A label (as distinct from signage) is a piece of paper, plastic film, cloth, metal, or other material affixed to a container or product, on which is written or printed information or symbols about the product or item. Information printed directly on a container or article can also be considered labelling. Labels have many uses, including promotion and providing information on a product's origin, manufacturer (e.g., brand name), use, safety, shelf-life and disposal, some or all of which may be governed by legislation such as that for food in the UK or United States. Methods of production and attachment to packaging are many and various and may also be subject to internationally recognised standards. In many countries, hazardous products such as poisons or flammable liquids must have a warning label. Metal labels, also known as anti-metal electronic tags, metal-attached tags, and anti-metal tags, are special tags packaged with a special anti-metal and electromagnetic interference material and electronic tags. Non-metal-resistant electronic tags cannot be read by electronic tag readers when they encounter metal. According to the division of frequency bands, metal tags can be divided into: low-frequency electronic tags, medium and high-frequency electronic tags, ultra-high frequency and microwave electronic tags. According to the different characteristics of the application and the use environment, metal tags often use different packaging forms. The packaging forms generally include: card type, label type and special-shaped type.

From a texture point of view, most of the materials for making tags are paper, but also plastic and metal. In addition, new hang tags made of holographic anti-counterfeiting materials have also appeared. From the perspective of its shape, it is even more varied: there are long strips, half-folded, round, triangular, pocket-shaped and other special shapes, which are really colorful and dazzling.

PVC is the abbreviation of polyvinyl chloride. It is a polymer material and one of the largest general-purpose plastics in the world. It is widely used. Widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc. The main characteristics of PVC hang tags are high brightness, durability, flexibility and ready-to-stick properties, moisture resistance, UV resistance, aging resistance, chemical solvent resistance, etc.

Cord ends is an accessory product used to realize electrical connection, which is divided into the category of connector in industry. With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. In addition to PCB board terminals, the most widely used ones are metal cord ends, nut cord ends, spring cord ends and so on. The cord ends is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. There are screws for fastening or loosening, such as two wires, sometimes Need to connect, sometimes need to be disconnected, then you can use the terminal to connect them, and can be disconnected at any time, without having to solder or twist them together, very convenient and fast. And it is suitable for a large number of wire interconnections. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that enough current can pass.
