Double corrugated carton A*A A is what mean

Now in the packaging, corrugated packaging is widely applied, corrugated cartonweight, ingenious structure, soft texture, convenient package, easy operation, easy to use. But also can when the stacking height, high breaking strength, puncture strength, and has a certain buffer performance. Therefore, selection of corrugated box for the outer packing is a good choice. Corrugrted because of no pollution,renewable, has good buffer performance advantages, widely used in transport packaging, in accordance with the standard GBT6544 - 1999, UV - shapedcorrugated board is divided into A, C, B and E four. A flute carton subjected to plane stress performance than B and C type of difference, but the vertical pressure bearing capability is better; the B flute is lower and dense, so the vertical pressureperformance is poor, but the higher plane pressure performance; C type ofperformance, between A and B type; E type. Board has the characteristics of light weight, good buffering performance, plane compressive strength is good, for directprinting. Corrugated corrugated high (mm) Leng number (/300mm) corrugatingcoefficient * A 4.5~5 34 ± 21.58 C 3.5~4 38 ± 21.50 B 2.5~3 50 ± 21.38 E 1.1~2 96 ± 41.30, therefore, A, C the high treng different, price is also different.
