Olive oil Caps

The oil cap usually contains food-grade oil (such as mineral oil) inside, which can effectively enhance the sealing performance, prevent air from entering and the evaporation of wine, and maintain the flavor and quality of the wine.

The oil layer of the oil cap can isolate the air, reduce the contact between wine and oxygen, prevent oxidation, and extend the shelf life of the wine.

The oil inside the oil cap has a lubricating effect, making the opening and closing of the bottle cap smoother and improving the user experience.

Some oil caps are complex in design and have anti-counterfeiting functions to prevent the emergence of counterfeit and inferior products.

The oil cap is usually made of high-quality metal or plastic, wear-resistant, and can be used multiple times.

The oil used in the oil cap is usually food-grade, safe and non-toxic. Some designs also consider environmental factors and use recyclable materials.

The surface of the oil cap can be processed in a variety of ways, such as brushing, polishing, printing, etc., to enhance the product appearance and brand image.
