Printable environment-friendly credential card body

Abstract

The invention discloses a printable environment-friendly credential card body. The printable environment-friendly credential card body is characterized in that the printable environment-friendly credential card body is of a symmetrical composite layer structure, is formed in a hot-pressing way, and sequentially comprises a PET (polyethylene terephthalate) film heat transfer printing processing layer, a PET protective support layer, a PET esterification reaction layer, a PETG (polyethylene terephthalate glycol) connecting layer, a PETG printing layer, a PETG core material layer, a PETG printing layer, a PETG connecting layer, a PET esterification reaction layer, a PET protective support layer and a PET film heat transfer printing processing layer from top to bottom. The printable environment-friendly credential card body is reasonable in structure, easy to operate, environment-friendly, attractive in appearance and high in anti-counterfeiting performance, and credentials can be made and printed on the spot; the card body is high in firmness, high in physical and chemical stability and image accuracy and detail expression, and has good personalized printing effects; after the credentials are synthesized, the credentials have high wear resistance and durability, technical indexes of peeling, torsion, bending and the like completely meet legal credential making standards and requirements, and the potential safety hazard that personal information on the credentials is falsified and replaced is completely eradicated; and the card body has an actually adhesive-free card body structure, and is high in finished product ratio and environment-friendly.

Description

technical field [0001] The invention relates to a certificate card body, in particular to an environment-friendly certificate card body which can be printed on site. Background technique [0002] Due to the technical requirement that the layer structure of the national statutory certificate cannot be completely peeled off, the current international and domestic card bodies are usually PETG or PC card body materials with environmental protection characteristics, which are hot-pressed and laminated in a certain order. The personalization methods of its centralized certificate production are respectively printing personal visual information on the personalized printing film, then overall binding, secondary lamination card or laser etching card production, but due to the complicated process and expensive equipment, the production occupies a relatively large area. Large, unable to meet the increasingly prominent needs of on-site rapid issuance of certificates. [0003] On-site p...

The personalization methods of its centralized certificate production are respectively printing personal visual information on the personalized printing film, then overall binding, secondary lamination card or laser etching card production, but due to the complicated process and expensive equipment, the production occupies a relatively large area. Large, unable to meet the increasingly prominent needs of on-site rapid issuance of certificates

[0003] On-site personalized card issuance technology and equipment are mature both at home and abroad, but limited by the thermal transfer composite technology of PET card surface materials, the current on-site printed card body is basically PVC card body or ABS and PVC material composite The card body is prone to aging, cracking, breaking, easy to wear, etc. The stability of the card body, the peelability of the card making compound, and the adhesion of the heat transfer material basically cannot meet the requirements for the use of legal documents, and it is not suitable for documents, especially statutory documents. The application and promotion of certificates; at the same time, the PVC card body contains chlorine, which will produce a lot of toxic gases when burned, which is not an environmentally friendly material
