Sustainability continues to reshape packaging decisions across industries. One innovation gaining traction is mono-material packaging, a packaging solution designed entirely from a single type of material, such as 100% polyethylene (PE) or 100% polypropylene (PP).

Unlike multi-layer packaging, which combines different plastics, adhesives, or coatings, mono-material packaging uses only one material throughout. This design simplifies sorting, which in turn makes recycling much more efficient and results in a simpler, more cost-effective, and more environmentally responsible recycling process.

Why Mono-Material Packaging Matters Now

Traditionally, mono-material packaging has been most common in flexible packaging, such as pouches and films. However, sustainability regulations, brand commitments, and circular economy goals are pushing the industry toward wider adoption of mono-material solutions across all packaging levels, including tertiary packaging.

Marissa Lundberg, VP of National Accounts, Packaging and Sustainability at Group O, explains: "If it is multi-layer, it cannot be recycled easily. Everything is moving toward mono-materials."

That shift is now reaching the tertiary packaging space, where companies are exploring how the outermost packaging, which protects goods during storage and distribution, can be both effective and recyclable.

Mono-Materials in Tertiary Packaging

Tertiary packaging refers to materials used for bulk handling, transportation, and distribution. Examples include stretch film, shrink bundling film, strapping, dunnage, and edge protection. These materials play a critical role in stabilizing pallets, preventing damage, and ensuring products arrive safely.

Here is how mono-material innovation is showing up in tertiary packaging today:

 • Stretch Film: especially those made from 100% PE, are recyclable via store drop-off programs and specialized recovery systems. Film and flexible packaging comprise approximately 40% by weight of all residential plastics generated curbside (about 19,000 tons out of 47,298 tons), of which PE mono-material film alone accounted for 7,089 tons.
 • Shrink Bundling Film: Mono-material, polyethylene-based shrink films are being developed to replace multilayer films that often include non-recyclable components.
 • Strapping: PP and PET strapping are inherently mono-material and benefit from growing recycling infrastructure, making them easier to recover than mixed-material alternatives.
 • Dunnage and Void Fill: Air pillows made of 100% PE are fully recyclable, as are many foam replacements designed for bulk shipment protection.

Mono-Material Packaging Market Trends & Industry Growth

The global mono-material packaging market was valued at approximately USD 10.9 billion in 2024 and is expected to grow at an annual rate of about 6.4%, reaching USD 20.2 billion by 2034. Another report estimates a market value of USD 4.3 billion in 2024, growing to USD 7.2 billion by 2032 at a CAGR of 6.8%.

Notably, mono-material flexible packaging accounts for roughly 28–32% of the flexible packaging market and represents 35–40% of new packaging developments globally, with Europe leading adoption at 50–55% market presence.

The Path Ahead

While mono-material packaging is still most common in consumer-facing flexible items, tertiary packaging is quickly catching up. The drive toward recyclability and regulatory compliance means supply chains will increasingly prioritize materials that are easy to recycle, reduce landfill waste, and support circularity.

For companies managing large-scale distribution, tertiary packaging represents a major sustainability opportunity. Adopting mono-material solutions not only helps meet environmental targets but also aids compliance with emerging Extended Producer Responsibility (EPR) legislation, which favors recyclable, low-impact materials.

Mono Material Packaging: Not Just a Trend

Mono-material packaging is more than a trend; it is a strategic shift. For tertiary packaging, the transition toward single-material solutions ensures protective packaging does its job without creating recycling challenges downstream. From stretch film to strapping and beyond, mono-material innovation enables goods to be moved efficiently, safely, and sustainably.
