4.5Microns B-Grade BOPET Film: Cost-Effective TTR & Lamination Base

4.5Microns BOPET Film for printing & laminating

4.5Mic B-Grade BOPET films, which are a strategic choice for cost-sensitive applications where the extreme precision of A-grade material isn't strictly necessary, the 4.5 Micron B-Grade BOPET for printing and lamination, specifically tailored for the TTR market.

While maintaining the core physical properties of polyester, our B-Grade series is optimized for high-volume production in the Barcode and Fax ribbon industries. This grade offers a balance between industrial-grade performance and economic efficiency.

Quality Profile: B-Grade vs. Standard

B-Grade film typically features the same thermal resistance as A-grade but may have minor variations that do not impact the final transfer quality in standard applications:

• Surface Consistency: Minor surface visual variations that do not affect ink adhesion or back-coating.
• Splice Count: May contain a slightly higher frequency of factory joins per jumbo roll (clearly marked for converters).
• Thickness Tolerance: Slight variations within the +/- 3-5% range, still suitable for most barcode and fax thermal heads.

Key Applications

1. Barcode Ribbons (Wax & Wax/Resin): The 4.5um B-grade is the industry standard for shipping labels and retail tags where high-speed throughput and cost-per-print are key.
2. Fax Thermal Ribbons: Excellent heat dissipation ensures the film does not stick to the thermal print head during long transmission cycles.
3. Lamination Base: Used as a thin carrier layer in multi-layer flexible packaging or protective laminates for paper-based tags.
4. Textile Transfer: Suitable for heat-press applications where graphics are transferred from the BOPET carrier onto fabrics.

Processing Benefits for Converters

• High Heat Resistance: Even in B-grade, the BOPET backbone prevents melting at standard thermal print temperatures (200degree
• + peaks).
• Dimensional Stability: Ensures that barcode "bars" and QR codes remain perfectly crisp and do not distort during the heat-transfer process.
• Slitting Compatibility: Designed to be slit into narrow widths (e.g., 55mm, 110mm) without edge fraying or cracking.

Note on Storage: To maintain B-grade integrity, rolls should be kept in their original polyethylene wrapping until use to prevent edge damage or dust accumulation, which can cause "pinholes" in the final ribbon coating.
