1. Compressive strength
One inherent characteristic of paper straws is their large moment of inertia. When cardboard is subjected to a large moment of inertia, maintaining its original thickness is a prerequisite. Therefore, the ability of cardboard to withstand flat compressive loads without breaking is an important strength indicator of paper straws.
2. Paper straw compression test
Compression resistance refers to the pressure that a paper straw can withstand when placed in a three-dimensional position. The detection method for pressure testing is to seal three sample tubes in three dimensions, seal them up and down with sealing tape, place them in the middle of the lower pressure plate of the compression testing machine, and start the machine to make the upper pressure plate close to the empty tube body. Then start pressurizing at the standard speed until the pipe yields.
