Salesman selling Shrinkwrapping Vs Overwrapping


Shrinkwrap

  • 3 sealing lines
  • Polyolefin or PVC Shrinkfilm.
  • 3 to 4 inches scrap. The film can be slightly bigger and it will shrink to the product dimensions.
  • Perforated Film – Less barrier property.
  • film has strong tensile strength, not easy to open.
  • Need shrink tunnel to shrink wrap the plastic. The product exposes the heat from the tunnel.
  • Can wrap any shape.
  • tall products tend to have dog ears.

Overwrap

  • Envelope Seals
  • BOPP film
  • No scrap. The film size must be exact.
  • The product must have 8 corners (Box form)
  • Need change over when the product size is different.
  • Overwrapping has barrier property –¬†cigarette and perfume products usually use it.
  • easy to open from the envelop seals.
  • No tunnel heating is required. Only short timing of contact heating to seal the Opp film.
