Paper Corner Protectors Application Guide: Three Steps to Build a Solid Packaging Defense Line
Paper corner protectors are classic auxiliary materials for enhancing the strength of packaging structures and protecting the edges and corners of goods. The core application logic lies in "strengthening fragile edges and dispersive external pressure". By following these three steps, you can ensure that it achieves the maximum protective effect.
The first step: Precise selection and positioning
Selection: Based on the edge length of the goods and the required protection height, choose the appropriate size (length L, edge width) of L-shaped or U-shaped corner guards. For heavy goods, choose products with high grammage and multi-layer thickening.
Positioning: Place the corner guards tightly against all exposed edges of the outer packaging of the goods (such as cartons or wooden crates), especially the bottom load-bearing edges and the top edges prone to bumps. Ensure that the protective Angle is completely aligned and closely adheres to the edge line.
Step 2: Firm installation and fixation
Bonding and fixing: Use high-strength double-sided tape or hot melt adhesive, apply it along the entire inner wall of the corner guard, and then press it firmly onto the edge of the packaging box to ensure there is no lifting or gap.
Binding reinforcement: For heavy goods or situations requiring additional strength, packing straps or stretch films can be used to horizontally bind the outside of the corner protectors, making the corner protectors and the goods a rigid whole.
Step 3: System integration and inspection
In coordination with stretch film: After the corner protectors are installed, the stretch film is packed. The pressure of the stretch film will make the corner guards fit more closely, forming a composite protective structure of "soft on the outside and hard on the inside".
Final inspection: Confirm that all corner guards are securely installed without any looseness, and fully cover the edges that need protection, with no sharp corners exposed.
Core value: Paper corner protectors effectively prevent indentation, deformation and cracking by converting the point-like impact force acting on the corners into linear stress dispersed along their length. Correct use can significantly reduce the rate of cargo damage during transportation and is a low-cost, high-return investment in protection.
