A corrugated packaging machine is specialized equipment designed for the production of corrugated cardboard, primarily comprising components such as a single-facer, a double-facer, and a cutting system. Its core function involves a mechanical process wherein flat paper is pressed into a wave-like corrugated structure, which is then bonded to a liner sheet to form corrugated cardboard possessing cushioning properties. The operational workflow can be divided into three distinct steps:
Raw Paper Unwinding: The paper web is smoothly conveyed from the roll to the preheating rollers via a tension control system.
Corrugating and Forming: The paper passes through high-temperature (typically 160–180°C) corrugating rollers, where it is pressed to form a uniform corrugated wave pattern.
Bonding and Setting: The inner liner and outer liner are bonded together using starch-based adhesive, and-following a drying process-form either three-layer or five-layer corrugated cardboard.
