Tamper-evident closures
one-part
Easy to open, and the perfect visible protection when your product is first opened. This closure with a contemporary design is the ideal choice for ensuring product safety. Its function of verifying first opening is perfectly discharged when the ring is flawlessly broken off. We manufacture single-piece tamper-evident closures as individual components in a single work step using injection moulding. The tamper-evident ring of the closure is elegantly broken off during the initial opening, after which it remains clearly visible on the bottle shoulder during subsequent use. Clearly recognisable tamper-evident seal, leaving no doubt regarding whether the container has been opened before. Manual closing as well as semi- or fully automatic processing on filling and closing systems is possible.

Sealing systems
Cone seal
A cone seal is the simplest and most inexpensive method for tightly sealing a bottle. During manufacturing, the closure receives a conical sealing lip on the inner side of the cap. Sealing therefore takes place using the closure itself, without the use of a sealing disc. The advantage of this is an inexpensive sealing solution. All closure variants are available with a cone seal.
Sealing discs
When particularly high requirements need to be fulfilled, special disc inserts ensure the indispensable barrier properties for your product. Variants range from simple foam inserts to sophisticated aluminium, Surlyn and Teflon linings, or even RFID inlays.
Heinlein has access to all sealing disc variants. Feel free to contact us.
Tamper-evident closures
multiple-piece
With separately injection-moulded and mounted tamper-evident rings, it offers a user-friendly and particularly dimensionally stable multiple-piece closure solution. The appealing design and a discreet but visible tamper-evident seal provides your product with the required safety against tampering. Seniors will particularly appreciate the comfortable feel and the easy-to-open packaging. Installed in the closure made of robust PP is a separately manufactured tamper-evident safety ring made of HD-PE. This makes the packaging highly resistant to tampering, and fulfils the necessary safety specifications required by the industry. The tamper-evident ring of the closure is broken off cleanly during the initial opening, after which it remains visible on the bottle shoulder during subsequent use. It can be processed on all commonly encountered closing machines.
