Polypropylene woven bags are a common type of packaging material with the following characteristics:

- Lightweight: The density of polypropylene is approximately 0.9-0.98 grams per cubic centimeter, which is lighter than water. The woven bags made from it are lightweight, making them easy to carry and transport.

- High strength: The molecular chain structure of polypropylene gives it high hardness, strength, and rigidity. The woven bags have high tensile strength, can withstand large pulling forces, are not easy to break, and are suitable for packaging heavy items such as chemical fertilizers and cement.

 Waterproof and moisture-proof: Polypropylene itself has a certain degree of waterproofness, and its moisture-proof and waterproof performance can be further enhanced by means such as laminating or matching with PE inner bags, effectively protecting the items inside the bag.

- Good air permeability: The woven structure gives it a certain degree of air permeability, which is beneficial for the storage and transportation of items that require ventilation, such as agricultural products, and can prevent items from getting moldy and deteriorating due to moisture.
