The packaging industry is navigating a period of significant change. As environmental concerns gain prominence and expectations from consumers, regulators and investors evolve, interest in plant-based coatings is steadily increasing. This interest is not driven solely by ecological considerations—it reflects a broader assessment of risk, reputation, and long-term commercial sustainability. For senior leaders across the packaging value chain, engaging with this shift is not just a matter of technical awareness. It requires a willingness to reassess entrenched systems, anticipate regulatory change, and work collaboratively across departments and with external partners.
The case for plant based coatings
Traditional plastic packaging, which is primarily derived from fossil-based resources, is facing growing scrutiny. In response, plant-based coatings—developed from renewable materials such as starch, cellulose, proteins, and certain fungi—are being explored as a potential complement or alternative. These coatings are not a replacement for plastic itself, but rather a way of modifying packaging surfaces to deliver specific functional benefits, such as improved moisture or oxygen resistance, grease barriers, or compatibility with recycling and composting systems.
As recent industry analysis has pointed out, these coatings may allow converters and brands to maintain the performance of current packaging formats while addressing regulatory or consumer concerns. In some applications, they could enable packaging to become more widely recyclable or help remove certain petroleum-based additives. However, they are not a one-size-fits-all solution, and their technical capabilities vary significantly depending on the source material, application process, and end-use requirements.
Integrating plant-based coatings into packaging strategies is not a plug-and-play solution. It involves aligning innovation with business goals, understanding the constraints of supply chains, and assessing how new materials interact with existing infrastructure. It also means balancing environmental ambitions with commercial realities. Some coatings may be costlier or require different processing equipment, while others may present challenges in terms of shelf life, performance, or consumer perception.
For executives, the shift towards plant-based materials is as much a leadership issue as a technical one. While plant-based coatings offer genuine potential, their integration requires clear communication across teams, close engagement with suppliers, and an ability to weigh environmental benefit against practical feasibility. It also means engaging with evolving regulation—such as Extended Producer Responsibility schemes and plastic reduction targets—which may accelerate interest in materials that support recyclability or reduce dependence on fossil inputs.
This is not an area that can be tackled in isolation. Procurement must assess the viability of new supply sources; R&D teams need to test coatings under realistic conditions; marketing must convey benefits transparently and without overstatement; and sustainability teams must ensure that new materials genuinely improve environmental performance across the lifecycle.
Collaboration with innovators, research institutions and even competitors is often key to progress in this space. Many plant-based coatings are still emerging technologies, and scaling them often requires joint investment, shared learning, and practical feedback from the market. At the same time, constructive engagement with regulators can help shape standards that reflect real-world capabilities rather than idealised assumptions.
All of this points to the importance of leadership that understands complexity and is comfortable with change. Roles such as Heads of Packaging, Chief Sustainability Officers and ESG-focused procurement leaders have an important part to play—not necessarily in driving rapid adoption, but in ensuring that strategic decisions are made on a sound technical and commercial basis.
Plant-based coatings are not yet a standard feature of packaging operations, nor are they a silver bullet for sustainability challenges. But they represent a credible and growing area of interest that companies cannot afford to ignore. With the right expertise and the right leadership, these materials may offer both environmental value and competitive differentiation in the years to come.
