With decades of experience in masterbatches for BOPP film and PE blown film applications, Ampacet has introduced BIAX4CE™ masterbatch portfolio specifically designed for BOPE film.

Mono-material packaging is preferred to multi-material packaging to meet recycling targets set by the EU for plastic packaging and boost the quality of mechanically-recycled material.

Because the polypropylene (PP) recycling stream does not exist at scale in many countries and the polyethylene (PE) recycling stream is prevalent, the development of biaxially-oriented polyethylene (BOPE) film applications is emerging. BOPE film production also benefits from idle capacity on existing biaxially-oriented polypropylene (BOPP) film manufacturing equipment, requiring only an adjustment in processing conditions with no major machinery changes.

In laminated packaging structures, BOPE film allows substitution of some non-polyethylene substrates such as BOPP, BOPA, BOPET and CPP in the manufacture of mono-material PE packaging, leading to an improvement in the quality of the mechanically recycled PE stream, while requiring compromises on some packaging functionalities such as lower stiffness, gloss and gas barrier characteristics. BOPE structures present advantages over BOPP, including greater seal strength, improved packaging seal integrity and better puncture resistance. BOPE also has proven superior to PE blown films in down-gauging, higher output and yield, better optics and tighter gauge control.

Ampacet BIAX4CE masterbatch portfolio includes additive as well as white masterbatches formulated to meet optimum quality and processing requirements for specific BOPE film structures.

The Ampacet BIAX4CE additive range includes antiblock, antistatic, migrating and non-migrating slip as well as high performance antifog masterbatches.
