Coffee Capsule Injection Compound (95C, FDA)

About This Product

A heat-modified polylactic acid compound, supplied as a pellet for injection moulding. The base polyester is produced by ring-opening polymerisation of lactide derived from fermented plant sugars, then compounded and nucleated so that the moulded part keeps its geometry well above the point at which unmodified PLA softens. It is supplied FDA compliant for food contact. A coffee capsule faces near-boiling water under pressure for the length of the extraction. Most compostable polymers deform well below that. This grade is rated to 95C specifically for the application. In a PLA system that rating comes from crystallinity rather than additives alone: amorphous material softens at the glass transition while crystalline domains hold the wall rigid far above it, so nucleation, mould temperature and hold time in your cycle decide whether the rated performance is developed in the part. The capsule also has to hold a seal and puncture cleanly, and the barrier requirement for coffee freshness is usually met by a separate lidding or barrier layer rather than by the body resin alone. Supplied as a raw material for processing on the buyer's own line. We do not produce finished articles. It is used in single-serve coffee capsules, hot beverage systems and food packaging. Bio Green Chem supplies this coffee capsule injection compound to specification on polymer base, pellet form, melt flow, the 95C heat rating and FDA food-contact compliance.
