 g / m2, more desirably, 25 to 35 g / m2. In a specified example, the basis weights of the first and second paper layers 4, 6 are each 30.5 g / m2.

[0030] The wrapping paper 2 further includes a moisture-proof layer 8 between the first and second paper layers 4, 6, where the moisture-proof layer is virtually made of paraffin wax. Here, the word “virtually” means that substances other than paraffin wax are allowed to be contained in the moisture-proof layer 8 to the extent that they do not have an adverse effect on the biodegradability of the moi...

Abstract

A cigarette package is provided with an outer box (44) and an inner pack (56) contained within the outer box (44), and the inner pack (56) includes a cigarette bundle and an inner wrapper (58) covering the cigarette bundle. The inner wrapper (58) has first and second paper layers (4, 6) forming the opposite surfaces of the inner wrapper (58), and a moisture-proof layer (8) interposed between the first and second paper layers (4, 6), the moisture-proof layer (8) is made of only paraffin wax and functions also as an adhesive agent for bonding the first and second paper layers (4, 6).

Description

TECHNICAL FIELD [0001] This invention relates to an environmentally-friendly cigarette package which can exclude moisture and retain an aroma satisfactorily. This invention also relates to wrapping paper with high biodegradability suitable for such cigarette package, and a method and machine for manufacturing such wrapping paper. BACKGROUND ART [0002] The cigarette package comprises an outer box and an inner pack contained within the outer box, and the inner pack includes a bundle of smoking articles such as cigarettes or filter cigarettes and an inner wrapper, that is, wrapping paper covering the smoking-article bundle. [0003] For such inner wrapper, aluminum-vapor-deposited paper is generally used. The aluminum-vapor-deposited paper has a paper layer and an aluminum film vapor-deposited on one surface of the paper layer. Such aluminum film is very thin, so that the aluminum-vapor-deposited paper is insufficient in respect of the capacity to block moisture and air. Thus, regarding ...
