Biodegradable Labels & Compostable Labels: Materials, Benefits & Options

As demand grows for eco-friendly and sustainable packaging, using biodegradable labels is transforming how businesses approach product labeling. With the eWhile “sustainability” provides the broad framework, many brands are now looking for specific end-of-life solutions like biodegradability and compostability. These materials are designed to return to the earth, but the technical requirements to achieve this—without compromising on print quality or shelf-life—are significant.

This post examines the science behind these materials and how to successfully integrate them into your product line.

What Are Biodegradable Labels?

A biodegradable label is constructed from materials that can be decomposed by bacteria, fungi, or other biological means. Most of these labels are derived from natural sources such as wood pulp, sugar cane, or corn starch (PLA).

It is important to note that biodegradability is a process, not a destination. The rate of breakdown depends heavily on the environment—temperature, moisture, and microbial activity all play a role. A label that is biodegradable in a forest may not be biodegradable in a dry landfill.

Biodegradable vs. Compostable Labels: Key Differences

This is the most frequent question we receive from clients. While all compostable materials are biodegradable, not all biodegradable materials are compostable.

• The Time Factor: Compostable labels must break down within a specific timeframe (usually 90–180 days) under industrial composting conditions.
  
• The Residue Factor: To be certified compostable, the material must leave behind only CO2, water, and biomass—zero toxic residue or microplastics.
  
• The Environment: “Compostable” typically refers to an industrial facility, though “Home Compostable” certifications are beginning to emerge for thinner paper-based stickers.
  

Compostable Stickers & Label Materials

Creating a compostable sticker is a multi-layer engineering challenge. For a label to be truly compostable, every component must meet the standard:

• Facestocks: Options include FSC-certified papers, cellulose films made from wood pulp, and PLA (polylactic acid) films made from fermented plant starch.
  
• Adhesives: This is the most difficult part. Most standard adhesives are synthetic polymers. You must specify a certified compostable adhesive that maintains its bond during the product’s life but yields to the composting process.
  
• Inks: While the volume of ink is small, using soy-based or water-based inks is often preferred to ensure the final compost is non-toxic.
  

Benefits of Switching to Biodegradable Labels

The primary benefit is the reduction of long-term plastic pollution, but there are clear business advantages as well:

• Alignment with Zero-Waste Initiatives: If your brand sells through zero-waste or organic grocers, compostable labeling is often a requirement for entry.
  
• Consumer Perception: Being able to provide clear disposal instructions (e.g., “Remove and compost this label”) creates a powerful emotional connection with the eco-conscious buyer.
  
• Regulatory Future-Proofing: With laws around “Extended Producer Responsibility” (EPR) tightening, brands that adopt circular materials now will face fewer hurdles in the coming years.
  

Industries Using Biodegradable & Compostable Labels

We see the highest adoption in industries where the primary packaging is also compostable or organic:

• Fresh Produce: Biodegradable stickers for individual fruits and vegetables ensure that the entire item can go into a compost bin.
  
• Cannabis & CBD: As a “plant-based” industry, these brands prioritize natural materials to match their brand ethos.
  
• Eco-Friendly Shipping: Subscription box companies are increasingly using compostable labels on their mailers to simplify the disposal process for the customer.
  

How to Source Biodegradable Labels for Your Products

When looking for a partner for custom label printing, the most important question is: “Can you provide the ASTM D6400 or EN 13432 certification for this specific construction?”.

At Royal Label, we help you navigate the trade-offs—such as moisture resistance versus compostability—to find a solution that protects your product while honoring your commitment to the planet. This deep dive into biodegradable options is just one part of a larger sustainable labeling strategy designed to help your brand thrive in 2026.
