Heat sealers on stretch wrappers grinds my gears!

Shouldn’t you handle the film correctly and NOT put that bandage on the open wound?

Wait, how can that be?  Doesn’t Highlight Industries make heat sealers? The answer is: rarely.

Let’s pull back the curtain and show why they are not always needed with Highlight Industries machinery. 

Heat sealers are to seal the film to itself after the pallet has been wrapped.  Sounds simple enough right?  The rub for most is the two primary types of systems out there.  The first is a heated roller that rolls down the side of a pallet (on an automatic conveyor) and melts the film layers together.  The second is a heated tamp pad (typically mounted in the same position).

The problem:

  • Heated Roller : These in theory are great but the combination of heat and the roller make it hard to properly regulate the heat and hold the narrow band between not hot enough and too hot.  Additionally the roller is a high wear item so these have proven to be unreliable and a maintenance headache.
  • Heated Tamp : Although more stationary and fewer moving parts the problem is in transferring a pallet into the area and stopping it in order to heat your seal band.  Costly in throughput and almost equally as unreliable.

The Solution:

Highlight typically will offer you the following deal: if you try our system and feel as though you still need a heat sealer, we will provide it.  In years of building machines, we have built very few!   Go ahead and ask, WHY?

We incorporate Dual Powered Hydro Stretch (DPHS) systems into some of our machinery as our film stretch method (we’ll explain more on this below).  By stretching film at 200%, others will take the tacky film and stretch every 10” into 30” taking all of the tackiness of the film and spreading it out, making it ineffective of holding the film together and creating a film tail (which will impact any automatic handling devices in your production).

Highlight Industries DPHS will have complete control over the film and stretch percentage.  It is really quite simple…reducing or eliminating the stretch at the end of the pallet wrap process (for only a couple of feet of film) will not only reduce the amount of film breaks (we will expand on this in another blog) But it will also keep all of your tackiness together.  The end result is film tails that stay in place. 

Combine that with the wiping process as the pallet exits and you are set for the life of the pallet.  Now you are putting the film to work the way it was intended to be used when you bought it.
