nowadays fibre drum Packaging has been popular in the export field for more than ten years, and various doubts that once existed have disappeared under the test of time. The quality of paper barrel manufacturers has been recognized and loved by merchants from all over the world. However, to this day, many merchants who have just started to use paper barrels still have doubts about the waterproof performance of paper barrel packaging.

The common sense that paper is easily soaked in water is the biggest obstacle to customers accepting that paper drums can be waterproof. In the inspection quality requirements for paper drum exports, the second item clearly stipulates that the drum body should be smooth, without mechanical damage, wrinkles, or glue peeling, the waterproof paint should be evenly applied, without omissions, bubbles, or obvious sagging. This one shows that the surface of the paper bucket is coated with waterproof paint. Many waterproof paints here are designed to prevent the paper bucket from being soaked by rainwater, but to consider that the paint on the paper bucket will be washed away by rainwater in a rainy state. The potential prerequisite for this requirement is that the paper bucket can withstand the test of rainwater.

With the development of technology, research on paper products has become increasingly in-depth, and various types of paper materials have emerged one after another. The usual paper barrel is made of eight layers of kraft paper and glued together with polyvinyl alcohol solution. For kraft paper, waterproofness is its own characteristic, let alone the use of eight layers of kraft paper. Coupled with the protection of waterproof agents and paint, the waterproof performance is not inferior to other packaging materials. If we want to trace the origin, the ancient oil paper umbrella is the best proof of paper waterproofing. Therefore, paper drums can fully meet the requirements of waterproofing. Currently, the main factor that hinders the continued development of paper drums is the limitation of materials. For paper drums, leakage is the biggest problem. When the loaded items exceed the maximum bearing capacity of the paper drum, the bottom of the paper drum is prone to fall off, causing losses to the merchant. Currently, only controlling the bearing capacity and adding iron hoops at the bottom of the paper drum can be used for protection.
