What makes a good Pressure Seal form?
Proper co-hesive chemistry and a proper method of applying the co-hesive to the form are paramount for achieving a secure seal. Pressure seal co-hesive is a volatile compound which requires active Quality measurement during the entire manufacturing process. Important as well is accurate perforation registration to ensure proper alignment of the perforations and co-hesive pattern during folding. Fold assist perforations that float in and out of registration will cause folding problems on a typical folder/sealer. In addition, this may cause the co-hesive pattern to align improperly when the form is folded. Floating registration of perforations will cause feeding problems on a folder/sealer and result in a poorly sealing form. Other factors that play an important part in a good quality pressure seal form are paper type, print quality, packaging and storage. It is important to select a forms manufacturer with knowledge of the critical factors involved in manufacturing pressure seal forms a
