What are the functions of plastic corner protectors in loading and transportation?

1. Physical protection and impact resistance

• Corner protection

Plastic corner protectors wrap the corners of items to form a buffer layer, effectively dispersing the impact force during collision and fall during transportation. For example, after installing corner protectors on the corners of fragile items such as furniture and glass, the risk of corner damage can be reduced by more than 80%. Its PP or ABS material is flexible and can absorb vibration energy to prevent external force from being directly transmitted to the main body of the item.

• Anti-scratch and anti-wear

Corner protectors cover sharp edges to prevent goods from scratching other items or packaging surfaces during stacking or handling. It is especially suitable for goods with fragile surfaces such as electronic products and ceramics to reduce scratches caused by friction.

2. Strengthening packaging structure

• Enhancing overall stability

Plastic corner protectors connect multiple faces of cartons or wooden boxes to form a triangular support structure, which significantly improves the compression resistance of packaging. Tests show that the compressive strength of cartons with corner protectors can be increased by 30%-50%, effectively preventing the deformation of the box caused by stacking during transportation.

• Fixation and anti-displacement

Corner protectors are often used in conjunction with strapping tape or wrapping film to fix the position of goods through the slots or holes designed to prevent the goods from sliding or tipping over during transportation. For example, after using corner protectors on pallet cargo, the tilt stability is improved by more than 60%.

3. Efficiency optimization and cost control

• Standardized loading

Corner protectors make the packaging of irregular items (such as furniture and mechanical equipment) more regular, facilitating the maximum utilization of container space. For example, customized corner protectors with a specification of 80mm can be adapted to the corners of a variety of large equipment, reducing the use of filling materials.

• Reusable

Compared with disposable filling materials, plastic corner protectors (especially PP materials) are wear-resistant and not easy to break, and can be recycled 5-10 times, reducing packaging costs in the long term. Some corner protectors are also designed as foldable structures to save storage space.

4. Adaptability to special scenarios

• Moisture-proof and weather-resistant protection

Plastic corner protectors will not soften and fail in a humid environment like paper corner protectors, and are suitable for sea or cold chain transportation. ABS corner protectors can also withstand temperature changes from -20°C to 60°C, ensuring protection in extreme climates.

• Safety and environmental compatibility

Some corner protectors are made of non-toxic materials (such as acrylic or food-grade PP), which meet the environmental protection requirements of export goods. Luminous corner protectors (containing rare earth luminous materials) can mark the location of goods in low-light environments to avoid handling accidents.
