Description

BOPP printing plastic-free composite film

technical field

The utility model relates to a film, in particular to a BOPP printed plastic-free composite film.

Background technique

With the improvement of people's living standards, more and more vegetarian food has entered people's lives, and the packaging film requirements for instant food are getting higher and higher. BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, Odorless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. After corona treatment, BOPP film has good printing adaptability, and can be overprinted to obtain exquisite appearance effect, so it is often used as the surface layer material of composite film. However, the heat resistance and stretchability of existing packaging films cannot meet the requirements of use.

Utility model content

The utility model overcomes the deficiencies of the prior art and provides a BOPP printed plastic-free composite film with better heat resistance and protection performance.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A BOPP printing plastic-free composite film, comprising at least four-layer structure; the four-layer structure is respectively a polyamide homopolymer layer, an adhesive polyolefin layer, a polyolefin layer and a polypropylene layer; the polypropylene A printing layer is compounded under the layer; an antistatic layer is compounded on the polyamide homopolymer layer; the adhesive polyolefin layer has a thickness of 18 to 24 mm; and the protective layer has a thickness of 0.2 to 0.8 mm.

A further technical solution is that the adhesive polyolefin layer can be shirred.

A further technical solution is that the thickness of the antistatic layer is 0.1 to 0.5 mm.

A further technical solution is to compound a layer of antistatic layer on the printing layer.

A further technical solution is to compound a matting layer on the printing layer.

A further technical solution is that the polyamide homopolymer layer, the adhesive polyolefin layer, the polyolefin layer and the polypropylene layer are compounded sequentially.

Compared with the prior art, the beneficial effect of the utility model is: the utility model has good antistatic properties, not only can greatly save costs in the production process and transportation process, but also has good heat resistance and stretchability when used Antibacterial and antibacterial protection function, while satisfying the use thickness, the thickness specification of the new type of this embodiment is reduced compared with the traditional packaging film, and the convenience of use is improved.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further elaborated.

As shown in Figure 1, Figure 1 shows a structural diagram of an embodiment of the present invention, the present embodiment BOPP printing non-adhesive plastic composite film, including at least four layers of structure; the four layers of structure are respectively polyamide homopolymer Material layer 1, adhesive polyolefin layer 2, polyolefin layer 3 and polypropylene layer 4, and polyamide homopolymer layer, adhesive polyolefin layer, polyolefin layer and polypropylene layer are sequentially compounded; The composite film in this embodiment has good heat resistance and stretchability, and the adhesive polyolefin layer can be shirred.

During use, a printing layer 5 is compounded under the polypropylene layer; preferably, a matting layer can be compounded on the printing layer. An antistatic layer can be compounded on the polyamide homopolymer layer; in order to ensure the antistatic effect, but reduce the thickness of the packaging film at the same time, the thickness of the antistatic layer in this embodiment is 0.1 to 0.5 mm. The adhesive polyolefin layer has a thickness of 18 to 24 mm; the protective layer has a thickness of 0.2 to 0.8 mm. Compared with the traditional packaging film, the thickness specification is reduced, which improves the convenience of use.
