HEAT SEALING 7-MIL MYLAR BAGS

We are often asked "What do I use to heat seal mylar bags?"  or "Will my food saver vacuum sealer work on your bags?"  

 

A hair straightening flat iron is one of the simplest and most reliable ways to seal our bags.  The best seal is achieved at a temperature setting of 375-425 deg. F which is the temperature of most hair straightening flat irons making them the ideal solution for heat sealing laminated foil barrier bags.   

 

 

FOODSAVER and other vacuum packing systems:

The FoodSaver system will not work with our bags because of the thickness (7-mil on each side = 14 mil total sealing thickness).  Some of the higher end $$$ vacuum packing / sealing systems do work on 7 mil bags.  However, there are so many different systems available with different settings / parameters that we do not make specific recommendations without having tested those systems.   

 

IMPULSE SEALERS:

Impulse sealers will work but require a bit of experimentation to find a setting that provides an even seal without burning entirely through the bag.  The width of the seal is narrow ~5mm
