The only problem that I came across is the bags that are “specially made” for the food sealer cost a fortune! They aren't even made from recycled goods! I searched google to no avail on solving the problem, the closest I got was budget rolls $10 for a 8”x50' roll [33 square feet] and that is still outrageously high. I was perusing the plexiglass section when I saw painters plastic in 10'x50'x3.5mil rolls for $7 [500 square feet] so I picked up a roll [I splurged and got the recycled roll. The non recycled rolls are cheaper, but wheres the green in that?] .
I got home and made a bag using the sheeting and couldn't get it to vacuum. The problem was that the sheeting created its own seal too high up on the bag and wouldn't suck the air out of the lower part of the bag. A bit more googling and I found that the reason for this is that the “special” bags have air channels to allow the vacuum to suck all the air out.
I started trying to make my own vacuum bags by ironing the sheet over a window screen [didn't work] by using a tube to suck out the air and then sealing the corner [didn't work] and by attaching a straw to the bag and trying to seal it [didn't work] I was about to give up when I looked over at my hot glue gun and got the idea to make an air channel using hot glue.
The advantage of using hot glue is that it is non toxic, cheap [$3 for a 100 pack], and hot melt! I made a channel, made a bag, and tried it out. Shazam! It worked wonderfully! It worked so well that I decided to make an ible out of it!
Before I knew it I was vacuuming everything I could, marshmallows, bread, even a cassette tape [it was there, I had a bag, now I have a vacuumed cassette tape.]
