Problems solved by technology

However, PETG resin particles have high density and chemical resistance, so it is difficult to obtain the wetting tension that meets the requirements of RFID label production.
[0013] During the production process of PETG printing sheets for RFID, a large amount of static electricity is likely to be generated, especially when producing materials with a thickness of less than 100 μm. Due to the light weight of the sheet itself, the sheet floats due to the electrostatic rejection effect, and it is difficult to stack when cutting. , causing accumulation, affecting product quality and output

Abstract

The invention belongs to the field of polyester resin, and discloses a PETG (Polyethylene Terephthalate Glycol) printing sheet for an RFID (radio frequency identification device) label and a manufacture process thereof. The PETG printing sheet for the RFID label comprises the following raw materials in parts by weight: 100 parts of GS2 type PETG resin, 10-20 parts of ADD2 type PETG resin, 10-15 parts of titanium white and 10-16 parts of nanoscale calcium carbonate. The product has low cost, high quality and high yield.

Description

technical field [0001] The invention belongs to the field of polyester resin, and relates to a modified polyethylene terephthalate (PETG) printing sheet used for RFID (Radio Frequency Identification, radio frequency identification) electronic tags and a manufacturing process thereof. Background technique [0002] This project cites the patent of Li Zhenbin's "PETG card base for resident ID card and its manufacturing process", the patent number is 200410041031.8. [0003] The PETG printing sheet for RFID tags is closely related to Li Zhenbin's patented technology of "PETG card base and manufacturing process for resident ID card". Both of them use PETG resin as the main raw material and adopt calendering process. However, since card making and label printing adopt different technical standards and production processes, the requirements for substrate technical indicators are also quite different. [0004] The second-generation resident ID card is composed of a printing layer, ...
