Biomax® Strong 120 is an ethylene copolymer designed to modify Polylactic Acid (PLA) for improved toughness properties in packaging and industrial applications. Some of the attributes of Biomax® Strong 120 in PLA include:
- Special Chemistry for PLA. Even small amounts provide toughness benefits;
- Engineered for PLA, rapid melt-dispersion, even with single screw extruders;
- Pelletized, efficient extruder feeding; separately or as a pellet-bend with PLA;
Blends containing 5% (wt.) or less modifier maintain contact clarity similar to clarified Polypropylene (PP), while blends in the 5 - 15% range presents different degrees of translucence, similar to unclarified PP.
Biomax® Strong 120 is similar to Biomax® Strong 100 but is designed for food packaging applications subject to the regulatory requirements detailed below.
Impact strength of BIOMAX® Strong 120 modified PLA, both in the amorphous and crystalline estates, is significantly improved even at 2wt% addition level.
BIOMAX® Strong 120 greatly improves the cutting & trimming of PLA 3001 & 2002. While unmodified PLA 3001 & 2002 exhibits breakage at the edge of the sheet, blends with 2 to 5 wt.% of BIOMAX® Strong 120 show no breakage. There is also a marked improvement of "pinning". While unmodified PLA 3001 breaks at the edge of the sheet, there is no breakage once BIOMAX® Strong 120 is added.
