Salontea tea domes are made from a plant-based material called polylactic acid (PLA). PLA is an inert, DNA and GMO free material that is produced by breaking down starches found in plant sources such as corn. These starches are broken down into pure lactic acid, and then polymerized through enzymatic activity into long chains of PLA fiber.
PLA-KNIT tea filter material is made by forming PLA fibers into a mesh fabric. We receive the rolls of PLA mesh fabric, and transforms them into pyramid-shaped, whole leaf tea sachets in our tea manufacturing facility.
PLA is used in a wide variety of food products because it is derived from renewable plant sources and is biodegradable in the long term. The conditions under which PLA biodegrades depend on the form that the PLA takes. Our PLA tea bags are designed to biodegrade in commercial quality composting systems, when conditions achieve at least 120°F, and 80% relative humidity. When these conditions are met and held constant, our PLA tea bags will biodegrade over a period of about two months.
Salontea domes have a cotton string and printed-paper tag, which is attached to the PLA mesh using ultrasonic vibrational technology. This process instantly fuses the string to the mesh. The same technique is used when the rolled PLA mesh is spun into a pyramid shape, filled with whole leaf tea, and sealed during production on our tea bagging machine at our manufacturing facility.
