Abstract
The utility model provides a breathable film substrate humidity indicator, include film substrate and the fixed strengthening layer that is used for strengthening the fixed film substrate, it instructs regionally to be provided with a plurality of humidity on the film substrate, be provided with the sensitive coating of humidity in the humidity instruction region, the surface of film substrate still is provided with the waterproof micropore film of one deck. It is wide to prevent that the ventilative humidity indicator of static had a manufacturing cost of enterprise of reduction, resources are saved, display field, characteristics that the reaction is sensitive, the accuracy is high, can also avoid simultaneously with the direct contact of product, prevented that harmful substance in the sensitive coating of humidity is to the pollution of product.
Description
Technical field
This utility model relates to a kind of humidity indicating card, particularly a kind of breathable films base material humidity indicating card, is used for the moisture level detecting in the packing container of sealing.
Background technology
Humidity indicating card is the safety method of a kind of convenient and cheap detection ambient humidity, and user can judge rapidly the effect of the humidity in product packaging and desiccant by the color on card. If the humidity in packaging is than or equal to this humidity value, the corresponding point on card will become moisture absorption color from dry complexion changed, can learn the result of use of desiccant accordingly simply. At present, at some common on the market humidity indicating cards, processing technology is coarse, humidity sensitive coating in humidity indicating card oozes out, can not effectively prevent the leakage of hazardous chemicals in humidity sensitive coating, corrosion products, and all adopt papery water suction base material, single use, recovery utilization rate is low again. Simultaneously adopt paper material as base material time, inadequate environmental protection and recycling rate of waterused is low, liquid drips to the dispersion easily causing liquid on base material, affects the result of use of humidity indicating card. Additionally, the humidity indicating card of paper substrates is mostly single use, uneconomical saving, there is certain limitation the environmental area used, if so used in a large number, environment can be caused certain pollution, and effect is undesirable.
Summary of the invention
In order to overcome deficiency of the prior art, this utility model provides a kind of breathable films base material humidity indicating card, employing water absorbing capacity is weaker than the materials such as the nylon of paper substrates and makes film substrate, one layer of fixing strengthening layer of compound below film substrate again, it is therefore prevented that the shortcoming affecting result of use due to film substrate deformation. A kind of breathable films base material humidity indicating card that this utility model provides, compared to existing paper substrates humidity indicating card, fixing strengthening layer is unlikely to deform, recoverable rate is high, save resource, fixed the harmful substance that strengthening layer can also intercept in humidity sensitive coating simultaneously, through film substrate, product is caused erosion. By the one layer of waterproof microporous membrane of surface recombination at film substrate, it is possible to prevent liquid water penetration, but the moisture contained in air will not be stoped to pass through, thus effectively isolation humidity sensitive coating contacts with the direct of product, it is prevented that product is polluted by humidity sensitive coating.
This utility model is adopted following technological means to solve its technical problem.
A kind of breathable films base material humidity indicating card, including film substrate with for strengthening the fixing strengthening layer of fixing film substrate, described film substrate is provided with multiple humidity indicating area, being provided with humidity sensitive coating in described humidity indicating area, the surface of described film substrate is additionally provided with one layer of waterproof microporous membrane.
Further, described film substrate is that nylon, polyacrylamide, polyacrylic acid, polysulfonate polyvinyl alcohol, cellulose, starch, poly-polysaccharide, polyoxyethylene or other water absorbing capacity are weaker than the material of paper substrates and make.
Further, described fixing strengthening layer is polyphenylene sulfide, polypropylene, nylon, PE plastics, CPP plastics, PET, CPP plastics, PMMA plastics, PC plastics, PET, PBT plastic or BOPP plastic material.
This utility model have the beneficial effect that this utility model provide a kind of breathable films base material humidity indicating card there is reduction enterprise production cost, economize on resources, indication range wide, be quick on the draw, feature that degree of accuracy is high, can also avoid contacting with the direct of product, it is therefore prevented that the pollution to product of the harmful substance in humidity sensitive coating simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is sectional view of the present utility model.
In figure: 1-film substrate; 11-humidity indicating area; 2-humidity sensitive coating; 3-fixes strengthening layer; 4-waterproof microporous membrane.
Detailed description of the invention
In order to make this utility model be solved the technical problem that, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, does not limit this utility model.
Shown in seeing figures.1.and.2, this utility model provides a kind of breathable films base material humidity indicating card, including film substrate 1 with for strengthening the fixing strengthening layer 3 of fixing film substrate 1, described film substrate 1 is provided with multiple humidity indicating area 11, being provided with humidity sensitive coating 2 in described humidity indicating area, the surface of described film substrate 1 is additionally provided with one layer of waterproof microporous membrane 4.
Wherein, the shape of described viewing area 11, number and position can be configured as required. It is weaker than, by the nylon material or other water absorbing capacity that water absorbing capacity is weaker than paper substrates, the film substrate 1 that the material of paper substrates makes and replaces original paper substrates, the fixing strengthening layer 3 of compound one strata diphenyl sulfide or polypropylene material below film substrate 1 again, prevent the shortcoming affecting result of use owing to film substrate 1 deforms, fix the harmful substance that strengthening layer 3 can also intercept in humidity sensitive coating 2 simultaneously, through film substrate 1, product is caused erosion.
By the one layer of waterproof microporous membrane 4 of surface recombination at film substrate 1, it is possible to prevent liquid water penetration, but the moisture contained in air will not be stoped to pass through, thus effectively isolation humidity sensitive coating 2 contacts with the direct of product, it is prevented that product is polluted by humidity sensitive coating 2.
In actual use, as long as humidity indicating card being placed directly on the product instrument that need to test, existence due to fixing strengthening layer 3 and waterproof microporous membrane 4, completely avoid the direct contact product instrument of humidity sensitive coating 2, effectively prevent the pollution to product of the harmful substance in humidity sensitive coating.A kind of breathable films base material humidity indicating card that this utility model provides has reduction enterprise production cost, economizes on resources, indication range is wide, be quick on the draw, feature that degree of accuracy is high, can also avoid contacting with the direct of product, it is therefore prevented that the pollution to product of the harmful substance in humidity sensitive coating 2 simultaneously.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendments done within spirit of the present utility model and principle, equivalent replacement etc., should be included within protection domain of the present utility model.
