Terms you may hear in a flexible packaging conversation.
You do not need to know these before contacting us. This reference is here when the language becomes useful.
COF+
Coefficient of friction. It influences how film slides over machine surfaces and against itself.
Hot tack+
The strength of a seal while it is still hot, before it has cooled to full strength.
OTR+
Oxygen transmission rate measures oxygen moving through a material under defined conditions.
MVTR+
Moisture vapor transmission rate measures water vapor moving through a material under defined conditions.
Seal initiation temperature+
The temperature at which a sealant begins to develop a useful bond under specified time and pressure.
Unwind direction+
The orientation in which printed roll stock feeds from the roll into packaging equipment.
Web width & repeat+
The roll width and the distance from one repeated printed design to the next in the machine direction.
Headspace+
The intentional space between the product fill and the package closure or top seal.
Forming web+
A bottom web designed to be heated and drawn into cavities before filling and sealing to a top web.
