Fabric Poly Bags, commonly referred to as Woven Poly Bags or PP Woven Sacks, have emerged as a preferred packaging solution across various industries due to their durability and versatility. These bags are especially beneficial in packaging seeds, nuts, grains, rice, soybeans, wheat, corn, coffee beans, starch, and processed agricultural products. Understanding the specific requirements for each application is crucial for optimizing packaging effectiveness.
In this article, we will analyze the different needs based on product thickness, weight (grams per square meter), size, bag types, surface coatings, and the inclusion of inner bags, illustrating how these factors influence the choice of packaging materials.
Properties of Woven Poly Bags
Before delving into specific applications, let’s first explore the general attributes of Fabric Poly Sacks. Woven Poly Bags are made from polypropylene (PP) yarn, woven into a strong fabric that offers excellent tensile strength and resistance to tearing. They can be produced in various weights and thicknesses to suit different applications. Below is a comparison table that summarizes key parameters of Woven Poly Bags:
| Parameter | Typical Range | Description |
|---|---|---|
| Thickness | 50-150 microns | Thicker bags offer greater durability and resistance to punctures. |
| Weight (GSM) | 60-200 grams per square meter | Heavier bags are more suitable for bulk storage and transportation. |
| Size | Customizable (e.g., 25kg, 50kg) | Size depends on the volume of the product being packaged. |
| Bag Type | Valve bags, open mouth bags | Valve bags are preferred for bulk materials; open mouth bags for easier filling. |
| Surface Coating | Coated or uncoated | Coated bags offer moisture resistance; uncoated bags are more breathable. |
| Inner Bags | Optional | Inner bags can provide additional moisture protection. |
This table serves as a foundation for understanding how specific applications can demand variations in these parameters.
Specific Requirements for Various Applications
- Seeds and Grains
- Thickness and Weight: Seeds and grains are often sensitive to moisture and physical damage. Woven bags for these products typically range from 80-120 GSM, providing a balance between strength and breathability.
- Bag Type: Valve bags are ideal as they allow for quick filling and minimize dust exposure.
- Coating: A moisture-resistant coating is beneficial for maintaining seed viability.
- Nuts
- Thickness and Weight: Nuts require protective packaging that prevents crushing. Bags with a thickness of around 100-150 microns are ideal, with a GSM of 80-120.
- Bag Type: Open mouth bags are commonly used for retail, while valve bags work for bulk.
- Inner Bags: Consider using inner bags to protect against oil seepage.
- Rice and Grains
- Thickness and Weight: Rice packaging often necessitates bags that can hold a weight of 50kg, with a thickness of 100-120 microns for strength during transportation.
- Coating: Waterproof coatings are essential to prevent spoilage from moisture during storage.
- Bag Type: Valve bags are frequently used due to their convenience in filling.
- Soybeans and Wheat
- Thickness and Weight: These commodities benefit from bags with a thickness of 70-100 microns, with GSM ranging from 60-100.
- Coating: Coatings help reduce exposure to pests and moisture.
- Bag Type: Valve bags facilitate the quick filling process.
- Corn
- Thickness and Weight: Corn bags typically range from 100-150 GSM, ensuring durability.
- Coating: Protective coatings can help in managing moisture content during storage.
- Bag Type: Open mouth bags may be used for retail environments.
- Coffee Beans
- Thickness and Weight: Coffee bags often require 150-200 GSM bags due to the weight and sensitivity of the beans.
- Inner Bags: Inner bags are critical for freshness and preventing exposure to air.
- Coating: A moisture barrier is essential to keep the beans fresh.
- Starch and Processed Agricultural Products
- Thickness and Weight: Products like starch may require bags ranging from 70-150 GSM, with sufficient thickness for structural integrity.
- Bag Type: Valve bags are often used due to ease of filling.
- Coating: Products sensitive to moisture benefit from a protective coating.
Conclusion
Fabric Poly Sacks, particularly Woven Poly Bags, offer a versatile and durable solution for a wide range of applications. By tailoring the thickness, weight, size, type, coating, and additional features of these bags, businesses can ensure optimal protection and preservation of their products.
The adaptability of Fabric Poly Bags positions them as essential tools in the agricultural packaging industry, supporting the safe transportation and storage of various commodities while enhancing operational efficiency.
