Callatya Posted March 28, 2009 Report Share Posted March 28, 2009 Hey all, I ended up in a catering & packaging supply shop last week and on top of all the fun cups, jars and doohickeys that I was just itching to play fishies with, they had an entire rack of foodsafe plastic bags. I bought a pack of small ones to trial as they had a folded base and side seams and they worked rather well. On the way home I dropped past my folks' place and Dad mentioned that he thought the micron size was not ideal for liquids. They aren't really under pressure, we are hand bagging rather than using O2 canisters, so I'm not that worried but I was wondering what micron size normal fish bags are, and if anyone has ever had a problem with this. These were 35um, apparently we should be aiming for 50. Myself, i'm more interested in how the seams will work as I think fishbags generally are tubular and have a single sealed base seam, but I guess we'll see ;) Link to comment Share on other sites More sharing options...
Anasfire Posted March 28, 2009 Report Share Posted March 28, 2009 if you are concerned just double bag?? Link to comment Share on other sites More sharing options...
splendidbetta Posted March 28, 2009 Report Share Posted March 28, 2009 What does the micron size refer to? The pore size? In that case, shouldn't smaller (35) be better? I'd be more interested in overall tensile strength, and the seam pressure resistance. Link to comment Share on other sites More sharing options...
Chuckie Posted March 28, 2009 Report Share Posted March 28, 2009 The plastic is nice and 'rubbery' (for want of a better word) as opposed to the rather brittle consistency of some the small fish bags from a few years ago. They seem to be fairly supple/flexible. Abbey took the first 10 of our spawn home on Tuesday using them with no mishap, but that's only a 45 minute drive. Double bagging is necessary if you're actually shipping IMO, whatever bag you use. Link to comment Share on other sites More sharing options...
splendidbetta Posted March 28, 2009 Report Share Posted March 28, 2009 That sounds good. I test out my bags by filling them up and tying them as usual, and seeing how much squeezing they can take before exploding ;) Link to comment Share on other sites More sharing options...
Chuckie Posted March 28, 2009 Report Share Posted March 28, 2009 I left one inflated and with water in it on the sink, it stayed inflated til I got sick of looking at it and chucked it out before the non-fishy husband complained ;) Link to comment Share on other sites More sharing options...
killimike Posted March 28, 2009 Report Share Posted March 28, 2009 I know nothing about micron size, tensile strength or seams, but the idea of a whole craft shop full of stuff to play fish with is very appealling :)Can I ask, are the bags fairly cheap? Always cool to try something new, how small is small? Betta bag small, or kind 6" by 12" small? Bring some along on Saturday! Link to comment Share on other sites More sharing options...
Callatya Posted March 28, 2009 Author Report Share Posted March 28, 2009 I got a bag of 50 small ones (betta bag small, thought we could use for moving the juvies around rather than waste big bags on small fish) for $2, most expensive was under $12 I think. I reckon it is easy to have a play and find out They are just flat bags though, so you need to tape or tie the corners to prevent squishing. I left the bags at Lilli's place, so I'm sure there'll be some to play with next week I blew one up with air in the car, I squished, it didn't want to burst. The ones with the fish were bagged twice due to a delay, and they still appear to be intact, so that is promising I think the micron size refers to the thickness of the plastic sheet, so a higher number would be thicker plastic. I'll have a look at a few of the larger bags next time, see if they come any thicker as the bag size increases. Link to comment Share on other sites More sharing options...
Fishchick Posted March 28, 2009 Report Share Posted March 28, 2009 all commercially available and utilized fish bags are MINIMUM 50micron - this is the thickness of the bag. Double bag for all spiky fish like catfish and Cichlids. Bettas can go into thinner bags - just double bag if you are shipping. Carrying to a shop is ok in one bag. I have trouble getting rubber bands around bags thicker than 50 micron. Link to comment Share on other sites More sharing options...
