The science of plastic bottles
Plastic is a kind of have a fixed shape and intensity at room temperature, but has a plastic polymer materials at high temperature. Use the plasticity, plastic is made into various shapes and performance of packaging container. Plastic bottles with its lightweight, low cost advantage, become the main liquid packaging container on the market. With the widely application of the plastic bottles, the problem of recycling followed. How should we deal with waste plastic bottles? At the bottom of the plastic bottles have a end to end three arrow pattern, which represents the 'recycled recycling', but this is not the same as can be repeated use. Want to correctly use plastic bottle, the first to find out the main components of the plastic. Each take arrows are marked in the triangle number, the number 1 - 7 refer to the use of resin type, respectively. '1' PETE: ingredients are PET, polyethylene terephthalate glycol ester, commonly used in mineral water bottles, carbonated beverage bottle, etc. Its only heat-resisting temperature 70 ℃, if contact with hot liquids hazardous substances RongChu easily, and the distortion. Especially in 10 months after recycling, can release carcinogens. Note 1 PET plastic bottles don't with soy sauce and vinegar, also cannot hold high temperature water, otherwise it will cause health problems. '2' HDPE, HDPE on behalf of high-density polyethylene material, common in white bottle, cleaning supplies, bath products. Can be reused after careful cleaning in theory, but these containers are usually not good cleaning, residual original cleaning products is easy to become a hotbed of bacteria, not recycled. '3' PVC on behalf of polyvinyl chloride (PVC), commonly used in all kinds of building materials. Material plasticity is good, but the heat is easy to produce harmful substances, toxic substances along with food into the man's head after may cause diseases such as breast cancer, birth defects. '4' LDPE on behalf of low density polyethylene, can see such a mark in the plastic wrap on the food. Qualified plastic wrap in hot melt phenomenon occurs when temperature over 110 ℃, can leave some of the human body cannot decompose plastic preparation. Therefore, cannot be wrapped in plastic wrap food together in a microwave. '5' PP representative polypropylene, commonly used in microwave boxes. This material has low transparency, low temperature environment can be repeated use cleaning, melting point 167 ℃, can be in a microwave plastic box, can be reused after careful cleaning. '6' PS on behalf of polystyrene, used in snack box. Good chemical stability under 100 ℃. If contact with strong acid or alkali, will produce polystyrene, easy to cause cancer. '7' Others generally referred to as the PC other classes, often used in space cup, bottle. Such plastic containing bisphenol A, and produce controversy. Studies have shown that the higher the temperature the more release of bisphenol A, much sooner. In the use of plastic bottles, please see the bottom of the bottle, and use them in a suitable environment. At the same time, vigilance, do not use no logo, no recycling logo of plastic recycled products.
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.
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).
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.
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 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.
