PUDI Breathable Stretch Film

1. Product Name

2. Key Product Highlights (Bullet Points)

• Controlled Respiration: Engineered with specific permeability rates to allow Oxygen ( $O_2$ ) and Carbon Dioxide ( $C{O}_2$ ) exchange, allowing fresh produce to "breathe" and preventing anaerobic fermentation.
• Condensation Control: The breathable structure minimizes water vapor buildup inside the package, preventing "fogging" and liquid accumulation that leads to mold and rot.
• High Clarity & Gloss: Despite being breathable, the film maintains excellent transparency, ensuring your fresh products look vibrant and appetizing on retail shelves.
• Superior Puncture Resistance: Made from high-grade Polyethylene (PE) blends, offering strong protection against sharp vegetable stems and rough handling during transport.
• Machine & Hand Compatible: Available in formulations suitable for both automated rotary wrappers and manual pallet wrapping, offering flexibility for your packing line.

4. Detailed Product Description

• Reduced Spoilage: By preventing the buildup of ethylene gas and excess moisture, the film drastically reduces the risk of bacterial growth and rotting during long-haul transport.
• Visual Appeal: The anti-fog properties ensure the film remains clear, so distributors and retailers can easily inspect the quality of the produce without removing the wrap.
• Load Stability: While it allows air to pass, the film still provides excellent tensile strength and cling, keeping the pallet unitized and secure against shifting.
• Versatility: Suitable for a wide range of crops, from leafy greens that require high oxygen to root vegetables that need moisture control.
• Cost-Effective: Reduces financial losses associated with spoiled goods. One pallet of spoiled produce costs far more than the price difference of the film.

• Gas Permeability: Optimized $O_2$ and $C{O}_2$ transmission rates to match the respiration curve of fresh produce.
• Puncture Resistance: High resistance to piercing by sharp stems (e.g., asparagus, broccoli).
• Elongation: > 300% (excellent for pre-stretch machines).

5. Application Scenarios

• Fresh Produce Pallets: The primary application. Wrapping pallets of bagged potatoes, onions, carrots, and apples for storage and transport.
• Leafy Greens & Brassicas: Ideal for broccoli, cauliflower, and lettuce, which have high respiration rates and are prone to "sweating" and yellowing.
• Beverage Pallets: Sometimes used for glass bottles to allow airflow and prevent condensation buildup that can damage cardboard trays.
• Floral Transport: Protecting bouquets and potted plants during shipping while allowing them to breathe.
• Cold Storage: Essential for goods stored in refrigerated warehouses where temperature fluctuations can cause condensation on non-breathable films.

6. Selection Guide: Choosing the Right Breathability

• Respiration Rate:
  • Low Respiration (Root Vegetables): Standard breathable film is usually sufficient to prevent sweating.
  • High Respiration (Leafy Greens/Berries): High-Flow breathable film is recommended to ensure enough oxygen reaches the product to prevent suffocation.
• Environment:
  • Refrigerated Transport: Breathable film is critical here to prevent fogging caused by the temperature difference between the cold air and the product.
  • Ambient Transport: Breathability helps prevent heat buildup inside the pallet.
• Machine Settings: Breathable film may require slightly different brake tension settings than standard barrier film. We recommend testing on a few pallets before full-scale rollout.
