Abstract

The utility model provides a kind of BOPP cigarette film structure for taking into account glossiness performance and anti-blocking properties, including upper resist blocking and that layer, upper photic zone, lustre adding layer, upper hot sealing layer, middle layer, lower antistatic layer, lower hot sealing layer and lower resist blocking and that layer, each layer is set gradually from top to bottom, upper resist blocking and that layer surface is attached with antifoggant, the upper photic zone is polyethylene terephthalate layer, the lustre adding layer is nano zine oxide, and the upper resist blocking and that layer and lower resist blocking and that layer are polymethacrylates layer.In the utility model, resist blocking and that layer, the material of photic zone and lustre adding layer, size cooperate, and make glossiness, mist degree close to traditional structure, and resistance to blocking can be improved, and be a kind of new thin film structure for taking into account two kinds of performances.

Description

A kind of BOPP cigarette film structure for taking into account glossiness performance and anti-blocking properties

Technical field

The utility model belongs to BOPP cigarette film structure technical field of improvement, especially one kind and takes into account glossiness performance and anti-sticking The even BOPP cigarette film structure of performance.

Background technique

A kind of important application of BOPP film is the packaging for cigarette, i.e. BOPP cigarette film, is widely used in small In the packaging of packet and item packet.Traditional BOPP cigarette film passes through three-layer co-extruded technique and biaxial tension system by a variety of polypropylene functional materials At having certain barriers function to smell and moisture, the cigarette film performance of the type includes resistance to blocking energy, antistatic property and light Learn performance, wherein resistance to blocking can and optical property mutually restrict, i.e., resistance to blocking energy difference be because BOPP cigarette film surface excessively Smooth, BOPP cigarette film surface is formed caused by vacuum, and be added after anti-adhesive substances the optical property of BOPP cigarette film can be caused compared with Big negative effect, and traditional BOPP cigarette film has preferable optical property, but resistance to blocking can be poor, so tradition BOPP Cigarette film can no longer meet higher and higher performance requirement, be badly in need of the novel B OPP of a kind of firm resistance to blocking energy and optical property Cigarette film.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is structurally reasonable, by resist blocking and that layer, light transmission The common cooperation of layer and lustre adding layer to improve simultaneously resistance to blocking can and one kind of optical property take into account glossiness performance and anti-sticking The even BOPP cigarette film structure of performance.

The technical scheme adopted by the utility model is that:

A kind of BOPP cigarette film structure for taking into account glossiness performance and anti-blocking properties, it is characterised in that: including upper resist blocking and that Layer, upper photic zone, lustre adding layer, upper hot sealing layer, middle layer, lower antistatic layer, lower hot sealing layer and lower resist blocking and that layer, each layer from up to Under set gradually, upper resist blocking and that layer surface is attached with antifoggant, and the upper photic zone is polyethylene terephthalate layer, institute Stating lustre adding layer is nano zine oxide, and the upper resist blocking and that layer and lower resist blocking and that layer are polymethacrylates layer.

Further, the upper hot sealing layer is linear low density polyethylene layer, and the lower hot sealing layer is total for polypropylene random Polymers layer, the middle layer are homopolypropylene layer, and the antistatic layer is polyether ester amides layer.

Further, the upper photic zone and lustre adding layer with a thickness of 1~1.5 micron.

Further, the upper resist blocking and that layer and lower resist blocking and that layer with a thickness of 0.05~0.08 micron.

Further, the upper hot sealing layer and lower hot sealing layer with a thickness of 1.2~1.5 microns.

Further, the base with a thickness of 10~15 microns.

Further, the antistatic layer with a thickness of 0.3~0.6 micron.

The advantages and positive effects of the utility model are as follows:

In the utility model, upper hot sealing layer is linear low density polyethylene layer, and lower hot sealing layer is polypropylene random copolymer Layer, middle layer are homopolypropylene layer, and antistatic layer is polyether ester amides layer, four-layer structure are formed through coextrusion process, in upper heat Sealing surface coats lustre adding layer, in the layer surface coating upper photic zone that adds lustre to, distinguishes on upper photic zone surface and lower heat-sealing layer surface Painting is covered with resist blocking and that layer and lower resist blocking and that layer, and resist blocking and that layer, the material of photic zone and lustre adding layer, size cooperate, and makes gloss Degree, mist degree are close to traditional structure, and resistance to blocking can be improved, and be a kind of novel thin film knot for taking into account two kinds of performances Structure.

Detailed description of the invention

Fig. 1 is the structure chart of the utility model.

Specific embodiment

Below with reference to embodiment, the present invention will be further described, and it is not limited that following embodiments, which are illustrative, , the protection scope of the utility model cannot be limited with following embodiments.

A kind of BOPP cigarette film structure for taking into account glossiness performance and anti-blocking properties, as shown in Figure 1, the wound of the utility model Newly it is: including upper resist blocking and that layer 1, upper photic zone 2, lustre adding layer 3, upper hot sealing layer 4, middle layer 5, lower antistatic layer 8, lower heat-sealing Layer 7 and lower resist blocking and that layer 6, each layer is set gradually from top to bottom, and upper resist blocking and that layer surface is attached with antifoggant, the upper photic zone For polyethylene terephthalate layer, the lustre adding layer is nano zine oxide, and the upper resist blocking and that layer and lower resist blocking and that layer are equal For polymethacrylates layer.

In the present embodiment, upper hot sealing layer is linear low density polyethylene layer, and lower hot sealing layer is polypropylene random copolymer layer, Middle layer is homopolypropylene layer, and antistatic layer is polyether ester amides layer.
