Seal Quality
Good seals are a result of time, temperature and pressure for the correct clean material. Several standard test methods are available to measure the strength of heat seals. In addition, package testing is used to determine the ability of completed packages to withstand specified pressure or vacuum. Several methods are available to determine the ability of a sealed package to retain its integrity, barrier characteristics, and sterility.
Heat sealing processes can be controlled by a variety of quality management systems such as HACCP, statistical process control, ISO 9000, etc. Verification and validation protocols are used to ensure that specifications are met and final materials/packages are suited for end-use.

Famous quotes containing the words seal and/or quality:
“The denial of our duty to act in this case is a denial of our right to act; and if we have no right to act, then may we well be termed “the white slaves of the North,” for like our brethren in bonds, we must seal our lips in silence and despair.”
—Angelina Grimké (1805–1879)
“The quality of mercy is not strained.
It droppeth as the gentle rain from heaven
Upon the place beneath. It is twice blest:
It blesseth him that gives, and him that takes.
‘Tis mightiest in the mightiest. It becomes
The thronèd monarch better than his crown.”
—William Shakespeare (1564–1616)
