Fully Automatic Egg Carton Production Line

· Product Overview

The fully automatic rotary-drum egg-carton production line comprises a pulping system, a forming system, a drying system, a stacking system, a vacuum system, a high-pressure water system, and a compressed-air system. It is specifically designed for manufacturing egg-carton products in sizes such as 10-, 12-, 15-, and 18-egg configurations. The process uses waste paper—including used newspapers, waste cardboard and cartons, office paper, and trimmings—as raw materials. These materials are mechanically pulped, filtered, and mixed with water to achieve a specified pulp consistency. The resulting pulp is then fed into the forming system, where it is vacuum-formed into wet blanks on specially designed metal molds. The blanks subsequently pass through a drying line for dehydration and are subjected to in-line hot pressing before being stacked to complete the final product.
