AI Technical Summary

Technical Problem

The traditional humidity display card is a disposable tool, which is troublesome to operate and is inconvenient to record humidity detection information for different time periods in the previous sealed packaging, resulting in inconvenient viewing of humidity information.

Method used

A humidity indicator card with a protective film is designed, with multiple built-in humidity cards, which are encapsulated by an isolation protective film. Each humidity card is packaged separately. The isolation protective film is covered by a heat sealing process. It is isolated and separated by a sealed isolation clip and a protective film separator to achieve single use and multiple reuse of the humidity card.

Benefits of technology

It realizes multiple reuse of the humidity card, which is convenient to record the humidity information inside the sealed container during different time periods, facilitates later statistics and calculation work, and avoids leakage and influence of the edge isolation protective film of the humidity card.

Abstract

The utility model provides a humidity indicator card with a protective film, which relates to the technical field of humidity indicator cards and comprises an indicator card carrier plate, a mark sticker is adhered to the right edge of the upper surface of the indicator card carrier plate, a humidity card is arranged on the upper surface of the indicator card carrier plate, and the upper surface of the indicator card carrier plate is covered with an isolation protective film through a heat sealing process. According to the humidity display card, a plurality of humidity cards are arranged in the humidity display card, the humidity display card is packaged through an isolation protection film, humidity information in a sealed container in different time periods can be recorded through the single indicator card carrier plate, and the humidity display card can be used for displaying humidity information in the sealed container in different time periods. The humidity display card is convenient for later statistics and calculation work, and solves the problems that an old humidity indicator card needs to be taken out, discarded and replaced with a new humidity indicator card every time a package is opened and sealed again, and humidity detection information in different time periods in the sealed package is inconvenient to record.
