Problems solved by technology

However, due to the special performance requirements of printing, punching strength, folding and forming of metal packaging materials, it is difficult to meet the above performance requirements with the existing laser holographic plastic film and metal packaging materials.
In addition, the method of transferring the holographic pattern of the holographic laser film to the metal material first, and then printing requires the addition of special metal laser transfer equipment, which limits the application of laser holographic technology in this field

Abstract

The invention discloses a holographic laser printing transfer film and a production process for a metal package. The transfer film comprises a plastic substrate layer, a UV release layer, an information layer, an ink layer, an aluminum reflecting layer, a hot melt adhesive layer and a metal substrate layer which are superposed sequentially. According to the holographic laser printing transfer film of the above structure, the UV release layer, the information layer, the ink layer, the aluminum reflecting layer, the hot melt adhesive layer and the metal substrate layer are combined tightly and mutually and are all high in elongation, and cracks are avoided during composite stripping and punching forming. Compared with existing common metal printing package materials, the holographic laser printing transfer film has a holographic laser anti-counterfeiting function and high visual impact force, meets the requirements of the properties such as impact resistance, surface hardness, stretchability and heat resistance in aftertreatment, and meets the test requirement for the metal package in the subsequent machining procedure. In addition, according to the production process for the metal package, metal printing equipment is omitted, and the cost of a common metal package process is reduced significantly.

Description

technical field [0001] The invention relates to a holographic laser printing transfer film for metal packaging and a production process, belonging to the laser field. Background technique [0002] Metal packaging materials are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial product packaging, and ammunition packaging due to their good mechanical properties, excellent barrier properties, and decorative properties. Unlike paper and film packaging materials, which have mature anti-counterfeiting technology, metal packaging materials have very little anti-counterfeiting technology, and the phenomenon of counterfeiting is becoming more and more prominent. The main reason is that many anti-counterfeiting technologies (such as laser holographic anti-counterfeiting technology, two-dimensional code, etc.) are developed and applied for conventional packaging materials such as paper and film, and the supporting...
