Here is the English translation for Ventilated (Vented) Big Bags:
What is a Ventilated Big Bag?
A Ventilated Big Bag (also known as a Vented or Breathable Big Bag) is a type of packaging featuring vertical air vents integrated into the body fabric through specialized weaving techniques.
While standard Big Bags are essentially airtight, ventilated models allow continuous fresh air circulation and enable internal moisture to escape.
Why Use Ventilated Big Bags?
Certain products are "living" and continue to respire even after harvest. If these products are placed in airtight containers:
Moisture Accumulates: The product becomes wet from its own condensation.
Mold and Rot: Bacterial growth accelerates rapidly.
Overheating: Without air circulation, the internal temperature rises, causing the product to "cook" or spoil.
Key Features
Air Vents: Vertical gaps left in the fabric weave (typically 13 to 26 ventilation strips per bag).
Durability: Despite the air channels, the fabric is made from high-strength polypropylene to carry loads of 1,000–1,500 kg.
UV Protection: Treated with UV additives to prevent the plastic from degrading when exposed to sunlight.
Discharge Spout: Usually designed with an opening/closing spout at the bottom to facilitate fast unloading.
Common Applications
Which products require a ventilated big bag?
| Product Group | Why Ventilated? |
| Potatoes & Onions | To prevent rotting and sprouting. |
| Carrots & Turnips | To maintain moisture balance and extend freshness. |
| Firewood & Logs | To allow moisture in the wood to dry and prevent mold. |
| Fresh Nuts | To prevent mold in freshly harvested walnuts or hazelnuts. |
Technical Structure Options
4-Panel Ventilated: Air channels are present on each of the four side surfaces.
U-Panel Ventilated: The main body and side panels feature air channels; this is the most common model.
Conical Bottom: Designed for fluid discharge, ensuring the product flows out without getting stuck.
