Heavy-Duty Edge Protection

Cardboard corner guards are made of multi-layer composite hard cardboard, with L-shaped or U-shaped cross-sections and a thickness of 5-8mm, offering high stiffness and toughness, which can protect both carton corners and edges simultaneously. With a compressive strength of ≥40kPa, they can withstand heavy stacking pressure.

Cross-Section Customization

Cardboard corner guards support customization of different cross-sectional shapes such as L-shaped and U-shaped, and can be customized in size according to carton height and width. Reinforcing rib design is provided to enhance load-bearing capacity, adapting to the protection needs of heavy cartons and large cartons.

Heavy & Large Carton Adaptability

Suitable for edge and corner protection of heavy industrial cartons, building material packaging cartons, large home appliance cartons, etc., cardboard corner guards meet the needs of factory outbound, cross-border sea shipping, engineering procurement packaging, and other scenarios, with significant heavy-duty protection effects.

Summary: Composite materials achieve heavy-duty protection, multi-cross-sectional shapes adapt to different needs, and reinforcing design enhances load-bearing capacity, making cardboard corner guards a strong protection accessory for heavy and large cartons.
