Design and production process of big bag:
The design of ton bags should strictly follow the standards. Tons of bags are used as export packaging, and it is necessary to ensure that the exported goods are protected during loading, unloading, transportation and storage, and the goods are transported to the destination in good condition. Therefore, the design of the ton bag meets four main points, namely safety, storage, usability, and sealing.
The production method of the ton bag is to use polypropylene as the main raw material, add a small amount of stable condiments and evenly mix, melt and extrude the plastic film through an extruder, cut into filaments, and then stretch, and heat-setting to make high-strength low-strength plastic films. The PP raw silk with the elongation rate is then woven and coated to make the base cloth of the plastic woven cloth, which is sewed with accessories such as slings to make a ton bag.
