What requirements do different goods have for paper corner protectors

Vary by "item" : The core requirements for paper corner protectors of different goods

The selection of paper corner protectors should closely fit the characteristics of the goods to achieve precise protection and cost optimization. The key requirements for different goods are completely different:

Heavy or high-stack goods (such as large machinery, building materials pallets)

This type of goods is under great pressure. The core requirement is that the paper corner protectors have extremely high longitudinal compressive strength (ECT value). It is necessary to select thickened corner guards with high specific weight, multiple layers and tight pressing to ensure that they are not crushed during long-term stacking or transportation jolts, providing a solid skeletal support for the entire stack shape.

Surface-vulnerable or high-value goods (such as pianos, high-end furniture, coated glass)

The key point of protection lies in preventing surface scratches and bumps at the corners. The corner protectors themselves should have a smooth and clean surface, with precise folded corners and moderate hardness, which can perfectly fit the corners of the goods and avoid damaging the paint or surface layer of the goods due to uneven corner protectors.

Goods of extremely long length or irregular shape (such as profiles, plates, large fabric rolls)

The key requirements are sufficient length and structural consistency. The corner guards should be able to fully cover the entire fragile edge of the goods and provide uniform support. For curved corners, bendable corner protectors or custom-curved corner protectors should be selected to achieve a tight wrap.

Goods for export or in high-humidity environments

In addition to physical properties, attention should also be paid to the moisture-proof performance and quarantine standards of paper corner protectors. Products that have undergone moisture-proof treatment or meet the requirements of export fumigation (such as those with IPPC marks) should be selected to avoid becoming soft due to moisture or problems during customs inspection.

Summary: When choosing paper corner protectors, one should start from four dimensions: the weight, value, shape of the goods, and the transportation environment, and select products with corresponding compressive strength, protection, size, and special performance in a targeted manner.
