Agricultural Stretch Films — Silage & Bale Wrap by DERFLEX
DERFLEX agricultural stretch films are engineered for modern farming: multi-layer co-extruded silage and bale wrap films with excellent puncture resistance, airtight sealing and long-term UV protection. Our factory-direct production ensures consistent quality, competitive pricing and flexible customization for global customers.

Product Overview
DERFLEX Agricultural Stretch Films are manufactured using advanced multi‑layer co-extrusion technology. Each layer is optimized — inner cling layer for excellent adhesion, middle layers for mechanical strength and puncture resistance, and outer UV-protective layer to resist photodegradation. These films are designed for:
- Silage & round bale wrapping (hay, straw, corn stalks)
- High-performance bale wrap for long-term outdoor storage
- Mulching and temporary ground cover
- Protection and sealing for greenhouse installations
Available in standard widths (500mm, 750mm, 1250mm) and roll lengths (150m–750m), colors (black, green, white, clear) and in bespoke constructions on demand. We provide both manual and machine-grade films for contractors and farms of all sizes.

Key Features & Benefits
- Airtight Sealing — Excellent cling ensures anaerobic conditions essential for high-quality silage fermentation.
- High Puncture & Tear Resistance — Multi-layer construction resists tearing from bale edges, twine and foreign objects.
- UV Protection — Outer layers contain stabilizers to extend outdoor lifetime.
- Consistent Film Gauge — Factory-controlled extrusion for uniform thickness and reduced waste.
- Machine & Manual Compatibility — Options for machine-grade film with tight tolerances and manual wrap films with superior cling.
- Recyclability — Where local facilities permit, films are recyclable (separated by polymer type). We offer guidance for end-of-life handling.
Applications
DERFLEX Agricultural Stretch Films are engineered for diverse agricultural scenarios:
- Silage Wrapping — Create airtight bales for high-nutrition forage preservation during long storage.
- Bale Wrapping — Protect round and square bales from moisture, weather and UV damage.
- Mulch & Ground Cover — Short-term soil protection and weed suppression.
- Greenhouse Films — Light-diffusing and UV-controlled films for protective structures (specialized constructions available).
- Feed & Bedding Storage — Airtight covers reduce mold risk in stored feed and bedding materials.
Case study excerpt: A dairy cooperative in northern Europe reduced silage losses by 18% after switching to DERFLEX 7-layer machine-grade film — improved puncture resistance and optimized UV package prevented spoilage during spring storage.
Quality Control & Certifications
DERFLEX manufactures within ISO 9001-controlled processes. We perform routine incoming material checks, in-line thickness monitoring, and mechanical testing of finished rolls. Third-party tests (SGS) for UV resistance, tensile strength and elongation are available on request for bulk orders.
- Factory: dedicated extrusion lines for agricultural films
- Quality checks: thickness gauge, tensile / elongation, puncture resistance
- Third-party testing and sampling available for large orders

Frequently Asked Questions
Q: What is the difference between machine-grade and manual stretch film?
A: Machine-grade film is designed for automatic wrappers with high-speed pre-stretching; it has tight gauge tolerances and controlled cling. Manual film has stronger cling and is thicker to withstand hand-wrapping irregular bales.
Q: How do I choose the right thickness?
A: Choose by application: standard silage wrapping often uses 25–35 µm layers with 3–7 co-extruded layers for balance between protection and cost. Heavier applications or rough bales may require thicker films or additional layers.
Q: Can you print my company logo on the film?
A: Yes. We offer customized printing for branding and handling instructions. Please note printed rolls may have minimum order quantities.
Customer Testimonials
