28mm Black plastic screw cap with internal shutter and tamper-evident seal. The shutter is integrated inside the lid, it is made of low density polyethylene plastic (LDPE or PELD), and it guarantees a more hermetic locking. It has an internal plug that is integrated inside the cap itself for a better fit with the neck of the bottle and to ensure a leak-free closure. Polyethylene closure for PP28 Pilfer 28, DIN28 or GL28 screw bottles. The closure is threaded and sealed.

White lid with tamper-evident seal and a Teflon (PTFE) inner disc for PP28 screw-on glass bottles. This cap is designed specifically for PP28 threaded glass jars, offering a secure and reliable closure for a variety of uses. Manufactured from polyethylene (PP) plastic for durability and chemical resistance. The tamper-evident closure system ensures that the container has not been tampered with or previously opened. When the cap is screwed on, the seal is sealed, and when opened for the first time, the tamper-evident ring remains on the neck of the bottle as evidence of opening. It includes a Teflon (PTFE) disc that ensures a tight seal and additional protection against leakage and contamination, ideal for sensitive products. This closure is an ideal choice for applications where safety, content integrity and chemical resistance are required, such as in the pharmaceutical, chemical, food, and cosmetics industries.
