L0001-PRO Lab Heat Sealer

Product details

An economic Laboratory Heat Sealer to help determine the sealing parameters of film, l

aminated films, coated paper and other flexible barrier materials. The IDM lab Heat Sealer 

is used to measure the heatsealability of the web surface or sealant layer of materials.

Short dwell time web sealability can also be performed on the LHS.  This is a test seal that 

is made at a dwell time shorter than required for the sealing surface to reach the jaw 

temperature level, simulating conditions on high-speed vertical form-fill machines or slower 

machines where the condition of non-equilibrium also exists. Criteria of judging heatsealability 

is the strength of the actual heat seal.  Parameters include heat seal temperature, dwell 

time and the pressure of the heat seal for materials that have different melting points,

Sealing is initiated by a foot switch, a pneumatic cylinder is used to lower the Upper Sealing 

Bar to seal.  The timer is then used to determine the length of time the Sealing Bars will be 

in contact with the sample at the set sealing pressure.  Producing repeatable and reliable test 

samples.
