Why does vacuum packaging lose its seal

Why Do Vacuum Packaging Bags Leak After Storage?
Customers sometimes discover their vacuum-sealed bags have leaked air after a period of storage. The main causes for this are:

1. Physical Damage from Transportation or Handling:
Impact, abrasion, or poor handling during shipping can puncture or weaken the bag material, leading to leaks. It is crucial to protect the bags adequately during transit to prevent such damage.

2. Substandard Bag Quality (Manufacturing Defects):
This is a critical factor. Leaks often originate from:

• Inadequate Heat Seals: Imperfect sealing during production creates weak points that can fail over time.

• Poor Material Quality: Low-grade or inconsistent film can develop micro-tears or fail to maintain a barrier, allowing air permeation or rupture.

3. Operator Error During Evacuation:
Applying excessive vacuum force can over-stress the bag material, causing it to stretch thin, tear at seams, or puncture on sharp product edges from within. Proper equipment settings and technique are essential.
