Polypropylene (PP) Fabric Bags are essential in various industries, including agriculture, construction, food packaging, and waste management. These versatile, durable bags come in multiple designs and sizes, making them suitable for transporting and storing materials ranging from chemicals to pet food. This article delves into the different types of PP fabric bags, their key specifications like thickness, weight, and size, and the strength they can handle. We will also explore how Woven bags are customized to meet different client requirements, and why understanding these parameters is crucial for optimizing your packaging solutions.
1. Types of PP Fabric Bags and Their Applications
PP Fabric bags come in several formats depending on the intended use. These bags are made from woven polypropylene fabric, which offers excellent durability and flexibility. The most common types of PP sacks include:
- BOPP Laminated Woven Bags
- Kraft Paper Woven Bags
- Valve Bags
- Jumbo Bags (also called FIBC bags)
- Tubular Woven Bags
Each type serves specific purposes:
- BOPP Laminated Woven Bags are used in packaging food, agricultural products, and pet food because of their excellent printing capabilities and resistance to wear and tear.
- Kraft Paper Woven Bags are ideal for packing bulk products such as grains and fertilizers. Their combination of paper and polypropylene offers extra strength.
- Valve Bags are perfect for powders and fine-grain products, providing an easy filling mechanism and preventing leaks.
- Jumbo Bags (FIBC) are used for bulk materials like sand, gravel, and chemicals, thanks to their large size and capacity.
- Tubular Woven Bags are great for stacking and palletizing large quantities of materials.
2. Key Product Parameters: Thickness, Weight, Size, and Strength
When selecting Woven bags, understanding their parameters—such as thickness, weight, size, and weight-bearing capacity—helps you determine the right product for your specific needs. These factors are crucial for ensuring the bag’s durability, performance, and ability to handle certain loads.
Thickness
The thickness of PP fabric bags typically ranges from 70 microns to 200 microns, depending on the material’s intended use. Thicker bags provide greater resistance to punctures and tears, while thinner bags are lighter and cost-effective for lighter products.
| Bag Type | Typical Thickness |
|---|---|
| BOPP Laminated Woven Bags | 100 – 150 microns |
| Kraft Paper Woven Bags | 100 – 180 microns |
| Valve Bags | 80 – 150 microns |
| Jumbo Bags (FIBC) | 120 – 200 microns |
| Tubular Woven Bags | 80 – 150 microns |
Weight (Grammage)
The grammage of PP Woven Sacks refers to the weight per square meter of fabric. It is essential for determining the bag’s durability and strength. A higher grammage typically means more robust, heavier bags that can carry greater loads.
| Bag Type | Grammage (gsm) |
|---|---|
| BOPP Laminated Woven Bags | 90 – 200 gsm |
| Kraft Paper Woven Bags | 120 – 250 gsm |
| Valve Bags | 80 – 180 gsm |
| Jumbo Bags (FIBC) | 150 – 300 gsm |
| Tubular Woven Bags | 80 – 180 gsm |
Size
The size of Woven bags is highly customizable, based on the client’s packaging needs. Common sizes range from small bags used for grains to large bags designed for bulk material transport. Jumbo Bags, for instance, are available in sizes that can carry up to 2000 kg of material.
| Bag Type | Standard Size |
|---|---|
| BOPP Laminated Woven Bags | 10 – 80 kg |
| Kraft Paper Woven Bags | 10 – 50 kg |
| Valve Bags | 5 – 25 kg |
| Jumbo Bags (FIBC) | 500 – 2000 kg |
| Tubular Woven Bags | 5 – 50 kg |
Weight-Bearing Capacity
The weight-bearing capacity of PP fabric bags is a critical parameter for industries handling heavy-duty materials. Depending on the bag’s design, material, and size, the load capacity can vary.
| Bag Type | Load Capacity |
|---|---|
| BOPP Laminated Woven Bags | 25 – 50 kg |
| Kraft Paper Woven Bags | 25 – 50 kg |
| Valve Bags | 25 – 50 kg |
| Jumbo Bags (FIBC) | 500 – 2000 kg |
| Tubular Woven Bags | 10 – 50 kg |
