This post explains the process for correctly installing polyethylene liners in bulk bags to protect goods. Proper installation involves preparing the bag and liner, careful insertion, and monitoring during filling for maximum protection.
- Prepare bag and liner
- Insert liner carefully
- Monitor liner during filling
- Creates effective cargo barrier
Using polyethylene liners inside bulk bags is the perfect way to guard your bulk goods against moisture, dust, pests and contamination. If you want your sensitive goods kept clean and dry, a high-quality polyethylene liner from Tufbag will help you maintain the integrity of your cargo from loading to unloading.
Let’s take a look at how installing a polyethylene liner works and the difference it can make when you fill and store your bulk bags.
How To Prepare For Liner Installation
Preparing your liner for installation is easy if you follow these steps:
- Spread the bulk bag out on a clean and dry floor or pallet.
- Check that the interior seams and folds are flat and clear to avoid damaging the liner.
- Unfold the liner gently and inspect it for any tears or weak spots.
- Confirm that the liner’s size and shape match the bulk bag before starting the insertion process.
How Should You Insert The Liner Into The Bag?
Once the liner is prepped, here’s how to settle the liner into place inside the bulk bag:
- Slide the liner carefully into the bag and align its corners and walls with the bag’s shape.
- Push the liner downward until it sits evenly against the inner walls.
- Smooth out wrinkles or air pockets so the liner fits snugly.
- Ensure the liner is stable and properly conforms to the bag before filling.
What To Watch For While Filling
Filling can be done with manual scooping or mechanical loading. Monitor the liner’s top edge during filling to keep it open and correctly positioned so it doesn’t fold, tear or trap material.
If your liner has a fill spout or drawstring, close or tie it before sealing the bulk bag top. That closure will limit leakages and prevent dust from escaping through the seams, which is a common problem when no liner is used.
