All movies and reels have to be stored in an efficient manner so that they can be maintained for a longer period and can be reused when required. Vented film cans are just another form of storing films. They have major advantages due to which they are preferred:
•
They significantly improve airflow under the
film, reducing acetic acid levels which extend the lifespan of the film
•
They are built with raised ribs to provide solid
and even support throughout the film roll, thereby preventing film sagging and
edge distortion.
•
They have platform designs which make them easy
to store and can be stacked or un-stacked with less labor effort.
•
The finishing of Vented film cans is smooth and suitable for long-term.
A-D strips are known as Acid detection strips. They are
dye-coated paper strips that detect and measure the severity of acetate film
deterioration, a.k.a. vinegar syndrome, in film collections. The strips are
sold in packages of 250 and come with a user's guide. When placed inside a
closed can, bag, box, or cabinet, A-D
Strips change color in the presence of the acidic vapor given off by
degrading film. As the level of acidity increases, they change from their
original blue color through blue-green, green, and yellow-green, and finally to
bright yellow. Use AD Strips to
learn the approximate extent of acetate degradation in individual films, or use
them as a survey tool for gaining an overview of film condition in an entire
collection and to get a more accurate picture of storage and duplication needs.
