Printing Grade BOPET Film With Heatsealable--for High-performance Printing And Subsequent Packaging

Printing Grade BOPET (Biaxially Oriented Polyethylene Terephthalate) Film with a Heatsealable Coating is a specialized, multi-functional polyester film engineered for high-performance printing and subsequent packaging. It combines the inherent advantages of a standard printing-grade BOPET film—such as excellent dimensional stability and superior printability—with a thermally activated sealant layer applied on one or both sides. This unique structure allows the film to serve as both the primary printed substrate and the sealing layer in flexible packaging structures, streamlining production and enabling innovative designs.

• Exceptional Printability: The treated surface provides high dyne levels (typically >44 dynes/cm) for outstanding adhesion of flexographic, gravure, and digital inks, ensuring vibrant, scratch-resistant graphics.
• Reliable Heat Seal Performance: The co-extruded or coated sealant layer (often a copolymer like PET-G, APET, or a proprietary blend) allows for strong, consistent seals to itself (fin-seal) or to other substrates (lap-seal) at controlled temperatures (typically ranging from 110°C to 150°C).
• High Barrier Properties: Offers excellent resistance to moisture and gases, extending product shelf life. This can be further enhanced with metallization or oxide coatings.
• Mechanical Strength & Durability: Possesses high tensile strength, puncture resistance, and stiffness for reliable machinability on high-speed filling and packaging lines.
• Clarity & Gloss: Provides a brilliant, optically clear base that enhances printed image quality and product presentation on shelf.

To ensure the longevity and performance of our BOPET film, please adhere to the following guidelines:

• Shelf Life: 12 months from the date of manufacture.
• Storage Conditions: Store in a cool, dry place away from direct sunlight and moisture.
• Temperature Range: 10°C - 30°C.
• Humidity: Keep below 60% relative humidity.
• Handling: Avoid folding or creasing the film to prevent damage.
