PLA masterbatch is a concentrated blend of PLA (Polylactic Acid) polymer with pigments and other additives, supplied as pellets, that is mixed into raw PLA plastic during the manufacturing process to impart desired colors and functional properties. It serves as a cost-effective and versatile way for manufacturers to customize PLA products for various applications, such as packaging, single-use items, and 3D printing, while enhancing their performance and sustainability.
What it is:
- A concentrated mixture of PLA polymer, pigments, and other functional additives.
- Supplied in pellet form for ease of use in plastic manufacturing processes.
How it works:
- The high-concentration masterbatch is mixed with natural, uncolored PLA pellets at a specific "let-down ratio".
- The process colors and modifies the PLA during manufacturing, which can include extrusion, injection molding, and 3D printing.
Why it's used:
- Coloration: To achieve specific desired colors for the final PLA product economically.
- Functional Enhancement: To improve properties like durability, moisture resistance (hydrolysis resistance), or to introduce fillers that reduce cost or alter performance.
- Customization: Allows manufacturers to tailor PLA-based products to meet precise requirements and market trends.
- Sustainability: Uses biodegradable PLA, aligning with eco-conscious manufacturing practices.
Common Applications:
- Packaging: Used in sustainable packaging materials and containers.
- Consumer Goods: Applied to products like toys and other single-use plastic items.
- 3D Printing: A crucial additive for coloring and improving the quality of 3D printer filaments.
- Automotive Parts: Provides a sustainable option for certain automotive components.
