Aluminum caps are used to close glass bottles that are filled with mineral and natural waters, non-alcoholic and alcoholic beverages, pharmaceutical and technical contents. The fasteners are packed in polyethylene bags and five-layer cardboard boxes. The packaging method prevents contamination of the closure. Sealers have a certificate of health and safety in contact with food. They are supplied with a liner made of expanded polyethylene or with a dosing safety valve. Aluminum stel-cap closures are used to close glass bottles that are filled with alcoholic beverages, wines and other contents for the food industry. In addition to standard offset and lateral dry offset printing, hot foil and embossing techniques are used for the decoration and superior appearance of these closures. In this way, we have enabled all producers of wine, vodka, liqueurs and other alcoholic and non-alcoholic beverages to present their brands in a unique way.
