Commonly used cosmetics packaging plastic hose and its characteristics: a

At present, the commonly used in cosmetics hoses plastic hose including lu: su composite hoses, all plastic composite hoses and multi-layer co-extrusion hose, they are able to meet the various needs of cosmetics packaging, such as health, barrier property, etc. 1. Lu: su composite hose lu: su composite hoses in aluminum foil and plastic film sheet made through co-extrusion composite technology, then through a special tube machine processed into tubular a packaging container, the typical structure of PE/PE + EAA + EAA/PE/AL/PE. Lu: su composite tube is mainly used for packing of health, high barrier property requirements of cosmetics, the barrier layer is commonly aluminum foil, and the barrier property depends on the aluminum foil pinhole degree. With the continuous improvement of technology, lu: su composite hoses in the thickness of aluminum foil blocking layer has been developed from the traditional 40 microns down to 12 microns, even 9 microns, greatly save the resources. Lu: su composite hoses in use process has the following advantages. （ 1) Aluminum foil with resistance, high barrier property, light, oxygen resistance and water resistance, barrier properties, on the one hand, to prevent foreign materials into internal cosmetics, to prevent the oxidation cosmetics, at the same time, also can prevent the moisture inside the cosmetics or composition such as essence through the hose spread to the outside world, so as to guarantee the quality of the cosmetics. （ 2) Low cost. To achieve the same cut off performance, lu: su composite hoses than all plastic composite hose and plastic extrusion hose materials, low cost, less economy better.
