Waterproof Single Or Double Side PLA Coated Paper Rolls For Making Food Containers

Why Use PLA Coated in Making Paper Rolls?

The primary reason for using PLA (Polylactic Acid) coating on paper rolls is to create a high-performance, biobased and compostable alternative to traditional polyethylene (PE) plastic coating. It combines functionality with sustainability.

Key Reasons and Advantages:

1. Environmental Sustainability:

   • Biobased & Renewable: PLA is derived from plant resources like corn starch, sugarcane, or cassava. This reduces dependence on finite fossil fuels (the source of PE).

   • Industrially Compostable: Under the right conditions in an industrial composting facility, PLA-coated paper products can break down into water, carbon dioxide, and organic matter (compost) within a few months. This offers a genuine "end-of-life" solution, unlike conventional plastics that persist for centuries.

2. Reduced Carbon Footprint:

   • The production of PLA generally generates fewer greenhouse gas emissions compared to the production of petroleum-based plastics like PE. This contributes to combating climate change.

3. Excellent Functional Performance:

   • Good Barrier Properties: PLA provides very good resistance to oil, grease, and fats, making it ideal for food packaging like boxes for fries, pizza, and pastries. It also offers a moderate barrier against moisture and water vapor.

   • Heat Sealability: Similar to PE, PLA can be heat-sealed to form strong, tight seams for bags, pouches, and the bottoms of paper cups. This allows it to work on existing packaging machinery with some adjustments.

   • Clarity and Gloss: PLA coating can provide a very clear and glossy finish, which enhances the visual appeal of printed designs on the paper.

4. Brand Image and Consumer Demand:

   • Using PLA-coated materials allows brands to align with eco-friendly values and market their products as "compostable" or "biobased." This meets the growing consumer demand for sustainable packaging.

In summary, PLA coating is used to provide the essential barrier and sealing functions of plastic, but with a dramatically improved environmental profile. It is the material of choice for brands and converters aiming to reduce their reliance on conventional plastics and offer compostable products.
