A kind of production method of special enhanced printing base film for electronic label

Abstract

The invention discloses a production method of a special enhanced printing base film for an electronic label, comprising a PET resin slice, the PET resin slice is a high polymer with a hygroscopic tendency, and pre-crystallization must be carried out before biaxial stretching And drying treatment, improve the softening point of the polymer, avoid the resin particles from sticking to each other and agglomerating during the drying and melt extrusion process, remove the moisture in the resin, and prevent the polymer containing ester groups from hydrolytic degradation during the melt extrusion process and produce air bubbles. At present, most of the printed composite film base films are treated by corona treatment. The basic formula is adjusted on the production line, and 2 to 3 finalized formulas are determined. Based on imported pre-coated resin, formula debugging and process exploration are carried out. , give priority to the functional requirements of pre-coating, and realize small-batch production. On this basis, summarize the production experience, and gradually realize mass production, and there is a large market demand and good economic benefits.

Description

Technical field [0001] The present invention belongs to the field of special enhanced printing composite film technology, specifically a production method for special enhanced printing substrate film for electronic labels. Background [0002] China's printing-related industries are growing rapidly, the overall development of the industry is stable and orderly, at the same time, some subdivisions of the printing industry are also developing rapidly, and new industries and related industries are constantly subdivided. [0003] RFID is an abbreviation for Radio Frequency Identification. The principle is contactless data communication between the reader and the label to achieve the purpose of identifying the target. RFID products are widely used, typical applications are animal chips, automotive chip anti-theft devices, access control, parking lot control, production line automation, material management, etc., at the same time, it is also an important part of the Internet of Things s...

Problems solved by technology

With the rapid development of China's economy, various fields of electronic tags occupy a large proportion. Electronic tags seem simple, but in fact, the design and debugging are still relatively cumbersome. At present, it is not possible to form a one-step design, especially the design and coordination of special base films. Chips must go through multiple performance optimizations and adjustments, and each process link must be strictly controlled, so that the finished label can meet the design requirements and customer needs.
