For retort bag, first you need to figure out you will retort the bag in water or in high voltage machine, also time limit is also a big element. If you just retort your bag into water, then at most 100 degree, then Nylon/common RCPP will be ok, while if in high voltage machine, then we need to use Nylon/higher level RCPP. Also pls tell us the time you will retort the bag, then we can give the best suggestion.
