Why More Brands Are Switching to Biodegradable Packaging
Over the past few years working with flexible packaging suppliers and buyers, I've noticed that one topic appears in conversations far more often than it used to: sustainable packaging.
A few years ago, when companies discussed packaging projects, the questions were usually very practical. People asked about pricing, printing quality, lead times, or minimum order quantities. Environmental impact was sometimes mentioned, but it rarely became the main topic.
That situation has changed quite noticeably. Today, when a new client contacts a packaging manufacturer, one of the first questions is often something like: "Do you have biodegradable packaging options?"
This shift did not happen suddenly. It is the result of several things gradually coming together - environmental awareness, government regulations, and increasing pressure from consumers.
Plastic packaging is still dominant
To be fair, plastic packaging became popular for good reasons. It is lightweight, strong, and relatively inexpensive compared with many other materials. For food manufacturers especially, plastic films offer excellent protection against moisture and oxygen.
But the environmental impact of plastic waste has become harder to ignore. According to data from the United Nations Environment Programme (UNEP), global plastic production has exceeded 400 million tonnes annually, and packaging represents a large share of that total.
Most packaging is used only once before being discarded. That short life cycle is one of the reasons plastic packaging has become a major environmental discussion point worldwide.
Regulation is also playing a role. The European Union's Single-Use Plastics Directive, which took effect in 2021, aims to reduce certain disposable plastic products and encourage more sustainable alternatives.
Even companies operating outside Europe are paying attention, because global brands usually need packaging strategies that work across multiple markets.
What biodegradable packaging actually means in practice
When people hear the phrase "biodegradable packaging," they sometimes imagine packaging that simply disappears after being thrown away. In reality, the technology behind it is more complex.
Most flexible packaging products are built using multiple layers of materials. These layers are designed to protect the product from oxygen, moisture, and physical damage during transport and storage.
Because of that, biodegradable packaging solutions usually rely on specialized polymer materials rather than a single biodegradable plastic.
Two materials that often come up in industry discussions are PLA (polylactic acid) and PBAT (polybutylene adipate terephthalate).
PLA is produced from renewable agricultural sources such as corn or sugarcane. The production process converts plant sugars into lactic acid and then polymerizes it into a plastic-like material. PLA films tend to be relatively rigid and transparent, which makes them useful for certain types of packaging.
PBAT behaves quite differently. It is more flexible and has better elongation properties, which helps prevent films from becoming brittle. In many biodegradable film structures, PLA and PBAT are combined to balance strength and flexibility.
From a manufacturing perspective, these materials behave slightly differently from traditional plastics. Processing temperatures, sealing conditions, and film extrusion parameters sometimes need adjustment. Packaging converters usually spend quite a bit of time testing different material combinations before finalizing a structure.
Coffee packaging is one place where the change is visible
One interesting example I've seen is in the specialty coffee industry.
Many independent coffee roasters pay close attention to sustainability because it is closely connected to their brand identity. They often highlight ethical sourcing, relationships with farmers, and environmental responsibility.
Packaging naturally becomes part of that story.
Some coffee brands have started experimenting with compostable or biodegradable coffee bags made from plant-based films. These bags do not always match the barrier performance of traditional multilayer laminates yet, but they show how packaging innovation is gradually moving into real products.
For smaller brands, the packaging itself can communicate their values. When customers see a compostable coffee bag on a shelf, it reinforces the company's sustainability message.

Global brand attention
Major global brands are also looking at alternative packaging materials, although the process tends to move more slowly at large scale.

The company invests in recoverable projects
Nestlé, for example, has announced several initiatives aimed at reducing virgin plastic use in its packaging. The company has invested in research programs exploring recyclable and alternative packaging materials as part of its long-term sustainability goals.

Industry thinking on the application of packaging materials
Danone has also worked on improving the sustainability of packaging for its beverage and dairy products. Many of these projects focus on recyclability, but they reflect a broader industry effort to rethink packaging materials.
-
gradually replace
Even outside food and beverage sectors, companies are testing alternatives. Some e-commerce businesses have started using biodegradable mailer bags as replacements for conventional polyethylene shipping envelopes.
The challenges are still real
Despite growing interest, biodegradable packaging is not replacing traditional plastics overnight.
One challenge is barrier performance. Many packaged foods require strong protection against oxygen and moisture to maintain shelf life. Conventional plastic laminates are still very effective in this area.
Cost is another factor. Biodegradable polymers are usually more expensive than traditional plastics, particularly when production volumes are relatively small.
For this reason, companies often start with limited product lines when testing biodegradable packaging solutions.
The industry is clearly moving in a new direction
Even with these challenges, the overall direction of the packaging industry seems clear.
Ten years ago, biodegradable packaging was discussed mostly in niche sustainability forums. Today it appears in mainstream conversations between packaging suppliers, brand owners, and retailers.
Material scientists continue to improve biodegradable polymers, while packaging manufacturers experiment with new film structures and processing techniques.
From what I've seen in recent industry discussions, biodegradable packaging will probably not replace conventional plastic entirely. But it is becoming an increasingly important part of the broader effort to create more sustainable packaging systems.
And judging by how often clients are asking about it now, that conversation is only going to grow.
