The main process of producing double insert corrugated box

Producing Corrugated Board
Large rolls of paper are processed in a single-facer to create the corrugated structure.
The process involves heating the paper to about 338°F (170°C) with steam. Adhesive is then applied to the top of the corrugations to bond the corrugated paper to the backing paper. Rollers are then used to flatten the combined layers, creating a single-faced roll.

After the single-facer leaves the single-facer, it goes to a double glue unit and double backing.

After the corrugated board passes through the double backing machine, it goes through a dryer, is scored, and then cut to size.

Corrugated boards of different sizes are collected and prepared for the box printing and manufacturing process.
Depending on the box specifications, various logos, designs, and colors are printed on the board.

Final Forming of Corrugated Boxes
The scored, printed, and cut corrugated board passes through a trimming machine to create flaps and handles.
After trimming, the box goes to a folding machine, which folds the box along the score lines and applies adhesive to the parts that need to be sealed to complete the box assembly.

Quality Control
Finished boxes go through inspection processes to ensure they meet quality standards, including strength and appearance.

Demonstrate the strictness of quality inspection

Testing and inspection of corrugated boxes is essential to ensure that they meet the necessary standards of strength, durability, and performance during handling, transportation, and storage. The following are the key aspects of testing and inspection of corrugated boxes:

The burst strength test

Is a standard industry measurement method that tests the durability of the corrugated board surface by determining the force required to puncture the board.

The edge compression test

Is one of the essential tests for corrugated board.
It determines the weight that the box can withstand when pressure is applied from the side. This is done by applying pressure to the edge of the corrugated board until it crushes.

Flat Compression Test (FCT)

Evaluates the strength of paperboard and corrugated paper when subjected to pressure. It measures the force required to crush a flat corrugated sample.

Humidity and Temperature Test

Tests the behavior of the box under various environmental conditions by exposing it to different humidity and temperatures. This is very important for products that are sensitive to humidity or specific temperatures.
