Heat Seal Coating

Description

Adcote 49-126 is a proprietary code for Adcote 33R1MG.

Adcote 49-126 is a peelable heat seal coating designed for application to polyester, primed/unprimed foil, 

olefins, or paper for heat sealing to oriented polystyrene, high impact styrene, rigid polyvinyl chloride, or 

olefins.

Use

Adcote 49-126 is used as a peelable seal coating. Seals exhibit excellent hot tack for hot filled items such 

as jellies or jams or for medical applications. Initial sealing begins at approximately 200°F. Where 

aluminum foil is used as the lidding stock, the use of a vinyl wash coat prior to heat seal application is 

recommended. Application on unwashed foil is feasible, but peeling may then occur at the coating/foil 

interface.

Mixing Instructions

Heat with hot water or steam coil in the pan and a drum or pail heater on the container to 140°F. Reduce 

with thinner to 23% solids (approximately a 4:1 by volume reduction).

The gravure cylinder should also be preheated with warm solvent in the coating pan to prevent gelling of the 

coating in the gravure cells.

Pass through a heated tunnel to remove all solvents. Drying should be adjusted to give a web temperature 

(as measured with paper thermometers) of 175°F. This will insure good solvent releases essential to 

preclude blocking and to ensure satisfactory bond performance.

For optimum film continuity, web temperatures of 180-200°F should be achieved to reflow the film. 

Subsequent chilling should reduce rewind temperature below 100°F.
