Factors Affecting The Compressive Strength Of Cartons

When the carton is used, it is required to have a certain compressive strength. From the perspective of the production and design of the carton, there are many factors that will affect its compressive strength.

1: Quality of raw materials

The carton is made of various base paper materials, and the quality of the raw materials can determine the compressive strength of the packaging box after processing.

2: Moisture

When the carton is being treated with slurry, if the water content in the carton is too high, the compressive strength will be deteriorated, and if there is too much water, it will be easily deformed when it is used. There will be a soft feeling.

3: Box type

When the carton is designed for the box shape, the overall design type and size arrangement will have a certain impact on the compressive strength. Some packaging boxes are made of double-layer corrugated cardboard, so the compressive strength is Compared with the single-layer carton of the same specification, it will be significantly improved, while some packaging boxes with special shapes and irregular shapes are not as compressive as conventionally designed packaging boxes.

4: Process deviation

In the process of making the carton, due to improper pressing, the depth of the slot is too deep, and the bonding fastness is poor, etc., the compressive strength of the packaging box will also deteriorate, even if the same material is used. Different packing box manufacturers have different strengths.

5: Opening

On the side with a smaller area, during printing, a large area of opening will lead to poor pressure resistance of the carton, and the difference in pressure resistance on both sides will become significantly larger.
