Nuts Packing Box With Perforation Lines And Self Lock Bottom

Material Structure and Application

Corrugated paperboard can be divided into 3 layers, 5 layers and 7 layers according to the combined structure.

The thicker “A Flute” corrugated box has better compressive strength than “B Flute” and “C Flute”.

“B Flute” corrugated box are suitable for packing heavy and hard goods, and are mostly used for packing canned and bottled goods. “C Flute” performance is close to “A Flute”. “E Flute” has the highest compression resistance, but its shock absorption capacity is slightly poor.
