Abstract

The invention discloses a durable film composite substrate for laminating card manufacturing and a manufacturing process. The composite substrate structurally comprises a printed layer, a connection layer, a film, a composite adhesive, a back adhesive A, a substrate sheet and a back adhesive B in sequence from top to bottom. The film can be one of a PET aluminum laminated film, a PET film, a PC film and a PETG film in thickness of 10-50micron; when the film is the PET aluminum laminated film, an aluminum laminated surface of the film is connected with the substrate sheet through the compositeadhesive and the back adhesive A; the substrate sheet can be one of PVC, PC, PETG and ABS in thickness of 80-800micron. The film composite substrate can be applied to the field of laminating card manufacturing; after laminating, initial 90-degree peel strength of the film and the substrate sheet reaches 12N / cm or above and still reach 9N / cm or above after aging for 14 days at 50 DEG C under the relative humidity of 93%, the substrate is superior to similar imported products in performance, and technical requirements on peel strength in international standards ISO7810, CQM and the like are completely met.

Description

technical field [0001] The invention belongs to the technical field of laminated cards, in particular to a durable film composite substrate for laminated cards and a manufacturing process. Background technique [0002] In recent years, the new card making materials with distinctive individual characteristics represented by laser card making substrates have received extensive attention from related enterprises at home and abroad. Laser card substrate is a kind of card material with laser appearance and anti-counterfeiting effect obtained by compounding laser film and plastic (usually PVC) sheet. Combination of card materials, used in the manufacture of financial cards, high-end VIP cards and various smart cards. However, at present, the US-imported laser card substrates that dominate the domestic market can only be printed by traditional methods such as offset printing, which cannot meet the requirements of digital printing. Moreover, the cards produced are aged at 50°C and ...
