The key to paper PLA straws lies in the efficient combination of polylactic acid (PLA) and paper materials. Changya has conducted in-depth research and development in this area to improve the durability of its products. As a bio-based, biodegradable thermoplastic, PLA exhibits excellent physical properties, including high strength and toughness. However, pure PLA straws are prone to softening in humid environments, which directly affects their performance. Therefore, Changya scientifically combines PLA with paper materials through accurate material ratio calculations, which not only retains the environmentally friendly properties of PLA, but also makes full use of the rigidity and hygroscopicity of paper materials, thereby significantly improving the durability of the straws. .
In order to further enhance the physical properties of straws, Changya continues to explore the application of new PLA materials. For example, the addition of nanofibers and bio-based reinforcements not only improves the strength and toughness of the straw, but also ensures its advantages in environmental protection properties. The application of these new materials makes paper PLA straws more durable and resistant to breakage while maintaining sustainable development.

Technological innovation: production technology and equipment upgrades
The modernization of production processes and equipment is a core factor in improving the durability of paper PLA straws. Changya New Material Technology Co., Ltd. uses advanced injection molding and blown film technology to ensure the stable physical properties of the straw during molding by precisely controlling parameters such as temperature, pressure and speed during the molding process. This technology not only improves production efficiency, but also achieves thinner wall thickness while maintaining high strength, thereby effectively reducing production costs.
To further improve the durability of the product, the company introduced multi-layer co-extrusion technology. Adding different materials to the different layers of the straw, such as a leak-proof material for the inner layer and a wear-resistant outer layer, gives the straw versatility. This multi-layer structure design ensures that the paper PLA straws are more durable on the basis of environmental protection properties and avoid the risk of deformation or breakage.

Quality control: strict testing and continuous improvement
Quality control is a guarantee mechanism to improve the durability of paper PLA straws. Changya New Material Technology Co., Ltd. implements strict inspection and testing at every step from raw materials entering the factory to finished products leaving the factory. The company has not only obtained international certifications such as BRC, GMP NSF, and ISO 22000, but also passed food safety tests such as LFGB and FDA to ensure the safety and reliability of its products.
At the same time, Changya New Material Technology Co., Ltd. has established a continuous improvement mechanism to continuously optimize product design and production processes by collecting customer feedback and market information. For example, in response to customer complaints that straws became soft after being soaked for a long time, the company developed a new waterproof coating technology that effectively improved the waterproof performance of straws. Through these measures, Changya New Material Technology Co., Ltd. not only improves the quality of its products, but also enhances customer satisfaction and market competitiveness.
