The utility model provides a portable braided bag of PPPET microfibril enhancement mode, by constituteing at the bottom of handle, braided bag body, the centre of a circle type braided bag, PPPET microfibril reinforcing silk is woven at the bottom of braided bag body and the braided bag, the handle is connected with the top of braided bag body, link together through the meander configuration organizine at the bottom of braided bag body and the centre of a circle type braided bag to pass the offside that extends to the braided bag body at the bottom of the type braided bag of the centre of a circle. Be that centre of a circle type structure is taked to the bottom of braided bag to the bearing region of braided bag, can increase a bag body capacity, take meander configuration PPPET microfibril reinforcing silk to weave the improvement supporting power, overcome the object and leaded to the impact force to cross the shortcoming that the braided bag bottom was worn in the attack owing to put into the braided bag fast accomodating the in -process.
