Greaseproof and Water Resistant PE Coated Paper Roll for Disposable Cups and Containers

Features   

PE Coated Paper, also known as Polyethylene Coated Paper or Poly-Coated Paper, is a composite material made by bonding a thin layer of polyethylene (PE) plastic onto a paper or paperboard substrate. This process is primarily done to enhance the paper's functional properties, making it suitable for applications where plain paper would not suffice.

PE Coating:

• Function: As discussed previously, the Polyethylene (PE) layer is extruded onto one or both sides of the kraft paper. This coating is crucial for:

   

  • Waterproof Barrier: Prevents liquids from soaking through the paper.

     

  • Greaseproof Barrier: Blocks oils and fats from seeping out, ideal for food contact.

     

  • Heat Sealability: Allows the paper to be formed and sealed into a cup shape using heat and pressure.

• Coating Thickness (GSM): The amount of PE applied (e.g., 12gsm, 15gsm, 18gsm) can be customized based on the desired level of liquid/grease resistance and cost efficiency.

• Single or Double-Sided Coating:

  • Single PE Coated: Typically the PE is on the inner side, making it suitable for hot cups where the primary need is to hold the liquid.

  • Double PE Coated: PE on both sides provides enhanced resistance, making it suitable for cold cups (to prevent condensation from softening the outer layer) or for packaging that requires a barrier on both surfaces.
