Which physical detection and meaning does the carton need to do?

The carton needs to do the following related project tests. Each test is related to the quality assurance of the carton. What are the important detection significances of the carton detection devices? Kunshan Haida instrument here for everyone to analyze in detail:

1. The significance of the side pressure strength test: directly affect the support strength of corrugated boxes, the corrugated boxes are mainly supported by gravity, and the side pressure is the best way to check the strength of the crucible;

The main factors influencing the side-press strength of corrugated board are: the production process of corrugated board, the structure of corrugated board, the corrugated corrugated board, and the influence of corrugated adhesive.

The definition of side pressure strength: in the corrugated direction, a certain height (25mm) of corrugated board, the unit length (100mm) can withstand the vertical and uniform increase (12.5mm/min) force, called the corrugated board side pressure strength .

2, the significance of burst strength test: the impact of corrugated box side support strength - corrugated box protection products, resistance to break is the assessment of the unit area of ​​the board can withstand the uniform and increase the maximum pressure value. The test is to examine the ability of the carton to withstand static local extrusion in the actual transport environment;

Definition of burst strength: The maximum pressure that a corrugated board can withstand evenly per unit area is the burst strength of corrugated board.

3, the significance of the puncture strength test: check the resistance of the board to withstand external sudden shock energy;

The definition of the puncture strength: The work done by the corrugated board with a certain shape of the corner cone, the energy shown is called the puncture strength of the corrugated board.

4, the significance of the adhesive strength test: the lack of adhesive strength is likely to cause delamination, greatly reducing the compressive strength of the carton;

The definition of bond strength: the degree of peak adhesion of corrugated board face, back, core paper and corrugated corrugated paper, the maximum peel force that can be subjected to the separation test within a certain unit length.

5, the significance of the thickness test: If the cardboard in the processing process, the loss of corrugated height is too large, such as after die-cutting, that is, indentation, grooving or printing, will be greatly reduced. The compressive strength of the carton, so keeping the thickness of the corrugated board should be a key part of the production process.

The definition of thickness test: The height that corrugated board shows under certain pressure is called thickness.

6. The significance of the compressive strength of corrugated boxes: to assess the maximum pressure value of the carton, the product protection strength of the carton packaging design, and to check whether the carton can bear the stacking weight;

The definition of the corrugated box compressive strength: the force generated by the uniform displacement increases the compression of the carton. The maximum force that the carton can withstand is called the compressive strength.

Compression strength pass judgment: When the measured pressure resistance values ​​of the three sample boxes are all greater than the standard pressure resistance value, the test is qualified; if one of the sample boxes is unqualified, the test is unqualified.

7. Other tests: flat compressive strength test (ISO3035) (force per unit area of ​​64.5cm2 32.2cm2)

Bending Stiffness Test (IS05628) (four point stiffness, calculating deformation force)

Surface water repellency (JIS-P8137) (Refer to the water repellency standard board)

Vertical strength test (JIS-Z0403-2) (special fixture, special cutter)

Moisture resistance test (GJB1109A) (250mm*250mm 4 pieces, 50 degrees 90%RH 48h, before and after the water difference is not more than 5%.
