Information summary
The use of standardization reduces a lot of unnecessary troubles for market docking. When custom-designed cartons can be directly designed according to the standard, then cartons meeting the requirements of use can be produced.
Due to the extensive development of international trade, the competition of products in the international market is becoming more and more fierce. Products are required to have high quality, good performance, and wide versatility and interchangeability; this requires standards in various countries They are unified and produced in accordance with internationally unified standards.
The strength requirements of corrugated boxes are as follows: edge pressure, burst resistance, and puncture are the same as cardboard. The edge compressive strength of the carton will be lower than the edge compressive strength of the cardboard. Carton Compressive Strength Compressive Strength u003d Edge Compressive Strength (N/cm)*Kerry Carter's Constant F
The F value depends on the perimeter length of the carton, * (length + width) cm. and corrugated type. After the two items are determined, the F value can be checked in the table. The actual compressive strength test value is related to the ratio of carton length, width, and height. The higher the height of the same corrugated carton with the same peripheral length and the same material, the smaller the compression resistance; the greater the length * width of the bottom area, the greater the compression resistance.
Compressive strength of machine package boxu003dCompressive strength of corresponding ordinary box type*.*.*Shake cover width/carton width.
The bonding strength of carton and cardboard. The force required to separate the cardboard and corrugated paper per unit length. The unit is N/m. The industry standard uniformly stipulates that it is greater than N/m.
Stacking strength and compressive strength. The required compressive strength of the carton u003d [carton gross weight * (stacking layers)] * safety factor K. The front part is the static stacking strength of the cartons. The K value depends on the number of printing plates, the degree of opening, the nature of the inner packaging, the degree of preciousness, storage and transportation time, conditions, etc. The K value is generally -.
