FEAUTURE
■Resin Products: Medical-grade compounds (Zelas™) are used for packaging medical devices and pharmaceuticals.
It is formulated with a specific blend in mind.
■Zelas™ has high drug hygiene properties and is used as a material for pharmaceutical packaging and medication dispensing devices.
It has been in use for many years.
■Olefin-based elastomer type Zelas™TPO is based on our proprietary reactor TPO,
We offer grades suitable for each layer of medical soft bags: the inner layer, the middle layer/adhesive layer, and the outer layer.
