A good tube can not only protect the content, but also improve the product level, thereby winning more consumers for daily chemical companies. So, for daily chemical companies, how to choose high-quality plastic tubes to adapt to their products? We will introduce it from several important aspects.
The selection and quality of materials are the key to ensuring the quality of the tube, which directly affects the processing and final use of the tube. The material of plastic tube includes polyethylene (for pipe body and head), polypropylene (pipe cover), masterbatch, barrier resin, ink, varnish, etc. Therefore, the choice of any material will directly affect the quality of the tube. However, the choice of materials also depends on factors such as hygiene requirements, barrier properties (oxygen resistance, water vapor resistance, fragrance preservation, etc.), chemical resistance and other factors.
Tube selection: First of all, the materials used should meet the relevant sanitary standards, and harmful substances such as heavy metals and fluorescent agents should be controlled within the specified range.
