Screw closures are cost-effective closure solutions with a reliable sealing function. They are used mainly when no additional function to ensure the safety of the contents is necessary, e.g. evidence of tampering. The internal matching mandrel of the closure is tailored to the respective dosing insert, so that pre-assembly can take place without a hitch. The outer appearance of the closure type is identical even when different dosing inserts are installed. Processing can be performed on all commonly encountered filling and sealing systems. In addition to the colour white, we also manufacture to custom specifications.

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.
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.
