corrugated boxIt is a tool made of paper products used for packaging various items. Single pit (3 layers)/double pit (5 layers)/three pit (7 layers)/four pit (9 layers) cardboard boxes, cardboard boxes are subdivided into various types of packaging such as paper boxes, color boxes, color boxes, and oversized odd shaped beer boxes. The cardboard box has low cost, is easy to package, suitable for adding fillers, and is clean. It is suitable for product factory packaging, item transportation, material organization, etc. Packaging cardboard boxes are often used for transportation and product protection, and have strict requirements for their own quality.

The testing items for cardboard boxes include: compression resistance, edge pressure, adhesive strength, puncture, simulated transportation seismic resistance, drop, etc. The corresponding instrument for the compression test displayed by the testing instrument is the European standard paper box compression testing machine, as shown in the figure, which generally has auxiliary structures that can be adjusted uniformly on both the upper and lower sides. During testing, place the cardboard box between two sides, press the surface evenly on the instrument, and apply strong force when the cardboard box is crushed. The edge compression strength testing machine tests the vertical compressive strength of cardboard boxes and boards after sampling, generally expressed as pressure/length.
