Carton compressive strength is summarized according to standards and calculation methods
In the carton production industry, it is well-known that carton dynamic performance tests are applicable to the packaging of certain specific commodities, such as ceramics, glassware, electrical appliances, instruments, etc. If we want to check the cushioning performance of cartons on commodities, imitate transport, handling, vibration, and drop. And other tests. At the same time, it is necessary to test the strength of the carton, such as burst strength test, puncture strength test, ring pressure strength test, and compressive strength test of the carton; among them, the compressive strength of the carton is the most important quality of many commodity packaging requirements. Index, the corrugated box is placed between the two pressure plates during the test, and the pressure at the time of pressurization until the carton collapses is the compressive strength of the carton.
   The above is a partial summary of the quality inspection of the carton manufacturing industry. The carton compressive strength test must understand the calculation of its strength value, and the calculation basis and influencing factors of the carton compressive strength. Haida Instrument Co., Ltd. makes the following analysis for you.
   We can calculate the compressive strength of the carton based on the raw materials, and after the compressive strength of the carton is predetermined, we should select the appropriate carton board and corrugated medium to produce the corrugated carton to avoid waste caused by blind production; calculate the carton according to the ring pressure strength of the original paper. There are many formulas for compressive strength, but the more concise and practical is the kellicutt formula, which is suitable for estimating the compressive strength of 0201 carton.
At the same time, the method of determining the compressive strength of carton is also very important. Due to various factors in the production process, the compressive strength of the cartons produced with raw materials is not always exactly the same as the estimated results. Therefore, the ultimate method for accurately determining the compressive strength of corrugated cartons is to use carton compression after constant temperature and wet treatment of the cartons. Test machine test; For small and medium-sized plants without test equipment, a wooden board can be placed on the top of the carton, and the same amount of heavy objects can be stacked on the wooden board to roughly determine whether the carton compressive strength meets the requirements.
