The perfect combination of design, functionality and durability. Capacity 350 ml. About PLA Polylactide, or Polylactic Acid (PLA) is a thermoplastic aliphatic polyester derived from renewable resources. What does this mean? It means that PLA is a biodegradable material made from corn starch produced by plants - natural and renewable. Lactic acid is produced by the fermentation of that corn starch, creating the fibres used to make PLA. This environmentally friendly process converts natural resources into the ideal sustainable material. Each item is supplied in an individual brown cardboard box.
