Sustainable Inks & Packaging: What the Food & Pharma Industry Must Know

The Cost of Progress? Not Anymore.

Every product label, every blister pack, every flexible pouch—has a story. But behind the eye-catching colors and tamper-proof packaging lies a hidden truth: traditional printing and packaging materials are damaging our planet.

In an era where climate change, consumer awareness, and strict global regulations dominate industry headlines, the food and pharmaceutical sectors face a pivotal choice. Do they continue with legacy packaging systems that are wasteful and hazardous—or pivot toward a more responsible, future-proof solution?

If you’re in the food or pharma business, this blog will unpack the urgent need for sustainable inks and packaging, the technologies leading the change, and how this shift isn’t just better for the environment—but better for your bottom line, too.

Why Sustainability Matters More Than Ever

From farm to fork, and lab to label—sustainability isn’t a buzzword anymore. It’s a requirement.

Today’s consumers are hyper-aware. They scan QR codes. They read the fine print. They care about carbon footprints, recyclability, and health compliance. And regulators? They’re tightening the screws. Governments across the globe, especially in Europe and North America, are enforcing sustainability standards around food safety, pharmaceutical compliance, and environmental impact.

Failing to comply isn’t just a bad look—it can mean fines, product recalls, and damaged brand trust.

The Real Impact of Conventional Inks & Packaging

Let’s be clear—most conventional inks are chemical-heavy, containing volatile organic compounds (VOCs), heavy metals, and petroleum derivatives. These toxins don’t just pollute air and water—they linger in packaging, potentially leaching into food or medicine if the barrier is compromised.

Likewise, plastic-based multilayer packaging is rarely recyclable and contributes significantly to landfill and marine waste. Worse, improper disposal in developing markets amplifies global ecological imbalance.

The question isn’t “Should we switch?”—it’s “How soon can we?”

Enter: Sustainable Inks – The Game Changer

What Are Sustainable Inks?

Sustainable inks are formulated with bio-based, renewable or non-toxic ingredients, reducing environmental harm and supporting circular production processes. Some of the most common include:

  • Water-based pigment inks
  • Vegetable or soy-based inks
  • UV-curable inks (low migration)
  • Compostable and biodegradable ink systems

But not all sustainable inks are created equal. For food and pharma sectors, compliance is non-negotiable.

What Makes Inks “Food & Pharma Safe”?

To be compliant, inks must meet strict international standards such as:

  • Nestlé Guidance Note on Packaging Inks
  • Swiss Ordinance on Materials and Articles (SR 817.023.21)
  • EU Framework Regulation (EC) No. 1935/2004
  • FDA 21 CFR Regulations

One standout option is water-based pigment ink technology, such as Memjet’s DuraFlex® systems, which comply with these health and safety guidelines. These inks offer vibrant color, high durability, and safety for indirect food contact packaging—making them ideal for flexible films, blister foils, cartons, and pouches.

The Shift to Eco-Friendly Packaging Materials

Switching to sustainable inks is just half the solution. Your packaging material matters just as much.

What Defines Sustainable Packaging?

To be considered sustainable, packaging should be:

  • Recyclable or compostable
  • Made from renewable sources
  • Lightweight yet protective
  • Compatible with sustainable ink systems

Common sustainable substrates include:

  • Recyclable films (PET, PP) with mono-material structure
  • Compostable cellulose-based films
  • Sugarcane paper or bagasse-based packaging
  • Bio-PE and PLA laminates

These digitally printable substrates that work seamlessly with water-based pigment inks, brands can reduce their carbon footprint without compromising print quality or compliance.

The Business Benefits Are Just as Big

Lower Inventory. Higher Customization.

Sustainable digital printing allows food and pharma brands to print short runs with no minimum order quantities. That means less waste, faster turnaround, and localized packaging.

Variable Data & Security Printing

From lot numbers to expiry dates to anti-counterfeiting QR codes—digital systems with sustainable inks can print variable data in a single pass. For the pharma industry, that’s a huge plus for compliance and patient safety.

Reduced Downtime and Faster Time-to-Market

With digital sustainable print systems, brands no longer need to wait weeks for offset plate setups or massive print runs. Instead, new SKUs, seasonal designs, and multilingual packs can be launched within days.

What Brands Should Look for in a Printing System

Making the switch to sustainable printing isn’t just about swapping out inks. It’s about choosing the right printing ecosystem.

Here’s a checklist:

Food- and Pharma-Safe Inks: Make sure they meet global compliance standards.
High Resolution: Look for systems offering 1600 x 1600 dpi for premium shelf appeal.
Speed & Versatility: At least 90 ft/min or higher for industrial-scale short-run jobs.
Modular & Scalable Design: So you can integrate inline varnishers, laminators, and slitters.
Compatible with Eco-Substrates: To ensure full packaging sustainability.

One such solution is the ArrowJet Aqua 330R, a sustainable digital pigment inkjet printer built specifically for food and pharma applications. It prints with Nestlé-compliant inks at blazing speeds and handles flexible packaging, cartons, and even blister foils.

Real-World Use Cases: Food & Pharma Going Green

Pharma Example: Blister Foil Printing with Compliance

A leading nutraceutical brand recently transitioned from solvent-based gravure printing to a digital water-based pigment ink system. The result?

  • Reduced production waste by 45%
  • Eliminated VOC emissions from the line
  • Achieved faster launches of new SKUs and formulations

Food Example: Flexible Pouches for Health Snacks

An organic snack company embraced sustainable inks and packaging for its on-the-go pouches. With short-run digital production, they now offer:

  • Custom labels per region and language
  • Seasonal limited-edition packs
  • 100% recyclable packaging without compromising on vibrant print quality

The Future is Circular—and You Should Be, Too

The linear model—take, make, waste—is obsolete.

The food and pharmaceutical industries are moving toward a circular economy. That means materials stay in use longer, waste becomes a resource, and consumers become co-creators in sustainability.

Brands adopting sustainable inks and digital packaging systems, does more than meet regulations—you build trust, credibility, and long-term resilience.

Final Thoughts: It’s Not Just Ink on Paper Anymore

Choosing the right ink and packaging material is no longer just a design or cost decision. It’s a strategic one.

For the food and pharma industries, sustainability is about more than optics. It’s about compliance, innovation, and responsibility. And with new-generation printing solutions now readily available, there are no more excuses.

If you’re still printing with VOC-laden inks or sitting on piles of outdated pre-printed packaging—it’s time for a change.

Print smarter. Pack greener. And future-proof your brand—one label at a time.
