shipping bags

[johnjr]

Just wondering if there is a certain type of bag to use when shipping livestock?
Would these work:http:
www.aplasticbag.com/items.asp?CartId=7342792-ACCWARE-DJTZW688&Cc=FLAT3&tpc=

They are made of polyethelyne and gas permeable(not sure if that is a bad thing). They do not gaurantee them to be water tight.

Any other suggestions would be helpful.

Thanks.

I think the plastic needs to be linear polyethylene(high density). It is much stronger, but more expensive. Aquatic ecosystems sells these bags but there a little expensive.http://www.aquaticeco.com/aquatic1v1/itempg.icl?secid=0&subsecid=162&catid=1894&orderidentifier=ID10492211714333A3F25&itmid=1862&dirpage=dir3&iteminfo4=0&eflag=0&curitempos=4&numitems=12
