Description

Technical Field

[0001] The invention relates to the technical field of alkaline battery labels, in particular to a writable self-adhesive alkaline battery label. Background Art

[0002] As a common dry cell, alkaline zinc-manganese battery has a low self-discharge rate, can be stored for a long time and can be used when needed. When in use, it can work continuously with high current, provide stable working voltage and longer working time, have excellent discharge performance in high temperature environment and high working voltage under medium current discharge, have high safety performance, and rarely leak or explode in normal use. The manufacturing cost is relatively low, and the market demand is large, the production scale is large, and the price is cheap. As a supporting equipment for electronic equipment, it is widely used as a supporting power source for alarm clocks, radio-controlled aircraft models and sea models, power tools, electric toys, recorder remote controls, pagers, test meters, handheld walkie-talkies, instruments and other devices. With the development of society, people's living standards have improved, the quality of life has increased, and the awareness of high quality and environmental protection has become stronger and stronger. The high quality and environmental awareness index has also increased. People's demand for daily necessities is no longer to meet their living needs, but more attention will be paid to the quality, appearance, and quality and safety performance of the product during its use. Alkaline batteries use various types of self-adhesive labels to record the battery's own performance and production information and other related information, which are pasted on the outside of the battery to form a complete battery. However, in the prior art, traditional labels can meet daily use requirements, but the materials used to make most of the labels are not so environmentally friendly. Moreover, when users actually use the batteries, since the batteries have the same appearance, they are easily confused when they are stored together and then taken out, which brings confusion and trouble to users. Sometimes, due to the inability to distinguish and the fear of mixing batteries, they can only be thrown away, resulting in battery waste. Moreover, due to the smooth surface of the labels, users cannot record some information during actual use on the battery labels, which helps users to distinguish whether the batteries are used and the degree of battery use, prevent battery mixing and reduce battery installation time, and also helps after-sales battery analysis. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings and deficiencies of the prior art, the purpose of the present invention is to provide a writable self-adhesive alkaline battery label, on which a writable area is set, which solves the problem that the existing alkaline battery labels cannot be written, and the label meets the performance of alkaline battery labels.
