Lu: su composite hose and plastic composite hose between the advantages and disadvantages of contrast

Lu: su composite rubber hose and plastic composite hose contrasts the advantages and disadvantages of all that is commonly used in cosmetics packaging plastic hose according to the materials and processing technology can be divided into lu: su composite hose, all plastic composite hose and plastic co-extrusion hose. 1. Lu: su composite hose aluminum-plastic composite tube is made of aluminum foil and plastic film co-extrusion molding, by the special tube machine processed into pipes of a container. Lu: su composite tube is mainly used for higher requirements for health and protection of beauty salons cosmetics packaging. Barrier layer, generally for the aluminum foil, the barrier layer depends on the size of the aluminum foil pinhole. With the continuous improvement of technology, lu: su composite hoses in the thickness of aluminum foil shield from 40 microns down to 12 microns or even 9 microns, greatly save the resources. Lu: su composite hose has the characteristics of high barrier property. Aluminum foil cover light, oxygen, water retaining the blocking performance. To prevent foreign materials into the salon cosmetics, to prevent the oxidation cosmetics, prevent cosmetics or spread through the hose, so as to guarantee the quality of beauty salons cosmetics. However, due to the use of aluminum foil, aluminum-plastic composite tube has many shortcomings, such as the content is not visible, environmental difference, springback is poor, the composite strength is lower than all plastic composite hoses, easy layering, etc. 2. All plastic composite plastic composite hoses hose are all made of plastic, plastic composite hoses can be divided into two types: full plastic block composite hoses and full plastic block composite hoses. Compared with aluminous model multiple tube, all plastic pipe has better environmental performance and convenient recycling. Better elasticity, to ensure that after extrusion cosmetics, hose can rapid restorable, always keep beautiful, the appearance of the normal. Due to the plastic composite technology, printing decoration can be diverse. According to need to choose the flexo printing size, can choose according to drawings complexity gravure, also can choose according to functional requirement surface or internal printing printing. According to the characteristics of the beauty salon cosmetics and the needs of different customers, all plastic composite tube can be made into different colors, such as colorless, transparent, transparent and opaque, give consumers a strong visual impact. But the disadvantage is that cheap cosmetics packaging usually adopts full plastic impede compound rubber hose, because the pipe side seam.
