Analysis of the advantages and disadvantages of three cosmetic hose materials

Commonly used plastic packaging materials are: PE, PP, ABS, PET and PVC, etc. Today, the editor will take you to a deeper understanding of the three materials used in cosmetic hose packaging: PE, PP and ABS. , PE material Polyethylene is insoluble in any organic solvents, but hydrocarbons and petroleum may cause polyethylene to swell. The embrittlement temperature of PE is generally below-℃, it has good cold resistance, small changes in mechanical properties at low temperatures, and excellent heat sealing, thermal adhesion and radiation resistance. PE is a non-polar polymer with poor printability, and its permeability to polar compounds is lower than that of non-polar compounds. Generally used for cosmetic packaging hoses and aluminum plastic tubes. , PP material polypropylene has excellent mechanical properties. PP is a non-polar material with poor printing performance. Its tensile strength, hardness, abrasion resistance, heat resistance and gas resistance are all higher than polyethylene. PP has good bending fatigue strength and is often used to make various bottle caps or connect plastic boxes. The chemical stability of polypropylene is good. It is resistant to acid, alkali, salt and a variety of organic solvents below ℃. It will not cause stress cracking in many solvents, detergents and detergents. PP has poor aging resistance, poor cold resistance, and brittleness at low temperatures. In the packaging of chemical products, PP is mainly used to make various hose caps. High safety, environmental protection, and recyclable. , ABS material ABS resin has almost no effect on water, inorganic salts, alkalis, and acids. It dissolves or forms an emulsion in ketones, aldehydes, esters and chlorinated hydrocarbons; it is insoluble in most alcohols and hydrocarbon solvents, but it will soften and swell after long-term contact with hydrocarbons. The corrosion of ABS resin surface by glacial alkyd, vegetable oil and other chemicals can also cause stress cracking, but it has little effect on non-stress products. It is widely used in electroplating outer covers of cosmetics.
