Abstract
The utility model discloses a multilayer is crowded heavily wrapping bag of separation type altogether, including skin, gluing layer multilayer, barrier layer multilayer and inlayer. The blown film is the cylinder, and both sides can " M shape " hem, the membrane is thick to be 80 250 the micron. Outer polyethylene (PE) or (polypropylene PP) layer of being, the inlayer is the PE layer, the barrier layer is polyamide PA (or polydiethylene terephthalate PET, ethylene - ethonal copolymer EVOH, polyvinylidene chloride PVDC, gather the inferior propyl ester PPC of carbonic acid etc. ) layer. From outer extremely interior PE layer, gluing layer, barrier layer, gluing layer, the PE layer of being respectively. With the ordinary PE that does not have separation nature heavily the wrapping bag compare, the multilayer that has a separation nature crowded heavily wrapping bag altogether can prevent not only that grain from absorbing the environment peculiar smell, preventing that the moisture absorption from going mildy rottenly, the oxygen infiltration in in addition can the separation environment results in the grain oxidation deterioration, can be applicable to the evacuation that is arranged in the inner wrapping at present even, fill fresh -keeping technique such as carbon dioxide, rotten loss among the storage and transport process such as greatly reduced grain.
Description
Technical field
The utility model relate to a kind of multi-layer co-extruded isolation-type heavily packaging bag, specifically one be applicable to pack rice, cereal and
It needs the packaging bag of the packaging of anti-oxidation raw material, belongs to obstruct based packaging material technical field.
Background technology
At present, heavily packaging bag mainly includes Polywoven Bag and multi-wall paper bag and the heavily packaging bag of co-extrusion PE film etc..Co-extrusion PE film
Heavily packaging bag is owing to can form heavily packaging bag, also referred to as FFS with film roll form for the full automatic shaping filling system of packing
Bag.Although the most domestic Polywoven Bag and the multi-wall paper bag of being used mostly is as heavily packaging bag, but the height that FFS bag has with it
Sealing property and high packaging efficiency just receive more and more attention, and have obtained extensively in raw material of industry fields such as plastic grain raw materials
Application.But woven bag the most commonly used for the product such as rice, coarse cereals, the most heavily packaging bag and paper bag, the most easily absorb
Environmental odors, and easily make moist, oxidation deterioration.Therefore the plastic foil heavily packaging bag with barrier is used not only to be possible to prevent
Grain absorbs environmental odors, prevents moisture absorption moldy metamorphism, and the oxygen infiltration that can intercept in environment causes grain oxidation deterioration,
Even go for being currently used for the preservation techniques such as the vacuumizing of middle inner wrapping, filling CO 2, be substantially reduced grain storage and transportation mistake
Loss in journey.Although common PE film heavily packaging bag can reach the purpose of sealed damp-proof, but because PE film has higher oxygen
Transmitance and carbon dioxide transmission rate, i.e. barrier property are poor, it is difficult to prevent the oxygen in environment from penetrating into and cause grain oxidation deterioration,
More be not applied for vacuumizing, the grain fresh keeping technology such as filling CO 2, therefore, devise a kind of multilayer for the problems referred to above
The heavily packaging bag of co-extrusion isolation-type.
Utility model content
The problem existed for above-mentioned prior art, the utility model provides a kind of multi-layer co-extruded isolation-type heavily packaging bag, has knot
Structure is compact, has good barrier property, and to oxygen, carbon dioxide, water, the advantage such as the barriering effect of smell etc. is good, by excellent
Change overall structure, meet difference and use requirement.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multi-layer co-extruded isolation-type heavily packaging bag, described
The heavily packaging bag of multi-layer co-extruded isolation-type includes outer layer, adhesive layer, barrier layer, adhesive layer and internal layer five tunic；Described multi-layer co-extruded
For the cylindrical shape flattened after isolation-type heavily packaging bag blown film, total film thickness is 80-250 micron.
Further, one during described adhesive layer is the graft-modified polymers of TIE viscous ionic type resin or maleic anhydride etc. or
Mixing.
Further, described outer layer is polyethylene (PE) layer；Described internal layer is PE layer；Described barrier layer be polyamide PA layer,
Polyethylene terephtalate layer, ethylene-vinyl alcohol copolymer evoh layer, PVF polyvinylidenechloride layer,
Poly (propylene carbonate) PPC layer one therein.
Further, described outer layer is polypropylene (PP) layer；Described internal layer is PE layer；Described barrier layer be PA layer, pet layer,
Evoh layer, PVDC layer or PPC layer one therein.
Further, described internal layer is that multilayer PE layer is connected with barrier layer by adhesive layer；Described barrier layer be multilayer PA, PET,
EVOH, PVDC or PPC layer passes through adhesive layer each other or is joined directly together；Described barrier layer is by adhesive layer and with multilayer PE
The outer layer of layer or the outer layer with multilayer PP layer are connected.
Further, it is " M " shape after described multi-layer co-extruded isolation-type heavily packaging bag both sides flanging, after sealing, becomes bag.
The beneficial effects of the utility model are: this multi-layer co-extruded isolation-type heavily packaging bag has compact conformation, has good barrier
Can, to oxygen, carbon dioxide, water, the barriering effect of smell etc. is good, is suitable for promoting the use of.
