Abstract
The utility model relates to a paper-plastic lamination used precoating plastic film, which comprises a plastic film layer (1) and a binding layer (2) of the ethylene vinyl acetate copolymer is the composite formed by heating and softening and coating on the surface of the plastic film layer (1) and being cooled and solidified, the plastic film layer (1) is the biaxial oriented polypropylene stretching film or the biaxial oriented polyester resin stretching film. The precoating plastic film is nonpoisonous when making and using, which has no pollution to the environment and meets the requirement of green products.
Description
Technical field
The utility model relates to the compound precoating plastic foil of using of a kind of paper.
Background technology
Along with the progress of expanding economy and society, packaging material except that package action, multiple function such as also need to have the commodity of beautifying, false proof, moistureproof, ventilative, fresh-keeping.Traditional wrapping paper far can not satisfy these requirements.In recent years Kai Fa plastic film for wrapping owing to have impressionability, protection against the tide, function such as false proof, usually be used for paper or the compound back of cardboard as packaging material.Traditional complex method is that plastic sheeting one side is at first applied oiliness or aqueous binder, sticks on then on paper or the cardboard.But for the cementability that improves adhesive, pliability etc., the polymer with chemical synthesis improves usually, therefore, no matter making this adhesive, or when using it, these chemical substances all can be brought harm to environment or human body, also can pollute the packaging product.
Summary of the invention
The purpose of this utility model is, provides a kind of paper the compound precoating plastic foil of using, and is nontoxic free from environmental pollution when making and use, and simple and convenient.
Realize the technical scheme of the utility model purpose: the compound precoating plastic foil of using of a kind of paper, by plastic film layers with stand thermal softening, be coated in the plastic sheeting laminar surface, the adhesive layer of the ethylene-vinyl acetate copolymer that is combined with each other behind the cooling curing is formed, and described plastic film layers is acrylic resin biaxially-stretched film or mylar biaxially-stretched film.
Technique effect of the present utility model: precoating plastic foil of the present utility model, its adhesive layer is thermoplastic ethylene-acetate ethylene copolymer.During use, soften the material that becomes to have viscosity again after being heated as the ethylene-vinyl acetate copolymer of adhesive layer, therefore, be easy to be combined with each other, be made into needed various paper composite article with paper or cardboard, very convenient.In addition, because ethylene-vinyl acetate copolymer has good flexibility, elasticity and the transparency, therefore, this adhesive layer can not influence the color, pattern of plastic film layers etc., can not influence the pliability of plastic film layers yet.As the acrylic resin biaxially-stretched film or the mylar biaxially-stretched film of plastic film layers, high temperature resistant, therefore, the temperature of softening ethylene-vinyl acetate copolymer adhesive layer can not make plastic film layers softening.
Owing to the ethylene-vinyl acetate copolymer of the acrylic resin that is used as the utility model plastic film layers or mylar and adhesive layer is all nontoxic, therefore, when producing and using precoating plastic foil of the present utility model, can not damage the environment and the person, more can not influence the product of packaging.
Description of drawings
Fig. 1 is the compound structural representation with the precoating plastic foil of the utility model paper.
The specific embodiment
Be further described in detail below in conjunction with 1 pair of the utility model of accompanying drawing.
As shown in Figure 1, the compound precoating plastic foil of using of paper of the present utility model, by plastic film layers 1 with stand thermal softening, be coated in plastic film layers 1 surface, the adhesive layer 2 of the ethylene-vinyl acetate copolymer that is combined with each other behind the cooling curing is formed, described plastic film layers 1 is acrylic resin biaxially-stretched film (being commonly called as the BOPP film), or mylar biaxially-stretched film (being commonly called as the BOPET film), and this biaxially-stretched film is called biaxial stretching film again.
Plastic film layers 1 of the present utility model is multi-layer co-extruded biaxially-stretched film, for example, and three-layer co-extruded, five layers of (containing four layers) co-extrusion or seven layers of (containing six layers) co-extrusion.It can be the light film (claiming flat film again) of the multi-layer co-extruded formation of same resin (for example acrylic resin or mylar), also can be the inferior light film (claiming matt film again) of the multi-layer co-extruded formation of different resins (for example acrylic resin the mixture of acrylic resin and high-density polyethylene resin) together, or the pearly-lustre film.
When making precoating plastic foil of the present utility model, can determine acrylic resin or the thickness of mylar biaxially-stretched film and the thickness of adhesive layer 2 according to client's needs as plastic film layers 1.The ethylene-vinyl acetate copolymer that is subjected to thermal softening is coated in the surface of plastic film layers 1, is compounded in behind the cooling curing on the plastic film layers 1, form adhesive layer 2, be precoating plastic foil of the present utility model.According to actual needs, also further roll-in, typing, cutting, rolling again.
During use, only need make adhesive layer 2 softening precoating plastic foil heating of the present utility model, roll-in be promptly made required paper composite article on required paper or cardboard.Can be hand-manipulated, be more suitable for pipelining, very simple and convenient.
Precoating plastic foil of the present utility model, can select to have different acrylic resin or mylar biaxially-stretched films such as different performance is for example false proof, pearly-lustre look, inferior light according to actual needs, as plastic film layers 1, all can not influence its original performance after compound with adhesive layer 2.
Claims (1)
1, the compound precoating plastic foil of using of a kind of paper, it is characterized in that: by plastic film layers (1) with stand thermal softening, be coated in plastic film layers (1) surface, the adhesive layer of the ethylene-vinyl acetate copolymer that is combined with each other behind the cooling curing (2) is formed, and described plastic film layers (1) is acrylic resin biaxially-stretched film or mylar biaxially-stretched film.
