The Role of Open Mouth PP Bags in Material Protection
Key Features and Applications
- Material Durability: PP (polypropylene) woven construction ensures resistance to tearing and punctures during transit and storage.
- Moisture Resistance: Laminated finishes and integrated liners protect against water damage.
- Customizability: Tailored designs, including valve options and multi-color printing, meet specific industry demands.
- Leak Prevention: These bags prevent leakage of powders and granular materials, ensuring product integrity.
Importance in Construction Materials
- Cement: Prevents hydration or contamination during transport.
- Gravel and Sand: Durable enough to handle heavy weights.
- Putty Powder and Gypsum: Ensures fine powders are secure, avoiding spills or loss during handling.
Standards and Specifications for Open Mouth PP Bags
Understanding global standards helps in selecting the right bag for specific needs. Here’s a comparison of key specifications across regions:
| Standard | Requirement | Key Features |
|---|---|---|
| EN (Europe) | High tensile strength; UV resistance | Meets EU environmental directives. |
| ASTM (USA) | Moisture barrier; high load capacity | Suitable for harsh handling. |
| JIS (Japan) | Anti-leak design; precision measurements | Emphasis on uniformity. |
| AS (Australia) | Weather-resistant; eco-friendly | Adapted for outdoor conditions. |
Parameter Selection for Optimal Bag Performance
When choosing an Open Mouth Bag, critical parameters include:
Material and Weight
- Weight: Higher GSM (grams per square meter) ensures strength.
- Material Composition: Options include virgin polypropylene for premium durability.
Size and Capacity
- Ranges from 5 kg to 50 kg for typical uses, with customization available for larger loads.
Laminations and Liners
- Laminations protect against moisture ingress.
- Inner liners add an extra barrier for powders like putty and gypsum.
| Parameter | Value Ranges | Purpose |
|---|---|---|
| Bag Weight | 60-120 GSM | Durability for heavy materials. |
| Load Capacity | 5-50 kg | Varies by material type. |
| Coating Thickness | 20-30 microns | Waterproofing and wear resistance. |
| Sealing Type | Sewn, heat-sealed | Prevents leaks; ensures closure. |
