Abstract
Au moins une surface d'un formulaire (2) pouvant être scellé par pression présente une ou plusieurs zones de scellement par pression, distribuées de façon que quand ledit formulaire est plié d'une manière prédéterminée, au moins deux régions recouvertes d'adhésif autocollant (17, 18, 19) entrent mutuellement en contact. Le pouvoir adhésif de l'adhésif utilisé pour fabriquer ces formulaires (2) est un facteur très important pour faciliter leur production, ainsi que pour mettre en évidence une éventuelle tentative d'ouverture non autorisée, par exemple par déchirure du substrat papier d'un formulaire scellé. De nombreux adhésifs étaient jusque-là considérés comme insatisfaisants, entre autres parce qu'ils donnaient une liaison adhésif-adhésif suffisamment faible pour permettre l'ouverture d'un formulaire non affaibli sans indication concomitante d'une tentative d'ouverture. L'affaiblissement local du formulaire (2) dans au moins une partie desdites régions permet d'utiliser une plus grande variété d'adhésifs, notamment au moins certains de ceux qui étaient rejetés. L'affaiblissement peut se faire par découpure/perforation partielle ou totale ; éraflure, grattage, rayure ou abrasion ; rainage ou gaufrage.
