What if I screw up or cant do it after opening the bulk film? Does it come with a resealable zip lock so that I put it back and turn lights on??
Imagine a paper till roll in a shop cash register. It's that simple. You can feel the end of the film by running your fingers over it. With the film end at the top, you want it pointing left. Detach and remove the little bit of tape holding it down; feed it through the slot on the loader.
Suggestion: sacrifice an old roll of film. Strip off the cassette. Use the unrolled film to practice feeding the film into the loader.
Bulk rolls are normally packaged in a heavy black plastic bag (no ZipLoc) which in turn is inside a light-tight tin or black plastic drum sealed with tape to stop the lid coming off. It's very easy indeed to put the film back in the bag and the bag back in the tin. Tape the tin shut so the lid doesn't come off! You can put the tape on in daylight.
In the last picture in the link to my site, you can see an almost-finished (and by then hopelessly exposed!) roll of bulk film on its centre core, which will be either plastic or cardboard.
