Over the past few years, the use of PUR adhesive has become increasingly common in the industry. This is due to the fact that more adhesives provide PUR-binding capabilities, as well as improved bonding and bonding techniques, making PUR an economical solution for short-term projects. PUR's two traditional traps - cost and turnaround time - are largely alleviated.
We also note that PUR has more and more advantages in printers and designers. We have previously advised PUR to be used for the required projects, and customers are now designing products with PUR. To this end, there are several examples of projects that are well suited for PUR bindings: Almost by definition, the catalog has these three features: a large number of images, long shelf life and heavy usage patterns. While this may sound like a "triple blow" binding, but they are not PUR challenges.
The catalog usually has a full discharge image on each page; the amount of ink and coating in the trench requires the strength of the PUR, which still produces strong adhesion, although it is not directly bonded to the paper fiber. Likewise, the catalog is usually designed to cost a few months or more in the hands of the customer and must be constructed to withstand the use of such extensions. PUR adhesives are worth investing to ensure that your catalogs are kept together.
A combination of thicker coating materials with a minimum volume will often compromise user friendliness and exert excessive stress on the bonded edges. Traditional hot melt adhesives are often more rigid, reducing the flexibility of the book, resulting in improved failure rates. PUR adhesives do not have this problem because it is thin and creates a good link and keeps it flexible.
