According to the classification of product properties, bio-based materials can be divided into bio-based polymers, bio-based plastics, bio-based fibers, bio-based rubbers, bio-based coatings, bio-based material additives, bio-based composites, and products made from various types of bio-based materials. Among them, bio-based biodegradable materials have the characteristics of green, environmentally friendly, renewable raw materials and biodegradable that traditional petroleum-based plastics and other polymer materials do not have; bio-based fibers have been widely used in fashion, home, outdoor and industrial fields, and are gradually moving towards the industrial scale of practical application and industrialization; bio-based plastic products in packaging materials, disposable tableware and shopping bags, baby diapers, agricultural films, textile materials and other fields have gained a lot of popularity. Bio-based plastic products are well applied in packaging materials, disposable tableware and shopping bags, baby diapers, agricultural films, textile materials and other fields, and are generally recognized and accepted by the market.
