Botongpack Bio-Ink Empowers Green Printing: Soybean-Based Ink Reshapes Packaging Industry Standards through Technological Innovation
Traditional petroleum-based inks have long posed persistent challenges of volatile organic compound (VOC) emissions, poor biodegradability, and environmental pollution. Against the backdrop of global low-carbon transformation, **soybean-based ink**—with renewable soybean oil as its core raw material—has triggered a technological revolution in the packaging printing industry.
As a green printing material certified by **80+ countries and regions**, it redefines the professional standards of eco-friendly packaging through **three core technical advantages**, integrating rigorous environmental performance, reliable safety guarantees, and superior printing quality.
-
● Core Material Innovation:
Takes refined soybean oil (bio-based content ≥75%) as the main binder, significantly reducing dependence on non-renewable fossil resources. Biological carbon content accounts for ≥60%.
-
● Quantifiable Environmental Benefits:
Achieves 90%+ biodegradation rate. VOC emissions are reduced by 50%-70% (≤100g/L).
-
● Recycling Enhancement:
Improves the deinking efficiency of recycled paper by 40% (deinking rate ≥92%), effectively solving the problem of ink residue and enabling closed-loop utilization.
-
★ Authoritative Certification Support:
Complies with international food contact material standards (FDA, EU, China GB). Passes strict toxicological tests, with **no detection** of benzene, toluene, xylene, or other harmful aromatic hydrocarbons.
-
★ Strict Harmful Substance Control:
Heavy metal limits (lead, cadmium, mercury, etc.) ≤10mg/kg. Migration amount of total organic carbon (TOC) ≤50mg/dm², meeting safety requirements for **direct contact** with food, pharmaceuticals, and infant products.
-
★ Low-Irritation Performance:
The ink system is free of formaldehyde and phthalates, with a smell intensity grade ≤2, ensuring a **safe production environment** and no potential health risks to end consumers.
-
✔ Superior Color Performance:
Color saturation is 20% higher than traditional inks. Color reproducibility ≥95%, presenting a bright and durable visual effect.
-
✔ Strong Printing Adaptability:
Compatible with flexographic, screen, and offset printing. Adheres firmly to various substrates, with adhesion grade ≥4B and resistance to friction ≥500 times.
-
✔ Verified Market Value:
Consumer preference rate for food packaging printed with soybean-based ink is **35% higher**, effectively enhancing brand trust and market competitiveness.
Widely Recognized Internationally
Included in the green procurement catalogs of multinational enterprises such as **Unilever, Nestlé, and P&G**.
Carbon Footprint Advantage
Each kilogram of soybean-based ink reduces carbon emissions by ≥2.3kg CO₂e. Certified by the U.S. Soybean Association (SBI).
Sustainable Development Concept
Promoting the packaging industry’s transformation towards **circular economy** and sustainable development.
Beyond a single product innovation, soybean-based ink represents a packaging philosophy of "coexistence with nature". It links the entire industrial chain from raw material extraction, production and printing, to packaging recycling.
