Emerging Markets: Opportunities for Blown Film Applications Beyond Packaging

Blown film has long been used for packaging, from food wraps to carrier bags. But today, this technology is expanding into new industries. Modern machinery, better materials, and smarter controls are helping manufacturers make film for agriculture, construction, and even medical products.

This blog looks at how blown film applications are growing beyond packaging, and how producers can adapt their equipment to meet these new demands.

1. Agriculture: Strong and Sustainable Films

In farming, blown film is used for crop covers, mulch films, and greenhouse liners. These protect plants from pests, weather, and moisture loss.

New materials allow films to last longer and reduce waste. Some are made with UV protection, while others use biodegradable blends to cut plastic impact. Multi-layer extrusion lets you combine different materials, making films that balance strength, light control, and flexibility.

By adjusting machinery settings, producers can create films that help farmers save water and improve growing conditions. Learn more about efficient processes in How the Blown Film Process is Done Efficiently and Sustainably.

2. Medical and Healthcare Films

The medical sector needs clean, reliable materials. Blown film machines can now make medical-grade wraps, pouches, and barrier films for sterile products.

These films must be strong, smooth, and resistant to tearing. Web guiding and automatic controls help keep thickness even and reduce waste. Consistency is key in healthcare applications.

New polymer blends also make breathable films for dressings and gowns. This shows how flexible blown film technology has become. For more on precision control, see Why Blown Film Needs Precise Web Guiding.

3. Construction and Industrial Use

Construction projects rely on durable films for vapour barriers, floor protection, and weatherproof covers. These films must handle heavy loads, moisture, and sunlight.

Upgraded turning bar and idler systems make it easier to run thicker films without damage. These systems control tension, prevent creasing, and improve winding. They are especially useful for large-scale industrial production.

You can explore these solutions in our Turning Bar & Idler Systems page, which shows how better handling supports high-quality film production.

4. Supporting Sustainability

As industries move toward greener materials, blown film machinery must adapt. Lines that can run recycled or compostable resins give producers a clear advantage.

These materials behave differently from standard plastics, so control over heat and tension is vital. By upgrading controls, film producers can work with new resins while keeping performance high.

This flexibility helps businesses meet sustainability goals and respond faster to customer demand.
