Abstract

The utility model relates to a moisture-proof laser smoke film, belonging to the technical field of packaging materials. The moisture-proof laser smoke film is characterized by comprising a surface layer (1), a first blocking layer (2), a middle layer (3), a second blocking layer (4), a bottom layer (5) and an aluminium plating layer (6) in sequence; the surface layer (1) is a copolymerization PP layer; the first blocking layer (2) is a high-crystallization PP layer; the middle layer (3) is a homopolymerization PP layer; the second blocking layer (4) is a high-crystallization PP layer; the bottom layer (5) is a copolymerization PP layer; and the aluminium plating layer (6) is a laser aluminium plating layer. The moisture-proof laser smoke film has the laser aluminium plating layer, not only has the novel and beautiful appearance effects, simultaneously also has high a technical anti-counterfeit function, adds the first blocking layer and the second blocking layer, effectively blocks the oxygen and steam from penetration, prolongs the quality guarantee period of cigarettes and is applicable to the humid areas in the south.

Description

Moistureproof radium-shine cigarette film

(1) technical field

The utility model relates to a kind of cigarette film, the radium-shine cigarette film of particularly a kind of protection against the tide.Belong to field of packaging material.

(2) background technology

Tobacco business once used multiple material on the tobacco bale Wrapping films, comprise glass paper, PVC coated film, PVDC coated film, BOPP cigarette film etc.BOPP cigarette film becomes the preferred material of cigarette package because of the heat-sealing scope with good optical performance, broad, higher heat seal strength, stronger aqueous vapor obstructing capacity, homogeneous thickness, the shrinkage percentage modification scope of broad and the good incomparable characteristic of other materials such as deflection.

Traditional packaging cigarette film is a three-decker, and in southern humid area, the humidity height can not well intercept aqueous vapor and see through, and causes the shelf-life of cigarette to shorten.And do not have antiforge function, can not satisfy the terminal user of cigarette enterprise, the demand attractive in appearance and false proof the cigarette film as the cigarette film.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of protection against the tide radium-shine cigarette film, and it has the anti-fraud functional while, can prolong the shelf-life of cigarette.

The purpose of this utility model is achieved in that the radium-shine cigarette film of a kind of protection against the tide, it is characterized in that: it comprises surface layer, first barrier layer, interlayer, second barrier layer, bottom and the aluminium coated that sets gradually; Described surface layer is a copolymerization PP layer, and described first barrier layer is high crystallization PP layer, and described interlayer is the homopolymerization PP layer, and described second barrier layer is high crystallization PP layer, and described bottom is a copolymerization PP layer, and described aluminium coated is the citicall limited aluminium layer.

The beneficial effect of the moistureproof radium-shine cigarette film of the utility model is:

1) citicall limited aluminium layer not only has novelty, beautiful appearance, also has the hightech antiforge function simultaneously.

2) increase by first barrier layer, second barrier layer, effectively blocking oxygen, aqueous vapor see through, and prolong the shelf-life of cigarette, are applicable to southern humid area.

(4) description of drawings

Fig. 1 is the section structure scheme drawing of the moistureproof radium-shine cigarette film of the utility model.

Among the figure:

Surface layer 1, first barrier layer 2, interlayer 3, second barrier layer 4, bottom 5, aluminium coated 6.

(5) specific embodiment

Referring to Fig. 1, the radium-shine cigarette film of a kind of protection against the tide that the utility model relates to, it is made up of the surface layer 1 that sets gradually, first barrier layer 2, interlayer 3, second barrier layer 4, bottom 5 and aluminium coated 6;

Described surface layer 1 is copolymerization PP layer, and described first barrier layer 2 is high crystallization PP layer, and described interlayer 3 is the homopolymerization PP layer, and described second barrier layer 4 is high crystallization PP layer, and described bottom 5 is copolymerization PP layer, and five layer materials adopt co-extrusion technology to make through biaxial tension.

The bottom 5 of the biaxially oriented film that makes is provided with aluminium coated 6, and described aluminium coated 6 is the citicall limited aluminium layer, and antifalse effect is good and attractive in appearance.

Described high crystallization PP is meant the PP of crystallinity more than 98%.

Claims

1. radium-shine cigarette film of protection against the tide, it is characterized in that: it comprises surface layer (1), first barrier layer (2), interlayer (3), second barrier layer (4), bottom (5) and the aluminium coated (6) that sets gradually;

Described surface layer (1) is a copolymerization PP layer, described first barrier layer (2) is high crystallization PP layer, and described interlayer (3) is the homopolymerization PP layer, and described second barrier layer (4) is high crystallization PP layer, described bottom (5) is a copolymerization PP layer, and described aluminium coated (6) is the citicall limited aluminium layer.
