Adox ADOFILE 120 Negative sheets are made of high-grade polypropylene.
This multipurpose medium format sheet is big enough so that all sizes of medium format negatives fit inside (6x6, 6x7 and 6x9).
The pages fit in both 3 ring and 4 ring binders. Both ends of the negative sleeves are open, allowing for air exchange. The polypropylene is absolutely chemically neutral and archive-safe.
It is also stable, tear-proof and perfectly clear for easy contact-printing.
Polypropylene files are more stable than those made from acetate and thus easier to load. The slight difference in thickness leads to a theoretical lower resolution of a contact print through the file though (compared to the thinner acetate sleeves).
