Membrane/Film Creation

The Membrane/Film Creation production stage is only applicable to laminate material types. There are four process options that are available for all laminate materials:

  • Extrusion on carrier should be selected when the raw material is melted and extruded onto a release paper carrier to form a film or membrane. The release paper is removed and the film or membrane can be used as-is or can be bonded to a different substrate.
  • Extrusion without carrier should be selected when the raw material is melted and extruded into a film or membrane directly with no release paper, such as in direct extrusion and bonding onto a textile substrate.
  • Solvent solution on carrier should be selected when the raw material is dissolved in an organic solvent before being poured onto a carrier. The membrane or film is formed by evaporating the solvent through the application of heat.
  • Water based solution on carrier should be selected when the raw material is dissolved primarily in water before being poured onto a carrier. The membrane or film is formed by evaporating the water and other solvents through the application of heat.

If the specific membrane creation process is not known, then the default selection of extrusion without carrier should be left unchanged.
