- Mechanical Damage Resistance: Forms a tight, secure wrap that protects against impacts, dents, and other physical damage during handling and transportation.
- Load Stability: Compresses and stabilizes the coil, preventing shifting or unwinding during transit.
- Tear and Puncture Resistance: Durable stretch film resists tears and punctures, maintaining the integrity of the protective barrier.
- UV Protection (Optional): Some stretch films are UV-stabilized to protect coils stored outdoors from sun damage.

The combination of these two layers in TEW creates a robust protective shield for steel coils, ensuring they arrive at their destination in optimal condition.

Material Selection for Optimal Moisture Barrier

Choosing the right wrapping materials is not just about cost; it's about ensuring effective protection against corrosion, particularly from moisture, which is a major threat to steel coils. Key considerations for material selection include:

Moisture Vapor Transmission Rate (MVTR): Select materials with a low MVTR to minimize moisture permeation. Polyethylene and specialized barrier films are excellent choices for their low MVTR values.
Water Resistance: Ensure the material is inherently water-resistant, preventing water absorption and direct contact with the steel coil.
Chemical Inertness: The material should not react chemically with steel or any coatings on the coil surface to avoid corrosion or discoloration.
Durability and Strength: Materials must be strong enough to withstand handling, transportation, and storage conditions without tearing or losing their protective properties. Consider factors like tensile strength, tear resistance, and puncture resistance.
Temperature Resistance: Choose materials that can withstand the expected temperature range during storage and transit without degradation.
Cost-Effectiveness: Balance material performance with cost to find the most economical solution that meets protection requirements.

Commonly used materials and their properties are summarized below:

Material	Moisture Barrier Properties	Mechanical Protection	Cost	Notes
Polyethylene Cloth	Excellent	Good	Moderate	Primary moisture barrier, good cushioning
Stretch Film (Standard)	Good	Moderate	Low	Cost-effective for general protection, load stabilization
Stretch Film (Barrier)	Excellent	Moderate	Moderate to High	Enhanced moisture barrier, better for long-term storage or humid conditions
复合纸 (Laminated Paper)	Moderate to Good	Good	Moderate	Paper laminated with PE or aluminum for improved barrier properties
VCI Films/Papers	Excellent	Good to Moderate	High	Vapor Corrosion Inhibitors release chemicals to prevent rust formation
