PE Shrinking Film: A Technical Marvel in Modern Packaging
PE Shrinking Film represents the pinnacle of packaging technology, engineered through advanced polymer science to meet stringent industrial and commercial demands. This high-performance material combines exceptional strength, flexibility, and environmental consciousness.
Material Composition and Production Process
Composed primarily of polyethylene (PE), this film undergoes precise extrusion and orientation techniques to achieve optimal shrink characteristics. The molecular structure ensures uniform shrinkage at temperatures between 50°C and 150°C, depending on formulation.
Key Technical Specifications
- Shrinkage Rate: Up to 70% in both machine and cross directions
- Tensile Strength: Exceeds 50 MPa in both directions
- Elongation at Break: Maintains over 300% elongation
- Puncture Resistance: Excellent resistance to tears and punctures
- Barrier Properties: Protection against moisture, oxygen, and UV light
- Temperature Range: Operational from -40°C to +80°C
Core Technical Advantages
Precision Shrinkage: Controlled and predictable shrinkage ensures tight, secure wrapping around products of various shapes and sizes.
Enhanced Mechanical Properties: Exceptional strength-to-weight ratio with high tensile strength and puncture resistance.
Superior Clarity and Aesthetics: Excellent optical clarity maintains product visibility while protecting against dust and scratches.
Environmental Compatibility: Recyclable material with production processes that minimize energy consumption and carbon footprint.
