图 2为图 1中 A-A线剖开的放大剖面图。 具体实施方式  Figure 2 is an enlarged cross-sectional view taken along line A-A of Figure 1. detailed description
如图 1所示， 所述新型保鲜铝箔 （膜） 1包括保鲜铝箔 （膜）基体 2和 设于保鲜铝箔 （膜）基体 2上的温度显示单元 3， 所述的温度显示单元 3可 以是感温材料， 所述的感温材料印制在所述的保鲜铝箔（膜）基体 2上， 二 者形成一个整体。所述的温度显示单元 3可以是多个，对应不同的温度数字。 所述温度数字范围可随意选择， 如温度数字范围可以是从一 20到 150， 每一 个整数温度数字对应一个温度显示单元 3， 那么需要 171个温度显示单元 3， 每一个温度显示单元 3显示一定范围的温度， 如温度显示单元 3显示的温度 数字是 20， 那么当环境温度是 19.5°C〜20.5°C (不包括 19.5Ό ) 时， 就可以 显示出温度数字 20， 消费者就可以知道新型保鲜铝箔 （膜） 1所包装的食品 或药品所处的温度是 20°C左右， 其他的温度显示单元 3显示方式类似。  As shown in FIG. 1, the novel fresh-keeping aluminum foil (film) 1 includes a fresh-keeping aluminum foil (film) substrate 2 and a temperature display unit 3 provided on the fresh-keeping aluminum foil (film) substrate 2, and the temperature display unit 3 may be a feeling The warm material is printed on the fresh-keeping aluminum foil (film) substrate 2, and the two are formed into one body. The temperature display unit 3 may be plural, corresponding to different temperature numbers. The temperature range can be arbitrarily selected. For example, the temperature range can be from 20 to 150, and each integer temperature number corresponds to one temperature display unit 3. Then, 171 temperature display units 3 are required, and each temperature display unit 3 displays a certain value. The temperature of the range, such as the temperature indicator displayed by the temperature display unit 3 is 20, then when the ambient temperature is 19.5 ° C ~ 20.5 ° C (excluding 19.5 Ό), the temperature number 20 can be displayed, and the consumer can know the new type. Fresh-keeping aluminum foil (film) 1 The temperature of the food or medicine packaged is about 20 °C, and the other temperature display unit 3 is displayed in a similar manner.
当然， 所述温度显示单元 3所显示的温度数字的范围可以缩小， 如一 15 到 70， 还可以更小如 10到 50。 当需要显示更确切的温度， 温度范围可以更 小， 使可以显示的温度数字精度增加， 如显示的温度范围为 20到 30， 所述 温度显示单元 3'可以显示的温度为 20、 20.5、 21、 21.5…… 30， 当然还可以 其他的温度数字显示方式。 Of course, the range of temperature numbers displayed by the temperature display unit 3 can be reduced, such as a 15 to 70, and can be as small as 10 to 50. When you need to display a more accurate temperature, the temperature range can be more Small, the temperature accuracy of the displayable temperature is increased. If the displayed temperature range is 20 to 30, the temperature display unit 3' can display temperatures of 20, 20.5, 21, 21.5, ... 30, of course, other temperatures are also possible. Digital display mode.
当对温度显示单元 3的温度显示精度要求不高时， 还可以以不同的颜色 标识来区别不同范围的环境温度， 如当温度范围为 10°C〜15°C时，对应该温 度范围的温度显示单元 3显示出红色， 当温度范围为 15T〜 20°C时， 对应该 温度范围的温度显示单元 3显示出绿色， 因此， 当所述新型保鲜铝箔（膜） 1 上的温度显示单元 3有红色显示时， 消费者就可以得知所述新型保鲜铝箔 (膜） 1所处的温度范围为 10°C〜15°C， 当所述新型保鲜铝箔 （膜） 1上的 温度显示单元 3有绿色显示时， 消费者就可以得知所述新型保鲜铝箔（膜） 1 所处的温度范围为 15°C〜20°C。 以次类推， 可以有很多种不同的温度显示方 式。  When the temperature display accuracy of the temperature display unit 3 is not high, different color ranges can be distinguished by different color indications, for example, when the temperature range is 10 ° C to 15 ° C, the temperature corresponding to the temperature range The display unit 3 displays red. When the temperature ranges from 15T to 20° C., the temperature display unit 3 corresponding to the temperature range displays green color. Therefore, when the temperature display unit 3 on the new type of fresh-keeping aluminum foil (film) 1 has When the red color is displayed, the consumer can know that the temperature of the fresh-keeping aluminum foil (film) 1 is in the range of 10 ° C to 15 ° C, when the temperature display unit 3 on the novel fresh-keeping aluminum foil (film) 1 has When the green color is displayed, the consumer can know that the new fresh-keeping aluminum foil (film) 1 is in a temperature range of 15 ° C to 20 ° C. By analogy, there are many different temperature display methods.
如图 2所示， 所述的温度显示单元 3的厚度与保鲜铝箔（膜）基体 2的 厚度相比， 几乎可以忽略。 当大批量生产新型保鲜铝箔（膜） 1 时， 卷材处 理过程就不会受到很大的影响， 保证了卷材的平整和良好的外观。 上面已经结合附图讨论了本实用新型实施例和具体实施方式， 应该理 解， 本实用新型并不局限于上述实施例和具体实施方式， 本领域的技术人员 在不脱离本实用新型权利要求限定范围内进行的各种变化均在本实用新型 的保护范围之内。  As shown in Fig. 2, the thickness of the temperature display unit 3 is almost negligible compared to the thickness of the fresh-keeping aluminum foil (film) substrate 2. When a new type of fresh-keeping aluminum foil (film) 1 is produced in large quantities, the coil processing process is not greatly affected, ensuring the flatness and good appearance of the coil. The embodiments and the specific embodiments of the present invention have been discussed above with reference to the accompanying drawings. It should be understood that the present invention is not limited to the foregoing embodiments and specific embodiments. Various changes made within the scope of the present invention are within the scope of the present invention.
