The manufacturing of disposable paper cups is a continuous, high-speed process on an automated production line. Here are the key steps:

Raw Materials:

  • Paperboard: Blanks of paperboard, pre-printed with designs.

  • Polyethylene (PE) or Polylactic Acid (PLA) Pellets: For the waterproof coating.

Step-by-Step Manufacturing Process:

  1. Printing & Coating (Offline or Inline):

    • The paperboard is first printed with the desired design using flexographic or offset printing.

    • It is then coated on one or both sides with a thin layer of PE (for standard cups) or PLA (for compostable cups). This coating makes the cup waterproof and prevents leakage. This step can be done beforehand (pre-coated board) or as part of the cup-making line.

  2. Winding & Blanking:

    • The large rolls of coated paperboard are fed into the cup-making machine.

    • A machine cuts the large sheets into rectangular blanks, which are the correct size for a single cup.

  3. Forming the Cup Body:

    • The blank is fed into the cup-making machine and wrapped around a cylindrical mandrel (mold).

    • The longitudinal (vertical) seam is sealed by heating the PE/PLA coating and pressing it together, creating a strong "side seam."

  4. Bottom Forming:

    • A separate disc, punched from the same coated paperboard, is fed into the machine. This will become the cup's bottom.

    • The open bottom of the cup body is heated to soften the coating.

    • The bottom disc is pressed precisely onto the heated rim. The machine curls both the cup wall and the bottom disc inward, and then presses and heats them to form a tight, leak-proof seal. This is called the "bottom curl."

  5. Rim Curling:

    • The top of the cup (the rim) is rolled outward to form a smooth, safe, and rigid curl. This makes the cup more comfortable to drink from and adds structural strength.

  6. Quality Control & Packaging:

    • Cups are automatically inspected for sealing defects.

    • They are stacked, bundled, and packaged into sleeves or bulk boxes for shipping.
