Corrugated cardboard is a composite material composed of corrugated paper and tissue paper, with rich performance indicators to evaluate its quality and suitability. Common corrugated cardboard performance indicators include the following aspects:
1. Corrugated form of corrugated board: Corrugated board usually has three corrugated forms, namely A tile, B tile and C tile. Each corrugated form has different strength and performance characteristics.
2. Load-bearing capacity (compressive strength): The load-bearing capacity of corrugated cardboard is an important indicator for evaluating its compressive performance. It is usually measured by the maximum resistance of a certain number of stacked corrugated boards when subjected to a specified pressure in the vertical direction.
3. Thickness of corrugated cardboard: The thickness of corrugated cardboard affects its impact resistance and compression resistance. Usually measured in millimeters (mm).
4. Corrugated board density: The corrugated board density refers to the weight of the corrugated core paper per unit area, usually expressed in grams per square meter (gsm). Higher corrugation density usually means higher strength and hardness.
5. Moisture resistance: The moisture resistance of corrugated cardboard refers to its performance in a humid environment. The moisture resistance of corrugated cardboard is evaluated by testing its moisture resistance under certain humidity conditions.
6. Adjustability and foldability: Corrugated cardboard can usually be adjusted and folded into the desired shape as needed. This property makes it an ideal material in packaging and transportation.
7. Tear strength: Corrugated cardboard should have a certain tensile and tear resistance to prevent breakage and damage during packaging and transportation.
The metrics and requirements for evaluating the performance of corrugated board will vary depending on the specific application and usage needs. According to different packaging needs, the appropriate corrugated form, thickness of corrugated cardboard, and corrugated density can be selected to meet the needs of different packaging and transportation environments.
