How to identify the plastic raw materials
Cosmetics hoses, PP. PE. PA soft can bend, touching the hard wax sample, soapy, hitting a voice soft cutin, and PS. ABS。 电脑。 PMMA, no ductility, tapping sound is ringing. PP is approximately the same burning phenomenon and PE, there may be a small amount of black Yan, after the flame is extinguished, smell is between such as kerosene oil, non-toxic. 2. LDPE = = = soft rubber, high pressure low density polyethylene (HDPE = = = hard soft rubber, low-voltage high-density polyethylene VHDPE = = = super hard soft glue, super high pressure polyethylene light tenacity. Easy processing, good heat resistance, good low temperature toughness harder impervious, but good grinding, PE flammable, still can burn after away from the fire, burning flame under the yellow blue, black Yan rarely, in close to the flame, plastic melt dripping phenomenon, similar to the flow of the candle, after the flame is extinguished, has the obvious paraffin burning smell, non-toxic PE. Pp specific gravity less than water, float in water. Most of other plastic ratio greater than water, drowned in the water. 3. PC = = = bulletproof glue, polycarbonate colorless, transparent, and the impact strength of rubber, plastic, excellent electric properties, anti-aging, small shrinkage rate, dimension stability, PC combustion phenomenon near the PS but burning speed is slow, away from the fire will burn slowly and after flame yellow, with black Yan charcoal beam, melt foaming during burning, go out of the coma is flowers and smelly. 4. Organic glass (PMMA = = = The strength) Transparency, polymethyl methacrylate is wonderful, can be dyed various colors, very brittle crack, surface hardness, easy to wipe. The leakage resistance is good. PMMA and PS are transparent color, but different combustion condition, PMMA without carbon bundle of runaway, and it has the PS, PMMA combustion flame is the light blue, white at the top, melt foaming during burning, the unpleasant smell strong flowers and smelly and rotting vegetables and a badge. 5. PS = = = hard plastic ( Ordinary hard rubber) , polystyrene, transparent brittle crack HIPS = = = no broken gum, modified polystyrene, flexibility. High toughness and impact strength of ABS = = = ABS plastic,. Super don't glue, propylene - fine Butadiene - Styrene, easy to electroplating. High strength. Impact resistance, cold, grinding, corrosion. SAN( AS) = = = transparent no broken rubber, styrene - Propylene eyes copolymer EPS = = = plastic foam, polystyrene foamed PS primary color is transparent color, HIPS for ivory color, ABS color is light ivory color. PS. 臀部。 ABS is mainly: the difference between PS brittle, HIPS and ABS toughness is better. When bending specimen, PS is brittle crack, HIPS and ABS are hard to break, bending part pale. PS primary color is transparent color, HIPS for ivory color, ABS for shallow tooth-colored. PS. 臀部。 And ABS are flammable, take can still continue to burn after the fire, flame, yellow, and with black Yan charcoal beam, along with the Yan gas escape, PS less carbon beam, burns, near the flame of the surface of the plastic softening and less prone to drop, bubbles on the surface of PS and HIPS, ABS no bubbles and the coking status, this kinds of plastic dies from the smell of the difference is very big, PS with the single taste of styrene, ABS emit a pungent odor, have certain toxicity.
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.
How do small and medium-sized enterprises develop product of cosmetics.
1. Don’t make too many products. There are more and more small and medium-sized cosmetic manufacturers. Their products almost cover all kinds of cosmetics. You can see that there are many products, but in fact, they have many disadvantages. The first one is that the sales volume is not necessarily high. The 80/20 law states that 80% of the benefits of any entity come from 20% of the products, that is, 80% of the products can only contribute 20% of the benefits, which is not economic. The second one is that too many product lines are relatively backward in management, and their own strength is insufficient, enterprises can’t grasp the dynamics of consumers' hearts, so there are a lot of products which are not need by consumers. Third, most companies focus on speculation and bargain hunting. Too many product lines limit the development of an enterprise. It is difficult for consumers to form an understanding of the enterprise without a major product. And it is impossible to find the market position without the c
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).
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.
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.
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!
About D19 Vibration eye cream tube
Innovative and practical packaging materials not only greatly improve the manufacturing technology, but also have more advantages in practicality than traditional packaging materials. This is a high-tech eye cream hose, bringing the eye cream package into a brand new era.
Development of cosmetics to promote the development of tube packaging
With the rapid development of composite technology of plastics and different materials, composite tube gradually enters a variety of different packaging fields, such as high quality cosmetics, with its excellent water resistance, oxygen resistance and other properties and good convenience. This is changing the traditional concept of plastic composite tube packaging only for simple packaging of low-grade products.
What are the customers' concerns about cosmetic packaging enterprises
In the choice of cosmetics package enterprises, first of all to see whether the qualification of the enterprise is in line with the requirements of the national cosmetic package production. If the enterprise's qualification is blurred, it shows that the enterprise does not meet the national production requirements and the quality of the product can not be guaranteed. So when choosing cosmetic packaging enterprises, we must check the production qualification of enterprises.
What is the two in one tube and how to fill it in the rear? And the application of the product in skin care
Unlike a single branch tube, the most intuitive tube is a tube in the tube, which looks like a single branch, but can fill two kinds of material at the same time, at the same time extruding. When the material is not used, the material body is separated, and when used, mingling and merging.
