Biaxially Oriented Polyamide (BOPA) film is a high-performance packaging material with excellent mechanical strength and gas barrier properties. This versatile film offers superior puncture resistance (>200 g/μm) and tear resistance, making it ideal for packaging applications requiring high protection.
Our BOPA Nylon film features exceptional gas barrier properties (oxygen transmission rate <30 cm³/m²·24h·atm), effectively extending the shelf life of food products. With thickness ranging from 15-25μm and width up to 8.2 meters, it provides extensive versatility for various packaging applications.
With excellent transparency (>90%) and good printability, our BOPA Nylon film offers outstanding solutions for product appearance and brand presentation. The film also features excellent heat resistance (withstanding temperatures up to 220°C), suitable for various thermal processing applications.
Our BOPA Nylon film is manufactured in advanced production facilities, meeting stringent quality standards to provide consistent performance for demanding packaging applications.

Processing Information
Printing
BOPA Nylon film is compatible with various printing methods, including flexography, gravure, and offset printing. The surface is corona-treated to provide excellent ink adhesion.
Lamination
Can be laminated with various substrates using solvent-based, solventless, or water-based adhesives. Commonly used as a middle barrier layer in multi-layer laminated structures.
Heat Sealing Properties
BOPA itself does not have heat sealing properties; it typically needs to be laminated with heat sealable materials to achieve package sealing performance.
Storage and Handling
Store in a cool, dry place away from direct sunlight. Recommended conditions: temperature 15-25°C, relative humidity 45-65%. Shelf life is 12 months when properly stored.
BOPA Nylon Film Applications
Our BOPA Nylon film is widely used in various packaging applications requiring high barrier properties, mechanical strength, and transparency:
Vacuum Packaging
Due to its excellent gas barrier and mechanical properties, it is ideal for vacuum packaging of meat, seafood, and cheese products requiring extended shelf life.
Retort Packaging
Superior heat resistance and mechanical strength make it an ideal choice for retort packaging and high-temperature sterilization packaging.
Laminated Packaging
Serves as a barrier layer in multi-layer structures, providing excellent protection for food, pharmaceutical, and cosmetic products.
Oil and Fat Packaging
Excellent oil resistance makes it an ideal choice for packaging oils, condiments, and oily food products.
Frozen Food
Maintains mechanical properties in low-temperature environments, suitable for frozen food and refrigerated storage applications.
Pharmaceutical Packaging
High barrier properties and cleanliness make it suitable for packaging pharmaceutical products and medical devices.
