PLA coated paper is a sustainable packaging material in which the surface of the paper is laminated with a thin layer of PLA (polylactic acid), a bio-based and compostable plastic made from renewable resources such as corn or sugarcane.
The PLA coating provides water, oil, and moisture resistance while keeping the packaging environmentally friendly.
PLA coated paper is increasingly used as an eco-friendly alternative to traditional PE-coated paper in food packaging, takeaway containers, paper cups, and paper bowls.
Key Features of PLA Coated Paper (For Packaging Use)
1. Eco-Friendly and Compostable
PLA is derived from renewable plant starches and can break down in industrial composting facilities. It contains no petroleum-based plastic, making it ideal for sustainable packaging.
2. Excellent Water and Oil Resistance
The PLA coating forms a barrier against liquids, grease, and moisture, making it suitable for:
Takeaway food boxes
Trays for fresh foods
Sandwich and burger wraps
Paper cups and paper bowls
3. Food-Safe and Odor-Free
PLA contains no BPA, no heavy metals, and no toxins. It is safe for direct food contact and widely used in the food-service industry.
4. Natural Look with Good Printability
The paper base retains its natural texture while supporting offset, flexo, and screen printing—ideal for brand customization and premium packaging design.
5. A Sustainable Alternative to PE Coating
Compared to traditional polyethylene (PE) coatings, PLA is more environmentally responsible and easier to manage after use, making it a preferred material for “green packaging” initiatives.
Common Applications of PLA Coated Paper
Takeaway containers and food trays
Hot and cold beverage cups
Paper bowls and plates
Sandwich bags and burger wraps
Baking sheets and food liners
Grease-resistant inner layers for paper bags
Fresh food and produce packaging
Suitable for any application requiring oil resistance, water resistance, or leak prevention.
FAQ
1. Is PLA coated paper truly biodegradable?
Yes. PLA is a bio-based polymer that decomposes into CO₂ and water under industrial composting conditions.
2. Can it replace PE coated paper?
Yes. PLA is widely used as an eco-friendly substitute in food service and takeaway packaging.
3. How heat-resistant is PLA coated paper?
Standard PLA withstands about 50–60°C.
For hot beverages, modified PLA (such as CPLA) is commonly used.
4. Can PLA coated paper carry sustainability logos like FSC?
Yes, as long as the paper base is certified and production meets chain-of-custody requirements.
