Abstract
A soft package bag for pesticide relates to the technical field of packaging pesticide. The soft package bag for pesticide comprises an outer layer, a middle layer, an inner layer and adhesive layers which are formed between the outer layer and the middle layer and between the middle layer and the inner layer because of adhesive joining. The inner layer of the soft package bag for pesticide is a multilayer coextrusion complex film and the middle of the layer is provided with a blocked layer. Compared with the prior art, the marked progress of the utility model mainly finds expression in: the inner layer of the utility model adopts the multilayer coextrusion complex film which is provided with the blocked layer, solving the technical problems of the separation and leakage of a complex layer of a package bag for pesticide when packaging liquid pesticide; the utility model can effectively increase ability of a package bag for liquid pesticide to resist load bearing and falling after packaging liquid pesticide. The application of the utility model has positive meaning for reducing environmental pollution during packaging, transporting and storing of pesticide.
Description
Technical field:
The utility model relates to a kind of packaging bag, particularly a kind of soft packaging bag that is suitable for the packing liquid agricultural chemicals.
Background technology:
In China, the packing of liquid pesticidal adopts glass bottle or plastic bottle more, adopts these packings to exist following problem: 1, the inefficacy and the environmental pollution of the agricultural chemicals that glass bottle easily causes because of fragmentation or seepage in transportation; 2, the package packing machine investment is big, and the cost of bottle is higher, and packing specification is few; 3, the packing production environment is polluted easily, has greatly influenced health of operators; 4, outer sign is because of directly being attached to the surface of bottle, therefore easy impaired coming off.Recently on the market a kind of liquid pesticide flexible package bag has appearred at home.Disclosing a kind of patent No. in the patent document of China is the liquid pesticide flexible package bag of ZL95204234.7, its packaging bag is made up of skin, middle level, internal layer, aluminium foil is adopted in its middle level, crucial internal layer adopts the chlorinated polypropylene film, the technical matters that exists is, organic solvents such as the not anti-dimethylbenzene of general polypropylene film, benzene cause swelling, generation seepage, the composite bed of polypropylene film to separate easily after the long-term storage, finally cause the leakage of whole packaging bag.
Summary of the invention:
Technical problem to be solved in the utility model is, designs a kind of pesticide flexible package bag, to solve the technical matters that long storage time liquid pesticidal packaging bag that prior art exists is easily leaked.
The technical scheme of the utility model technical solution problem is: it by skin, middle level, internal layer, skin and in interlayer and in the middle level reaches interlayer form because of the bonding adhesive linkage that forms, feature is, its internal layer is a multilayer copolymerized compound membrane for its internal layer, and this layer centre is provided with one deck barrier layer.
Multilayer copolymerized compound membrane can be multi-layer co-extruded polypropylene (CPP) film or multilaminar polyethylene (PE) film.
Barrier layer can be nylon (PA) or ethylene-vinyl alcohol (EVOH) resin bed, and to prevent the infiltration of toluene, the contour penetrating quality solvent of dimethylbenzene, actv. intercepts the leakage of organic solution.
The middle level can be aluminium foil or vacuum aluminum-coated polyethylene terephthalate (VMPET) film, and their light tight and good barrier property can prevent effectively that the light of agricultural chemicals from decomposing.
Skin can be polyethylene terephthalate (PET) or Biaxially oriented polypropylene (BOPP) film.Characteristics such as they have heat-resisting, toughness and chemical nature is good, suitable printing.
Adhesive linkage is a polyester type polyurethane, can strengthen the adhesive ability of above-mentioned each interlayer of packaging bag effectively, solves the problem of the anti-dimethylbenzene of packaging bag, pure Ammonia solvent.
Owing to adopt technique scheme, the utility model compared with prior art has obvious improvement, mainly show: its internal layer adopts the multilayer copolymerized compound membrane that is provided with barrier layer, solved the pesticides packaging bag and can take place when the packing liquid agricultural chemicals that composite bed separates, the technical matters of seepage phenomenon, effectively enhance liquid pesticides packaging bag behind the packing liquid agricultural chemicals anti-load and anti-drop ability; Its environmental pollution of promoting the use of reducing in pesticides packaging, transportation, the storage link has positive meaning.
Description of drawings:
Fig. 1 is a kind of example structure scheme drawing of optimal design;
Fig. 2 is the multilayer copolymerized compound membrane structural representation.
In the drawings: outer 1; Middle level 2; Internal layer 3; Adhesive linkage 4; Theca externa 5,8; Barrier layer 6; Adhesive linkage 7;
The specific embodiment:
In conjunction with Fig. 1, a kind of pesticide flexible package bag, it by outer 1, middle level 2, internal layer 3, outer 1 and 2 in middle level and in the middle level 2 and 3 of internal layers form because of the bonding adhesive linkage that forms 4.Its skin 1 is gathering benzene first diacid ethylene glycol membrane of lipoprotein or bidirectional stretching polypropylene film that chemistry is good, be suitable for printing.Its internal layer 3 is multilayer copolymerized compound membrane (with reference to Fig. 2), and multilayer copolymerized compound membrane can be multi-layer co-extruded polypropylene (CPP) film or multilaminar polyethylene (PE) film; The interlayer of multilayer copolymerized compound membrane 3 is a barrier layer 6, and barrier layer 6 can be nylon (PA) film or ethylene-vinyl alcohol (EVOH) resin bed, and what be positioned at barrier layer 6 outsides is the theca externa 5,8 of multilayer copolymerized compound membrane, and each layer is connected by adhesive linkage 7.Its middle level can be aluminium foil or vacuum aluminum-coated polyethylene terephthalate (VMPET) film.For strengthening the adhesive ability of each interlayer of packaging bag effectively, solve the problem of the anti-dimethylbenzene of packaging bag, pure Ammonia solvent, adhesive linkage 4,7 all adopts polyester type polyurethane.The thickness of the middle level 2 of this packaging bag, internal layer 3 and adhesive linkage 4 is as follows: the thickness in middle level 2 is 10-15 μ m; The thickness of internal layer 3 is 20-25 μ m; The thickness of adhesive linkage 4 is 5-10 μ m.
