The number of paper corner protectors required is usually determined based on factors such as the shape of the product, packaging method, and transportation and storage requirements. The following is a common calculation method:
Paper card board Cylindrical products
The number of paper corner protectors required for a single product: cylindrical products usually use paper corner protectors on the edges of the upper and lower bottom surfaces, and each bottom edge requires 2 paper corner protectors (two opposite points for protection), so a single cylindrical product generally requires 4 paper corner protectors.
Considering the packaging method
Individual packaging: If the product is packaged individually, the number of paper corner protectors required = the number of products × 4. For example, if there are 50 individually packaged cylindrical cans, the number of paper corner protectors required is 50×4 = 200.
Combination packaging of multiple products: When multiple cylindrical products are packaged in combination, the number of corners and the number of paper corner protectors used need to be determined based on the specific combination shape. For example, if 6 cylindrical products are packed in a row, this row of cylinders can be regarded as a whole. The bottom edges of the cylinders at both ends need 2 paper corner protectors each, and the part of the middle cylinder in contact with the adjacent cylinder does not need additional paper corner protectors, so this row of 6 cylindrical products requires 8 paper corner protectors. Then calculate the total number of paper Border protection strip according to the number of rows of combined packaging.
Irregular shaped products
Paper card board Determine the key protection points: For irregular shaped products, it is necessary to first analyze the shape characteristics of the product and find out the key parts that are easily damaged, such as protruding corners, edges, etc. These parts usually need to be protected with paper.
Paper card board Measurement and estimation:Paper card board Measure the length and number of key protection points, and estimate the number of paper corner protectors required for each key protection point based on the specifications of the paper Border protection strip and the actual protection requirements. For example, for an irregular product with 3 protruding corners, each corner needs to be protected with 1 paper Border protection strip, so a single product needs 3 paper Border protection strip. Then calculate the total number of paper Border protection strip based on the number of products, that is, the number of paper Paper card board required = the number of products × the number of paper corner protectors required for each product.
Consider loss and spare
When actually calculating the number of paper Paper card board, you also need to consider a certain amount of loss and spare. Generally speaking, you can add additional paper corner protectors at 5% - 10% of the total demand to deal with possible damage, installation errors, etc. For example, if you calculate that 1,000 paper corner protectors are needed through the above method, then after considering loss and spare, the actual number of paper Paper card board that need to be purchased can be between 1,050 and 1,100.
