Cast polypropylene (CPP) is a widely used material in the food packaging sector. Thanks to its high transparency, heat resistance, and ease of processing, this type of film is ideal for packaging food products that require optimal presentation or post-packaging thermal treatments.
Essential Characteristics of Transparent and Glossy Film
To be suitable for food contact, cast polypropylene for food packaging must meet a series of technical and regulatory requirements. The main characteristics it must have include:
- High transparency: Ensures optimal visibility of the packaged product, making it more attractive to consumers.
- Heat resistance: Allows post-packaging thermal treatments, such as pasteurization or sterilization, without compromising the film’s integrity.
- Controlled slip properties: Enables effective handling on high-speed packaging machines, preventing jams or sliding issues.
- Excellent sealability: Ensures airtight closure of the package, preserving food freshness and safety.
- Regulatory compliance: Must be certified for direct food contact in accordance with European Regulation EU 10/2011.
What Are the Benefits of Using Polypropylene in Food Packaging?
Using cast polypropylene for food packaging offers numerous advantages:
- Better food preservation, thanks to its protective barrier against moisture and external agents.
- Adaptability to various packaging technologies, including flow-pack, thermoforming, and heat sealing.
- Eco-friendly solution, as CPP is recyclable and can be produced with biodegradable or environmentally friendly materials.
Thanks to its properties, cast polypropylene is widely used for:
- Packaging of snacks and baked goods
- Wrapping for dairy products and cheeses
- Vacuum and modified atmosphere packaging (MAP) films
- Sealing films for food trays
Cast polypropylene represents a versatile and safe solution for food packaging, ensuring transparency, heat resistance, and compliance with safety regulations. Its ability to adapt to modern packaging systems makes it a strategic choice for food industry companies looking to enhance both the preservation and visual appeal of their products.
