Problems solved by technology

[0003] The performance of the surface protective layer of the all-plastic laminated card is the key factor determining the performance of the card. The traditional full-plastic laminated card uses PVC material as the surface protective layer, and uses laminating glue to press the card core under high temperature and high pressure conditions. This kind of ordinary PVC surface protection layer is not printable and cannot be used to prepare personalized information cards
Although the traditional PVC surface layer is easy to be pressed with the core material, its solvent resistance, high temperature resistance, scratch resistance and UV resistance are not satisfactory, and it is difficult to meet the requirements of long service life in the field of making ID cards. PVC has a certain poisonous effect on the human body and the material will cause great pollution to the environment during production, long-term storage and destruction, so it is gradually being replaced by a new type of card mask that is more environmentally friendly and safe
[0004] For a long time, PET (polyethylene terephthalate) material has been considered as a substitute for PVC (polyvinyl chloride) material for its excellent temperature resistance, scratch resistance, aging resistance and many other advantages. The most ideal material for the card protection surface layer, but the printability of personalized identification information and the adhesion to the core material of the card have always been a difficult problem for people
Invention patent CN1526570A introduces an ink-absorbing coating layer coated on a PET (polyethylene terephthalate) sheet, and then uses an inkjet printer to print the required information. The ink-absorbing coating of this method The color fixation of the ink is not ideal, the printed information and images are often not clear enough due to ink diffusion, and the printing accuracy is not high, and the card mask made by this method is used for lamination or plastic sealing. The core material is pretreated with a binder, the process is relatively complicated, and the bond strength is not completely satisfactory
However, this product needs to use very expensive large-scale co-extrusion equipment, and the equipment investment is as high as tens of millions of dollars. At the same time, the production process is relatively complicated, and its product price is relatively high, which limits the scope and application of its products. Not widely used yet

Abstract

An environment protection type printable surface film for certificate card is composed of a surficial protecting layer (polyethanediol tere-phthalate (PET) film) and a functional printing-adhering layer containing special osmotic cross-linking assistant. Its advantages are high adhesion and transparency, and high print clearness.

Description

technical field [0001] The invention belongs to the field of card manufacturing, and in particular relates to an environment-friendly printable laminated card mask and a preparation method thereof. Background technique [0002] Traditional cards can be divided into hard paper cards, plastic-sealed cards and all-plastic laminated cards according to the material, structure, card pressing process and degree of informatization. Among them, hard paper cards and plastic-sealed cards are gradually being replaced by all-plastic laminated cards with better performance due to their easy damage, poor weather resistance and short service life. The core material and surface protection layer of all-plastic laminated cards are made of plastic materials, which are prepared by high-temperature lamination with special bonding materials. Combining barcodes, chips, magnetic stripes and other technologies, they are easy to read, beautiful, safe and durable. It can be used normally for several ye...
