- Anti-Rust Mechanism:
The reinforced aluminum-plastic composite VCI anti-rust, anti-static shielding, and moisture-proof aluminum foil packaging film/bag is developed based on VCI vapor corrosion inhibitor plastic film and anti-static shielding moisture-proof aluminum foil film. It integrates advanced VCI anti-rust technology, plastic extrusion blow molding technology, anti-static technology, and moisture-proof technology through a special composite processing method.
This product combines:
- Air, moisture vapor, corrosive gas, dust, and sunlight barrier properties required for vacuum drying packaging
- VCI anti-rust protection required for corrosion prevention packaging
- Anti-static shielding required for ESD-sensitive packaging
- Excellent physical strength required for packaging performance
It offers outstanding corrosion resistance, high strength, and anti-static shielding performance. It effectively protects mechanical parts, especially electronic products, from rust, moisture, and electrostatic damage.
It is especially suitable for:
- Integrated circuit boards
- Printed circuit boards (PCB)
- Communication equipment
- Electronic instruments and meters
- Machine tools
- Large military equipment
- Textile machinery
- Printing and packaging machinery
- Rubber and plastic processing equipment
- Compressors
- Engines
- Large electromechanical equipment and components
It is ideal for products and materials requiring both anti-rust, moisture-proof, and anti-static shielding protection during processing, storage, or sea transportation.
The material can also be converted into bags. Electronic products only need to be placed inside and sealed for protection.
- Application Fields:
■ Ferrous Metal Anti-Rust:
Suitable for all ferrous metal products such as cast iron, carbon steel, silicon steel, etc.
■ Multi-Metal Anti-Rust:
Suitable for alloy products composed of multiple metals such as steel, copper, aluminum, zinc, etc.
■ Copper-Specific Anti-Rust:
Suitable for copper and copper alloy products.
■ Precious Metal Anti-Rust:
Suitable for gold-plated and silver-plated precious metal products.
- Advantages / Features:
A. Excellent anti-rust performance with protection period up to more than one year. The protective vapor releases rapidly and can fully diffuse into every corner of the package within 2 hours.
B. Anti-rust particles can penetrate every corner inside the packaging, achieving effective rust prevention even in areas that other anti-rust products cannot protect.
C. Combines moisture barrier, corrosion gas barrier, dust protection, sunlight shielding, VCI anti-rust protection, anti-static shielding, and physical strength into one product. It solves multiple packaging problems simultaneously while remaining convenient, economical, and practical.
D. Excellent sealability, good toughness, transparent appearance, and allows direct observation of product condition.
E. Labor-saving, time-saving, cost-effective, environmentally friendly, and non-toxic.
F. Lightweight, soft, elastic, heat-insulating, thermal insulating, and moisture-proof.
G. Excellent vaporization performance. Direct contact with the workpiece is not necessary, and even if contact occurs, no crystallization will form on the product surface.
Suitable for anti-rust, anti-static shielding, and moisture-proof packaging of various metal materials and products during processing, storage, and sea transportation.
Overview of MIL-PRF-131K
MIL-PRF-131K is a military specification that covers the requirements for heat-sealable, greaseproof, flexible barrier materials with low water vapor transmission characteristics. These barrier materials are essential for military packaging, providing robust protection for a variety of applications. Whether wrapping electronic components, aerospace and military instruments, or machinery, MIL-PRF-131K ensures that the items are safeguarded against moisture and other environmental factors. The specification emphasises the use of laminated foil with polyethylene, ensuring a durable and heat-sealable barrier material that meets stringent military standards.
