Your Next Baking Paper Might Be Made From Potatoes, Not Petroleum

Potato starch has been a food-industry workhorse for decades — the thing that thickens a sauce or binds a processed snack. What gets far less attention is that the same molecular properties making it useful in food are now the basis of a real, commercially deployed industrial materials category: bioplastic and biodegradable packaging film.

The starch-based bioplastics market was valued at approximately USD 588 million in 2025, and is projected to reach USD 758.27 million by 2032 — a compound annual growth rate of roughly 3.7%. Zoomed out to the full bioplastics category, global production capacity reached about 2.47 million tonnes in 2024, with actual output estimated at 1.44 million tonnes. Packaging is comfortably the largest single application, at 43% of the market in 2023, with that share projected to climb to 48% by 2028 — meaning the growth curve for this entire category is being driven substantially by exactly the kind of film and barrier applications potato starch is well suited for.

Corn starch remains the dominant bioplastic feedstock, accounting for nearly half of all starch-based bioplastic production, mostly on the strength of abundance, cost, and ease of large-scale processing. Potato starch occupies a smaller but genuinely distinct niche — valued specifically for its high amylose content, the linear (rather than branched) form of starch molecule, which produces stronger, more flexible, more transparent films than starches lower in amylose. This isn't a new or separate chemistry discovered for industrial purposes — it's the exact same gelling and film-forming behavior that makes potato starch useful in food applications, extended into a materials-science context.

Royal Avebe, headquartered in Veendam, the Netherlands, and operating since 1919, is one of the world's major potato starch and potato protein ingredient suppliers, with sales offices spanning the US, Europe, and Asia. Its Perfectafilm™ line is a modified industrial starch made from non-GMO, food-grade potato starch, used across paper and packaging applications to reduce porosity, control dust, improve printability, and boost barrier performance in the finished product.

What makes Perfectafilm™ a genuine commercial product rather than a lab curiosity: it offers superior film formation, high stability in solution, a transparent, colorless appearance, and strong binding properties compatible with multiple binder systems — and it meets FDA and BfR (Germany's Federal Institute for Risk Assessment) guidelines for direct food contact. That clears it for use in food-contact packaging materials like baking paper and oil-resistant papers, which is a meaningfully higher bar than most industrial bioplastic applications need to clear.

Avebe's own positioning is worth noting precisely, because it's more modest and more credible than sweeping "replace all plastic" bioplastic marketing tends to be: potato-starch-based barrier films as a biodegradable, food-safe, cost-effective alternative to conventional fossil-fuel-derived synthetic adhesives and coatings — a direct substitution aimed at one well-defined category of petroleum-based packaging chemistry, not a claim to replace plastic broadly across every application.

The broader starch-bioplastics market is described as moderately consolidated, with major players including NatureWorks LLC, Total Corbion PLA, BASF SE, Biome Technologies plc, and PTT MCC Biochem Co., Ltd., alongside a long tail of smaller regional producers. The environmental case cited across the industry centers on reduced carbon footprint relative to petroleum-based plastics, lower production energy requirements, and — the detail that matters most for packaging specifically — genuine biodegradability, as opposed to the partial or conditional biodegradability some competing "bio-based" plastics can only claim under narrow industrial composting conditions.
