Production method of special reinforced printing base film for electronic tag

Abstract

The invention discloses a production method of a special reinforced printing base film for an electronic tag. The production method comprises a PET resin slice, wherein the PET resin slice is a high polymer with moisture absorption tendency, the PET resin slice needs to be subjected to pre-crystallization and drying treatment before being subjected to two-way stretching, the softening point of thepolymer is increased, resin particles are prevented from being mutually adhered and caked in the drying and melt extrusion process, moisture in resin is removed, the polymer containing ester groups are prevented from being hydrolyzed and degraded and generating bubbles in the melt extrusion process, most of existing printing composite film base films adopt a corona treatment mode, a basic formulais adjusted on a production line, two or three shaping formulas are determined, formula debugging and process exploration are carried out on the basis of imported pre-coating resin, the functional requirements of a pre-coating layer are preferentially met, small-batch production is achieved, on the basis, production experience is summarized, batch production is achieved step by step, and large market requirements and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of a special reinforced printing composite base film, in particular to a production method of a special reinforced printing base film for electronic labels. Background technique [0002] my country's printing-related industries are growing rapidly, and the overall development of the industry is stable and orderly. At the same time, some sub-sectors of the printing industry are also developing rapidly, and new industries and related industries are constantly being subdivided. [0003] RFID is an acronym for Radio Frequency Identification. The principle is the non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID products are widely used. Typical applications include animal chips, car chip alarms, access control, parking lot control, production line automation, material management, etc. At the same time, it is also an important part of IoT sensing...

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.
