A few companies make small waterproof pouches, they will work for sure.
Research paper on swisseduc.ch says an iron chemical pack will heat up to max temperature in 10-20 min, then will keep high temperature for 2-3 more hours and then cools down quickly. It will be colder than a body temperature after about 4 hours from the moment you open the package. If it was opened for 4+ hours, don’t bother to wrap, the juice is gone.
