ELEVES™ Olefin spunbond nonwoven fabric

ELEVES is bi-component composite spunbond nonwoven fabric. Each individual filament has a double-layered structure that the sheath made of polyethylene covers the core made of polyester. The excellent features of these two materials are combined to make this product a high-performance nonwoven fabric sheet that can be used for a vast range of applications.

Features
  • Heat seal offers an outstanding adhesive property.
  • The fabric is as strong as polyester.
  • Excellent water-repellent and lipophilic properties.
  • Proper air and moisture permeability.
  • The fabric can easily be combined with other types of material such as film.
  • Compliant with food and additive standards (Notification No. 370 issued in 1959 by the Ministry of Health and Welfare).
  • Polyester spunbond nonwoven fabric does not easily fray from an edge even when cut.
  • Made of polyethylene and polyester, the material is insusceptible to deterioration due to gamma radiation sterilization.

ELEVES™-II Lower melting point polyethylene is used

ELEVES-II uses lower melting point polyethylene than that of ELEVES as the material for the sheath. This enables heat seal at lower temperature, making it possible to perform heat seal or thermal adhesion with polyethylene film or other material, which has been difficult in the past. Particularly, when thermal adhesion is performed with porous film that has fine holes, sealing at low temperature results in fewer film holes becoming clogged, leading to excellent film performance.

Features
  • While heat seal can be performed at lower temperature than with ELEVES, equally high heat seal strength can be obtained.
  • The fabric is as strong as polyester.
  • Proper air and moisture permeability.
  • The fabric can easily be combined with other types of material such as film.
  • Compliant with food and additive standards (Notification No. 370 issued in 1959 by the Ministry of Health and Welfare).
