How to Store PP Woven Bags: 4 Rules to Prevent Damage

We often see a sad scenario: A client buys high-quality bags, stores them incorrectly for 6 months, and then complains that the bags are "tearing easily."

Here is the truth: Polypropylene (PP) is a plastic polymer. Like all plastics, it reacts to the environment. If you treat your inventory well, it will last for years. If you neglect it, it can degrade in weeks.

1. The "Vampire Rule" (Avoid Sunlight)

Polypropylene hates UV radiation. Sunlight breaks down the chemical bonds in the plastic fabric, making it brittle and weak (chalking).

Action Step: Never store bags in an open yard, even for "just one day." Keep them inside a shaded godown. If you have skylights or windows in your warehouse, cover the bag stacks with a dark, opaque tarpaulin to block indirect light.

2. Elevation is Mandatory

Concrete floors release moisture, especially during the monsoon season. This dampness seeps into the bottom layer of your bag stack, causing fungus, bad odors, and fabric weakness.

3. Follow the FIFO Method

Plastic has a shelf life. The bags you bought in January should be used before the bags you bought in March.

Implement the First-In, First-Out (FIFO) system in your warehouse. Train your staff to always pick stock from the "Oldest Pile" first. This ensures no bundle sits at the back of the warehouse for years, slowly degrading.

4. Proper Handling (The "No Hooks" Policy)

The most common cause of damage happens right when you open the bundle. Using sharp iron hooks to drag bundles creates micro-tears in the fabric.

Summary Checklist for Your Store Manager

Print this out and stick it in your godown:

• ✅ Is the area dry and cool?
• ✅ Are windows covered?
• ✅ Is the stock on pallets?
• ✅ Is the area free from rodents/rats?
