Abstract
The utility model discloses a novel paper-plastic composite film, composed of a kraft paper, a resin adhesion layer and a vacuum aluminium-plating heat-sealing layer which are successively connected together from top to bottom and in the composite bonding through extruding. In the utility model, the kraft paper and the aluminium-plating heat-sealing layer are in composite bonding through once-extruding of the molten resin, thus improving the production efficiency, avoiding the residue of the organic solvent and saving the cost while meeting the requirement of stiffness of the profile and permitting the guarantee period.
Description
Technical field
The utility model relates to a kind of novel paper-plastic composite film.
Background technology
Archaism has cloud: " bread is the staff of life ", and the today of " food ", the desire that people buy food is more and more paid close attention to variation, novelty, the preservation and effect of packaging material and the safety and sanitation performance of packaging bag of packaging for foodstuff form except being subjected to food itself influences.
At present, the form of the food casing that occurs on the market also is varied, wherein more with the soft plastic sheeting of feel, adopt the less relatively of papery, more and more come into one's own but be accompanied by aspects such as the effect of putting on the shelf of packaging for foodstuff, three-dimensional stereovision and the well-pressed degree of profile, the application of paper is also extensive gradually, but technology is loaded down with trivial details relatively usually, and the production cycle is longer, and contains a small amount of organic solvent, there is potential threat in food hygiene, and cost is higher.
The utility model content
Technical problem to be solved in the utility model just provides that a kind of cost is low, production technology is simple, efficient is high, the novel paper-plastic composite film of safety and sanitation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of novel paper-plastic composite film is characterized in that: described novel paper-plastic composite film is made up of the brown paper that is connected in turn from top to bottom, resin-bonded layer, vacuum aluminum-coated hot sealing layer.
As preferably, described brown paper, resin-bonded layer are in the same place by extruding compoiste adhering with vacuum aluminum-coated hot sealing layer.
As preferably, described resin-bonded layer be resin-bonded a layer that at least a resin in polyethylene, polypropylene, the ethylene-vinyl acetate copolymer is formed.
As preferably, described vacuum aluminum-coated hot sealing layer is vacuum aluminum-coated polyethylene film or vacuum aluminum-coated cast polypropylene film.
Novel paper-plastic composite film of the present utility model is directly once extruded compoiste adhering with the brown paper and the hot sealing layer of aluminizing by molten resin, improved production efficiency, avoid organic solvent residue, when having satisfied the requirement of profile stiffness and shelf-life, saved cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the novel paper-plastic composite film of the utility model.
The specific embodiment
As shown in Figure 1, be the embodiment of novel paper-plastic composite film of the present utility model, the brown paper 1 that described novel paper-plastic composite film is connected in turn from top to bottom, resin-bonded layer 2, vacuum aluminum-coated hot sealing layer 3 are formed.Described resin-bonded layer 2 is the resin-bonded layer that at least a resin in polyethylene, polypropylene, the ethylene-vinyl acetate copolymer is formed.Described vacuum aluminum-coated hot sealing layer 3 is vacuum aluminum-coated polyethylene film or vacuum aluminum-coated cast polypropylene film.Described brown paper 1, resin-bonded layer 2 and vacuum aluminum-coated hot sealing layer 3 lump together by extruding composite junction.
