Store opened film rolls in cool, dark spaces away from direct sunlight. UV rays degrade polymer structures, causing brittleness and discoloration. Use opaque containers or closed cabinets for additional light protection.

Maintain low humidity environments using dehumidifiers if necessary. Keep film away from water sources and heat-generating equipment. Ideal storage temperatures prevent softening (from heat) or brittleness (from cold).

Seal exposed ends tightly after each use with plastic wrap or sturdy tape. Avoid stacking heavy items that could deform rolls. Store upright to prevent pressure damage and maintain film integrity.

Implement first-opened, first-used inventory management. Even with proper storage, opened film gradually degrades - prioritize its use within 6 months. Regular inspection helps identify early aging signs.
