Japan-based airlaid producer Kinsei Seishi uses tea leaves, coffee beans and orange peels as raw materials for its nonwovens production. In addition to wipes and diaper components, the company’s airlaid products are used as absorbent pads for meat trays and also as protective packaging for fruit and vegetables.

The company has also introduced double-sided nonwoven wipes to its domestic Japanese markets under the brand Natural Cleaning, containing either sodium bicarbonate (baking soda) or citric acid as replacements for detergents. The nonwoven wipe has a degree of water solubility and the solution it contains is weakly alkaline, with a pH of 8.2.

Kinsei Seishi’s Ecopal technology is capable of manufacturing airlaid nonwovens in an 8-100 gpsm weight range with multiple layers and engineered density gradients as required.

The company operates factories in Kochi and Hidakamura. Over the years, Kinsei Seishi has gradually expanded its capacity for recycling PET bottles into fibers as the basis of many of its nonwovens, such as bags, wipes, vacuum cleaner bags and fan filters.
