Seamed Volcano bags/balloons
Posted: Thu 11th Jul 2019 12:45 pm
I'm talking about the polyester tube that is cut to length for 'solid valve' rather than the ready made 'easy valve' variety.
My Volcano is so old that the roasting bag tube that came with it originally was branded with a German food company. These days the bags are branded 'Volcano'.
The pump on my Volcano seems weaker than on more recent models so even a small hole in the bag, such as that punched by the hot tip of a joss stick touching it, is enough to stop it working.
Just recently I've had instances of splits occurring spontaneously near the tie at the top of the bag. On investigation I've found that this is due to a seam along the length of the tube opening up. Following these issues I tried taping up the seam before making a bag and that helped a lot.
I don't recall there being a seam on these tubes in the past so I decided to order a new roll from a different supplier. This has just arrived and I see that this tube also has a seam.
So the question is: have these tubes always had a seam? Maybe I haven't noticed before and maybe the previous batch I had was faulty. Alternatively, should genuine Storz and Bickel tubes be seamless and have I found a counterfeit supply?
Thanks for any thoughts.
