I am interested in the clear plastic tubes 350 mm x 21/2''. I assume that they have a bottom as in a bottle is that correct. Can you get a screw on top that is airtight (does it have a rubber seal). What is the thickness of the wall?
The tubes we have in Australia close to the size requested is a 2-1/2" diameter x 304.80mm in Length. This tube is open at both ends. We have a clear cap and black vinyl end cap to close the ends of the tube. We do not have a rubber seal or screw on cap. The wall thickness of the tube is 0.71mm.
We can manufacture in the USA, a sealed bottom tube to the length of 350mm. I have attached the link to our website for a 2-1/2" x 10" tube and the suitable caps to this item as an example. Please let me know if you would like a quote on the items mentioned.http://store.visipak.com/2-1-2-x-10-Medium-Wall-Round-Permaseal-II-Sealed-Rigid-Bottom-Container-544074.html Kind regards, Lauren
