Selection Principle of Opening Carton
When choosing corrugated cartons, we should first take into account the nature, weight, storage and transportation conditions and circulation environment of the products. Secondly, we should design the corrugated cartons according to the design principle of shock-proof packaging and the design method of corrugated cartons. Otherwise, we should follow the relevant specifications. For example, the packaging of export commodities should conform to international standards or the requirements of foreign businessmen, and pass relevant tests. Therefore, corrugated cartons should generally be retained when choosing packaging. Meaning the following two points:
(1) Corrugated models of corrugated cardboard can be divided into four categories: A, B, C and E according to the height of corrugated cardboard. The mechanical properties of different corrugated cardboard are also different.
Type A corrugated cardboard has the highest plane pressure and higher compressive strength, while type B has the opposite effect. Type C has better plane pressure, straight pressure, parallel pressure and buffer force. The thickness of corrugated cardboard is the largest, type C is the second, type B is the second and type E is the smallest, because the cardboard with small thickness is easy to bend, so type B corrugated cardboard is widely used for low compressive strength of boxes.
