Food Cling Film Compound (PLA/PBAT, FDA)

About This Product

The compound is an FDA-compliant film-grade pellet blend of polylactic acid and polybutylene adipate terephthalate, formulated for the cling and conformability a wrapping film depends on. It is supplied for blown film production on the converter's existing line. Cling film is a difficult specification: the film has to adhere to itself and to a container rim, stretch without tearing, and remain compliant for direct food contact. Cling is not adhesion in the glue sense but short-range intermolecular attraction, and it acts only where two surfaces are in genuinely intimate contact, so the film must be soft enough to flow into the roughness of a bowl rim under nothing more than finger pressure. That runs against PLA, the stiff, high-modulus half of the blend and the half that holds a fold rather than draping into one. The formulation has to soften and toughen the PLA far enough to conform and to stretch over a rim without tearing at a very thin gauge, while keeping every component inside the food-contact scope, which narrows the options. Cling performance, gauge and the exact food-contact documentation are confirmed against the intended use before supply. It is used in food cling film, catering and foodservice wrap, retail food wrapping and blown film conversion. Bio Green Chem supplies the food cling film compound to specification on PLA/PBAT ratio, melt flow, film gauge, cling performance and the documentation required, as a raw material for processing on the buyer's own line; we do not produce finished articles.
