With a total of five patents to his name, Saito's latest inventions showcase his expertise and dedication to advancing the industry.

Latest Patents

Saito's most recent patents include a "Heat-sealable crosslinked oriented polyethylene film and production" and a "Differentially crosslinked and oriented polyethylene film." The first patent describes a heat-sealable crosslinked oriented polyethylene film that boasts low-temperature heat sealability, facilitating high-speed bag making. Saito's film improves antiblocking properties while maintaining exceptional clarity and moistureproofness. It features a crosslinked, biaxially oriented high-density polyethylene film with varying degrees of crosslinking across its thickness, complemented by a heat sealing layer made from a tackifier and an ethylene-vinyl acetate copolymer, among other components.

The second patent outlines a method for preparing an oriented film through crosslinking a sheet of high-density polyethylene (HDPE). This process ensures maximum crosslinking at the sheet's surfaces while maintaining minimal orientation in the middle layer, resulting in a film of high clarity and enhanced moisture resistance through subsequent heating and stretching.
