PET Films

BOPET (Biaxially Oriented Polyethylene Terephthalate) film has excellent physical properties and is used for a wide variety of products.

BOPET film represent the second largest segment (by volume) in the biaxially oriented film market. BOPET is used as plain, co-extruded, or quite often inline coated, treated, clear, pigmented or matte film in:
• Packaging
• Industrial and special applications
• Electrical
• Imaging
• Decoration

Characteristics and applications Polyester Film Features and Benefits:

Biaxially oriented PET film (BOPET) is used successfully in a wide range of applications, due to its excellent combination of optical, physical, mechanical, thermal, and chemical properties, as well as its unique versatility.
Optically brilliant, clear appearance
Unequaled mechanical strength and toughness
Excellent dielectric properties
Good flatness and coefficient of friction (COF)
Tear-resistant and puncture-resistant characteristics
Wide range of thicknesses-as thin as 1 micron up to 350 micron
Excellent dimensional stability over a wide range of temperatures
Very good resistance to most common solvents, moisture, oil, and grease
Excellent barrier against a wide range of gases

Applications:

Packaging
BOPET’s appeal for packaging applications is its thermal stability; chemical resistance; oxygen and water barrier (with surface coating); clarity; shrinkability; good adhesion for coatings, inks, and metals; and its sealability. The material is ideal for stand-up pouches, lids, peelable seals, microwavable food packaging, metallized high barrier packaging, can lamination, labels, gift wrapping and holographic packaging.

Industrial
In industry, BOPET is applied as a glass protection layer, sheet metal protection, adhesive tapes and films, sails, thermal insulation, emergency blankets, X-ray films, and visual and telescopic solar filters. BOPET has high thermal and moisture dimensional stability, broad light transmission, high tensile strength, and chemical resistance.

Electrical
Because of its dimensional stability, high dielectric constant, and coefficient of friction, BOPET film (either by itself or laminated with other materials) is ideal for many electrical applications such as capacitors, motor insulation, cable and wire barriers, conductor wrapping, insulation for solar panels, functional layers in LCD displays, loudspeaker diaphragms, and base material for flexible PC boards.

Graphic design
The excellent optical and surface properties, non-aging qualities, and long shelf life make BOPET the preferred material for applications such as decorative panels, backlights, roll signs, microfilms, drafting/reprographics, plots and drawings, map overlays, and laminates.

Decoration
Due to its clarity, transparency, and thermal stability, BOPET is used for decoration or numbering on textiles, papers and plastics through hot stamping and thermo transfer processes. BOPET is also used for metallized and/or coated decorative yarns and confetti.

TRANSPARENT CORONA TREATED
‘The corona treated surface provides excellent adhesion to printing inks and laminating adhesives. Coatings has direct adhesion to the PET surface. It is suggested for general packaging applications.
Thicknesses options from 8 to 50 microns

TRANSPARENT CHEMICALLY TREATED
– Copolymer coating
– Acrylic coating
– Special coating for Hot Filling Applications

These are transparent biaxially oriented polyester (BOPET) films with one side chemically coated to give excellent adhesion to wide range of inks and lamination adhesives. It has a very high and stable wetting tension level for extended time periods due to chemical coating.

TRANSPARENT – COEXTRUDED

Transparent biaxially oriented polyester films (BOPET) with a functional layer of copolyester on one side. The modified layer has excellent compatibility with most inks, adhesives, coatings, primers, etc., and also ensures high metal bonding strength after metallization. Thickness options from 12 to 30 microns.

TRANSPARENT – COATED

  • PVDC coating.

METALLIZED

  • Metallized with corona treatment.
  • Metallized with chemical treatment.
  • Metallized with coextruded copolymer.
  • High-barrier metallized.
  • Metallized with strong metal anchoring.

Vacuum-metallized biaxially oriented polyester films exhibit excellent barrier properties and high gloss. The base film used may have different options to enhance metal adhesion to the film. Thickness options from 8 to 50 microns.
