PP28 threaded caps with tamper-evident safety system are closing solutions designed to guarantee sealing, protection, and versatility in laboratory, cosmetic, and industry packaging. Manufactured from polypropylene (PP), they offer excellent chemical and thermal resistance, allowing sterilization up to 120 °C without compromising their properties.
These caps incorporate a safety ring that detaches upon first opening, remaining fixed to the neck of the container and indicating any previous manipulation. This system ensures product integrity during storage and transport.
They are compatible with multiple 28 mm thread standards, including PP28, Pilfer 28, DIN28, and GL28, allowing their use with a wide range of jars and bottles.
The internal sealing system may vary depending on the model, adapting to different technical needs:
• Integrated obturator (LDPE): provides a precise fit when inserted into the neck of the container, improving sealing.
• PTFE disc: offers superior chemical resistance, especially indicated for aggressive or sensitive substances.
• EPE disc: acts as a sealing gasket, improving impermeability and reducing the risk of leaks.
The closure is applied manually, without the need for tools, which facilitates its use in dynamic work environments. Furthermore, they are available in multiple colors, allowing for efficient visual identification.
These caps constitute a reliable and adaptable solution for securing containers in sectors such as laboratory, chemical, pharmaceutical, cosmetic, and food industries, guaranteeing protection, functionality, and safety in every application.
