Product Overview

What is a silo bag?
A high-performance polyethylene bag, typically 60 meters long and 2.75 meters in diameter, designed for grain storage in open environments. It is ideal for storing wheat (up to 220mt), maize, barley, paddy, mustard, soya, and other essential commodities.
Material Composition:
Constructed from a laminated plastic sheet with 3 layers of co-extruded polyethylene (250 microns thick). The outer layers provide weatherproofing and UV filtration, while the inner black layer protects the grain from sunlight degradation.

Frequently Asked Questions

Q1: What materials are used in the silo bags?
A: Our silo bags are made from 100% virgin LDPE/LLDPE with high-grade UV stabilizers, using a multi-layer co-extrusion process for maximum durability.
Q2: How long can the grain be stored in these bags?
A: With proper sealing and handling, the UV resistance is guaranteed for a minimum of 18 months in outdoor conditions.
Q3: Why are the bags white on one side and black on the other?
A: The white side reflects sunlight to prevent heat buildup, while the black side ensures total opacity to protect the nutrients and quality of the stored feed.
Q4: What capacity do the standard bags have?
A: A standard 60-meter bag can store approximately 220 metric tons of wheat, depending on the grain density and diameter of the bag.
Q5: Can these bags be recycled?
A: Yes, our bags are made from recyclable polyethylene materials, making them an environmentally friendly choice for agricultural storage.
Q6: How do you prevent spoilage in the bag?
A: By following the correct filling and sealing procedures, the bag creates an anaerobic environment that significantly reduces the risk of spoilage and nutrient loss.
