- What causes the bags to look like they are vacuumed packed?
- This is a function of the valve on the bag. The valve is a one way valve designed to let air out but not in. Our bags are stacked on pallets for distribution and bags closer to bottom of the pallet release more air due to the weight of the bags on top of them. Changes in temperature and atmospheric pressure will also cause a change to the air in the bag which can cause air to build up in the bag and once released it create a natural vacuum.
