The outer layer of the tarpaulin is a waterproof fabric that is wrapped in a bulletproof panel on the surface.
It has the characteristics of simple processing and low price. The polyurethane coating is evenly sprayed on the surface of the bulletproof plate, the polyurethane coating will bring additional weight, compared to the waterproof cloth outer layer will weigh about 200g. But it can also play a certain defensive effect, and the bullet hole after the bullet is also smaller than the bag cloth as the surface of the bulletproof plug plate bullet holes. But the price of the plug plate using the polysacchabet coating will also be more expensive than the use of tarpaulin outer plate, the specific choice can only depend on the individual's needs.
