PLA Coated Paper for Food Packaging
PLA coated paper combines paper or paperboard with a plant-based PLA barrier layer to provide moisture and grease resistance for selected food packaging applications. It is commonly considered for projects looking for an alternative to conventional PE coating, especially where compostability or renewable material content is part of the packaging requirement.
- Barrier Layer: Plant-based PLA (Polylactic Acid)
- Functionality: Moisture & Grease Resistance
- Compliance: Industrial Compostable & Renewable Content
What Is PLA Coated Paper?
PLA coated paper is paper or paperboard coated with a thin layer of polylactic acid (PLA), a bio-based polymer commonly made from renewable plant-derived feedstocks such as corn or sugarcane.
In food packaging, the PLA layer provides a barrier against moisture and grease while helping the paper maintain the structure and sealing performance required for selected cups, bowls, and food containers.
PLA coated paper is commonly considered when a packaging project requires renewable material content or a compostable coating option, provided the complete packaging structure and local disposal conditions support those goals.
Why Use PLA Coating for Food Packaging?
PLA coating provides the functional barrier needed for selected paper food packaging while offering a bio-based alternative to conventional fossil-based PE coatings. Depending on the packaging structure and PLA grade, it can provide:
Helps protect paper from liquids and condensation.
Suitable for selected food-contact applications.
Supports forming and sealing for compatible packaging structures.
PLA is produced from renewable plant-derived feedstocks.
Suitable PLA systems can support certified industrially compostable packaging when the complete package meets the applicable requirements.
Typical Applications of PLA Coated Paper
Paper Cups
Suitable for selected beverage applications where a plant-based barrier coating is preferred.
Paper Ice Cream Cups
Well suited to frozen desserts and other cold food applications requiring moisture and condensation resistance.
Paper Bowls
Suitable for salads, desserts, noodles, and other food applications where moisture or grease resistance is required.
Paper Food Boxes & Containers
Used for bakery, dessert, chilled food, takeaway, and other packaging applications where a PLA barrier can support both functional and sustainability requirements.
PLA Coated Paper vs PE Coated Paper
Both PLA and PE coatings provide moisture and grease resistance for paper food packaging, but they differ in raw material source and end-of-life options.
| Feature | PLA Coating | PE Coating |
|---|---|---|
| Material Source | Bio-based polymer commonly made from renewable plant-derived feedstocks | Conventional fossil-based polyethylene |
| Moisture & Grease Resistance | Suitable for selected food packaging applications | Reliable and widely used across many applications |
| Heat Sealability | Available with suitable PLA grades and packaging structures | Commonly used for heat-sealed paper packaging |
| Compostability | Can support industrial compostability when the complete package meets applicable requirements | Not compostable |
| Typical Applications | Cups, ice cream cups, bowls, and selected food containers | Widely used across cups, bowls, and food containers |
What to Confirm Before Ordering PLA Coated Paper Packaging
PLA coating performance depends on the packaging structure, food application, and the specific PLA grade used. Before confirming the specification, consider the following:
Food & Temperature
Confirm whether the packaging will be used for cold, frozen, room-temperature, or hot food applications.
Required Barrier Performance
Identify the level of moisture, grease, and oil resistance required for the product.
Heat-Sealing Requirements
If the packaging needs heat sealing during forming or closing, the PLA coating should be matched to the production process.
Paper & Coating Structure
Base paper, coating weight, and packaging construction can affect barrier performance and finished product stability.
Compostability Requirements
If industrial compostability is part of the project requirement, the complete packaging structure and applicable certification requirements should be confirmed.

PLA Coated Paper & Compostability
PLA is a bio-based material made from renewable plant-derived feedstocks and is widely used in packaging projects that aim to reduce reliance on conventional fossil-based plastics.
For suitable packaging structures, PLA coated paper can support industrial compostability when the complete package meets the applicable compostability requirements and is processed in appropriate industrial composting facilities.
