PUDI Food-Grade Printed Sealing Film

1. Product Name

2. Key Product Highlights (Bullet Points)

• Versatile Sealing Performance: Engineered to create a hermetic seal on a wide variety of tray materials, including Polypropylene (PP), Polystyrene (PS), Polyethylene (PE), and APET, ensuring leak-proof containment.
• Consumer Convenience (Easy-Peel): Available in "Easy-Peel" formulations that allow consumers to remove the lid cleanly without tools or excessive force, while maintaining a strong seal during transport.
• Tamper-Evident Security: Provides a visible, tamper-evident seal that guarantees product safety and integrity, a critical requirement for retail food packaging and pharmaceutical applications.
• Extended Shelf Life: Multi-layer structures (incorporating EVOH or PVDC) provide high barriers against oxygen and moisture, significantly extending the "use-by" date of fresh and processed foods.
• Optimized for Automation: Designed for high-speed heat-sealing machines (rotary or flatbed), offering consistent sealing temperatures and clean cutting properties to minimize production downtime.

3. Technical Specifications Table

• Leak-Proof Integrity: The advanced sealant layer bonds securely to the tray rim, preventing leaks of oils, sauces, or juices during rough handling and logistics.
• Shelf Appeal & Printability: The film surface is treated for high-quality flexographic or rotogravure printing, allowing you to showcase your brand logo, nutritional info, and barcodes with vibrant clarity.
• MAP Compatible: For fresh meats and salads, our high-barrier films are essential for Modified Atmosphere Packaging (MAP), retaining the gas mixture inside the tray to keep products looking fresh.
• Machine Efficiency: The film is slit and wound to precise tolerances, ensuring smooth feeding through automated sealing machines without wrinkling or misalignment.
• Safety First: Manufactured in compliance with FDA and EU regulations, ensuring no harmful substances migrate into the food product.

• Seal Strength: Adjustable based on polymer blend (ranging from 1.5 N/15mm for easy peel to > 5.0 N/15mm for permanent).
• Puncture Resistance: High resistance to tearing during the sealing and ejection process.
• Optical Properties: High gloss finish for premium product visibility.

5. Application Scenarios

• Fresh Meat & Poultry: High-barrier lidding for trays of beef, chicken, and pork (MAP packaging) to maintain color and freshness.
• Dairy Products: Permanent sealing for yogurt cups, cream cheese, and butter tubs to prevent contamination and leakage.
• Ready Meals & Catering: Easy-peel films for microwaveable trays (CPET/APET) allowing convenient access for consumers.
• Fresh Produce: Breathable or barrier lidding for cut fruits, salads, and vegetables to manage respiration.
• Pharmaceuticals: Blister packs and medical trays requiring sterile, tamper-evident seals.

6. Selection Guide: Choosing the Right Seal

• Seal Strength (Peelability):
  • Easy Peel: Best for consumer-facing retail packs (yogurt, deli salads) where convenience is key. The film peels back in one piece without leaving residue.
  • Permanent Seal: Best for industrial transport or products with heavy oils/sauces where leakage is a risk. The film may tear upon removal.
• Tray Compatibility:
  • It is critical to match the film’s sealant layer to the tray material.
  • PP Film seals best to PP Trays.
  • PE Film seals best to PE/PS Trays.
  • Note: Using the wrong film can result in weak seals or "cold seals" that pop open.
• Barrier Requirements:
  • Standard: For dry goods or short shelf-life items (bakery, bread).
  • High Barrier: For red meat or fish requiring long shelf life and oxygen protection.
