Description
Technical field
The present invention relates to packaging material, particularly relate to a kind of compound blister insulation packaging material.
Background technology
At present, for packing the disposable ARTPackaging containers of isothermal liquid food, there are the shapes such as square, triangle, the thermoplastic outermost layer of usual these packing containers of manufacture, sandwich layer, thermoplastic intermediate layer, barrier layer, adhesive phase and thermoplastic innermost layer, also the low density polyethylene (LDPE) adopting high-pressure process to produce is had, polyester (waiting the laminate wrapping material of sandwich construction).These packing containers can pack some specific drugs, ice cream, cream, the cold fresh meat class of some shortening, biodiasmin drink (Yoghourt, chlorella yakult, taste congruence), the fruit juice, high-grade seafood etc. of Fresh Juice or the 100% Normal juice content food that needs constant temperature to pack.Chinese invention patent application prospectus is that the patent of CN1337914A discloses a kind of paper container package material, the constituting layer at least comprised has thermoplastic outermost layer, papery base layer, each constituting layer is also pressed said sequence lamination by barrier layer and thermoplastic innermost layer, but, this packaging material are in the extruding layer compression technology of manufacture process, serious necking phenomenon can be there is from during the die head film extrusion of extruder in barrier layer in molten condition, namely extrusion die dual-side can to middle shrinkage, even there is the phenomenon of breach in edge thickness inequality, papery base layer both sides can be made like this to be capped or cladding thickness uneven, it is complicated that this phenomenon causes there will be packaging material manufacturing process in actual use, product qualified rate is low, heat insulation effect is not obvious.
Summary of the invention
The object of this invention is to provide a kind of packaging material of the food needing long-term constant temperature to pack, solve the multinomial defect of current constant temperature packaging material for food.
Technical problem to be solved by this invention is: a kind of compound blister insulation packaging material, thickness 2.8-3.5mm, comprise Withstand voltage layer, plasticity insulating composite layer, fire-retardant PE film, on described fire-retardant PE layer, uniformly dispersing has blister salient point, and described plasticity insulating composite layer both sides are all connected with Withstand voltage layer, described fire-retardant PE film invests the Withstand voltage layer surface of side, described Withstand voltage layer and plasticity insulating composite layer and all pasted by adhesive hydraulic pressure between Withstand voltage layer and fire-retardant PE film.
Preferably, described plasticity insulating composite layer is corrugated corrugated paper structure.
Preferably, described Withstand voltage layer is polyester film material.
Preferably, described fire-retardant PE layer and the foaming micelle being evenly distributed with different size between Withstand voltage layer.
Preferably, described plasticity insulating composite layer thickness is the 1/4-1/3 of the gross thickness of packaging material.
Technical problem to be solved by this invention is to provide a kind of hydraulic pressure compound blister insulation packaging material, combine firmly between the Withstand voltage layer of these hydraulic pressure packaging material and plasticity insulating composite layer, material gross thickness is controlled rationally, to significantly reduce the weight of material, is convenient to transport.Thickness is about corrugated corrugated paper structure best results between gross thickness 1/4--1/3, and absorb heat few, poor thermal conductivity, has good function of heat insulation.Polyester film material structural strength is large, and lightweight, makes Withstand voltage layer resistance to pressure well slim and graceful again.In the surface uniform distribution blister bump of packaging material, can in the impact strengthening its improper pressure to external world.The qualification rate of the packing container made is high, the shelf lives of the food allowing palpus constant temperature preserve extends, and it in the fabrication process, during hydraulic pressure plasticity heat-insulation composite section material material, serious necking phenomenon can not occur, the serious energy and waste of raw materials can not be caused, significantly reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is a kind of schematic perspective view of compound blister insulation packaging material.
Fig. 2 is a kind of cross sectional representation of compound blister insulation packaging material.
Wherein: 1-fire-retardant PE film, 2-Withstand voltage layer, 3-Withstand voltage layer, 4-plasticity insulating composite layer.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of compound blister insulation packaging material of the present invention comprise fire-retardant PE film 5, Withstand voltage layer 6, plasticity insulating composite layer 7, Withstand voltage layer 8 successively, and polypropylene is the polypropylene containing ceramic catalyst.Compound blister insulation packaging material thickness 2.8-3.5mm, if Fig. 2 the superiors are fire-retardant PE layer 1, secondly be Withstand voltage layer 2, then be plasticity insulating composite layer 3, it is finally Withstand voltage layer 4, Withstand voltage layer and plasticity insulating composite layer and all pasted by adhesive hydraulic pressure between Withstand voltage layer and fire-retardant PE film, in conjunction with firmly.In manufacture process, serious necking phenomenon can not be there is during hydraulic pressure plasticity heat-insulation composite section material material, the serious energy and waste of raw materials can not be caused, significantly reduce manufacturing cost.Because plasticity insulation structure of voltage-sustaining layer intensity is low, so the combination of the Withstand voltage layer of multilayer, greatly can strengthen resisting of impulsive force to external world, the structure of container intensity made is large, uses more convenient.
In addition, the structure of the waveform corrugated paper of plasticity insulating composite layer 4, few to heat absorption amount, poor thermal conductivity, has good insulation and obtains feature.
It should be noted that Withstand voltage layer 2 and 3 is for polyester film material, belong to the polyester film of macromolecular material, isomery molecular structure has good stability, and resistance to pressure is splendid, and low cost of manufacture.
In the present embodiment, fire-retardant PE layer 1 and the foaming micelle of different size between Withstand voltage layer 2, make fire-retardant PE layer 1 surface form salient point, have the cushioning effect of pressure to external world.Plasticity insulating composite layer 4 THICKNESS CONTROL is at the 1/4-1/3 of the gross thickness for packaging material, and frivolous thickness has good machinability, and the gross weight reducing material is convenient to transport.
Based on above-mentioned, technical problem to be solved by this invention is to provide a kind of hydraulic pressure compound blister insulation packaging material, combines firmly, control rationally for material gross thickness between the Withstand voltage layer of these hydraulic pressure packaging material and plasticity insulating composite layer, significantly reduce the weight of material, be convenient to transport.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
