Coated PET Film Description

What Coated PET Film Adds to BOPET

Coated PET film begins with a strong, dimensionally stable BOPET film substrate. A functional layer is applied to one or both surfaces to add performance that standard PET alone cannot provide, including barrier, heat sealability, adhesion, release, or controlled surface properties.

Coating is not the same as corona treatment, coextrusion, metallizing, or lamination. Each process changes PET differently. Clear terminology helps converters select the correct construction, coating side, ink, adhesive, sealing substrate, and downstream process before samples are prepared.

Functional Coating Options for Different Jobs

When shelf life is the priority, PVDC coated PET film provides strong oxygen, moisture, and aroma barrier, while ALOx PET film offers a transparent, chlorine-free alternative. Barrier figures should always be reviewed together with test temperature, relative humidity, and laminate structure.

For printing, adhesive lamination, metallizing, or further functional coating, Chemical Treated PET Film improves surface compatibility and anchorage. For tapes, labels, protective materials, and precision die-cutting, Silicone Coated PET Film provides controlled release with customizable coating sides and release levels.

Where direct sealing is required, Heat Sealable PET Film adds a sealable surface or dedicated sealing layer. If light protection and metallic appearance matter more than transparency, Aluminized PET Film may be a better related solution than a clear coated grade.

Matching Film Performance to the Application

Coating selection should begin with the problem to solve, not only the product name. Buyers should define the packed product, converting process, target shelf life, thickness, width, coating side, and the measurable performance required from the finished structure.

For barrier projects, compare OTR and WVTR under stated conditions rather than relying on general claims. Our guide to oxygen barrier coatings explains how coating chemistry, temperature, humidity, and test methods influence real packaging performance.

The PET base contributes stiffness, heat resistance, print quality, and dimensional stability. These properties make coated grades useful across flexible packaging, lidding, labels, tapes, electronics, and industrial laminates.

Coated PET Film Applications

High-Barrier Food Packaging

PVDC- and AlOx-coated PET films help protect sensitive foods against oxygen, moisture, aroma loss, and premature quality deterioration.

Pharmaceutical and Healthcare Packaging

Functional PET coatings support barrier, cleanliness, dimensional stability, and controlled converting performance for pharmaceutical sachets, diagnostic products, and medical materials.

Tray and Cup Lidding

Heat-sealable coated PET can provide clear, strong lidding for compatible trays and cups when the sealing surface matches the container material.

Printing and Adhesive Lamination

Chemical or primer-coated PET improves compatibility with printing inks, laminating adhesives, metallizing layers, and other downstream coatings.

Labels, Tapes, and Release Liners

Silicone-coated PET provides controlled release, good flatness, and dimensional stability for labels, industrial tapes, protective materials, and precision die-cutting.

Electronics and Industrial Converting

Specialty coated PET is used in electronic components, optical materials, technical laminates, protective constructions, and other precision converting applications.

Four-Step Selection Process

1. Define the Main Function

Determine whether the project primarily needs barrier, sealing, adhesion, release, static control, optical performance, or surface protection.

2. Confirm the Converting Process

Identify whether the film will be printed, adhesively laminated, extrusion laminated, metallized, coated again, die-cut, or directly heat sealed.

3. Establish Measurable Targets

Use measurable requirements such as OTR, WVTR, release force, surface tension, seal strength, sealing temperature, haze, or surface resistance.

4. Test the Finished Structure

Evaluate the selected film together with the actual ink, adhesive, sealant, packed product, machine conditions, and expected distribution environment.

Understanding PET Surface Technologies

Coated PET Film

A liquid, dispersion, resin, oxide, silicone, or other functional material is deposited on the PET surface and dried, cured, or otherwise fixed. The added layer changes one or more surface or barrier properties.

Corona-Treated PET Film

Corona treatment uses electrical discharge to raise the surface energy of PET. It can improve wetting and short-term adhesion but does not create the same functional layer as a chemical, barrier, release, or heat-seal coating.

Coextruded PET Film

A coextruded functional layer is formed together with the PET structure during film production. Coextruded heat-seal layers and post-applied heat-seal coatings should be identified separately because their processing windows may differ.

Metallized PET Film

Metallized PET uses vacuum deposition to place a very thin metal layer on the PET surface. It is closely related to coated film technology but is normally treated as a separate product family.

Laminated PET Film

Laminated PET is bonded to another complete film, foil, paper, or substrate using adhesive or extrusion lamination. A laminate is therefore different from a thin functional coating applied directly to PET.

What is coated PET film?

Coated PET film is a PET or BOPET substrate with a functional material applied to one or both surfaces. The coating can add barrier, heat sealability, adhesion, release, antistatic, optical, tactile, or protective properties.

Is coated PET film the same as chemical treated PET film?

No. Chemical treated PET is one type of coated or surface-modified PET designed mainly to improve adhesion. Coated PET film is a broader product family that also includes barrier, release, heat-seal, and other functional coatings.

What is the difference between coated and corona-treated PET?

A coating deposits a functional material on the PET surface. Corona treatment uses electrical discharge to increase surface energy without adding a separate functional coating. Some PET grades combine both technologies on different sides.

Which coated PET film provides the best barrier?

PVDC-coated PET provides strong oxygen, moisture, and aroma barrier. AlOx PET provides transparent, chlorine-free barrier performance. The correct choice depends on target OTR, WVTR, humidity, processing conditions, regulatory requirements, and laminate design.

Is every coated PET film heat sealable?

No. Only PET grades with a compatible heat-seal coating or sealing layer are designed for direct heat sealing. PVDC, AlOx, chemical, or silicone coatings should not automatically be assumed to provide heat-sealability.

Can coated PET film be printed and laminated?

Many coated PET grades can be printed or laminated, but the correct coating side, ink, adhesive, curing conditions, and surface treatment must be confirmed. Testing is recommended before commercial production.

Can PET film be coated on one or both sides?

Yes. Depending on the grade, PET can have one functional coated side, two similarly coated sides, or different treatments on each side. The winding direction and outward-facing surface should be confirmed before production.

Is coated PET film suitable for food packaging?

Certain grades are available for food-packaging applications. Suitability depends on the coating chemistry, contact position, complete laminate, packed product, processing conditions, and destination-market regulations. Relevant documentation should be confirmed for the selected grade.

Is coated PET film recyclable?

Recyclability depends on the coating type, coating weight, laminate structure, contamination, and local collection system. A PET-based film should not automatically be described as fully recyclable when it is combined with incompatible coatings or other polymers.

What information is required for a quotation?

Please provide the application, required coating function, target performance, thickness, width, roll length or diameter, coating side, printing or lamination process, core size, quantity, destination, and any applicable compliance requirements.
