According to data and practice, there are many factors that affect the fading of plastic packaging bottles. The fading of plastic colored products is related to the light resistance, oxygen resistance, heat resistance, acid and alkali resistance and the characteristics of the resin used. In the production of color masterbatch, the required pigments, dyes, surfactants, dispersants, carrier resins and anti-aging additives can be selected after comprehensive evaluation of the above properties.

1. Distributors are divided into two types: tie-type and screw-type. In terms of function, they are divided into spray, foundation cream, lotion pump, aerosol valve, and vacuum bottle.

2. Types of blister products, mainly used in cosmetics include face masks, folding blister, bottom edge, turnover tray, half fold, bottom cover, three-fold blister.

3. The size range of the lotion pump is 16ml to 38ml, and the amount is 0.28ml/time-3.1ml/time. It is generally used for creams and washing products.

4. The bottle cap process can be used for electrochemical aluminum lettering, bronzing, and etching lines. There are matte and bright colors. Gaskets and inner caps must be used with pressure-sensitive sheets to enhance the sealing effect.

5. Hot stamping: A thin layer of paper is stamped on it. So there is no bumpy feel of silk screen printing. And do not heat directly on the two materials of PE and PP. Need to perform thermal transfer first and then hot stamping. Or a good bronzing paper can also be directly bronzed. Hot stamping is not allowed on aluminum plastic, hot stamping can be done at full speed.

There are many types of cosmetic containers, and the process is more complicated. Sometimes it is inevitable that there will be a gap between the container capacity and the design. Therefore, before the container is produced, the characteristics of the material should be fully considered and controlled in a targeted manner. Whether the special specifications are complete, whether the appearance is beautiful, whether the vision is comfortable, etc. Use an ultrasonic sealer or vacuum to observe the tightness of the heat-sealed edge of the flexible packaging bag.
