Stretch Film: Types, Specifications and Applications

How hand, machine and pre-stretched films differ and which specifications matter.

Stretch Film: Types, Specifications and Applications

Types of stretch film

  • Hand stretch film is applied manually, usually from a hand dispenser. It suits low volumes.
  • Machine stretch film is supplied on larger rolls for pallet wrapping machines.
  • Pre-stretched film is stretched during manufacture, so it is thinner and easier to apply by hand.
  • Mini stretch film is a narrow roll for bundling small items.

Specifications to confirm

  • Thickness (microns)
  • Roll width and length
  • Core size and roll weight
  • Cast or blown manufacture
  • Clear or coloured film

Selecting the right film

Heavier and sharper-edged loads usually need thicker or higher-performance film. Wrapping method matters too: machine films are designed to be stretched by the machine and may perform poorly by hand. Always test on your actual load before switching film.
