The thickness selection for paper corner guards: An analysis from 3mm to 8mm applications

The thickness of the paper corner guards directly affects their protective performance. The common thickness range is from 3mm to 8mm.

Different thicknesses correspond to different load-bearing requirements and application scenarios. For home decoration, corner guards are recommended to be of a thickness of ≥ 5mm. For example, high-strength corrugated paper with a strength of 400g/m² or above can have a load-bearing capacity of over 50kg.

Paper corner protectors with a thickness of 3-4mm are suitable for protecting the edges and corners of lightweight goods.

These protectors are commonly used in the packaging of small e-commerce parcels and lightweight cartons, meeting basic impact prevention requirements at a relatively low cost. For the packaging of daily necessities and small electronic products, this thickness is a cost-effective choice.

The 5-6mm thick paper corner protectors are the mainstream choice for industrial packaging.

Whether it's for household appliances, building materials, or chemical products, this thickness can provide reliable edge protection and stacking reinforcement. For goods that need long-distance transportation or multiple handling, the 5-6mm corner protectors can effectively resist various impacts.

Paper corner guards with a thickness of 7-8mm or more are suitable for heavy equipment and special scenarios.

For goods such as heavy machinery, steel products, and large furniture, the pressure resistance of the corner guards is extremely demanding. Therefore, it is necessary to choose a thicker specification to ensure that the corner guards remain intact under extreme conditions.
