Jiangsu Mizlion Nano Technology Co., Ltd PLA Color Masterbatch: An environmentally friendly coloring solution for bio-based materials!

PLA Color Masterbatch is a functional masterbatch specifically designed for coloring polylactic acid materials, composed of carefully selected eco-friendly pigments, PLA carriers and bio-based dispersants. This new type of colorant, through special formula design and processing technology, provides a safe and environmentally friendly color solution for biodegradable plastic products and is an important supporting material for promoting the development of the green plastic industry.

Technical features and formula design

The core technology of PLA color masterbatch lies in its compatibility with polylactic acid matrix and environmental safety. Due to the inherent biodegradability of PLA material, all components in the color masterbatch must comply with environmental protection standards. In terms of pigment selection, we strictly use environmentally friendly pigments free of heavy metals and azo dyes to ensure that the final products can pass relevant ecological certifications. The carrier uses modified polylactic acid with good compatibility with the PLA matrix to avoid affecting the degradation performance of the product due to compatibility issues.

In the design of the dispersion system, PLA colored masterbatch uses bio-based dispersants, and through molecular structure design, it achieves good compatibility with PLA carriers. Considering the thermal sensitivity of PLA material, the processing temperature range of masterbatch needs to be precisely controlled, usually between 150 and 180℃, to avoid material degradation due to excessively high temperatures. In addition, the pigment concentration needs to be precisely calculated to ensure the tinting strength without affecting the crystallization performance and degradation characteristics of the PLA material.

Performance advantages and application value

PLA Color Masterbatch has multiple performance advantages. Its environmental safety is outstanding, and all components comply with the standards for food contact materials and the requirements of eco-textiles. It has good color stability and can maintain the color as bright as before throughout the service life of PLA products. It has excellent biodegradability and will not hinder the degradation process of PLA materials. It has a wide range of processing adaptability and is suitable for various processing techniques such as injection molding, extrusion, and blown film.

These characteristics make PLA color masterbatches demonstrate significant value in multiple environmental protection fields. In the food packaging industry, provide safe coloring solutions for tableware, packaging films, etc. In the field of daily consumer goods, add aesthetic appeal to eco-friendly products; In terms of textile fibers, it provides environmentally friendly coloring for bio-based fibers; In the field of medical supplies, meet the labeling requirements for degradable medical devices.

Development trends and technological innovations
