Abstract: A flexible bag comprises flexible sheet material assembled to form a semi-enclosed container having an opening. The bag has a drawtape closure for sealing the opening. The sheet material of the drawtape closure exhibits elastic-like behavior along at least one axis. The sheet material of the drawtape closure comprises a first region and a second region. The first region and said second region are comprised of the same material composition and each has an untensioned projected pathlength. The first region undergoes a substantially molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the sheet material is subjected to an applied elongation in a direction substantially parallel to an axis in response to an externally-applied force upon the sheet material of the drawtape closure.
Abstract: Disclosed is a novel polypeptide having an amino acid sequence substantially as shown in SEQ ID NO:2, or substantially similar to the amino acid sequence encoded by the DNA insert contained in ATCC Deposit No. PTA-4086. Also disclosed is an isolated polynucleotide substantially as shown in SEQ ID NO:1, or substantially similar to a nucleotide sequence contained in a plasmid having all of the identifying characteristics of ATCC Deposit No PTA-4086, encoding the polypeptide. Further disclosed is an expression system comprising the above polynucleotide.
