ProductDescription

coating machines that use bio coatings are revolutionizing the paper industry by providing an eco-friendly, sustainable solution for producing paper products. These machines apply water-based or biodegradable coatings made from renewable materials like plant-based polymers, reducing harmful chemical use and VOC emissions. Bio coatings enhance the durability and functionality of paper, making it resistant to water, oil, and grease, while being safe for food contact. This technology supports regulatory compliance and aligns with sustainability goals, contributing to less environmental impact. As industries prioritize eco-friendly practices, bio coating machines play a crucial role in advancing greener manufacturing and promoting a circular economy.

Process of Coating

1. Paper Roll

Large rolls of base paper are unwound and fed into the PE coating machine. The paper is precisely aligned and controlled through a system of rollers to ensure smooth and even feeding into the machine.

2. Corona Treatment (Pre-Coating)

Before the PE coating, the paper surface undergoes corona treatment to increase its surface energy. High-voltage discharge (typically between 10-30 kV) is used to treat the paper, creating a high-oxygen surface that improves the paper's adhesion properties and allows better bonding with the PE resin.

3. Bio Coating Material Preparation

Bio Coating Solution: The coating material, often derived from renewable sources such as starch, cellulose, natural gums, or plant-based resins, is prepared.This material can be in the form of a paste or solution and may require heating or emulsifying to achieve the correct consistency for coating.

4. Paper Fan

Polyethylene pellets are melted or dissolved in a heated tank or extruder to form a smooth, molten PE solution. Additives like stabilizers or wax may be mixed into the PE to enhance adhesion, surface smoothness, or specific functionality.

5. Coating Application (Extrusion)

The melted PE resin is extruded onto the paper surface through a die nozzle or extruder, ensuring an even and uniform layer.

6. Cooling and Solidification

The coated paper passes through a cooling system—typically using chilled rollers to rapidly cool the molten PE coating. This solidifies the PE layer, ensuring it adheres strongly to the paper surface, creating a waterproof, durable coating.
