PLA color masterbatch: Jiangsu Meizilin Nanotechnology Co., Ltd. offers a biobased plastic coloring solution! 

Summer is full of vitality, and the application scenarios of degradable products are constantly expanding. Polylactic acid (PLA), as a bio-based material, has been more widely used in disposable tableware, packaging containers, 3D printing consumables, and other fields. However, the low processing temperature and heat sensitivity of PLA pose special requirements for colorants. The PLA colored masterbatch produced by Jiangsu Meizilin Nanotechnology Co., Ltd. provides targeted additives for the color presentation of PLA products. 

The PLA color masterbatch is made by using polylactic acid as the carrier and selecting pigments and dispersing aids that are compatible with PLA. It is produced through low-temperature melt extrusion and granulation. Since the processing temperature of PLA is usually between 170℃ and 210℃, exceeding this range may cause material degradation. Therefore, the pigments in the masterbatch need to be well dispersed within this temperature range and not undergo color changes. Jiangsu Meizilin selects a pigment system with matching heat resistance, avoiding the use of certain traditional pigments containing heavy metals, making the masterbatch more suitable for the environmental protection positioning of PLA. The product color spectrum covers conventional color series such as red, yellow, blue, green, black, and white, and can be customized according to customer color samples. 

During the summer, with high temperatures and humidity, PLA materials tend to absorb moisture, leading to hydrolysis during processing. The Meizilin PLA color masterbatch undergoes thorough drying treatment during production and is packaged with moisture-proof measures, which helps reduce the surface roughness or strength reduction of the products caused by moisture carried in the masterbatch. Each batch of products undergoes routine tests such as color difference, melt index, moisture content, and dispersion to ensure controllable color differences between batches. The enterprise can recommend appropriate addition ratios and carrier resin brands based on the processing methods of the customer (injection molding, extrusion, blown film, spinning) and the usage scenarios of the final products (food contact, outdoor display, etc.). 

Summer uses bio-materials, and coloring has a good solution. Jiangsu Meizilin Nanotechnology Co., Ltd. adopts standardized production processes and responsible quality control systems to provide durable PLA color masterbatches for the biobased plastic industry. Choosing Meizilin means that each PLA product will present clear and stable colors in the summer environment. 

Jiangsu Meizilin Nanotechnology Co., Ltd. is a technology-intensive nanomaterial manufacturing enterprise. It was jointly established by Shanghai Enxuanyuan New Materials Technology Co., Ltd. and Yancheng Ruizhe Color Masterbatch Co., Ltd., which holds the patent technology for wet grinding. The company focuses on the research and production of ultra-fine fiber coloring masterbatches for PET, PA, PP, PE, PLA, etc., and also provides technical solutions for functional fiber masterbatches.
