Description
Technical field
The utility model relates to a kind of plastic composite packaging film, and more particularly, it relates to a kind of plastic flexible package film.
Background technology
Along with the development of packaging, transport industry, the packing instructions of product improve constantly, and the packing of product is modernization more and more, propose more and more higher requirement to packaging bag.At present, food and drug packing material manufacture have started the high-tech industry field stepping into worldwide concern.In China, the plastic flexible packaging material of food and medicine and manufacturing technology thereof have also been obtained suitable attention and development.
As the plastic flexible packaging material of food and medicine,, barrier property wet to resistance and mechanical strength have higher technical standard requirement, simultaneously, when a lot of packing of product, all need that there is certain effect of heat insulation, as precision component, vaccine, can produce thermal deformation or the easy commodity etc. that thermal chemical reaction occurs.And continue thisly simultaneously have that resistance is wet, barrier property, heat insulating function at present, and the plastic flexible package film that mechanical strength is high.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide one to have, and resistance is wet, barrier property, heat insulating function, and the plastic flexible package film that mechanical strength is high.
For achieving the above object, the utility model provides following technical scheme: a kind of plastic flexible package film, comprises the polyvinylchloride thermal insulation layer, ethylene-vinyl alcohol copolymer EVOH barrier layer and the polyamide PA protective layer that are combined with each other successively.
By adopting technique scheme, polyvinylchloride has difficult combustion, acid and alkali-resistance, antimicrobial, wear-resisting, the characteristic of environmental protection and heat-blocking action, ethylene-vinyl alcohol copolymer EVOH is to gas, smell, spices, solvent etc. present excellent blocking effect, polyamide PA has good mechanical property, heat resistance, mar proof, chemical proofing, self lubricity and anti-flammability, ethylene-vinyl alcohol copolymer EVOH intermediate layer is arranged at the middle fragility defect then improveing ethylene-vinyl alcohol copolymer EVOH and exist, make the utility model plastic flexible package film have good resistance by the compound of above three-layer plastic film to wet, barrier property, heat insulating function and mechanical strength.
The utility model is set to further: be respectively arranged with polyethylene polymer PE printed layers and polyethylene polymer PE safe floor outside described polyvinylchloride thermal insulation layer and polyamide PA protective layer.
By adopting technique scheme, because polyethylene polymer PE has odorless, nontoxic, feel ceraceous, there is excellent resistance to low temperature, chemical stability is good, the erosion of the most of soda acid of ability, be applicable to the Product labelling that the performances such as water resistant, oil and chemical substance are higher, the printing of vast source often by this materials application in advantages such as cosmetics, shampoo, washing and other household chemicals labels in use having moisture resistance, anti-extrusion to require, therefore be arranged on outermost layer, not easily wander off during printing, complete after printing, simultaneously can with direct food contact.
The utility model is set to further: be provided with the first polyolefin A DMER adhesive-layer between described polyvinylchloride thermal insulation layer and polyethylene polymer PE printed layers, is provided with the second polyolefin A DMER adhesive-layer between described polyamide PA protective layer and polyethylene polymer PE safe floor.
By adopting technique scheme, because the number of plies is too much therefore bonding by AD viscose glue, strengthen the connectivity robustness between a plastic sheeting.
The utility model is set to further: the thickness proportion of described polyethylene polymer PE printed layers, the first polyolefin A DMER adhesive-layer, polyvinylchloride thermal insulation layer, ethylene-vinyl alcohol copolymer EVOH barrier layer, the second polyolefin A DMER adhesive-layer, polyamide PA protective layer and polyethylene polymer PE safe floor is 2:1:2:2:2:1:2.
In sum, the utility model plastic flexible package film has that good resistance is wet, barrier property, heat insulating function and mechanical strength, and nontoxic, odorless, printing not easily wanders off, advantage smooth after printing.

Reference numeral: 1, polyethylene polymer PE printed layers; 2, the first polyolefin A DMER adhesive-layer; 3, polyvinylchloride thermal insulation layer; 4, ethylene-vinyl alcohol copolymer EVOH barrier layer; 5, the second polyolefin A DMER adhesive-layer; 6, polyamide PA protective layer; 7, polyethylene polymer PE safe floor.
Detailed description of the invention
With reference to Fig. 1, the utility model plastic flexible package film is described further.
As shown in Figure 1; a kind of plastic flexible package film; comprise the polyethylene polymer PE printed layers 1, polyvinylchloride thermal insulation layer 3, ethylene-vinyl alcohol copolymer EVOH barrier layer 4, polyamide PA protective layer 6 and the polyethylene polymer PE safe floor 7 that are combined with each other successively, described polyvinylchloride thermal insulation layer 3, ethylene-vinyl alcohol copolymer EVOH barrier layer 4 and polyamide PA protective layer 6 hot pressing form.Polyvinylchloride has difficult combustion, acid and alkali-resistance, antimicrobial, wear-resisting, the characteristic of environmental protection and heat-blocking action, ethylene-vinyl alcohol copolymer EVOH is to gas, smell, spices, solvent etc. present excellent blocking effect, polyamide PA has good mechanical property, heat resistance, mar proof, chemical proofing, self lubricity and anti-flammability, ethylene-vinyl alcohol copolymer EVOH barrier layer 4 is arranged at the middle fragility defect then improveing ethylene-vinyl alcohol copolymer EVOH and exist, make the utility model plastic flexible package film have good resistance by the compound of above three-layer plastic film to wet, barrier property, heat insulating function and mechanical strength.
Preferably; described polyvinylchloride thermal insulation layer 3 is located between polyethylene polymer PE printed layers 1 and ethylene-vinyl alcohol copolymer EVOH barrier layer 4, and described polyethylene polymer PE safe floor 7 is located between ethylene-vinyl alcohol copolymer EVOH barrier layer 4 and polyamide PA protective layer 6.Because polyethylene polymer PE has odorless, nontoxic, feel ceraceous, there is excellent resistance to low temperature, chemical stability is good, the erosion of the most of soda acid of ability, be applicable to the Product labelling that the performances such as water resistant, oil and chemical substance are higher, the printing of vast source often by this materials application in advantages such as cosmetics, shampoo, washing and other household chemicals labels in use having moisture resistance, anti-extrusion to require, therefore be arranged on outermost layer, not easily wander off during printing, complete after printing, simultaneously can with direct food contact.
Preferably; be provided with the first polyolefin A DMER adhesive-layer 2 between described polyvinylchloride thermal insulation layer 3 and polyethylene polymer PE printed layers 1, between described polyamide PA protective layer 6 and polyethylene polymer PE safe floor 7, be provided with the second polyolefin A DMER adhesive-layer 5.Because the number of plies is too much therefore bonding by AD viscose glue, strengthen the connectivity robustness between a plastic sheeting.
Preferably, the thickness proportion of described polyethylene polymer PE printed layers 1, first polyolefin A DMER adhesive-layer 2, polyvinylchloride thermal insulation layer 3, ethylene-vinyl alcohol copolymer EVOH barrier layer 4, second polyolefin A DMER adhesive-layer 5, polyamide PA protective layer 6 and polyethylene polymer PE safe floor 7 is 2:1:2:2:2:1:2.
The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
