Bottle mouth type: Different bottle mouth designs are suitable for different usage scenarios. Wide mouthed bottles are convenient for filling and retrieving products, suitable for jams, canned goods, and other products; Narrow mouthed bottles are beneficial for controlling the outflow of liquids and are commonly used for packaging liquid products such as beverages and oral liquids. In addition, the accuracy of the bottle mouth is also important to ensure a tight fit with the bottle cap and ensure sealing.
