What Makes Kraft Paper PP Bags Unique?
The integration of kraft paper with PP woven fabric enhances the bag’s strength while retaining its lightweight nature. These bags exhibit a perfect balance between flexibility and rigidity, making them suitable for diverse applications. Additionally, Paper Valve Woven Bags, which are a subtype of these products, further add convenience through their user-friendly valve design, enabling efficient filling and sealing.
Essential Product Parameters
The functionality and application of Kraft Paper PP sacks largely depend on key specifications. Below is an analysis of thickness, grammage, dimensions, and weight capacity:
1. Thickness
The thickness of the laminated woven fabric determines the durability and puncture resistance of the bag. Typical thickness ranges are as follows:
| Bag Type | Thickness (microns) | Application Example |
|---|---|---|
| Standard Kraft Bags | 80-120 | Retail packaging |
| Heavy-Duty Kraft Bags | 120-160 | Agricultural and industrial use |
| Extra-Strength Kraft Bags | 160-200 | Construction materials |
2. Grammage (Weight per Square Meter)
Grammage, expressed in GSM (grams per square meter), directly correlates to the strength and weight of the bag.
| GSM Range | Strength | Common Usage |
|---|---|---|
| 60-80 | Lightweight | Packaging flour or grain |
| 80-100 | Moderate strength | Pet food packaging |
| 100-140 | Heavy-duty | Industrial materials |
Higher GSM results in increased load-bearing capacity but also adds to the overall weight of the bag.
3. Size Options
The size of Kraft Paper Woven Bags varies to suit different applications. Below are some common dimensions:
| Dimensions (cm) | Capacity (kg) | Usage |
|---|---|---|
| 40 x 60 | 25-30 | Food ingredients |
| 50 x 80 | 50 | Animal feed |
| 60 x 100 | 75-100 | Fertilizer and construction material |
Custom sizes are available to meet specific industrial needs.
4. Load-Bearing Capacity
The ability of a bag to hold weight without tearing or stretching is critical for its application. Here’s a breakdown:
| Bag Type | Load Capacity (kg) | Key Features |
|---|---|---|
| Light-Duty Kraft Bags | 10-20 | Ideal for retail and groceries |
| Medium-Duty Kraft Bags | 20-50 | Suitable for bulk grains |
| Heavy-Duty Kraft Bags | 50-100 | Designed for industrial goods |
