Brief Introduction

In the modern packaging industry, ensuring the transportation safety and integrity of products is crucial, and as corrugated cardboard is the main packaging material, accurate evaluation of its physical properties is the key to ensuring packaging quality. The YSD-03 cardboard compression strength tester from Sanquan Zhongshi is a comprehensive testing equipment that integrates high precision and multiple functions. It is designed specifically for testing various physical properties of corrugated cardboard and paper, including but not limited to ring compression strength, edge compression strength, adhesive peel strength, and flat compression strength. It is widely used in papermaking enterprises, packaging manufacturers, quality inspection centers, and other fields, providing strong support for strict control of product quality.

1、 Edge compression strength test: Guardian of stacking performance

Edge compression strength is an important indicator for measuring the compressive strength of corrugated cardboard in the vertical edge direction, which is directly related to the stability and load-bearing capacity of cardboard stacking. The cardboard compression strength tester precisely controls the vertical pressure applied to the edge of the specimen until it fails, and records the maximum pressure value at the moment of failure, which is the edge compression strength. High edge compression strength means that cardboard boxes can more effectively resist deformation and collapse when stacked, ensuring the safety of goods during storage and logistics processes.

2、 Adhesive strength test: the cornerstone of structural stability

The adhesive strength test focuses on the firmness of the bonding between the layers of corrugated cardboard, which is the key to ensuring the overall structural integrity of the cardboard box. The YSD-03 cardboard compression strength tester for Sanquan Zhongshi accurately measures the force required to separate the bonded areas of the cardboard by applying directional tension to these areas. Excellent adhesive strength can prevent delamination of cardboard boxes under stress, maintaining the integrity and protective effectiveness of the packaging. For preventing product damage due to packaging damage, adhesive strength testing is conducted.

3、 Flat compressive strength test: guarantee of flat compressive strength

The flat compression strength test evaluates the compressive strength of corrugated cardboard under uniform vertical pressure, which is particularly suitable for packaging scenarios that require bearing flat pressure, such as pallet packaging. The YSD-03 cardboard compression strength tester places the sample on a dedicated platform, applies uniform pressure until it breaks, and records the pressure value and deformation situation. High compressive strength means that the packaging can effectively resist external pressure during transportation and storage, protecting the contents from compression damage.
