Sealing a Sealline dry bag

[Marmot]

I've been playing around with my dry bags and worryingly when i stood on one i could hear the hiss of air escaping. If air can go out then obviously water can come in.
So after messing around a bit more ive perfected the best way of closing a sealline dry bag.
http://www.seallinegear.com/vinyl_bags.asp?Action=SeeBag&Category=VinylDryBags from there u can use the separate link to see the closure system.

On the black strips are the closing instructons. And supposedly you should Fold a to b.
What i propose you do is fold it the other way folding together "2. Tightly fold again" to "3. Tightly fold again. Connect bucckle. D ring out" and then fold over twice more so that no more of the black strips can be seen.
Also. as u can see from that link there is a flap of plastic at the mouth of the bag. Fold that first so that its trapped between "2. Tightly fold again" and "3. Tightly fold again. Connect bucckle. D ring out"

If you can folow that id be impressed, obviously it makes sense to me, but its worth playing around with your kit as the instructions given may not be the best way of doing things.
The onl down side is the d ring is now facing inwards, but its still accesible for use.

And yes when i stand on it now air does not come out - so it wasnt my fat weight in the first place!

I suspect the pressure of you standing on the bag would be greater than the pressure that the bag is likely to suffer in normal use. However, your improved way of sealing the bag should prove invaluable if you are using one at depths of over 200 metres!

Is it better to leave some air in them when using them?

I thought it probably would be, for example if you are using them kayaking and capsize they will float to the top rather than sink to the bottom..?

Indeed it is Ollie! Air can be compressed, however solids and liquids can't (in general), so the air in the bag actually makes it less likely to explode on compression. The same is true of bottles of liquid when freezing, the air gives a sort of buffer to the expansion of the liquid.

God I rattle on at times! hehe

Welcome back btw!

Surely, you mean IMplode?

if u use a dry bag in your rucksac squeas the air out but if using it on water fill it with air so it floats

I've got a sealine dry bag, however when putting it out to dry after a quick wash down. Going outside to put my gear away, i noticed that my neice and nephew, decided to take the bag away with them (mainly downstairs) found a load of rocks with sharp edges and thought it would be a good idea to fill my nice clean only been used once dry bag with as many rocks as they could, which they did. NOW!! i have a nice hole in the bag and in need of repair :( (my reaction wasnt nice, as you can imagine)

Any ideas of what i can use to repair my bag so it can be fully used once more.

Maybe you could try using one of those Goretex patches they sell to repair clothes? They're already sticky, so you just put them over the hole & iron them on.

Alternatively, some plastic or nylon sheeting coupled with superglue might do the trick, or there's always gaffa tape!

was thinking of using a bike repair kit?? dont know if it would hold up to the battering of rocks... dont like using superglue at the best of times, is there anything that has been tried and tested as i wouldnt want water getting into the bag, more so when i've got a digi cam in there.

I'm far too cheap to buy a dry bag so I usually use a rolled up plastic bag. Never had any problems with that!

I did get a small dry bag as a "secret santa" present from work but it's only small so it just gets used for headtorch & car keys - no punctures yet.
