Cold laminating machines offer certain distinct advantages compared to hot laminating machines:
Because cold laminators do not use heat, no electricity* is needed to operate the machine. That means there is no warm-up time and your material will move quickly through the laminator. There is no need to adjust the roller tension or thermostat. All you have to do is turn the handle! Also, little maintenance is required compared to hot roll laminators.
*Some cold laminating machines, such as the Brother Cool Laminator, provide automatic feed and trimming, and require electricity.
With cold lamination, wrinkles or bubbles are much less likely to form.
Cold laminators won't harm heat sensitive documents or photographs.
The plastic laminate won't melt and stick to the rolls as it can with a hot laminator, meaning you won't experience a burnt plastic odor. And no heat means no chance of burns and no potential fire hazard -- all reasons why cold laminators are a practical choice for schools, offices, and sensitive work environments. They are ideal with untrained or unsupervised staff who have a need to use the machine.
Other than small pouch laminators, hot laminating machines require a trained operator. With cold lamination on the other hand, most machines can be run by anyone.
