Oxygen Scavenger Mechanism:
Scavenger Compounds neutralize oxygen from in the head space of closed bottles. Additionally, they prevent oxygen ingress into the bottle. Oxygen scavenger material is inserted into the cap as a disc and when exposed to humidity, it is activated to fix oxygen via a chemical reaction. The compound is certified for direct food contact.
Oxygen Scavenger Performance Measurement
Measurement of oxygen ingress into packaging is done using PreSens measuring equipment. In this test, non-invasive oxygen measurement system, a fibre optic trace oxygen transmitter (Fibox 3 trace v3) and sensor spots, are placed inside the bottles before filling and closing. Then oxygen ingress is measured.
Oxygen scavenger performance of SVELOX® 5690 compared to standard material POLYLINER® 569
Parand Machine Co. offers oxygen scavenger SUNCAP® closures in two different versions:
- 28mm PCO1810 cap with PP shell and Oxygen Scavenger liner
- 28mm PCO1810 cap with PE shell and Oxygen Scavenger liner
Thanks to SVELOX® 5690 compound used, our caps provide:
- Enlargement of shelf life as a result of no oxygen ingress up to 100 days
- Reduction of Oxygen ingress in total vs. standard sealant compound
- Superior softness and elasticity for excellent sealing properties on the various returnable bottle finishes of PET and glass
- Suitability for hot filling up to 95 °C with subsequent cooling and pasteurization
- Suitability for beer and fruit juices
- FDA and EU compliance
- Protection of sensitive filling goods
- Outstanding sealing properties
