    Where to get mylar to protect negatives

    Hello,
    after I got a tiny spot of kallitype emulsion on my film I am trying to get some thin mylar (0.003inch/76.2 microns) to put between the negative and the sensitized paper. Couldn't find anything locally.
    Any ideas where to look for such a thing?

    THanks!

    Do you mean acetate? A good art store/supply shop should carry it.

    Andreios, try flower shops; they usually have pretty thin (thickness: 2 mils / 50um) clear polyester film for packing bouquets. Anything above 50um is not much advisable, starts to significantly harm sharpness. (50um is about right, as thin as it can get w/o getting too hard to handle - such as cling flim...)

    Hope this helps,
    Loris.

    I've used plastic food wrap, the type that clings to itself. It is very thin, though not aways easy to handle because of its clinging property.

    What a great idea! Print files also work well.

    Yes Andrew, protective sleeves do indeed work well as long as their thickness <= 3mils.

    Hi Mustafa, you don't need extremely durable / hard to find exotic stuff. A sheet used as impermeable protective barrier between the coated paper and negative isn't normally reused for more than 2-3 times at maximum. All you need is a film that is very clear, thin (<= 3mils) but stilll easy to handle and transparent to UV. BoPET is cheap, easy to source and perfect for the job.

    Regards,
    Loris.

    The print sleeves (called protector sheets) I get from my local art store are very thin.

    No. Mylar is a DuPont trade name fpr their polyester products.

    Make sure you ask for the right type as it's available in white and semi-opaque as well as clear.

    If you just want a few sheets, I could send you some.
