Biaxially Oriented Polypropylene (BOPP) foil is a versatile, high-performance packaging material made by stretching polypropylene film in both the machine direction (MD) and across the machine direction (TD). This biaxial orientation enhances the film's strength, clarity, barrier properties, and resistance to impact and puncture, making it ideal for a wide range of packaging applications.
Key Properties of BOPP Foil
- High Tensile Strength: The biaxial orientation process increases the tensile strength of the film, making it strong and durable.
- Clarity and Gloss: BOPP films are highly transparent with a glossy finish, which is beneficial for packaging that requires product visibility.
- Barrier Properties: BOPP provides an effective barrier against moisture, oxygen, and other gases, extending the shelf life of packaged products.
- Heat Sealability: BOPP films can be heat-sealed, which is crucial for creating secure and airtight packaging.
- Printability: The surface of BOPP film is suitable for high-quality printing, making it ideal for packaging that requires branding and product information.
Common Applications of BOPP Foil
- Food packaging (snacks, candies, fresh produce)
- Labels and tapes
- Pharmaceutical packaging
- Lamination
