Could be a couple......
Originally it was frowned on using plastics as there was an issue with the plasticisers leaching out into the liquid.
These days its been found that many plastics are slightly air permeable over time so you can use a bucket made from hdpe for fermenting or the "better bottle" plastic carboys which are made from PET. But its still recommended to get and longer term ageing done in glass.
Or of course if you intend using any vacuum during the processing then most plastics are a no-no.....
Could be something to do with those...
