Description
Technical field
The utility model belongs to the label material field, is specifically related to a kind of with temperature variation indicating label and application Polymer materialspreparation, that color is visual.
Background technology
The storage of fresh animal food, fruits and vegetables, biological products, special medicine and reagent etc., transportation have certain requirement to ambient temperature conditions.Such as the low temperature goods in long-distance transport, logistics, accumulating and delivery process, inevitably it temporarily need to be stored in the congealer (box) that dry ice, ice bag etc. provide, its contact environment temperature is judged intuitively or be monitored but following problem often affects the user:
(1) present, the nearly all logistics company warehouse of China does not have freezer, therefore when cold items (medicine, biological products) arrives in final user (perhaps consumer) hand, often dry ice occuring and ice bag all melts, can't know whether cold items exposes even lost efficacy.
(2) cold fresh food is in transportation, the refrigeration vehicle interior temperature does not reach guarantee the quality requirement or the interior temperature control of chill car of food, after reaching the destination, although article are stored in refrigerator, sold, the consumer does not also know that these article have exposed in fact or rotten.
(3) the special operation environment such as supply station panel box, cable often causes local overheating because of line fault, debugging or other reasons, thermal endurance is long may to be affected cable life or cause security incident if cross, and therefore need to carry out daily monitoring to specific installation, branch cable temperature.
(4) Special food such as cold fresh meat from the slaughterhouse to the refrigerator sales process of supermarket, very responsive to the variation of ambient temperature in storing and the logistics link.But meat is again extremely to hold putrefactive food, in surpassing the environment of room temperature, expose when surpassing more than 2 hours, increased the opportunities for contamination of the pathogenic bacteria such as salmonella, Listeria, Escherichia coli, and bacterial number increased by geometric progression every 30 minutes, so temperature is the key factor of the cold fresh meat shelf life of impact.At present China not yet forms complete Food Cold Chain system, because the Food Cold Chain technology is integrated not, the supporting assembling of product technology of storage and transport falls behind, and China is annual because of meat in storing putrid and deteriorated etc. impaired tens yuan.
Above four kinds of situations, all need to develop a kind of vision label that can be changed by low cost, safety, the eco-friendly indicated temperature that manufacturer, logistics company and final user accept, be affixed on article surface, if environment temperature is higher than the refrigerated storage temperature (perhaps environment temperature is higher than the acceptable temperature of article) of article needs, this label is with variation irreversible, color visual form indicated temperature.At present, although there has been commercial heat discoloration powder to sell on the market, the shortcoming of this heat discoloration powder is reversible.Therefore, manufacturing enterprise, logistics company and terminal user can the temperature sensitive label of acceptance must satisfy following requirement:
(1) makes production and the label printing of the required various raw materials of label not influenced by ambient temperature; Can operate under the room temperature.
(2) the finished product label finished of preparation occurrence temperature Quorum Sensing not in all logistics progresses such as storage, transportation only just begins to occur Quorum Sensing, " switch " of a temperature sense unlatching of labeling requirement when needs use.
(3) the temperature sense reaction is indicated by the visual mode of color, conveniently reads.
(4) because label in the future may be used as food service industry, so make the required various raw materials of label and be necessary for safely, environmentally friendly, avoid secondary pollution.
(5) with low cost, the essence of temperature sensitive label remains a label, the value of increase commodity that therefore should be not too high.
