Sustainable packaging must be environmentally friendly and degradable products added with plant fibers. Compared with other green materials, the technology is more mature, and 100% degradable, with a wide range of applications. In the future, it will be an important support for the green, circular and sustainable development of the economy.

The recycling rate of plastic is only 10%, which means that 90% of plastic is incinerated, landfilled or directly discarded into the natural environment.

In China, there is a tree with white flowers in early spring called magnolia. The white flowers on the tree can bring warmth and hope to people in spring. Magnolia has a special meaning. Its blooming does not show the mountain or dew, but only a faint fragrance, and the white and flawless petals are so pure that even the leaves are redundant, but it reveals an elegant and calm temperament.

Magnolia is also rich in volatile oil, which has certain medicinal value. Modern pharmacological research shows that Magnolia has inhibitory effect on common skin fungi. The spunlace non-woven fabric or mask cloth made of magnolia fiber is composed of organic chemical components, mainly including cellulose, lignin, hemicellulose, pectin, wax and other polymer components.

The antibacterial components in Magnolia fiber can destroy the structure of bacteria and make them "contact death", which is an efficient and safe physical method. Its antibacterial effect test shows that the bacteriostatic rate of Staphylococcus aureus, Escherichia coli and Candida albicans in the fabric made of 50% magnolia fiber in the spunlace nonwoven fabric reaches 91%, 82.6% and 86.7% respectively . At the same time, the fiber also has an anti-mite effect, and the repellency rate against mites is 87%.

Proyons high-strength white magnolia fiber is made of plant fiber, which can be granulated with environmentally friendly materials such as PLA to coexist with nature. At the same time, the overall strength and toughness of the fiber are further improved through the monofilament physical properties of PLA. Such fibers are more spinnable and easier to manufacture ultra-thin fabrics (22~25gsm). Make the mask cloth have better skin-adhesive performance to the skin.

The factors of liquid absorption performance are fabric thickness, degree of fiber entanglement, fiber composition and so on. In order to obtain a better application effect, the mask base fabric should absorb the essence to the maximum extent, and the liquid absorption capacity of the dry mask base fabric can be used to characterize the liquid absorption performance.
