Manufacturing Process Overview
The polyester films production operation transforms PET resin, whether polymerised on-site from purified terephthalic acid and ethylene glycol or procured as film-grade chips, into thin, biaxially oriented film through a sequence of chip preparation, extrusion, orientation, finishing, and packaging operations. The key process stages are:
- PET Resin Preparation: Where backward integration is pursued, purified terephthalic acid (PTA) and monoethylene glycol (MEG) undergo esterification followed by polycondensation under vacuum and heat to form high-viscosity PET resin, which is chipped, crystallised, and dried to the moisture and intrinsic viscosity specification required for film-grade extrusion. Where PET chips are purchased externally, this stage is limited to chip drying and quality verification prior to extrusion.
- Extrusion and Casting: Dried PET chips are melted in a screw extruder, filtered to remove contaminants and gels, and extruded through a flat die onto a rotating chill roll to form an amorphous, unoriented cast sheet with uniform thickness and clarity.
- Machine Direction Orientation (MDO): The cast sheet is reheated and stretched in the direction of film travel between differential-speed rollers, aligning polymer chains along the machine direction and developing initial tensile strength.
- Transverse Direction Orientation (TDO): The machine-direction-oriented film enters a tenter frame where it is gripped at the edges and stretched perpendicular to the direction of travel under controlled heat, biaxially orienting the polymer structure to achieve the target strength, clarity, and barrier properties characteristic of BOPET film.
- Heat Setting and Annealing: The biaxially oriented film is thermally stabilised in an in-line oven under controlled tension to relieve internal stresses and limit shrinkage, ensuring dimensional stability during downstream converting and end-use applications.
- Surface Treatment and Coating: Depending on the target application, the film may undergo corona treatment to improve print and adhesive bonding, or be coated or metallised to impart anti-static, anti-fog, barrier, or reflective functional properties.
- Thickness Gauging and Quality Inspection: In-line beta gauges and optical inspection systems continuously monitor film thickness, uniformity and surface quality across the full film width, flagging deviations for corrective action or rejection.
- Slitting: The finished master roll is precision-slit into narrower rolls of specified width in accordance with converter and customer order requirements.
- Winding and Core Preparation: Slit film is wound onto cores under controlled tension to produce finished rolls free of wrinkles, telescoping, or winding defects.
- Quality Control: Finished film is tested for tensile strength, dielectric strength, haze and clarity, shrinkage, and thickness uniformity to verify compliance with application-specific customer and industry quality standards before release for despatch.
- Packaging and Dispatch: Finished film rolls are wrapped, labelled, and palletised for despatch to flexible packaging converters, electronics component manufacturers, solar module producers, and industrial laminators.
