Abstract
The utility model relates to a packaging plastic-plastic composite structure, in particular to a film composite structure which is characterized by comprising a base film and a precoating film, wherein the precoating film is bonded on the base film by the coating functional layer in a thermal way. The precoating film comprises a secondary functional layer, a core layer and the coating functional layer, wherein the core layer is positioned between the secondary functional layer and the coating functional layer; the material of the secondary functional layer is mainly polypropylene, the material of the core layer is modified polypropylene, the material of the coating functional layer is adhesive, and the coating functional layer is bonded on the core layer in a thermal way. The utility model has simple structure and low production cost.
Description
Technical field
The utility model relates to a kind of wrapping moulding-plastic composite structure.
Background technology
Film is compounded on the wrapping plastics, adopts coating viscosity glue on plastics usually, then heating, mucous membrane.Exist complex process, production equipment requirement height, the high deficiency of production cost.Simultaneously, current packaging is used moulds-and the level of plastic composite structure is more, complex structure.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, film composite construction that production cost is low.
To achieve these goals, the technical solution of the utility model is: the film composite construction, it is characterized in that it is made of base film and pre-coating film, pre-coating film by the coating functional layer heat seal of pre-coating film on base film.
Described pre-coating film, it is made up of subfunction layer, sandwich layer, coating functional layer, and sandwich layer is between subfunction layer and coating functional layer; The material of subfunction layer is mainly polypropylene, and the material of sandwich layer is a modified poly ethylene, and the material of coating functional layer is a bonding agent, and the heat seal of coating functional layer is on sandwich layer.
The material of described base film is bidirectional stretching polypropylene film, biaxial tension pet film, biaxially oriented polystyrene film, two-way stretching polyamide film, cast polypropylene film or polyethylene film.
The beneficial effects of the utility model are: adopt said structure, it is simple in structure.Pre-coating film adopts on the sandwich layer and scribbles the coating functional layer in advance, and during use, pre-coating film directly will be coated with functional layer and contact thermal synthesis one (and coating viscosity glue) again with wrapping plastics, use simply, make things convenient for, production cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-subfunction layer, the 2-sandwich layer, 3-is coated with functional layer, 4-base film.
The specific embodiment
As shown in Figure 1, the film composite construction, it is made of base film 4 and pre-coating film, and pre-coating film is by coating functional layer 3 heat seals (85～120 ℃ of heat-seal temperatures) on base film 4 of pre-coating film.
Described pre-coating film, it is made up of subfunction layer 1, sandwich layer 2, coating functional layer 3, and sandwich layer 2 is between subfunction layer 1 and coating functional layer 3; The material of subfunction layer 1 is mainly polypropylene (PP), and the material of sandwich layer 2 is modified poly ethylene (PE), and the material of coating functional layer 3 is a bonding agent, and 3 heat seals of coating functional layer are on sandwich layer 2.Subfunction layer 1 is with sandwich layer 2 heat seals.
The effect of subfunction layer 1 is the outward appearance of film, by add additive (be incorporated as 0～3% of polypropylene quality, concrete additive determines with the need, as: add pigment of all kinds) in polypropylene, can change the outward appearance of film, as transparent or opaque; The subfunction layer also has antiseized effect.The effect of sandwich layer 2 is as carrier.The effect of coating functional layer 3 is and wrapping paper or plastic bonding 85～120 ℃ of heat-seal temperatures.
Described bonding agent is the modified EVA bonding agent.
The material of described base film is bidirectional stretching polypropylene film, biaxial tension pet film, biaxially oriented polystyrene film, two-way stretching polyamide film, cast polypropylene film or polyethylene film.
