Re: [Killietalk] Heat sealing of Kordon plastic bags

Hello Erik

You might try playing around with the sealing time.

You might be over heating the bag.

Another place you can get leaks is where the bag of water ends and the seal
begins.

If you move the bag to soon or pull from the water side of the seal you tend
to get leaks.  

I always pull the bag off from the side that does not contain the water.

You may also get faulty sealing if there is water on the area to be sealed.

Subject: [Killietalk] Heat sealing of Kordon plastic bags

I got a question about the heat sealing of Kordon plastic bags. I got a
small heat sealer bought in the Philippines. But when I seal off plastic
bags they tend to leak. 

Now, Wright Huntley mentioned black vinyl electrical tape. Do you first tape
the plastic bag and then heat seal it? Or the opposite or what? 
I find the Kordon plastic bags fragile to handle and only tested few times
so any tips are helpful. Still got 70+ or so to go.
Sincerely,
