Different production environments and processes for corrugated packaging boxes

Corrugated packaging boxes production environment:

Mainly when the temperature does not exceed 33 ℃ and the humidity in the air does not exceed 45%, otherwise the cardboard of the cardboard box is prone to moisture and the moisture itself is not easily evaporated, which reduces the pressure that the cardboard box can withstand. In addition, it is best to rotate the mounted small box blank for 4 hours before molding. Sometimes, due to customers' urgent need for products, a fan can be used to forcefully blow air to promote the quick bonding of the cardboard and evaporate excess moisture. Improve the pressure resistance of corrugated cardboard packaging and reduce various adverse factors.

Production process of corrugated corrugated paper boxes:

By squeezing and forming the upper and lower corrugated rollers, the upper paste roller applies paste, and the surface paper and corrugated paper are bonded together to form a two-layer corrugated cardboard at the tangent between the pressure roller and the upper corrugated roller. Then, the belt is transferred to the double-sided machine and combined with other single corrugated cardboard and surface paper to form a composite.
