Abstract
The utility model relates to a packaging paper-plastic and plastic-plastic composite structure, in particular to a polarity composite film which is characterized by comprising a base film and a polarity precoating film, wherein the polarity precoating film is bonded on a base body by a secondary functional layer of the polarity precoating film; the base body is paper or base film; the polarity precoating film mainly comprises a main functional layer, a core layer and a secondary functional layer, the core layer is positioned between the main functional layer and the secondary functional layer, the material of the main functional layer is polarity plastics, the material of the secondary functional layer is adhesive, and the secondary 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 paper-mould, mould-plastic composite structure.
Background technology
Film is compounded on wrapping paper or the plastics, adopts coating viscosity glue on paper or plastics usually, then heating, mucous membrane.Exist complex process, production equipment requirement height, the high deficiency of production cost.Simultaneously, the level of paper-plastic composite structure that current packaging is used, mould-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, polarity composite membrane that production cost is low.
To achieve these goals, the technical solution of the utility model is: the polarity composite membrane, it is characterized in that it is made up of matrix and polarity pre-coating film, the polarity pre-coating film by the subfunction layer heat seal of polarity pre-coating film on matrix; Matrix is paper or base film; The polarity pre-coating film is made up of function of tonic chord layer, sandwich layer, subfunction layer, and sandwich layer is between function of tonic chord layer and subfunction layer, and the material of function of tonic chord layer is a polar plastic materials, and the material of subfunction layer is a bonding agent, and the heat seal of subfunction layer is on sandwich layer.
The beneficial effects of the utility model are: adopt said structure, it is simple in structure.Adopt on the sandwich layer and scribble subfunction layer (bonding agent) in advance, during use, pre-coating film directly contact the subfunction layer thermal synthesis one (and coating viscosity glue) again with wrapping paper or plastics, use simply, make things convenient for, and production cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-function of tonic chord layer, 2-sandwich layer, 3-subfunction layer, 4-matrix.
The specific embodiment
As shown in Figure 1, the polarity composite membrane, matrix 4 and polarity pre-coating film are formed, and the polarity pre-coating film is by the subfunction layer heat seal (85～120 ℃ of heat-seal temperatures) on matrix of polarity pre-coating film; Matrix 4 is paper or base film;
The polarity pre-coating film, it is made up of function of tonic chord layer 1, sandwich layer 2, subfunction layer 3, and sandwich layer 2 is between function of tonic chord layer 1 and subfunction layer 3; The material of function of tonic chord layer 1 is a polar plastic materials; The material of subfunction layer 3 is a bonding agent, and the heat seal of subfunction layer is on base layer.Function of tonic chord layer 1 is with sandwich layer 2 heat seals.
The material of sandwich layer 2 is polypropylene, polystyrene, polyamide, modified poly ethylene or polyethylene.
Described polar plastic materials is phenolic resins, PET, PVC, PET or PETG.
Function of tonic chord layer 1 adopts polar plastic materials, but oil polish, mill flower, frost flower or printing etc.
The effect of subfunction layer 3 is and wrapping paper or plastic bonding 85～120 ℃ of heat-seal temperatures.
Described bonding agent is the 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.
