Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.
Additionally, the sturdiness of large paper bags makes them a practical choice for carrying heavier items. Unlike smaller paper bags, which may not provide sufficient support, large paper bags can safely hold bulkier goods, making them ideal for grocery stores and retail outlets. This functionality adds to their appeal, further driving demand in wholesale markets.
