[0002] The anti -fake label of multilayer composite structure is a kind of high-performance label by the composite of multilayer different functional materials, is widely used in commodity anti -fake field.It usually includes transparent film, laser film, photochromic film, anti -fake ink layer and adhesive layer etc., by the organic combination of these materials, make label have complex and difficult to imitate anti -fake characteristic.For example, laser film can show stereoscopic visual effect, photochromic film can present different color under different light, and anti -fake ink layer contains invisible information or special texture.The anti -fake label of multilayer composite structure not only has excellent anti -fake performance, but also can play the role of protecting product, beautifying appearance, is widely used in medicine, food, cosmetics, high -end electronic product and bill etc.field.

[0003] The production of this kind of anti -fake label usually needs multiple precise processes to complete.Firstly, using continuous base film as carrier, and printing multiple anti -fake marks, such as two-dimensional code, microtext, holographic pattern etc.on film equidistantly.Then, the film with anti -fake mark and other functional film (such as photochromic film or laser film) are compounded together layer by layer through adhesive laminating process.Adhesive laminating process requires that each layer of material is completely attached, avoids offset or wrinkle, forms complete multilayer composite film structure.Finally, after cutting process, composite film is cut into single label, completes the final label finished product.However, due to the attachment of multiple materials in the compounding process, especially in the adhesive laminating stage, the flatness, flexibility difference of material surface and the uniformity of adhesive coating etc.factors, bubble is easily generated between film layers, directly affects the appearance, strength and anti -fake function of label.

[0004] Bubble problem is the main technical problem in the production of multilayer composite structure anti -fake label.Bubble not only causes label surface uneven, reduces its aesthetic property, but also can cause poor adhesion, affects actual service life.At the same time, for high-precision anti -fake label, the existence of bubble can destroy the anti -fake effect of label, affect the accurate reading and integrity of its information, in view of this, we propose anti -fake label laminating device without bubble.
