Why Water Resistance is a Critical Feature That Cannot Be Ignored in the Packaging Industry?
As a senior operator in the packaging industry, I understand the importance of waterproof protection in logistics and transportation. Transparent stretch film, as a core material in modern packaging, has waterproof performance that directly affects product integrity and customer satisfaction. Products in the U.S. market need to withstand complex and variable transportation environments, from humid maritime shipping to rainy land transportation. Waterproof performance has become a key indicator for measuring the reliability of packaging materials. This article will provide an in-depth analysis of the waterproof characteristics of transparent stretch film to help you make smarter packaging choices.
Analysis of Waterproof Performance Grades of Transparent Stretch Film
Different materials of stretch film have varying waterproof grades. Below is a comparison of the waterproof performance of mainstream transparent stretch films:
| Material Type | Waterproof Grade | Suitable Environment | Cost Index |
|---|---|---|---|
| PE Standard Film | Medium Waterproof | Indoor storage, short-distance transport | ★★☆☆☆ |
| PVC Reinforced Film | Medium-High Waterproof | Regular logistics, rainy areas | ★★★☆☆ |
| LLDPE High-Performance Film | High Waterproof | Cross-border transport, high humidity environments | ★★★★☆ |
| Nano-Coated Film | Super Waterproof | Maritime shipping, extreme climates | ★★★★★ |
Technical Principles Behind Waterproof Performance
Molecular Structure Density
High-performance stretch film uses linear low-density polyethylene (LLDPE) material, which has a tighter molecular structure that effectively blocks water penetration. Laboratory tests show that the waterproof performance of LLDPE film is 47% higher than that of standard PE film.
Advanced nano-coating technology creates a microscopic protective layer on the film surface, causing water droplets to form a rolling ball effect, significantly enhancing waterproof performance. This technology allows the stretch film to remain waterproof for 24 hours even in heavy rain environments.
