Proper storage of plastic strapping: why it matters

Plastic strapping is designed to deliver reliable performance in demanding transport and logistics applications. To ensure that performance remains consistent throughout the product's lifecycle, proper storage and handling are essential.

Especially during the summer months, high temperatures and direct sunlight can affect plastic materials. Extended exposure to heat may lead to changes in the strapping, including a natural shrinkage effect on the outer layers of the coil. In addition, excessive UV exposure may influence the physical properties of the material over time.

Storage pictogram for plastic strapping: A strapping coil is shown inside a protected storage building. Above the building, the graphic displays the sun, clouds, and precipitation. Inside the building, a thermometer symbol indicates “max. 50°C / 122°F”. The image illustrates that strapping should be stored in a dry, weather-protected area, away from direct sunlight, at a maximum storage temperature of 50°C (122°F).

Recommended storage conditions

  • To maintain optimum product quality and performance, we recommend:

  • Storing strapping in a dry, covered area away from direct sunlight.

  • Avoiding prolonged exposure to high temperatures. The recommended maximum storage temperature is 50°C (122°F).

  • Protecting products stored outdoors with suitable pallet covers or protective sheeting whenever outdoor storage cannot be avoided

  • Inspecting deliveries upon receipt and reporting any irregularities immediately.

Understanding sun shrinkage

When plastic strapping is exposed to direct sunlight for extended periods, the outer layers of the coil may heat up more intensely than the inner layers. As temperatures fluctuate, this can create tension within the coil and cause localized deformation or "sun shrinkage."

While this phenomenon is primarily related to storage conditions, it can be minimized through proper handling and storage practices.

By following the recommended storage guidelines, users can help ensure that plastic strapping retains its intended performance and reliability, even under challenging summer conditions.
