Problems solved by technology

[0003] Aluminum foil paper for cigarettes is one of the important packaging materials for cigarettes. The single-sided composite aluminum foil paper widely used at present, because of its thin texture and insufficient sealing performance, it is easy to make the filter element at the cigarette and the cigarette butt get wet, shorten the storage time, and cause waste and waste. loss, and when the filter element is damp, the adsorption effect becomes poor, and harmful substances are inhaled into the lungs, causing bodily harm; in addition, the existing aluminum foil paper is not firmly bonded, and it is easy to cause peeling between the layers of aluminum foil paper when it is heated and damp, which affects product quality.

Abstract

The invention discloses double-side attaching aluminum foil paper for a cigarette. The double-side attaching aluminum foil paper comprises an aluminum foil paper layer and a bonding layer, wherein butterfly grooves are uniformly formed in one side of the aluminum foil paper layer. A production process of the double-side attaching aluminum foil paper for cigarettes comprises the following steps ofS1, uniformly pressing one side of the double-side smooth aluminum foil paper into groove surfaces comprising butterfly grooves by a rolling pressing machine to obtain the aluminum foil paper layer; S2, uniformly coating an adhesive layer onto the groove surface of the aluminum foil paper layer to obtain a single-side aluminum foil paper; respectively putting the single-side aluminum foil paper onto placing frames arranged at the two sides; using a heat insulation conveying machine for simultaneously conveying the single-side aluminum foil paper at the left side and the right side to a position between attaching roller groups; performing pasting for bonding the adhesive layers of the two pieces of single-side aluminum foil paper to form the adhesive layer; S3, continuously feeding the pasted aluminum foil paper into shaping roller groups to be pressed and shaped; performing air cooling and edge cutting to obtain a finished product. The prepared double-side pasting aluminum foil paper for the cigarette has a good dampproof effect, and can be stored for a long time in various environments.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil paper, and in particular relates to double-sided laminated aluminum foil paper for cigarettes. Background technique [0002] With the development of society and economy, the packaging of commodities is also constantly updated. Packaging materials based on paper and plastic films have been gradually replaced by exquisite and beautiful aluminum foil paper. The use of aluminum foil paper is increasing. Production brings new business opportunities. [0003] Aluminum foil paper for cigarettes is one of the important packaging materials for cigarettes. The single-sided composite aluminum foil paper widely used at present, because of its thin texture and insufficient sealing performance, it is easy to make the filter element at the cigarette and the cigarette butt get wet, shorten the storage time, and cause waste and waste. loss, and when the filter element is damp, the adsorption effect becomes ...
