THE ULTIMATE GUIDE TO STRETCH WRAP: FROM SELECTION TO APPLICATION The Importance of Stretch Wrap in Packaging Stretch wrap is a staple in the world of packaging for several reasons.
What is Stretch Wrap? Stretch wrap, also known as stretch film or pallet wrap, is a thin plastic film made from linear low-density polyethylene (LLDPE).
Different Types of Stretch Wrap Stretch wrap can be categorized into two main types: hand (manual) stretch wrap and machine stretch wrap.
Cast stretch wrap:
Made by feeding plastic pellets into a heated die, this type of stretch wrap has a glossy and clear appearance. It offers excellent puncture resistance, making it suitable for packaging sharp or pointed objects.
Blown stretch wrap:
Blown stretch wrap is produced by melting plastic resin through an extruder and then blowing it through a circular die, creating a thicker and stronger film. Blown stretch wrap is ideal for heavy and irregularly shaped items.
