Abstract
The utility model discloses a solvent-free multilayer composite foodstuff packaging film and a packaging bag. Both the packaging film and the packaging bag are of a composite structure composed of a polyester film surface layer, a polyester film middle layer and a polyethylene film heat-seal bottom layer respectively, wherein the above layers are sequentially bonded together as a whole by means of a 100% solid solvent-free type adhesive. According to the technical scheme of the utility model, the polyester film surface layer, the polyester film middle layer and the polyethylene film heat-seal bottom layer are sequentially bonded together as a whole by means of the 100% solid solvent-free type adhesive. By means of the 100% solid solvent-free type adhesive, the safety problems of organic solvents, such as the environmental pollution caused by volatile organic solvents, the occurrence of potential fire hazards and explosion hazards, and the like, can be avoided. Therefore, the packaging film and the packaging bag has the advantages of environmental protection, safety, and low energy consumption.
Description
Technical field
The utility model relates to package packing supplies field, relates in particular to a kind of solvent-free MULTILAYER COMPOSITE food package film and packaging bag.
Background technology
Existing food package film bag material adopts Biaxially oriented polypropylene, aluminium foil and polyethylene structure, but because the mechanical strength of aluminium foil is not high, easily tear up, fracture, barrier property can be because being subject to the impact of pin hole number and pore size, and often occur in production and application process that aluminium foil is lost, break, cause the situations such as food spoilage, thereby affect quality and the shelf-life of food.
At present, the MULTILAYER COMPOSITE food package film bag of the composite structure consisting of mylar top layer, mylar middle level and polyethylene foil heat-sealing bottom comes out, and this MULTILAYER COMPOSITE food package film bag has the advantages such as load-carrying capacity is strong, the phenomenon that is difficult for producing aluminium lamination fracture, good barrier property.But current MULTILAYER COMPOSITE food package film bag adopts rosin synthesizing water-solubility plastic sheeting adhesion agent equal solvent type adhesion agent, exists the safety problems such as organic solvent volatilization contaminated environment and fire and hidden peril of explosion.The rise of the solvent price that the oil of in addition mainly take is raw material, and energy-conservation needs, be restricted the development of solvent-based adhesive, EPA's regulation abroad: per gallon adhesion agent, in coating operation, must not distribute 2.9 pounds of above solvents.And being coated with at home the solvent-based adhesive solid content that uses in industry generally 25%, solvent evaporates amount is 6 pounds of left and right of per gallon.Therefore, greatly affect the quality of food.
Utility model content
The utility model provides a kind of solvent-free MULTILAYER COMPOSITE food package film and packaging bag, has advantages of environmental friendliness, safety and low power consuming.
The utility model is realized by the following technical solutions:
A MULTILAYER COMPOSITE food package film, described packaging film is successively by 100% the bonding as a whole composite structure forming of solid solventless type adhesive by mylar top layer, mylar middle level and polyethylene foil heat-sealing bottom.
Wherein, the thickness on described mylar top layer is 12～36 μ m.
Wherein, described mylar middle level is vacuum aluminum-coated laminated polyester film.
The thickness of the aluminium lamination wherein, being coated with on described mylar middle level is 0.025 μ m.
A MULTILAYER COMPOSITE food pack, described packaging bag is successively by 100% the bonding as a whole composite structure forming of solid solventless type adhesive by mylar top layer, mylar middle level and polyethylene foil heat-sealing bottom.
Wherein, the thickness on described mylar top layer is 12～36 μ m.
Wherein, described mylar middle level is vacuum aluminum-coated laminated polyester film.
The thickness of the aluminium lamination wherein, being coated with on described mylar middle level is 0.025 μ m.
The beneficial effects of the utility model are: the solid solventless type adhesive of the utility model employing 100% is bonding as a whole successively by mylar top layer, mylar middle level and polyethylene foil heat-sealing bottom.There is not the safety problems such as organic solvent evaporates contaminated environment and fire and hidden peril of explosion in 100% solid solventless type adhesive, therefore the utlity model has the advantage of environmental friendliness, safety and low power consuming.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of solvent-free MULTILAYER COMPOSITE food package film of the utility model and packaging bag.
In figure:
1-mylar top layer, 2-mylar middle level, the solid solventless type adhesive of 3-100%, 4-polyethylene foil heat-sealing bottom.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
As shown in Figure 1, a kind of solvent-free MULTILAYER COMPOSITE food package film of the utility model is successively by 100% the bonding as a whole composite structure forming of solid solventless type adhesive 3 by mylar top layer 1, mylar middle level 2 and polyethylene foil heat-sealing bottom 4.
In one embodiment, the thickness on mylar top layer 1 is 12～36 μ m.Mylar middle level 2 is vacuum aluminum-coated laminated polyester film, and the thickness of the aluminium lamination being coated with on mylar middle level 2 is 0.025 μ m.In this embodiment, mylar middle level 2 surface vacuums plate aluminium lamination, are can similar aluminium foil due to the performance of vacuum aluminum-coated mylar, and this film can replace aluminium foil to be applied to packaging for foodstuff, can economize in a large number aluminium, so just can reduce the cost of manufacturing packaging film bag.
