The selection and quality of materials are the key to ensuring the quality of cosmetic hose packaging. The quality of the hose directly affects the processing and use of the hose. Plastic hose materials include polyethylene (for the body and head), polypropylene (cap), master batch, barrier resin, ink, varnish, etc. Therefore, the choice of any material will directly affect the quality of the hose. However, the choice of material also depends on factors such as hygiene requirements, barrier properties (oxygen resistance, water vapor resistance, fragrance retention, etc.), chemical resistance and other factors.

       As a convenient and economical packaging material, cosmetic tube packaging has been used in the daily chemical industry The field has been widely used and popularized. Good cosmetic tube packaging can not only protect the contents, but also improve the product level, thereby winning more consumers for daily chemical companies. So, for daily chemical companies, how to choose the right cosmetic tube packaging to suit their products? We will introduce from several important aspects.

  Cosmetic tube packaging

The choice of    lamp tube: First, the packaging materials of the cosmetic tube used should meet the relevant hygiene standards, and the harmful substances (such as heavy metals and fluorescent agents) should be controlled within the regulations Within range.

  

  The performance of barrier materials: Everyday chemical company’s cosmetic hose packaging contains products that are particularly sensitive to oxygen (such as certain whitening cosmetics) or volatile products (such as Essential oils or corrosive chemicals, such as certain oils, acids and salts). Use a five-layer co-extruded tube. Because the oxygen permeability of the five-layer co-extruded pipe (PE adhesive resin EVOH adhesive resin PE) is 0.2-1.2 units, while the oxygen permeability of ordinary PE single-layer pipes is 150-300 units. In a certain period of time, the weight loss rate of co-extruded pipes is dozens of times lower than that of single-layer pipes. In addition, EVOH is an ethylene-vinyl alcohol copolymer with excellent barrier properties and fragrance retention (preferably 15-20 microns in thickness).

  

   Material stiffness: Daily chemical companies have different requirements for the stiffness of cosmetic hose packaging. How to obtain the required stiffness? Density polyethylene, high density polyethylene and linear density polyethylene are commonly used for hoses. High density polyethylene (HDPE) has better stiffness than density polyethylene (LDPE), and the desired stiffness can be achieved by adjusting the ratio of HDPELDPE.

  

  Chemical resistance: HDPEcosmetic tube packaging has better chemical resistance than LDPE cosmetic tube packaging.
