Introduction
In recent years, labels have become much more than a simple identifier. They now serve as a crucial bridge between brand storytelling, consumer trust, and environmental responsibility. From household goods to personal care and food packaging, the label is often the first thing a customer touches—and the last impression a brand leaves. As environmental regulations tighten and consumers demand greener packaging, the shrink sleeve printing industry is shifting toward solutions that are safer, cleaner, and more sustainable.
Among the most promising innovations driving this transformation are water-based inks and compostable films. Together, they represent a new chapter in sustainable printing—one where performance, aesthetics, and environmental responsibility coexist.
The Environmental Impact of Traditional Étiquette Printing
While traditional labels have served industries for decades, their production methods often carry an unseen environmental cost. Understanding these impacts helps explain why brands are switching to greener solutions.
Solvent-Based Inks and VOC Emissions
Conventional solvent-based inks release volatile organic compounds (VOCs) into the air during drying. According to the Environmental Protection Agency (EPA), the printing industry accounts for approximately 6–8% of global VOC emissions. These compounds contribute to air pollution and can cause long-term health effects. In contrast, water-based inks eliminate most VOCs, offering a cleaner and safer alternative for both workers and consumers.
Plastic Films and Non-Recyclable Laminates
Many older shrink sleeves are printed on PVC or PET films laminated with adhesives that make them difficult to recycle. This means that billions of discarded labels each year end up in landfills, contaminating recycling streams. The introduction of compostable and recyclable film options is helping to close this loop—an important step toward a circular packaging economy.
Water-Based Inks—Cleaner, Safer, and Smarter
Water-based inks are quickly becoming the gold standard in sustainable label printing. By using water as the primary solvent, they drastically reduce harmful emissions while maintaining print quality and versatility.
What Are Water-Based Inks?
Water-based inks consist of pigments, resins, and additives suspended in a water carrier. Unlike solvent inks, which rely on chemical evaporation, water-based systems use heat and airflow to dry the ink, minimizing environmental impact.
Core Advantages for Label Printing
- Reduced Emissions: Almost zero VOC release, supporting compliance with global environmental standards.
- Enhanced Print Quality: Vivid colors and high resolution suitable for both paper and film shrink sleeves.
- Versatilité: Works on a variety of substrates, including compostable films, paper, and foil.
Performance and Production Efficiency
Water-based inks have evolved significantly. Modern formulations offer faster drying times, better adhesion, and greater resistance to moisture and abrasion. According to a 2025 report from Smithers Pira, over 60% of packaging converters plan to adopt water-based systems within the next five years, citing improved sustainability and efficiency.
Compostable Films—Redefining Label Sustainability
Labels made with compostable films are a direct response to the growing call for eco-conscious packaging. These films decompose naturally under specific conditions, leaving no harmful residue behind.
Understanding Compostable Label Films
Compostable films are typically derived from renewable sources such as polylactic acid (PLA), cellulose, or starch blends. Unlike traditional plastics, they can break down completely in industrial composting facilities within 90–180 days, depending on material composition.
Benefits Compared to Conventional Films
- Lower Carbon Footprint: Derived from renewable materials, reducing dependence on fossil fuels.
- Compostability: Returns to nature without leaving microplastic pollution.
- Improved Brand Image: Helps brands demonstrate environmental commitment through verifiable action.
Limitations and Considerations
While compostable films offer major benefits, they require proper end-of-life handling. Not all waste facilities are equipped for composting, so education and labeling are crucial. For brands, combining these films with water-based inks creates an entirely sustainable shrink sleeve system.
Combining Water-Based Inks with Compostable Films
The Perfect Eco Pair for Modern Labels
When used together, these two technologies provide the ultimate balance of sustainability and performance. Labels printed with water-based inks on compostable substrates are non-toxic, low-emission, and visually striking—ideal for food, cosmetics, and household products.
Testing and Certification Elements
Before launch, brands should ensure compliance with recognized certifications such as
- OK Compost (TÜV Austria) – Verifies full biodegradability.
- EN 13432—Defines industrial compostability standards.
- FDA Compliance—Ensures safety for indirect food contact.
These certifications add transparency and consumer trust, key to maintaining credibility in an increasingly green-conscious market.
Comparing Label Printing Technologies
| Printing Technology | Ink Type | Durabilité | Rentabilité | Idéal pour |
|---|---|---|---|---|
| Flexographic Printing | Water-Based | Haut | Moyen | Large-volume labels |
| Digital Inkjet | UV/Hybrid | Modéré | Haut | Short runs, variable data |
| Gravure | Solvent-Based | Faible | Haut | Luxury finishes |
| Sérigraphie | UV/Water-Based | Modéré | Moyen | Specialty labels |
Analysis:
Flexographic printing with water-based inks remains the most sustainable and scalable solution for brands seeking both quality and eco-performance. Digital inkjet printing, on the other hand, offers flexibility for personalized or limited-edition products.
How Custom Label Solutions Empower Brands
Tailored Design and Functionality
Custom labels play a crucial role in product differentiation. With advanced materials and sustainable inks, brands can now design packaging that’s both functional and environmentally responsible. Common customization elements include:
- Waterproof and oil-resistant coatings.
- Matte or glossy finishes.
- Transparent or frosted looks for premium appeal.
- Embossed or tactile effects for sensory engagement.

FAQ
Are water-based inks suitable for all types of étiquettes?
They work well with most substrates, including paper and compostable films. However, testing is recommended for non-porous or specialty surfaces.
How long do compostable shrink sleeves take to degrade?
Typically 3–6 months under industrial composting conditions, depending on the material composition.
Can compostable shrink sleeves be used with plastic packaging?
Yes, but it’s best to ensure material compatibility and recyclability. Pairing compostable shrink sleeves with bioplastic packaging provides a fully sustainable option.
What’s the cost difference between eco-friendly and traditional shrink sleeves?
While sustainable materials can cost slightly more upfront, savings often emerge in compliance, brand perception, and long-term environmental responsibility.
How can I confirm my label materials are certified sustainable?
Look for certifications such as OK Compost, EN 13432, or FSC. Your packaging supplier should provide documentation verifying compliance.
