PET sequin film

When sourcing PET Sequin Film, you must prioritize thickness (typically 25μm to 150μm) and heat resistance, as the film must withstand high temperatures during the punching or garment pressing process without warping. Ensure the film has high tensile strength to prevent tearing during high-speed sequin punching. Additionally, verify the colorfastness rating (Grade 4 or higher) to ensure the metallic or holographic finish does not fade after washing or exposure to UV light.

Compatibility depends on the roll width and core diameter required by your sequin punching machines. Most industrial machines require a standard 3-inch (76mm) paper core. You should also confirm the surface tension (dyne level) if you plan to perform secondary printing or coating, ensuring the ink or adhesive bonds correctly to the PET substrate.

For international trade, especially to the EU and US, the film must be REACH and RoHS compliant to ensure it is free from heavy metals and harmful phthalates. If the sequins are intended for children's apparel, they must meet CPSIA standards. Always request OEKO-TEX Standard 100 certification from the supplier to guarantee the film is safe for skin contact in textile applications.

Holographic and Laser films are primarily used for high-fashion evening wear and stage costumes to maximize light reflection. Matte or Opaque PET films are better suited for everyday apparel and accessories where a subtle texture is desired. For industrial use, such as automotive interiors or home textiles, ensure the film has enhanced abrasion resistance to handle frequent friction.

Always request a pre-production sample and conduct a 'wash test' and 'heat press test' before placing a bulk order. Use third-party inspection services to verify the coating uniformity and check for 'pinholes' or color variations between batches. For secure transactions, utilize the secured payment services on Made-in-China.com to ensure funds are only released upon proof of shipment.

Negotiate based on Total Volume Commitment rather than a single order to secure 'Tier 1' pricing. Ask for customized roll lengths to reduce scrap waste in your factory, which effectively lowers your net cost. If you are a long-term buyer, negotiate for free replacement of defective rolls (usually a 1-3% defect allowance is standard in the industry).

PET Sequin Film is sensitive to pressure and moisture. Ensure the supplier uses vertical pallet packaging with protective edge boards to prevent 'flat spots' on the rolls. Specify the use of desiccant silica gel packs inside the moisture-proof plastic wrapping to prevent oxidation of metallic coatings during long-term sea freight.

Confirm the correct HS Code (typically 3920.62 for PET plates/film) with your customs broker to avoid misclassification penalties. Be aware of anti-dumping duties that some countries impose on polyester products from specific regions. Ensure the Certificate of Origin is provided to take advantage of any applicable Free Trade Agreements (FTA) that could reduce your import tariffs.
