In the field of daily cosmetic tube and bottle packaging, with the improvement of technology, people have higher and higher requirements for cosmetic plastic bottles and plastic cosmetic tubes. As a fashionable consumer product, cosmetics not only rely on efficacy to open the market, but also need high-quality and high-tech cosmetic plastic bottles and plastic tube packaging materials to increase their value. As consumers' purchasing power increases, domestic cosmetics manufacturers are increasingly devoting their efforts to cosmetic packaging to attract consumers. The application of new plastic materials has gradually evolved into a way for the cosmetics industry to improve existing products and launch new products. Packaging development gradually highlights the characteristics of personalized display and innovation, the introduction and application of new technologies and processes, and the development and substitution of new environmentally friendly materials.

Plastics will continue to develop at a much faster rate than other packaging materials, because many of the characteristics of plastics cannot be replaced by any other packaging materials. While occupying the field of sales and packaging, the plastic packaging industry has developed into transport packaging, which will eventually force the "transportation packaging", which is still mainly metal, to be replaced by plastics.
Problems in the production of cosmetic plastic bottles and plastic cosmetic tubes
Problems in the production process of cosmetic plastic bottles and plastic tubes:

5. All cosmetic plastic bottles and plastic tubes are turbid (opaque) or all are whitish. Cosmetic plastic bottles and plastic tubes do not cool enough. The temperature here is too low, and the whitening is excessive stretching. Or the pre-blowing is too early, or the stretch rod is encountered. Search the gap between the tie rod head and the bottom mold; postpone the pre-blowing.
