REDUCE ENERGY CONSUMPTION !
Packaging that pops with color while protecting the planet.
Reduce carbon footprint by 34–54% with Expanded Gamut Flexographic Printing.
At Ruey Chang, we believe that sustainable printing is more than a process — it’s a promise. Through the continuous adoption of advanced technologies and eco-friendly materials, we are committed to building a greener printing workflow that delivers both quality and environmental value to our clients.
In 2004, the United Nations Global Compact introduced the ESG framework — Environment, Social, and Governance — as a key benchmark for evaluating corporate sustainability. As industries around the world increasingly prioritize sustainable development, businesses must take responsibility for the environmental impact of their operations, including carbon reduction, climate action, energy conservation, and pollution control.
At Ruey Chang, we take this responsibility seriously. By adopting UV flexographic printing technology, a more environmentally friendly process, we significantly reduce carbon emissions throughout our production. This green transformation not only aligns with the ESG goals required by global brands and enterprises but also strengthens our appeal to socially responsible investors — enhancing our competitiveness in the international market.
At Ruey Chang, we are committed to implementing comprehensive eco-friendly strategies that align with the principles of sustainable development at every stage of our process.
Our 3R Environmental Commitment — Reduce, Recycle, Reuse — not only reflects our dedication to protecting the environment, but also represents the responsibility we uphold for our clients. Choosing Ruey Chang is a choice for a greener, more sustainable future.
Minimized Ink Usage:
UV inks have high concentration and color strength, allowing for reduced ink consumption compared to traditional inks.
Lower Energy Consumption:
UV curing technology enables instant ink drying, significantly cutting down drying time and energy use.
Reduced VOC Emissions:
UV inks are free of volatile organic compounds(VOCs), improving workplace safety and minimizing environmental pollution.
Less Waste Generation:
Streamlined production processes help minimize material waste, achieving efficient and responsible manufacturing.
Use of Recyclable Materials:
Printing substrates such as paper or mono-material films are selected for their recyclability.
Waste Sorting and Recycling:
A dedicated waste sorting system ensures proper separation and recycling of paper, plastic, and metal materials.
Partnerships with Recycling Providers:
Collaborating with professional recycling companies ensures waste is effectively reintroduced into the circular economy.
Reusable Printing Plates:
Flexographic printing plates are highly durable and can be reused multiple times.
Equipment Maintenance and Upgrades：
Regular maintenance and timely upgrades extend equipment lifespan and reduce the need for new resources.
We believe that every printing is a reflection of our hope for a better future.
Let’s move forward together—taking real action to support the environment, add a touch of green to our planet, and create a brighter, more sustainable tomorrow.
Packaging does more than protect—it communicates your brand and product story.
RueyChang pioneers the use of ECG (Expanded Color Gamut) in UV flexographic printing for flexible packaging. By covering a broader color range and enhancing color accuracy, we reduce ink usage and print waste—bringing both exceptional visual results and real environment-friendly production.
Reduce carbon footprint by 34–54% with Expanded Gamut Flexographic Printing.
Ruey Chang utilizes ASAHI water-wash plate technology combined with ESKO platemaking systems to reducing waste from the printing process.
The ASAHI water-wash system eliminates the need for harsh solvents, relying on water-based cleaning agents to significantly reduce wastewater and protect water resources.
Combined with ESKO’s CDI Crystal XPS for high-resolution imaging and consistent output, Ruey Chang strikes the perfect balance between sustainability, productivity, and print quality.
Our platemaking process achieves up to 41% energy savings.
Ruey Chang has introduced the BOBST M6 UV flexographic printing line, utilizing food-grade UV inks. During printing, the UV curing system instantly dries the ink under ultraviolet light without the need for volatile solvents, achieving zero VOC emissions. This ensures fast ink drying while significantly reducing air pollution.
Thanks to the low migration properties of food-grade UV flexographic inks, food safety risks are effectively minimized — safeguarding the health of consumers. The 10-color printing unit on this production line enhances color saturation and sharpness, and also supports varnishing and hot stamping, bringing packaging to life while remaining environmentally responsible.
Flexographic printing has 50% less GWP (Global Warming Potential) compared to traditional gravure printing
Moving beyond traditional solvent-based bonding, Ruey Chang embraces solventless lamination to enable truly green packaging.
Our UTECO Rainbow 4.0 solventless laminator minimizes chemical usage while enhancing production efficiency — striking the ideal balance between packaging consistency and environmental care.
Our solventless lamination reduces VOCs to near-zero and cuts energy use by 30–50%, delivering both environmental and energy-saving benefits.
