Both work well but 80 gauge is better for small parachutes.
Yes, you can use thin and flexible poly bags also.
It depends on size and numbers of flares and you have to fix it by trial and error.
Hand crape-ing is a simple technique which makes the tissue flexible like cloth.
Take a high quality virgin tissue paper and cut it into the desired size then squeeze it with your palm to make it a ball and roll the paper ball with both of your palms for a while then stretch out the curled paper ball with patience against a flat surface. Squeeze it again to make a ball, roll and then stretch out and repeat the process for a fewer turn till the paper appears like a cloth. Bad tissue papers may tear off during the process but a good one wouldn't.
