Custom Designs for Specific Applications
The adaptability of Sewn Open Mouth sacks stems from their ability to incorporate specialized features. Depending on the intended use, these bags can offer tailored solutions, such as breathability, barrier protection, anti-static properties, and antimicrobial materials.
1. Breathability for Agricultural Products
For products like grains, rice, and vegetables, breathability is essential to prevent moisture build-up and heat accumulation. SOM Bags with perforated or ventilated designs allow air circulation, which is critical for maintaining freshness.
Advantages:
- Prevents spoilage by allowing heat and moisture to escape.
- Reduces risk of fungal growth in humid environments.
Example Application: Grain exporters often utilize Bottom Open Mouth Bags with ventilated panels to ensure quality during long shipments.
2. Barrier Designs for Sensitive Materials
Certain products require protection from external factors like moisture, gas, and odor. Laminated Open Mouth Bags can incorporate barrier layers made of specialized materials, offering superior resistance.
| Barrier Feature | Benefit |
|---|---|
| Gas Barrier | Prevents contamination of chemical substances. |
| Moisture Resistance | Ideal for products like cement and powdered food ingredients. |
| Odor Protection | Keeps food products fresh by minimizing odor exchange. |
