Metallizing Base BOPP Film --heat Sealable Film Applied To Food Package

Metallizing base BOPP film is a specially engineered biaxially oriented polypropylene (BOPP) film designed to serve as the optimal substrate for vacuum metallization. This process involves depositing a microscopic layer of aluminum (or other metals) onto the film's surface in a high-vacuum chamber. The primary purpose of this base film is to provide an exceptionally smooth, uniform, and receptive surface that allows for a brilliant, high-gloss metallic finish after coating. It acts as the critical foundation that determines the quality, performance, and efficiency of the final metallized product.

1. Excellent Surface Smoothness: A nano-scale smooth surface is crucial to achieve a mirror-like, high-gloss, and pinhole-free metallic layer without defects.

2. Low Heat Shrinkage: Exhibits outstanding dimensional stability under the heat of the metallization process, preventing wrinkles or distortion.

3. High Barrier Foundation: While the metal layer provides the primary barrier, the BOPP base itself has good inherent moisture barrier properties, which are enhanced post-metallization.

4. Superior Mechanical Strength: Offers high tensile strength, stiffness, and puncture resistance, ensuring it runs flawlessly on high-speed metallizing and converting equipment.

5. Tailored Surface Treatment: Features controlled corona or plasma treatment on the metallizing side to ensure perfect adhesion (wet-out) of the aluminum layer, preventing delamination.

1. Optimal Metallizing Efficiency: Its specific design allows for higher machine speeds, lower aluminum consumption, and reduced waste during the vacuum deposition process, lowering overall production costs.

2. Enhanced End-Product Performance: The combination of a superior base film and a uniform metal layer results in a final product with:

   • Excellent Gas and Moisture Barrier: Extends shelf life of packaged contents.

   • Superior Light and UV Barrier: Protects light-sensitive products.

   • Brilliant and Consistent Aesthetics: Delivers a stable, luxurious metallic appearance.

3. Cost-Effectiveness: Provides the visual appeal and functional benefits of metal at a fraction of the weight, cost, and material usage compared to foil laminates. It also improves yield in downstream processes like printing and laminating.

4. Sustainability Benefits: Compared to aluminum foil laminates, metallized BOPP films use over 99% less metal, are lighter (reducing transportation emissions), and are often recyclable in polypropylene streams, supporting light-weighting and source reduction goals.

To ensure the longevity and performance of our BOPP film, please adhere to the following guidelines:

• Shelf Life: 6 months from the date of manufacture.
• Storage Conditions: Store in a cool, dry place away from direct sunlight and moisture.
• Temperature Range: 10°C - 30°C.
• Humidity: Keep below 60% relative humidity.
• Handling: Avoid folding or creasing the film to prevent damage.
