Bottle sealing is the process of securely closing a bottle to prevent contamination, leakage, or spoilage of its contents. This is commonly done using various methods, such as corking for wine bottles, screwing on caps for soft drinks, or applying heat to shrink wrap for sauces. Effective sealing ensures that the product remains fresh and safe for consumption. Different industries utilize specific sealing techniques based on the type of liquid and bottle design. For example, glass bottles often use corks or metal caps, while plastic bottles typically feature screw-on lids. Proper sealing is essential for maintaining product quality and extending shelf life.
