Polaroid has made various pack film types over the years. Even though some of the pack film cameras had settings for 75, 150, 300, and 3000 ASA film, Polaroid only produced 75 (and 80) and 3000 speed film for these cameras. Because the picture resulting from pack film is just like a normal print (as opposed to an integral print, such as SX-70 film) and can be cropped or laminated, other types of film (also listed below) were produced with different speeds for studio and scientific work. Though these film types weren't designed for the pack film cameras in this collection, they would probably work with the correct exposure compensation. All films listed here are in a 3 1/4" x 4 1/4" pack format with an image area of 2 7/8" x 3 3/4". Earlier film packs had 8 exposures per pack but all new packs have 10 exposures. Here's a chart listing the different films. Notice how they skipped over the number "666"? Polaroid is ceasing production of all its film in 2009.
The following table only shows pack films which Polaroid has produced:

|100||colour||100||90 sec.||customizable UV security logo|
|107||B&W||3000||15 sec.||needing coating|
|108||colour||75||60 sec.||balanced for daylight or flash bulbs|
|Studio||colour||125||90 sec.||medium contrast, accurate colours|
|64T||colour||64||90 sec.||balanced for tungsten light (3200ºK)|
|611||B&W||N/A||45 sec.||low contrast with extended range, for video recording|
|612||B&W||22,000(!)||30 sec.||high contrast for CRT applications|
|664||B&W||100||30 sec.||fine grain, medium contrast|
|665||B&W||3000||30 sec.||produces a usable negative|
|667||B&W||3000||30 sec.||available in 20 packs!|
|668||colour||80||60 sec.||balanced for daylight or electronic flash|

|690||colour||125||90 sec.||more latitude in development time/temperatures|
|691||colour||80||4 min.||transparency for overhead projection|
|672||B&W||400||45 sec.||medium contrast, fine grain|
|679||colour||100||90 sec.||lower contrast than type 100|
|689||colour||100||90 sec.||"pro vivid" film—higher colour saturation|
Polaroid discontinued production of all film in 2009. Fujifilm, which continued making 100 series pack film until 2016, has also discontinued production of all their instant pack film. A kickstarter called One Instant is selling handmade single exposure packs using old negative stock for around $15/photo, but the results are mixed (colours and uneven reagent spread). Polaroid (formerly Polaroid Originals/Impossible project) has filled in the gap by producing SX-70, 600, and 8x10 (!) film in both colour and black and white. Their 600 film is also available with various border colors and decorations. Although Polaroid has made film available, it is not the same as what you might expect from SX-70 Time Zero or 600 film from Polaroid. Colours are more subdued and development time is slower. Currently, black and white film takes around 10 minutes to fully develop. Colour film takes around 15 minutes.
Sometimes you can find outdated film on Ebay. At this point in 2021, any Polaroid film will be at minimum 13 years past its expiry date, and will ususally sell for $70/pack or more. There is no way to guarantee this film will work at all, since the chemicals used for processing start drying up after 5 or so years. If the film has been in cold storage, the chemicals will likely be OK, but colors will shift and the thickness of the chemicals will mean uneven spreading resulting in incomplete coverage. This can provide a unique artistic look which you may or may not be seeking. Fuji pack film is still viable if you manage to find some of the last batches, which expired in 2018.
One of the biggest problems with film that is out of date for more than 2 years is that the chemicals used for developing dry up. This happens slowly, so if you are using 2 or more year outdated film, you may notice that when you peel apart the film after developing, the chemicals didn't spread over the whole print. On very outdated film (5+ years), the chemicals may be totally dried up so that the print falls away from the negative right after pulling it from the camera. Another problem with outdated integral film (SX-70, 600, 500, and Spectra film packs) is that the battery will not have enough power to run the camera or even eject the film.
When you use outdated film, you may need to experiment with exposure compensation and development times. Outdated film may need a slight increase in exposure and longer development times and different film types will shift in colour. 690 film is known to shift to yellow, while 669 shifts to green.
The best place to store film is in a cool dark place. A fridge is ideal, as long as it doesn't have a reputation for freezing your veggies! Before using, you will need to warm it up at room temperature for a few hours.
