| Plastic material name | PLA raw material |
| Material grade | Injection molding, extrusion molding, food grade, |
PLA has the following characteristics and advantages:
Biodegradable: PLA is a biodegradable material that will be decomposed into carbon dioxide and water by microorganisms after decomposition, and will not cause long-term pollution to the environment.
Similar to traditional plastics: PLA is similar to traditional plastics in physical properties, with good toughness, mechanical strength and thermal stability.
High transparency: PLA has good transparency and is suitable for making transparent packaging materials.
Good processability: PLA can be made into products of various shapes through various processing methods such as injection molding, blow molding, and stretch molding.
Non-toxic and environmentally friendly: Since PLA uses natural plant raw materials and does not contain harmful substances, it is non-toxic and harmless to the human body and meets food-grade safety standards.
PLA has been widely used in various fields:
Food packaging: PLA can be used to make food packaging containers, tableware, fresh-keeping bags, etc., which can replace traditional plastic materials and reduce pollution to the environment.
Medical field: PLA can be used for medical devices, surgical instruments, sutures, etc. Due to its non-toxic and harmless characteristics, it is widely used in the medical field.
3D printing: PLA is one of the commonly used 3D printing materials, and can produce 3D printed products of various shapes.
Agricultural field: PLA can be used to make agricultural films, seedling trays, etc., which helps to improve the environmental protection and sustainability of agricultural production.
Other fields: In addition to the above application fields, PLA can also be used in textiles, daily necessities, electronic products and other fields.
