Construction and civil engineering: Polypropylene high tenacity yarn is often used in civil engineering to make geotextiles and geogrids, which help to reinforce soil, prevent erosion and can be used in the construction of infrastructure such as roads, bridges and dams. It can also be used to make construction safety nets to provide security at construction sites. 

Fisheries and agriculture: Polypropylene high tenacity yarn is often used in fisheries to make fishing nets, breeding nets and other products that need to withstand the impact of water currents and the struggles of fish. In agriculture, it can be used to make agricultural land film, sunshade net, etc. to help crops grow. 

Packaging and logistics: Polypropylene high tenacity yarn can be used to make high-strength packaging materials, such as woven bags, container bags, etc. These materials can withstand the weight of heavy objects and the impact during transport. It can also be used to make logistics labels, seals, etc. to ensure the safety and integrity of goods.
