5 Strong catamaran color felt manufacturer by single pit color felt manufacturer evolved, its middle layer of core paper core paper stacked by the two thick bonded. After decades of exploration and development of domestic manufacturers have today can produce a variety of different combinations of corrugated color felt manufacturer. This color felt manufacturer has a different character and strength to meet changing market needs.

Paper core material

Corrugated color felt manufacturer pits larger diameter, the stronger its rigidity. color felt manufacturer toughness stems from core paper layers thick hard without filler. This will reduce the weight and cost of color felt manufacturer. By semi-chemical pulp core paper (this can provide the best paper pulp strength) and materials made of recycled paper. The latter due to low cost, so for Hong Kong manufacturers are willing to adopt, although the paper strength than the former, but may add starch mills to be improved.

Within the corrugated grooves occupy a certain space, the role is also very important, it can withstand level by pressure side pressure, and other various irregular pressure.
