GBC - Laminating Hints and Tips

For those looking to purchase, but are undecided on the model, our How to Choose the Right Laminator post provides a wealth of information on choosing the machine suited to your needs. Or, if you already own a laminator, follow these simple tips to resolve issues and make the most this amazing machine.

Laminating shapes and sizes

When laminating irregular shapes: 

  • Make sure that the sealed edge of the laminate enters the machine first
  • Ensure content is as close as possible to that sealed edge. 
  • If laminating multiple irregular shapes, place them all as close together as possible near the sealed edge.


Always laminate closed end first

Feeding work in ‘open end’ first is the number one cause of laminating jams. Always ensure that the closed side enters the machine first to significantly reduce hold ups.

Laminating maintenance

Run a cardboard laminator cleaning sheet (without laminating pouch) through your machine regularly. This helps to remove adhesive blockages which can appear over time and may contribute to jams.

Don’t laminate an empty pouch

Never laminate a pouch without content as it may result in malfunction or jamming. 

My laminate is not clear, what’s gone wrong?

Cloudy laminates usually mean that the heat was not appropriate. Adjust your heat settings and continue.

There are waves and bubbles in my laminate. Why is this?

This is the opposite of a cloudy lamination and the heat is too high. Adjust your settings and wait for several minutes before continuing. 

Test settings first

If unsure of your settings, run a test sheet before laminating your documents to eliminate any issues and get it right first time.

Cut laminate after completion

If you cut pouches before lamination, your misshapen pouch may interfere with the rollers. Heat-sealing your work means that it is protected all around and is safe to be trimmed to the required size after the job is done.

Be aware of content

While laminators are the perfect way to preserve work, be aware that some printed documents can be heat sensitive and may not react well with a laminator. This can apply to certain types of fax paper or printed tickets. If in doubt test a similar quality paper before laminating something valuable.



Mix up your microns

Pouches (measured in microns) vary in thickness from 75 to 250mm. Different thicknesses give different textures and strengths, and what may be right for one have job may not be ideal for the next. Experiment with your laminator and micron thickness to get the perfect blend for the task in hand.
