Description

Composite film, easy-to-tear cover with composite film and container with composite film

Technical Field

The utility model relates to an easily tear lid with NFC chip, concretely relates to complex film and be equipped with easily tearing lid and container of this complex film.

Background

Nowadays, the application of the internet of things technology to packaging is greatly developed, and the internet of things technology endows products with digital identities, so that the packaging has more traditional functions and becomes an information transmission medium. The system can provide optimization service for each consumer, and not only can improve the loyalty of the consumer, but also can improve the brand value. The ID technique commonly used at present gives every product sign indicating number, through in the product package the inside and outside digital code, bar code to and QR sign indicating number etc. are given, and the firm uses smart machine such as cell-phone to sweep the sign indicating number and realize networking and data exchange according to different application scene demands with the customer to can inquire, activity such as discernment and interaction. However, such codes mainly rely on digital and graphic recognition, and have the disadvantages of being reproducible, being capable of being shot and transferred, and the like, so that the potential risks of counterfeiting and other fraudulent activities exist in commodities. Near field communication is an emerging technology, devices using the NFC technology can exchange data when they are close to each other, and is integrated and evolved from a non-contact Radio Frequency Identification (RFID) and an interconnection and interworking technology, and by integrating functions of an induction card reader, an induction card and point-to-point communication on a single chip, applications such as mobile payment, electronic ticketing, door access, mobile identity recognition, anti-counterfeiting and the like are implemented by using a mobile terminal. The commodity with the NFC chip is required to be in contact with a commodity object, and corresponding information can be read. And the NFC chip can carry out encryption authentication design, and the link information of each touch identification can be effectively read only once, so that the link information cannot be copied and stolen. Therefore, the NFC chip is gradually gaining popularity in the merchandise sales management.

At present, a lot of high value-added goods are generally stored or accommodated in a packaging can, a cover body of the packaging can is generally made of an iron plate or an aluminum plate, a circle of score line is formed on the cover body, and the cover body is torn along the score line by pulling a pull ring on the cover body, so that the goods in the can body can be taken out. The cover body with the structure needs larger force to tear from the nick when being opened, the pull ring is easy to pull off, the opening is very inconvenient, the nick is sharper, and fingers are easy to scratch when the article in the can body is taken out. In addition, for these high-value-added articles, companies usually want to set anti-counterfeiting information or an interface for interactive marketing on the products to promote company publicity and increase the added value of the products, and the NFC chip is undoubtedly the best choice. However, signals of the NFC chip are easily shielded or interfered by metal in the using process, so that the NFC chip is usually arranged on the outer side of a can cover for a metal canned product, but the chip is easily stolen for illegal use and is easily damaged in the transportation process, so that information reading is abnormal; the NFC chip arranged on the inner side of the metal can cover is easy to contact with a product in the can body to pollute the product; even if the NFC chip is coated in metal, information reading is difficult due to metal interference, and therefore, the development of the NFC chip on canned products is also limited.
