What plasticizers could you recommend for Cellophane. How to plasticize Cellophane - at some stage of film manufacturing ? or via swelling ?
There is no pressing need to plasticize cellophane since it does not come out rigid when it is formed. We plasticize P.V.C, for instance, because it comes out as inflexible product when it is made from its monomer.
In the attached link, the company uses cellophane ,without any plasticizer, for packaging cheese. I think they are doing a fine job.

You are right: in case of packing - no plasticizer is needed. But we are trying to regulate the permeabiity of membranes made of cellophane.
Since the aim of research is what you mentioned, then I recommend trying adipates (such as dibutyl adipate or dioctyl adipate) or sebacates (such as dibutyl sebacate or dioctyl sebacate). I do not recommend the famous aromatic compound D.O.P "dioctyl phthalate" because it brought problems to a PVC industrial plant here some years ago.
Dear Nizar:
Thank you for your advice. I will try the adipates as you recommended.

Hi Leonid:
How's the adipates work? I am also looking for a plasticizer for cellophane. Would be great if that works out for you.
