Abstract

The invention discloses a card protection film manufacturing process. The process comprises the following steps of: releasing a polyethylene terephthalate (PET) film by using an unreeling device; performing corona surface treatment by using a corona machine; performing curtain coating by using a curtain coating machine on one side of the corona machine to obtain an ethylene vinyl acetate (EVA) film; feeding the PET film which is subjected to corona surface treatment and the EVA film into a steel roller together, and performing extrusion compounding by using the steel roller and a grinding roller; feeding the film which is subjected to extrusion compounding into a mercury lamp box; and finally, reeling by using a reeling device. The surface of a card protection film manufactured by the manufacturing process is provided with a distinguishable pattern identifier; simultaneously, the identifier can automatically disappear in the subsequent over-plastic treatment process, and does not influence the appearance of a final product.

Description

A kind of manufacture craft of card-protecting film
Technical field
The present invention relates to a kind of manufacture craft of card-protecting film.
Background technology
In prior art, for conveniently recognized card-protecting film, need to be at card-protecting film surface printing pattern or other words identification, yet, this kind of mode can be brought a kind of bad result, in follow-up heat, cross and mould in processing, these patterns or word cannot disappear at all, affect the quality of product, for this reason, people be devoted to seek always a kind of can be false proof, conveniently recognized, a kind of technique that simultaneously identification pattern or mark can disappear in follow-up processing processing procedure.
Summary of the invention
The manufacture craft that the object of this invention is to provide a kind of card-protecting film.
The technical solution used in the present invention is:
A kind of manufacture craft of card-protecting film, comprise the following steps: unwinding device is emitted PET film, through corona machine Corona Surface Treatment, the casting machine curtain coating that is simultaneously positioned at corona machine one side goes out EVA film, the PET film of process Corona Surface Treatment sends into steel rider together with EVA film and sand roller is carried out extrusion cladding, film after extrusion cladding is sent in mercury lamp case again, finally by wrap-up rolling.
Sand roller is at EVA surface imprint pattern.
The surface of sand roller is in the not sandblast of part of EVA surface imprint pattern, remainder sandblast.
The invention has the beneficial effects as follows: there is cognizable pattern identification on the card-protecting film surface that manufacture craft of the present invention is made, be simultaneously thisly identified at follow-up mistake and mould in processing and can automatically disappear, do not affect final products outward appearance.
Accompanying drawing explanation
Fig. 1 is equipment of the present invention and manufacture craft schematic diagram.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is described:
embodiment 1:
As Fig. 1, a kind of manufacture craft of card-protecting film, comprise the following steps: unwinding device 1 is emitted PET film (unwinding device emit PET film speed be 1000-2200m/h), through corona machine 2 Corona Surface Treatment, casting machine 3 curtain coatings that are simultaneously positioned at corona machine 2 one sides go out EVA film (thickness of EVA film is 10-125 μ m), through the PET film of Corona Surface Treatment, send into steel rider 4 together with EVA film and carry out extrusion cladding with sand roller 5, film after extrusion cladding is sent in mercury lamp case 6 again, finally by wrap-up 7 rollings.
Due to surperficial figuratum not abrasive blasting of the part sand of sand roller 5, be light face, and remainder abrasive blasting sand, therefore, in the process that PET film and EVA film are extruded, sand roller 5 can impress out corresponding pattern on EVA film.
The object of Corona Surface Treatment is to make PET film surface coarsening, the PET film of surface coarsening and EVA film are when being pushed by steel rider 4 and sand roller 5, not sandblast of part due to the surface imprint pattern of sand roller 5, it is light face, remainder is sandblast, therefore,, when PET film and EVA film are extruded, sand roller 5 will impress out pattern identification on EVA film.
After steel rider 4 and sand roller 5 extruding, PET film and EVA film are combined with each other, and during then again through 6 heating of mercury lamp case, make the bond strength of two membranes larger.
The PET film and the EVA film that finally obtain are complex as an integral body, and meanwhile, EVA film surface is printed on pattern, in the time of application, moulded paper card directly to contact EVA film, heat is crossed when moulding, these patterns can melt and disappear, and therefore, do not affect the product appearance and the quality that finally obtain.
