1. Introduction to Leno Mesh Bag
Leno mesh bag is a type of packaging designed from synthetic plastic fibers, such as polyethylene (PE) or polypropylene (PP), woven into characteristic meshes. The mesh structure creates high ventilation, which is an important factor that helps mesh bags be widely used in the preservation and transportation of agricultural products, food, and industrial products that require ventilation and long-term preservation.
2. Characteristics and Structure of Mesh Bags
2.1 Material Structure
Mesh bags are often produced from synthetic plastic fibers with good durability and resistance. The outstanding structural feature of mesh bags is the cross-woven mesh with uniform meshes, thereby creating much better ventilation than sealed packaging.
2.2 Mechanical Features
Leno mesh bags often have important mechanical properties:
Tensile strength: Helps withstand large product weights and reduces the risk of tearing during transportation.
Tear resistance: Prevents tearing in the longitudinal or transverse direction when impacted.
Abrasion resistance and compressive strength: The mesh structure helps the bag withstand compression during transportation and storage.
2.3 Ventilation and Drainage
Leno mesh bag has a structure that allows air and water vapor to easily move back and forth, helping to keep agricultural products from getting wet, limiting the risk of rotting. This feature is especially important in preserving fresh agricultural products such as potatoes, onions, garlic, and products that need to be kept dry.
3. Applications of Mesh Bags in Industries
3.1 Agricultural Products
Leno mesh bag is a popular choice in the agricultural industry for packaging and preserving perishable products that require ventilation such as:
Potatoes, onions, garlic: Helps reduce humidity and preserve longer.
Fruits: Used for fruits with hard shells or that can withstand light impacts.
Other fruits and vegetables: Keep products fresh, minimize bacteria or mold growth.
3.2 Seafood and Processing Industry
Mesh bags are also used in the seafood industry to preserve and transport frozen foods, helping to easily release water vapor when thawing and minimizing the situation of condensation causing spoilage of products.
3.3 Construction Materials and Industry
Some types of mesh bags are used in the construction industry to package and transport materials such as seashells, oyster shells, or materials that are sensitive to moisture.
4. Advantages and Disadvantages of Mesh Bags
4.1 Advantages
Low cost: Compared to packaging made from other materials, mesh bags have lower production costs, helping to save packaging costs.
Easy to use and store: Mesh bags are light, easy to transport and stack, and can be reused many times.
Environmentally friendly: Some types of mesh bags are recyclable, minimizing negative impacts on the environment.
4.2 Limitations
Limitations on the volume of the bag: Mesh bags are only suitable for light or medium weight products. For heavy products, a special mesh bag design is required to ensure strength.
Limited protection: The mesh structure cannot protect the product from strong impacts or dirt from the outside environment, so it is not suitable for some products that require sealed storage.
5. Popular Types of Leno Mesh Bags
PP (Polypropylene) mesh bags: A popular type of bag with high durability, good chemical resistance and abrasion resistance. PP is light weight, high tensile strength and easy to manufacture.
PE (Polyethylene) mesh bags: Good toughness, water resistance, but mechanical strength is lower than PP. PE is often used for products that require short-term storage.
Combined mesh bags (PP/PE): This type of mesh bag combines the best properties of both materials, providing flexibility and durability for many different applications.
6. Market and Development Potential of Mesh Bags
The leno mesh bag market is growing rapidly due to the increasing demand for preserving agricultural and industrial products. Especially in large agricultural producing countries, mesh bags are a cost-effective and environmentally friendly solution.
6.1 Market Trends
Increasing environmental friendliness: With the growth of green and sustainable trends, mesh bag manufacturing companies are developing bags from recycled or biodegradable materials.
Improved technology: Mesh bag manufacturing technology is being improved to reduce weight while still increasing durability, saving raw materials and minimizing costs.
6.2 Development Challenges
Competition with other types of packaging: Other types of packaging such as paper bags and flexible plastic bags are also being improved with environmentally friendly features, requiring mesh bags to have a high competitive advantage.
Climate change and storage requirements: Changes in storage and transportation conditions also require mesh bags to be flexible to accommodate harsher conditions.
Mesh bags (leno mesh bags) play an important role in the storage and transportation of goods due to their breathability, high durability, and low cost. With the trend of developing green technology and increasing competition, mesh bags have the potential to grow strongly in the future. However, to maintain a position in the market, it is necessary to
