Domestic and international standards
With the deepening of China's opening-up policy, more and more goods are exported overseas, and paper drums, as packaging materials, have also realized their own value as goods float across the sea. However, during the transportation of wooden doors in the prosperous era of Wendu, there was also a problem of paper barrel leakage, which is the most serious quality issue of paper barrels and must cause significant damage to the enterprise. The leakage of paper drums is mainly caused by the heavy load and deformation of the drum itself during use or transportation, resulting in the detachment of the drum body from the bottom. This is mainly manifested in the detachment of the bottom of the drum from the connection between the plywood or cardboard, causing item leakage. The main reason is that there are still some problems in the production process, one of which is material issues. The plywood used has an impact on product quality because when plywood is used as the material for the bottom cover of the paper drum, the selected plywood has uneven thickness, and most of the thickness does not meet the requirements. In addition, the adhesive strength between plywood layers is low, which makes it easy to detach from the barrel body. The tolerance of plywood cutting dimensions cannot be accurately controlled. Therefore, in the selection of raw materials, plywood materials that meet the standards should be selected, and the cutting dimensions should be strictly controlled within the tolerance range and quality monitoring should be carried out. The thickness of plywood should be determined based on the maximum weight of the contents of the paper drum. When the weight of the contents of the paper drum is around 50 kilograms, the thickness of plywood should not be less than 6 millimeters. The second issue is the production equipment for paper barrels. The connection between the barrel body and the barrel bottom in the production process of paper barrels mainly relies on the bottom sealing forming process. Therefore, the operation of the equipment for forming and sealing the bottom will affect the overall quality of the paper barrel. The size changes of each part of the bottom sealing mold should be regularly checked for the operation of the equipment, because when the mold closes the bottom of the paper barrel, the vertical plane of the locking ring mold is prone to deviation, resulting in uneven tightness of the bottom of the paper barrel, which affects the degree of fit between the barrel bottom and the barrel body.
