Silk is a natural protein fiber, mainly composed of silk fibroin and sericin. In addition to being a high-grade textile raw material, the comprehensive utilization of cosmetics, food and biomedicine has also been vigorously developed in recent years.
The comprehensive utilization of silk is basically a study of non-fibrous morphology, while the study of retained fiber morphology for paper and packaging industries is less. In 1997, Japanese scholars conducted silk papermaking tests, and the results showed that silk paper was soft and had excellent air permeability. The fiber structure of silk fibroin is often similar to that of plant fiber, and because of the unique properties of silk fibroin fiber, it theoretically gives paper a special property, so it can be processed through certain treatment.
After the silk is treated to a plant-like form for papermaking or plant fiber mating, the characteristics can be fully utilized as a high-grade functional packaging material.
Silk paper has good softness and breathability. If used in high-grade fruit packaging, it can increase its freshness. Silk paper also has good tensile strength and tear strength, so it is used for packaging of high-grade gifts and high-grade fruits. Can improve the grade of the product.
