Carton factory cardboard materials are divided into what material and strengthen not reinforced, and what three, five layers, how to classify ah?
Cartons according to different materials, corrugated boxes, single cardboard boxes, etc., with a variety of specifications and models. According to the demand of commodity packaging, corrugated paperboard can be processed into single-sided corrugated paperboard, three ply corrugated paperboard, five ply, seven ply and eleven ply corrugated paperboard. Commonly used are three, five, and seven uses less.
There is a strengthening. The core surface strengthening three layers of paper, which is to strengthen the carton has direct relationship to the strength of resistance. The three layers of paper used in the paper and the higher level of weight, make the carton bursting strength is higher. All matching paper cartons can according to the paper original physical index to calculate the theoretical physical indexes of carton.
Corrugated carton paper is selected according to the physical indexes of paper products required to install the carton, such as compressive strength requirements and breaking resistance requirements. Strengthen the distinction and strengthen again in the three layer board is not used high-strength corrugated corrugated paper, high-strength corrugated weight, weight is not the same, the strength of different if not strengthen, three layers of corrugated paper generally used are puite paper! Five plates do not strengthen the case is a corrugated paper layer is a layer of phuvah, is high, if is used to strengthen the two layers of corrugated paper are high strength corrugated paper do. The above said is these are about carton resistance, the use of the high paper weight is high, anti pressure carton is stronger.
