Metallized Film
Metallized Film
Vacuum-aluminized polyester (PET) film — the raw material that becomes metallic yarn
Metallized film is a composite raw material produced by vacuum-depositing aluminum onto biaxially oriented polyethylene terephthalate (PET) polyester film. It is the core raw material for our metallic yarns (Sim İplik — M, MX, PX, MH and ST types): the film is produced in master rolls and then slit into fine strips that form the finished yarn.
Production process: Under very high vacuum, aluminum is heated and vaporised by resistance-heated ceramic boats, then condensed onto the moving PET film as an atomic layer a few hundred ångströms thick. In an ALU-PET construction, the aluminum layer is laminated between two PET films, so both faces are protected by polyester for maximum colour and brightness durability.
Properties: High brightness and reflectivity, heat resistance, chemical and dimensional stability, and barrier properties against light, moisture, oxygen and gases — along with strong electromagnetic reflection. Standard film thicknesses are 12, 25 and 30 microns; colour options are essentially unlimited (silver, gold, pearl, black, blue, etc.).
Applications: Primarily slit into metallic yarn (Sim İplik). Beyond that, the film is used in luxury packaging, decorative laminations, embroidery and woven embellishment, thermal insulation materials (space-blanket-style) and EMI shielding applications.
