To influence factors of cosmetic plastic products fade
On the market you can see the color of the various cosmetics bottles, do you know the manufacturer how difficult it is to overcome the challenge of cosmetic plastic bottle fade? In the production of cosmetics bottles will often meet products fade, there are many factors that can affect the cosmetic plastic bottle products fade, plastic belt color fading and pigments, light fastness of dye, the oxygen resistance, heat resistance, acid-proof alkaline, and the properties of resin used. In the production of color masterbatch on the required pigments, dyes, surfactants, dispersants, the performance of carrier resin and anti aging agent can choose after comprehensive evaluation, the following is a general factor influencing the production of cosmetic plastic bottle color. A. Acid-proof alkaline: color plastic products fade and chemical character of the colorant ( Acid and alkali, resistance to oxidation reducing) The relevant. Such as chromium molybdenum red resistance to dilute acid, but sensitive to alkali, cadmium yellow don't acid, these two pigments and phenolic resin for some colorants have strong reducing effect, the serious influence of colorant heat resistance, weather resistance and fade. 2. Heat resistance, thermal stability refers to the processing temperature of the paint pigment under heat, color change, the degree of fade. Inorganic pigment ingredients for metal oxides and salts, good thermal stability, high heat resistance. While organic compound paint under a certain temperature will occur the change of the molecular structure and a small amount of decomposition. Actually we need in the production process, if it is need high temperature heating plastic products, you need to choose more heat resistant properties of pigment, to ensure that the color change color, fade, ensure the overall appearance of the product. 3. Oxidation resistance: some organic pigments in the degradation of macromolecules in the aftermath of the oxidation or other changes, and gradually fade, the process is a process of high temperature oxidation, the second is in strong oxidizer ( Such as chromium Huang Zhong chromic acid group) The oxidation. Lake, after using azo pigment mixed with chrome yellow, red will gradually subside. Four. Light resistance, light fastness of the colorant directly affect the products fade, the glare of outdoor products, light (of the colorant used Fast) Level requirement is an important index, light level is poor, products in use will soon fade. So that is why the anti-glare board, such as highway water horse, etc. , in a few years later after the sun exposure will become light in color but generally in blow molding, will join quantitative resistance to UV components, to ensure the durability of the product color retention time.
Types and characteristics of cosmetic tube
Tubes are divided into single-layer, double-layer and five-layer tubes, which are different in anti-pressure, anti-penetration and hand feeling. For example, five-layer tube is divided into outer layer, inner layer and two bonding layer, and another barrier layer.
2018 Shanghai big Hongqiao fair, Guangzhou LISSON Plastic Co., Ltd. and you will be there
2018 the fair will again be strong in the Shanghai National Convention and Exhibition Center on 5.19-21 day, and Guangzhou LISSON Plastic Co., Ltd. will come to the same time. We will meet the exhibition with such products as non vibratory eye cream import instrument, double roller unique design hose and so on, and then lift the storm event of the whole industry chain!
The importance of cosmetic packaging
Cosmetics are necessaries of our life, but its mission to beautiful life makes it a opportunities which contains huge business. The consumer market should not be ignored, as the competition of cosmetics market is more and more fierce, each tube cosmetics businesses is aim for expanding their product sales, which have struggled to the cosmetics packaging and publicity.
Cosmetic tube field, where is the foothold in the future?
Nowadays, in order to meet the changing needs of consumers, whether it is basic skin care brands or efficacy brands, when most of them launch new series of products, they will launch matching products with instruments, aiming to realize the effective incorporation of brands through high-tech instruments.
What standard should cosmetic tube have in respect of oxygen resistance
Cosmetic tube as a container of cosmetics, do not react with the products is the most important function of tube, cosmetic ingredients are easy to cause the reproduction and growth of bacteria, in addition to its own factors, there is a part of the influencing factors because of the impact of oxygen and water; It can be seen that, the most important factor of cosmetic deterioration is oxygen, all cosmetic tube needs to have very good oxygen resistance and gas resistance (prevent the fragrance molecules in the cosmetics and the effective molecules of cosmetics overflow).
