OPS is the universal abbreviationof BIAXIAL ORIENTED POLYSTYRENE, which is a new type of polymerenvironmental friendly packaging material.

BOPS is a sheet made bythe flat die extrusion, having a tree-layer structure – A/B/A.Superb mechanical and optical properties of the sheet are theresult of the biaxial orientation of high-molecularpolystyrene.

The BOPS rigid film hasno taste or odder, having a range of significant advantages,namely, outstanding thermoforming processability, high consumerproperties of the final packaging product.

Application: blister packaging, clam shells,trays, box inserts, bakery, salads and other thermoformingcontainers.

BOPS advantages:

• low specific gravity, 1.05g/cm³;
• high rigidity, tearresistance;
• superb clarity, spark andgloss;
• low processing costs;
• silicone coating - easier moldremoval and stack nesting/denesting;
• higher processingoutput;
• processing universality atdifferent equipment;
• decoration: metallization,masterbatch coloring;
• antifog coating as anoption.
