The film is on a [[polyethylene naphthalate]] (PEN) base,<ref name=PopPhoto-9601/> and is wound on a single spool, housed in a [[plastic]] cartridge {{cvt|39|mm}} long. The PEN base is both thinner and lies flatter than traditional film base.<ref name=PopPhoto-9611/> In cross section, the cartridge resembles a [[squircle]] with varying corner radii. The basic diameter across one diagonal is 21&nbsp;mm, while the basic diameter across the opposite diagonal measures 30&nbsp;mm, including the corner slot where the film exits.<ref name=Kodak-About/> The slot is protected by a lightproof door. It is available in 40, 25 and 15 exposure lengths.

The film includes a transparent magnetic coating over the entire rear surface; information is recorded on narrow tracks near the edge of the film.<ref name=Kodak-FAQ/> Each frame has four tracks: two below the frame, reserved for the camera, and two above the frame, reserved for the photofinishing equipment.<ref name=Kodak-About/> Some APS cameras use this coating to record exposure information via the IX system.

APS simplifies film handling by allowing the camera to wind the film automatically when loaded, and similarly by rewinding automatically after all the exposures have been taken; some cameras also can rewind partially exposed film cartridges, allowing them to be removed and used later. Numbered symbols (called 'visual indicators') on the cartridge end indicate the status of the film cartridge:<ref name=Kodak-About/>
[[File:IX240 Indicators.jpg|thumb|Visual indicators on an APS cartridge; this cartridge is in state 4 (fully exposed and developed)]]
# Full circle: Unexposed
# Half circle: Partly exposed
# Cross sign: Fully exposed but not processed
# Rectangle: Processed

Additionally, a tab on one end of the cartridge indicates that the cartridge has been processed. On the end opposite the visual indicators, a reflective bar code-like system is used to indicate precise film speed (at release, coded from ISO 25 to 1600), type (reversal or negative), and number of exposures; for simpler cameras, a mechanical notch indicates if the film speed is greater than or less than ISO 200.<ref name=PopPhoto-9603>{{cite web |url=https://books.google.com/books?id=7BPJaraVKOUC&pg=PA28 |title=Advanced Photo System |first=Herbert |last=Keppler |author-link=Herbert Keppler |date=March 1996 |pages=28–34;100 |magazine=Popular Photography |access-date=18 October 2024}}</ref>{{rp|29}}
