  1. Comprehensive Quality Control for Stretch Wrap Film Performance • Stretch Wrap Film  Key Performance Indicators • The remarkable physical and mechanical properties of stretch wrap film contribute to its widespread adoption across diverse industries.

  2. Key Performance Tests and Methods • Tensile  & Elongation at Break • Puncture Resistance • Water Vapor Transmission Rate (WVTR) Testing • Thickness Testing

  3. Auto Tensile Tester • 01 • 02 • Tensile  & Elongation at Break • Elastic Recovery, Deformation, and Tension Retention • Assess the film's capacity to return to its original state after being stretched, its susceptibility to permanent deformation, and its ability to maintain constant tension over time. • Measures the film's fundamental ability to withstand stretching forces and its elasticity before rupture.

  4. Auto Tensile Tester • 03 • 04 • Adhesion Testing • Puncture Resistance • Measures the stickiness between layers of the stretch film, which is fundamental to forming a secure, multi-layered wrap. • Test quantifies the film's resistance to piercing by sharp objects. 

  5. Thickness Testing • The thickness of stretch wrap films generally falls between 0.010 mm and 0.050 mm.  • Ensuring consistent film thickness is vital for maintaining uniform performance and material usage.   • Labthink C640 Thickness Tester is designed for accurate and repeatable measurements, offering user-friendly software and data management capabilities.

  6. Water Vapor Transmission Rate  • measures the amount of water vapor that passes through the film over a specific time under controlled temperature and humidity.  • It indicates the film's barrier properties against moisture, which is crucial for protecting humidity-sensitive goods, especially during long-distance or sea transport.

  7. Water Vapor Transmission Rate Test • C360 series • ASTM E96 • C360 series Water Vapor Transmission Rate Test Systems are based on the gravimetric principle • C306H • ASTM F1249 • C306H Water Vapor Transmission Rate Test System is based on infrared sensor method
