Biaxially oriented PET film has excellent clarity and semicrystalline structure. It is made from PET and is heat-set to lock the molecular orientation in the film plane. The resulting film has a typical Young's modulus of 4 GPa. During the biaxial orientation process, numerous crystal nuclei form. Crystallites are particles less than one micron in size.
Biaxially oriented polystyrene film is available in matte and high gloss white. It is also available with optional corona treatment on one or both sides. It is FDA compliant and can be produced in a wide range of thicknesses. This makes it ideal for packaging small and medium-sized food products.
PET Film is an excellent barrier material. It can effectively block light and gas, while providing superior tear and heat resistance. It is also less susceptible to corrosion than pure aluminum foil. Its versatility makes it ideal for food packaging and other specialty applications. Metalized PET Film is especially useful for applications where the preservation of flavour and aroma is important.
Available in 0.5 to eight millimeter thickness, metalized polyester films have a wide range of applications. They are lightweight, flexibly coated, anti-static, reflective, waterproof, and temperature resistant. They can be customized to meet customer specifications. It is also available in various color varieties.
Aluminized PET film is often a suitable substitute for aluminium foil. Its higher gloss level and metallised appearance allow for greater protection and barrier properties. These advantages make metallized PET film the ideal choice for a wide range of applications. The film is also compatible with printing processes.
Metallic PET Films are also useful for applications where temperature control is crucial. These films offer thermal insulation, especially for low-temperature applications. In addition, they are excellent electromagnetic radiation barriers. Aluminized PET films reflect UV, visible, and infrared light. While gold and silver are excellent at reflecting light, aluminum has a high reflectivity regardless of wavelength.
