How Are Corrugated Boxes Made?

Corrugated packaging is one of the most sustainable packaging solutions in the world. It’s made from trees and recycled materials, ensuring an eco-friendly process.

♻️ Step-by-Step Corrugated Manufacturing Process

  1. Recycling: Old corrugated containers (OCC) are collected, sorted, and baled.
  2. Breaking Down: The bales are sent to paper mills, where they are turned into a fiber pulp.
  3. Screening & Cleaning: The pulp is refined to remove contaminants.
  4. Drying & Forming Sheets: The clean fiber is turned into rolls of paperboard.
  5. Corrugating & Cutting: These sheets are processed into corrugated boards, which are then cut and shaped into boxes.

📌 Fun Fact: The corrugated packaging industry boasts a 96% recovery rate!
