Problems solved by technology

[0003] The purpose of this invention is to solve the technical problem of air pollution in the production process of existing printed labels or packaging products, to design a new way of expressing text and images on the surface of labels or packaging products, and to use specially designed microstructures to produce colors In contrast to the contrast, it can fully or partially replace ink printing to display the information of the packaged goods, and realize a green and environmentally friendly method of making packaging products without ink printing

Embodiment 1

[0047] Inkless printing self-adhesive label production: using ultra-precision CNC method, laser direct writing method, holographic exposure method, semiconductor photolithography method, plasma texturing method to obtain a microstructure relief metal mold, coated on the surface of PET film with high thermoplasticity Molecular resin layer with a thickness of 2μm to 4μm; vapor-deposited metal reflective layer with a thickness of 40nm to 100nm; the microstructure mold is transferred and formed on the PET coating surface by heating and nano-imprinting; the unnecessary metal reflective layer is etched by mask method Remove, reapply stickers, die-cut finished products, such as Image 6 shown.

Embodiment 2

[0049] Production of transfer-type inkless printing and packaging: first design and manufacture microstructure relief molds, and then coat easy-peelable thermoplastic coatings on the PET base film. The structure is embossed on the coating, and the metal film layer is partially evaporated; the microstructure surface obtained by embossing is bonded to the packaging printing substrate, and after drying, the PET base film is peeled off to complete the transfer of the microstructure, inkless packaging printing done see Figure 7 , PET can be reused by recycling the above process.

Embodiment 3

[0051] Composite inkless printing and packaging production: design and manufacture to obtain a microstructure relief mold, use corona, plasma, and coating methods on the surface of the PET film to obtain the surface dyne value treatment, and use UV glue on the microstructure mold and the PET treatment surface Composite, after UV curing, the PET and the microstructure mold are separated, and the microstructure displayed by the graphic is copied on the PET with the cured UV glue, and then the metal layer or transparent high-refractive index layer is evaporated to obtain the brightening of the graphic. Paste the vapor-deposited side of the obtained graphic film on the printing and packaging substrate, such as Figure 8 shown.

Abstract

The invention relates to the fields of printing and packaging, in particular to a manufacturing method of an ink-free printing label or package. According to the structure, black and white display and color display of words and images are achieved by utilizing diffraction, scattering, reflection, refraction and the wave guide phenomenon of guide which are generated by a microstructure. The microstructure is characterized in that speckles at specific rules and lines with composite periods are displayed as black and white comparison when the frequency is 10 micrometers-150 micrometers, are displayed as color diffraction images when the regular period frequency is 0.3 micrometer-10 micrometers and are displayed as three-dimensional images when the irregular period frequency is 1 micrometer-2 micrometers. According to the method, graphics and text information is converted into the microstructure structure design to be expressed, the printing label or the package can be molded at a time through mould copying, so technological links are reduced, the cost is lowered, and environment protection and low carbon can be achieved better; a traditional oil printing package can be updated and replaced by the ink-free printing package, and the ink-free printing package has the advantages of being environmentally friendly, scientific, fashionable, safe and resistant to fake and the like.

Description

[technical field] [0001] The invention relates to the field of printing and packaging, in particular to a method for making ink-free printing and packaging mainly used in food, electronics, cosmetics, medical and health care products, daily necessities, auto parts, tobacco and other hard or flexible packaging. [Background technique] [0002] Printing and packaging have always reflected the value of the packaged objects. Therefore, in the era of commodity economy, people pay great attention to product packaging and promote the prosperity and development of the commodity retail industry. Ink, diluent, dampening page, cleaning solution, the drying process produces a large amount of organic solvent volatilization (VOCS), which brings great air pollution. At the same time, the residual organic volatiles on the surface of printed packaging endanger the health of commodity consumers. Therefore, Europe and the United States have long included printing companies in the pollution emis...
