What is PLA Coated Paper?

PLA coated paper, also known as polylactic acid coated paper, is a type of food-grade paper that is coated with a PLA film layer. This coating provides the paper with water resistance, making it a viable alternative to plastic food packaging. PLA coating is made from cornstarch and sugarcane, which are renewable resources. It is 100% biodegradable and compostable within 6-12 months under specific composting conditions.

The PLA coating used on the paper complies with Bio-standards and FDA regulations, ensuring that it is safe for food contact. This makes PLA coated paper an ideal choice for various food packaging applications.

How is PLA Coated Paper Made?

The process of making PLA coated paper involves coating a base paper with a thin layer of PLA. The base paper can be different types, such as kraft paper, white paper, or bamboo paper, depending on the specific requirements of the application.

To create the coating, the PLA film is melted and then applied to the base paper using a laminating process. The paper is then cooled, resulting in a thin layer of PLA on the surface. This coating provides the paper with water resistance, ensuring that it remains durable and functional in various food packaging applications.
