About thermal Binding Covers
Thermal soft covers are used for perfect binding, a popular binding style that uses heat-activated adhesives to create an attractive, uncluttered bind. Perfect binding is commonly used on both soft cover and hardcover books, as well as magazines, because it allows for easy stacking and storage (unlike other binding styles which tend to have a bulkier finish). Since the documents are secured with glue, no punching is required to achieve a secure bind.
Like traditional binding covers, thermal soft covers are made from paper or clear plastic (or a combination thereof) and are available in a variety of finishes. Instead of having separate front and back covers, thermal soft covers come as a pre-scored, solid piece (similar to a file folder) that has a strip of thermally-activated adhesive down the center. To create a bind, simply place your document within the cover and insert the cover into your thermal binding machine (following the manufacturer’s instructions). Because the covers are made as single pieces, they are available in different spine sizes that are specifically designed to accommodate the thickness of your report. They are offered with spines as small as 1/16" (capable of holding 1-10 pages of standard 20 lb. paper) and 1-3/4" (capable of holding 280-350 pages of standard 20 lb. paper).
