《The Transformation of Paper Can Rim Flanging: Three Diagrams Revealing Different Forms and Sealing Mysteries》
Whether the paper can is flanged matters a lot. Without flanging, the lid will lift up when placed, failing to fit properly. However, after flanging, the lid can closely adhere to the flange, ensuring a tight fit, effectively preventing lifting and guaranteeing the can’s sealing effect for more worry – free storage.
《Comparison of Effects Before and After Paper Can Flanging: Demonstrating Process Differences and Changes in Sealing》
The flaring of paper cans is for better sealing. If the size of the paper can doesn’t match that of the lid, the sealing effect will be affected. Flaring can change the shape of the paper can’s mouth, increasing the contact area with the lid, thus achieving a tight fit. This can effectively prevent external air, moisture, etc. from entering the can and protect the contents. For example, when packaging food, it can avoid food spoilage; when packaging cosmetics, it can prevent their quality from being affected. At the same time, the structure after flaring is more stable and is not prone to deformation during transportation and other processes, and can continuously maintain a good sealing state to ensure the safety of the items in the can. This is an important reason why paper cans need to be flared.
