Abstract (en)
[origin: US2009238502A1] A perforated large-size easy opening pouch is formed from a single sheet containing at least one layer of a film material, and the sheet forms a volume. The pouch also contains a seal containing a perforation. The perforation is completely surrounded by the seal. When a tear is initiated along the perforation, the tear propagates to a non-sealed portion of the pouch. A sealing jaw and a method for forming such a pouch is also described.
