Plastic closures are used for sealing of bottle of liquid as well as carbonated soft drink. In case of the latter ,that is ,drinks which have a lot of fizz owing to carbon dioxide, it is very necessary for the bottles to have a closure or a cap which would retain the fizz ( i,e, the gas inside ) for a reasonable number of days.
In case of plastic closures, used for other liquids, these closures give a very elegant look and because of good manufacturing process are completely tamper proof, but easy to open.
The closures that we produce is a two piece closure, as there is a TPE ( Thermo Plastic Elastomer) separate liner, with a “lip” profile that exactly matches the bottle lip. The process of manufacturing is by first compression molding (it adds more strength than other processes ) and then lining. The other aspect is our process of manufacturing of this two piece closure ensures gas retention for soft / carbonated beverages.
