Carton stacker test analysis

The carton stacker is mainly used for the compression mechanics testing of the carton. The superiority of the whole machine configuration is relatively strong, the detection parameters are in detail, and the specific detailed standards are for everyone to understand.

With the development of industry, corrugated cartons have been widely used as packaging materials. Due to the low threshold of the corrugated paper box industry, the competition is extremely fierce. Carton users have exposed more or less quality problems in the use of cartons, such as the collapse, cracking, etc., of cartons after stacking, causing many negative effects.

Therefore, more and more carton users have realized the dual significance of packaging for product protection and product image promotion. Carton users have become more professional and rational in determining product quality standards, such as: Adding test equipment to measure the key indicators of the carton... Breaking and anti-stress (or stacking), comprehensive research whether excessive packaging (material design excess), to achieve packaging The design of the material contributes to the optimization of the entire product manufacturing cost.

However, in the process of product inspection, when the carton user assesses whether the product is qualified or not, it often produces deviations in understanding and misjudging the product test results. The following is a detailed analysis and discussion on how to correctly understand and evaluate the anti-stress and stacking test of corrugated boxes, and share personal practical experience with carton enterprises and users.

Carton anti-pressure, stacking test compliance with the requirements must be clear two standards: test status standards, physical indicators.

Carton stacker inspection status analysis

The packaging industry usually adopts the following inspection status of two packaging materials:

Carton pressure tester sample temperature and humidity were (23 ± 2) °C, (50 ± 5)% pretreatment 24h.

Standard Source: SN/T02693-93 "Procedures for the Inspection of Corrugated Carton Containers for Export Goods".

The standard atmosphere for testing pulp, paper, and paperboard should be relative humidity (50±2)%, temperature (23±1)°C, general paper pretreatment 4h, tissue paper at least 5-8h, high basis weight or other paper types at least It takes 48 h or more.

Standard source: GB/T10739-1989 "Standard atmospheres for handling and testing of pulp, paper and paperboard specimens"

The purpose of setting the carton test pretreatment is to make the fibrous tissue structure of each sample in a balanced and stable state, so as not to make the test results produce too large differences and affect the determination of the mechanical properties of the carton.
