1. Pigment and dye additives
One of the anti-counterfeiting technologies recently invented by 樶 uses 'color changing' pigments. These additives contain multi-layer polymeric light-reflective coatings, which are coated around a reflective aluminum chip, so that the color of the plastic changes with the viewing angle. The color change, such as from red to green, is caused by the angle of the light waves reflected from different pigment layers. Color-changing pigments make plastic consumer products have remarkable aesthetic effects, and because these effects are not easy to be cloned, they also have anti-counterfeiting functions.
A method to identify whether plastic parts come from the original factory is to mix the cosmetic packaging material hose with pigments or dyes, and analyze the exposed parts and the ultraviolet region with a spectrometer. Those pigments or dyes will show unique patterns. Come. Even if the counterfeiters use extremely similar colors on their plastic products, they cannot obtain the same spectrum as the genuine product.
color-changing pigments can be mixed into a variety of resins, such as pc, pp, hdpe, pet, abs, thermoplastic pu, cellulose acetate and pa12. The weight ratio of the color-changing pigment in the resin is usually between 0.2% and 0.4%, and can be processed by standard processes such as injection molding, extrusion blow molding, thermoforming, calendering, film extrusion, and in-mold decoration.
2, particle logo
was originally developed to display the micro-marks to help track the source of explosives in the event of a *** event, but now it is widely used to track and distinguish the authenticity of plastic products. The typical particle markings are those that contain color bar patterns with specific distinguishing functions or polymer particles with special chemical components. These particles can be pre-mixed with thermoplastics before molding.
The marked particles are often pre-mixed with plastic powder, so that they can be used for molding or concentrated, and can be molded after being diluted during processing. The color bar micro-marks on plastic parts molded by injection molding, extrusion molding or rotational molding can be clearly distinguished by scanning with a microscope or pattern resolver. Some manufacturers make the logo fluorescent or magnetic, so that it can be easily distinguished by ultraviolet light or a magnetic scanner.
The diameter of particles is as small as less than 50 microns (equivalent to the size of a fennel), and the larger is about 600 microns (equivalent to the size of a salt particle). These particles are inert materials, usually do not react chemically, and can withstand the high temperature during molding without being damaged. By changing the number, model and color combination on each particle or changing the chemical properties of the particle surface, millions of unique coding mixtures can be produced. Because the resin contains coded particles, the manufacturer and product information can be distinguished with special code reading equipment.
