Olive Oil Aluminum-plastic Caps
Olive oil aluminum-plastic caps combine the aluminum shell with a plastic liner. This dual-material design takes full advantage of the durability and aesthetics of aluminum, as well as the excellent sealing properties of food-grade plastic. These caps are widely used not only for olive oil but also for other liquid products such as vinegar and certain spirits.
Olive oil aluminum-plastic caps are specially designed for sealing olive oil bottles. They combine aluminum and plastic materials to optimize functionality, preservation, and user convenience. These caps are widely used in the food and beverage industry, especially for high-quality products like extra virgin olive oil, where preserving freshness and quality is crucial.
