ROPP Cap for Small Jar and Bottle

Last Updated :Apr. 10, 2024

In the packaging world, the importance of sealing solutions cannot be overstated. Whether it is food, beverages, pharmaceuticals or cosmetics, ensuring product integrity and freshness is crucial. ROPP (Rolling Ball Anti-Theft) bottle caps are one solution that has gained widespread recognition for their efficacy and versatility.

ROPP lids are a closure mechanism designed to provide tamper resistance and ensure product integrity. These lids consist of an aluminum shell with a thread pattern on the inside that matches the neck finish of the container. The lid is sealed to the container by rolling the lid onto the container using specialized machinery, hence the name "roll-on theft proof".

The construction of a ROPP bottle cap consists of several key components, including the shell, liner, and anti-theft tape. The casing is usually made of aluminum, which provides durability and barrier properties to protect the contents from external factors such as moisture and oxygen. The liner, usually made of plastic or foam, creates a tight seal between the lid and container, preventing leakage and contamination. An anti-tamper tape located at the base of the cap ensures tamper resistance by breaking upon initial opening, indicating that the product may have been stolen.

ROPP small jar caps are mostly processed on production lines with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the material are very strict, otherwise breaks or creases will occur during the processing. In order to ensure that the ROPP small jar caps are easy to print after being formed, the ROPP small jar caps are required to have a smooth surface without rolling marks, scratches or stains. Generally, 8011-H14 and 3003-H16 are used in alloy state. Material specifications generally have a thickness of 0.20mm-0.23mm and a width of 449mm-796mm. The production of ROPP caps for small cans and vials can be done by hot rolling or continuous casting and rolling respectively. At present, my country's anti-theft covering material production plants mostly use continuous casting and rolling processes, and their performance is better than that of casting and rolling processes.
