Pet polyester film price

The price is primarily driven by thickness (measured in microns/μm), optical clarity, and surface treatment. Standard packaging films (12-50μm) are generally cheaper, while ultra-thin (under 6μm) or thick electrical grade films command a premium. Additionally, specialized treatments like Corona treatment, chemical coating (primed), or metallization will increase the base price due to additional processing costs.

Buyers must distinguish between Virgin Grade and Recycled (rPET) Grade materials; virgin resin offers better tensile strength and clarity but at a higher cost. For food packaging or medical applications, ensure the film meets FDA, EC 10/2011, or REACH compliance, as certified food-grade materials involve stricter production environments and higher quality control overheads.

To ensure value for money, request lab reports for Tensile Strength (MD/TD), Shrinkage Rate (critical for heat-sealing), and Haze/Transparency levels. For industrial applications, the Dielectric Strength and Coefficient of Friction (COF) are vital to ensure the film runs smoothly on high-speed conversion machinery without tearing or static buildup.

Usage scenarios vary widely: Flexible Packaging requires high barrier properties; Solar Backsheets require UV resistance and long-term hydrolysis resistance; and Electronic Displays require optical grade film with zero defects. Selecting a film 'over-specced' for your application leads to unnecessary costs, while 'under-speccing' leads to product failure.

The most common risks include moisture damage during sea transit and core deformation. PET film is hygroscopic; if not packed with desiccant and moisture-proof foil, it can degrade. Furthermore, ensure the supplier uses heavy-duty suspended packaging (end-bracket packing) to prevent the rolls from developing 'flat spots' due to their own weight during long-term shipping.

Leverage volume-based pricing by consolidating orders to meet full container loads (FCL), which significantly reduces the per-unit shipping cost. Since PET is a petroleum-based product, prices fluctuate with raw material (PTA/MEG) market trends. Negotiate a formula-based pricing agreement or lock in prices during market dips. For reliable sourcing, platforms like Made-in-China.com allow you to compare 'Diamond Members' who have undergone audited supplier checks.

Always use Trade Assurance or Letters of Credit (L/C) for initial high-value transactions. Before the final payment, hire a third-party inspection agency (like SGS or Intertek) to perform a 'Random Sampling' at the factory to verify roll length, width, and thickness consistency against the Proforma Invoice. Never release full payment until the Bill of Lading (B/L) is confirmed and quality is verified.

Check the HS Code (typically 3920.62) for specific import duties in your country. Be aware of Anti-Dumping Duties (ADD) that some regions (like the EU or USA) may impose on PET films from specific origins. Ensure the supplier provides a Certificate of Origin to benefit from any applicable Free Trade Agreements (FTA) that could reduce your customs burden.
