is tyvek better than pollyfill?


-------------------------------------------------- ------------------------------


depends on the quality of the tyvek used.
that post office stuff is mostly paper
and i don't like it, quit using it long ago.
polyfil is a synthetic fiber too
so it shouldn't support growth,
the main problem folks have with polyfil is that it protrudes into the jars,
making it easy to get it wet when shaking jars.
now if the water contains nutes,
that will cling to the polyfil and
yep, contams will grow down thru it
into the jar.
tyvek is flat and so is easier protected from such.
i personally use a three-part filter on my qts,
a layer of good tyvek on top the lid,,
then a polyfil plug for the lid hole,
then another layer of tyvek under the lid.
the layer under the lid compresses the polyfil, keeping it up high and is water-resistant
so the polyfil is protected.
then the polyfil acts as a filter
after the tyvek is punctured by injection,
extra redundancy but my environ is very high contam so extra precautions pay off.


archive material to lids, etc.
