Henan Huagang Printing Co., Ltd.

Four major inspection checkpoints

Incoming inspection of raw paper

Drilling inspection

Re-inspection of heat transfer gloss

Finished product slitting and full inspection

Test the uniformity of weight, tensile strength and tensile index, and strictly control the standards for food-grade substrates.

During laser drilling, the density and diameter of the micropores are scanned at high frequency to correct air permeability deviations in real time.

Photoelectric comparative sampling tests were conducted on the adhesion of the hot stamping layer, the abrasion resistance of the ink, and the registration accuracy.

The flatness of the end face and the absence of burrs on the cut of the roll end face are inspected, and a physical report is attached for each batch.

Breathability and resistance control

Data-driven control of microporous air permeability

The laboratory is equipped with an automated perforation air permeability tester and tensile testing machine to perform high-pressure gas permeability and physical tensile strength tests on each set of tipping paper samples. The test data is directly entered into the quality tracking system to ensure the consistency of suction resistance and the compliance rate of batch production.

To meet the requirements of high air permeability and laser perforation, Borun provides a complete set of data testing reports to satisfy the stringent requirements of cigarette factories for combustion rate and draw resistance stability.
