Cosmetics packaging materials, general packaging materials in its main manufacturing process can be divided into: molding process, surface, and graphic processing process, assembly process trilogy.
Plastic color matching for colouring agent, it mainly divided into pigment (
Paint is the colorant can't dissolve in ordinary solvents, so to obtain ideal color performance, need to use methods such as mechanical heating mixed practice would paint evenly dispersed in plastic)
And dye.
1, inorganic pigments, good thermal stability, have very good weather resistance, good light stability, low prices, superior performance. For example, titanium dioxide, carbon black, etc.
2, organic pigments, high tinting strength, bright color, complete chromatography, the relative density of small, add a little. The disadvantage is that its heat resistance, weather resistance and covering power as inorganic pigments, poor dispersion effect, transparency, relative to the dye is poorer, and the price is higher. Mainly used for POM, PE, PP, TPU, TPE and other crystalline materials and some bright ( Dye brilliant degree cannot achieve the bright-coloured color of the product) Products in
3, dye, can be used in most organic solvents and dyeing plastic compounds, the density of the advantages of small, high tinting strength and good transparency. The disadvantage is that its average molecular structure is small, easy happening coloring when migration ( Crystalline materials) Compared with inorganic expensive, price and the price of organic pigments are close.
4, pearl pigment: also called mica titanium pearl pigment, is a kind of titanium dioxide coated mica chip. According to different color, can be divided into silvery white pearl pigment, rainbow pearl pigment, color pearl pigment three categories.
applications in cosmetics packaging, plastic color matching, is one of the major coloring process, because of its low cost, coloring and convenient way, users love deeply by the market. In packaging products, all kinds of bottle caps, pump head, bottles, such as lipstick tube technology, are used.
