Sales of Zhejiang Namei Materical Technology achieve good performance
Category: Green Manufacturing & Sustainability | Guide Introduction “Green color pastes” are everywhere in the market, and certification labels such as Blue Angel, Nordic Swan, EU Ecolabel and China Environmental Labeling are dazzling. But labels are not omnipotent, and the absence of a label does not mean not green. How to avoid being misled by […]
Color Paste Compatibility on Recyclable and Biodegradable Substrates
November 6, 2026
Category: Green Manufacturing & Sustainability | Technical Introduction Recycled plastics (rPET, rPP) and biodegradable materials (PLA, PBAT) are entering packaging and consumer goods in large quantities. But these substrates pose new challenges for color pastes: recycled materials have many impurities and poor compatibility—will color pastes affect recycling grades? Can biodegradable materials still degrade normally after […]
Category: Green Manufacturing & Sustainability | Technical Introduction Against the backdrop of carbon neutrality, “carbon footprint” has moved from concept into procurement lists. Many people think color pastes account for a small proportion and their carbon emissions can be ignored—but in fact, from pigment mining and chemical synthesis to dispersion grinding and long-distance transportation, the […]
Category: Green Manufacturing & Sustainability | Trend Introduction Environmental governance in coating and printing cannot bypass VOC. Solvent-based systems have pungent odors and restricted emissions, and waterborne conversion has become a clear direction. But many enterprises worry: will waterborne color pastes compromise performance or spike costs? In fact, low VOC and high performance can coexist—the […]
Category: Green Manufacturing & Sustainability | Technical Introduction The environmental friendliness of color paste manufacturing goes beyond “product waterborne conversion” to “clean manufacturing itself.” Pigment synthesis, grinding dispersion, and cleaning filtration all generate wastewater, waste gas and solid waste. Inadequate governance not only violates regulations but also backfires on your supply chain—if a supplier has […]
Category: Green Manufacturing & Sustainability | Compliance Introduction Once a color paste enters electronics, toys, food-contact or export products, environmental compliance shifts from a “bonus” to a “lifeline.” RoHS restricted substances, REACH registration and notification, EN71-3 migration limits, and FDA contact requirements—any single misstep can lead to the rejection or recall of an entire batch. […]
Cost Traps in Colorant Selection: The Hidden Price Behind Low Prices
October 30, 2026
Procurement & Supplier Selection | Pain Point “Buy from whoever is cheapest”—this is often the most expensive sentence in colorant procurement. Behind low prices often hide hidden costs such as unstable batches, excessive addition, and absent after-sales. Calculated into mass production yield and rework, total cost may exceed that of a more stable supplier with […]

EN71-3 Heavy Metal Control for Toy and Children’s Product Colorants
October 28, 2026
Compliance & Certification | Technical Application Children’s products are far more safety-sensitive than adult products. As the core of the EU Toy Safety Directive, EN71-3 limits the thresholds of migratable heavy metals in materials such as colorants, directly affecting children’s health. Many toy, stationery, and baby product companies fail on their first return shipment because […]
Compliance & Certification | Technical Application Is the color on food packaging safe? The answer is not in the word “waterborne,” but in food contact regulations. FDA (United States) and EC 1935/2004 (European Union) are the world’s two major food contact frameworks. They focus not on what the colorant “contains,” but on what it “migrates […]
