Oxygen Block/scavenger Masterbatch
Oxygen causes oxidation and promotes the enzymatic and non-enzymatic phenolic browning of fresh fruit and the growth of microorganisms. Packaging without or with less extends shelf-life and inhibits deterioration. Therefore, using oxygen scavenger or oxygen block polymeric masterbatch can extend shelf-life of the packaged food.
Polysharif-O2Block Masterbatch can be employed in food packag-ing as trays and flexible films. The base of the masterbatch is low density polyethylene (LDPE) or polyamide (PA).
The O2block masterbatch is added during the melt processing of the final product in the range of 1 to 10 wt.%, depends on the application and type of the products. Utilizing this product, the oxygen transmission rate (OTR) of the polymeric film can be reduced dramatically. The OTR properties of the film and solid container can be evaluated according to ISO 15015-2:2003. According to the standards, the OTR value is less than 100 cc/m2/24 hr. The masterbatch is FDA approved and contains clay nano-materials and Iron compounds.
- Ease of processing for any blown and extruded film products,
- Without any change in processing parameters,
- OTR less than 100 cc/m2/24
- Low cost and affordability
