This Is The Principle That Invisible Of Plastic Bottle Prevents Bogus

Plastic bottle anti - counterfeiting technology, one of the use of "discoloration" pigment. These additives contain layers of polymerised light-reflecting coatings, which are coated around a reflective piece of aluminium chip to change the colour of the plastic depending on the Angle of view. Changes of colors, such as from red to green, are caused by the Angle of light waves reflected from different layers of paint. Discoloration pigment makes plastic bottles produce significant aesthetic effects, and because these effects are not easy to be cloned, so also has a function of anti-counterfeiting.

Color changing pigments can be mixed into different kinds of resins, such as pc, pp, hdpe, pet, abs, thermoplastic pu, cellulose acetate and pa12 and so on. The weight ratio of color-changing pigments in the resin is usually between 0.2% and 0.4%, which can be processed by standard processes by injection molding, extrusion blow molding, thermoforming, calendering, extrusion film and interior decoration.

Microdots are patterns of colour bars with specific resolution or polymerized particles containing specific chemicals that can be pre-mixed with thermoplastics before molding. The labeled particles are often pre-mixed with the plastic powder so that they can be used for molding or concentrated and then diluted during processing for molding. The microstrip identification on the plastic parts of injection molding, extrusion molding or roll molding can be clearly identified through the scanning of microscope or pattern resolution instrument.
