What is PLA Coated Paper and How is It Made?

Definition and Composition

PLA coated paper, also known as polylactic acid coated paper, is a type of biodegradable paper coating that offers water resistance and environmental benefits. It is made by laminating a thin layer of PLA onto various types of base paper, such as kraft, white, or bamboo paper. PLA, or polylactic acid, is a polymer derived from renewable resources like corn starch or sugarcane.

The main advantage of PLA coated paper is its eco-friendliness. It is made from plant-based renewable resources, reducing reliance on non-renewable petroleum-based coatings. PLA is non-toxic and suitable for food contact, meeting bio-standards and FDA regulations for food safety.

Manufacturing Process

The production of PLA coated paper involves several technical steps. First, the base paper is selected based on the specific application requirements. Kraft paper, white paper, and bamboo paper are commonly used as base papers.

Next, the PLA coating is applied to the base paper. The PLA is derived from renewable plant sources and is melted to form a thin film. This film is then laminated onto the base paper using specialized equipment. The lamination process ensures that the PLA coating adheres securely to the base paper, providing water resistance and durability.

Environmental Benefits

PLA coated paper is considered eco-friendly for several reasons. Firstly, it is made from renewable resources, reducing the dependence on fossil fuels and mitigating the environmental impact associated with petroleum-based coatings.

Additionally, PLA coated paper is 100% compostable. Under industrial composting conditions, PLA biodegrades within 6-12 months, converting into carbon dioxide and water. This reduces landfill waste and contributes to a more sustainable waste management system. It is important to note that PLA requires specific composting conditions to biodegrade, and it is not suitable for home composting.

Compared to traditional polyethylene (PE) coatings, PLA has a lower carbon footprint. PLA production requires less energy and emits fewer greenhouse gases, making it a more environmentally friendly option.

In summary, PLA coated paper is a biodegradable and compostable alternative to petroleum-based coatings. It is derived from renewable resources, provides water resistance, and offers environmental benefits through reduced landfill waste and lower carbon emissions.
