Pick UpMITSUI PELLICLE™ : World-leading dust cover for Photomask
Employed in the exposure process that facilitates the production of semiconductors, LCD panels and more, photomask pellicles serve as a protective cover for intricately patterned photomasks, preventing dust from attaching to the photomask and affecting the imaging on the silicon wafer or glass substrate.
We contribute to customers' productivity improvement not only by designing materials and products, but also by providing services based on our experience and technology.
Imaging solutions
Pick UpAPEL™ : Transparent resin for high performance lenses
APEL™ is a cyclic olefin copolymer used in the camera lenses of smartphones. With a high refractive index and low birefringence, APEL™ can be used in place of glass for optical lens applications, facilitating the design of smaller, lighter products
APEL™ also has excellent moisture-proof properties, resistance to chemicals and non-attachment characteristics, it is used for medical packaging material.

L-LDPE film (T.U.X™), resource-saving and environmentally friendly L-LDPE film (L-Smart™),
heat sealant for environmentally friendly paper packaging materials (CHEMIPEARL™),
barrier coating materials ( TAKELAC™ WPB ), packaging adhesives (TAKENATE™ & TAKELAC™)
Pick UpCHEMIPEARL™ : Polyolefin-based Aqueous Dispersion
CHEMIPEARL™ is a polyolefin-based aqueous dispersion developed by Mitsui Chemicals' unique technology.
It provides heat-sealing property, water-resistance and oil-resistance to paper by coating and could be used for various types of paper packaging material including food packaging.
CHEMIPEARL™ coated paper can reduce usage of plastic and it is easily crushable and becoming pulp slurry compared to PE-laminated paper.
