SEAL INITIATION TEMPERATURE
Measure of lowest temperature at which the required hot tack and seal strength levels are both achieved. Seal range is the temperature range over which hot tack and seal strength are greater than the acceptable minimum required levels. Maximum hot tack level indicates what maximum loading the sealing material can sustain during the packaging cycle.
SECANT MODULUS
Measure of stiffness. Higher the number, the stiffer the film. ASTM D 882
SINGLE WOUND SHEETING
Slip
Slip is added to polyethylene resin to make it slipperier as the name implies. Slip agent, most commonly an erucamide or oleamide, exhibits a "blooming" phenomenon. Slip exudes to the surface of the polyethylene film to create a lubricated effect on the finish, or coefficient of friction (COF). A common example of a very high slip film is a bread bag. The same parts per million of slip produces a higher slip / lower COF film as gauge is increased. This is explained by what is known as the reservoir effect. The same parts per million exuding to the surface area of a thicker film has a larger reservoir of slip which all wants to get to the surface. Two applications which should never have slip are medical applications involving gamma irradiation sterilization and tamper evident bags with a tape closure.
