Embodiment 1
[0022] A kind of manufacture method of inner mucous membrane woven bag, inner mucous membrane woven bag such as image 3 As shown, it includes a plastic outer bag 9 woven from polypropylene plastic, and an ethylene-vinyl acetate film layer 10 and a high-pressure low-density polyethylene film layer 11 are sequentially provided in the plastic outer bag 9;
[0023] Including the following steps:
[0024] A. Making plastic flat wire: Extrude polypropylene plastic particles into plastic strips through a plastic extruder, and the plastic strips are cooled and cut into slices, heated and stretched to make plastic flat wires for later use;
[0025] B. Making double-layer films: heat, melt and plasticize ethylene-vinyl acetate plastics and high-pressure low-density polyethylene plastics, and extrude them through a double-layer co-extrusion blown film machine to form a cylindrical outer layer. The ethylene-vinyl acetate film layer 10 and the inner layer are double-layered films of the ...
