1、 Introduction: The Industry Need and Technical Significance of Carton Compression Testing

In logistics transportation, warehousing stacking, product protection and other links, cardboard boxes are commonly used as packaging carriers, and their compressive strength directly affects the safety of product transportation, storage space utilization, and enterprise logistics cost control. According to industry data statistics, approximately30%The transportation loss is caused by the deformation and collapse of cardboard boxes due to insufficient compression resistance. Therefore, accurate detection of cardboard box compression resistance has become a mandatory quality control link in industries such as food, electronics, home appliances, and express delivery. As a professional testing equipment, Taichang Instrument's cardboard box compression testing machine has become a core tool for enterprises to achieve packaging quality standardization with its high-precision testing capabilities and intelligent operation design.

2、 Core application scenarios of Taichang Instrument cardboard compression testing machine

Paper box production enterprises need to verify whether their products meet the requirements through compression testingGB/T 4857.4TheISO 12048Wait for national standards to ensure that the compressive strength, burst resistance, and other indicators of each batch of cardboard boxes meet the standards. Taichang Instrument Equipment supports continuous testing of batch samples, automatically recording test data and generating qualified ones/Unqualified judgment report, suitable for quality control throughout the entire production line process.

2. Optimization of packaging scheme

Terminal enterprises (such as food and beverage, electronic product manufacturers) can compare the compressive performance of cardboard boxes of different materials, structures (corrugated types, layers), and sizes through this device when selecting cardboard boxes. Combined with product weight, transportation distance, stacking height, and other parameters, the packaging plan can be optimized to reduce costs. For example, testing can accurately determine whether it meets the requirements 3 The minimum cardboard box weight required for layer stacking achieves lightweight packaging design.

3. Storage and transportation simulation testing

For long-distance transportation and multi-layer stacking storage scenarios, the equipment can simulate the compressive attenuation law of cardboard boxes in a static stacking state, test the compressive stability of cardboard boxes under different environmental temperatures and humidity (combined with constant temperature and humidity boxes) and different stacking times, and avoid the risk of storage collapse and transportation damage in advance.
