Cartons are made up of various layers of paper, and the reasonable collocation of paper is the basic condition to ensure the compressive strength of cartons. Through the test of physical properties of paper at all levels, we can preliminarily calculate the compressive strength of the carton, and then through the calculated compressive strength, we can control the compressive strength of each process in the production process.
The production process of cartons will also affect the compressive strength. The test results show that under the same conditions, the compressive strength of the carton decreases by 90n-130n and the deformation increases by about 2mm when the transverse pressing line of the carton widens by 1mm. Too wide pressing line will result in slow increase of force value, small effective value and large deformation of carton during compression test. In order to ensure the compressive strength, we should try our best to improve the production process and reduce the impact of each process on the compressive strength of cartons.
The influence of moisture on the compressive strength of carton can not be ignored. The production environment, storage environment, use environment, weather, climate and other factors of the carton will affect the moisture content of the carton. In order to ensure the compressive strength of the carton, the influence of external environment on the moisture content of the carton should be avoided as far as possible.
What will happen in the production process of cartons? What factors will affect the production of cartons? What are the above factors.
