Paper corner protector and anti-collision bag When customizing U-shaped paper corner protectors, it is necessary to comprehensively consider the specifications, material properties, process quality, cost price and other aspects to ensure that the customized U-shaped paper corner protectors can meet the actual packaging needs. The following are specific aspects that need attention:
Specifications
Paper corner protector and anti-collision bag Accurate measurement:Paper corner protector and anti-collision bag According to the size and shape of the product to be protected, the length, width and height of the required U-shaped paper corner protectors should be accurately measured. For example, when packaging large glass products, longer and wider U-shaped paper corner protectors may be required to provide comprehensive protection; while when packaging small and fragile items, smaller U-shaped paper corner protectors can be selected.
Paper corner protector and anti-collision bag Tolerance range: Clearly define the tolerance range of the size to ensure that the U-shaped paper corner protectors can fit closely with the product or packaging. Generally speaking, the tolerance of length and width can be controlled within ±1mm, and the tolerance of thickness can be controlled within ±0.5mm to ensure the accuracy and stability of installation.
Material selection
Paper corner protector, right angle, male corner Paper type: Common ones include kraft paper, tube paper, etc. Kraft paper has high strength, good toughness, and relatively good moisture resistance; tube paper has a lower cost, but its strength is slightly inferior to kraft paper. If the transportation environment is relatively harsh and high requirements are required for moisture resistance and strength, U-shaped paper corner protectors made of kraft paper should be selected.
Paper corner protector, right angle, male corner Glue quality: The quality of glue directly affects the bonding strength and durability of the paper corner protectors. High-quality glue can ensure that the paper is firmly bonded to each other and is not easy to crack or fall off during transportation. Suppliers can be asked to provide relevant quality inspection reports for glue to ensure that it meets environmental protection and performance standards.

Compressive strength: Determine the compressive strength of the U-shaped paper corner protectors according to the pressure that the product may withstand during transportation and storage. For example, for cargo packaging that needs to be stacked in multiple layers, the compressive strength of the U-shaped paper corner protectors must be high enough to prevent the bottom corner protectors from being crushed. Generally, a certain KPa value is required, and the specific value can be determined through compression tests according to actual conditions.
Buffering performance: If fragile items are transported, the U-shaped paper corner protectors need to have good buffering performance. You can choose a material with a certain elasticity and toughness, or add a buffer layer to the structural design of the paper corner protectors, such as adding foam, sponge and other materials inside.
