Vacuum sealing otherwise know as dry packaging is the process of removing oxygen from a bag with the goal of extending the shelf life and preserving the material or product inside the bag. In electronics and industrial packaging, vacuum sealing is essential for sensitive materials, especially when used with anti-static bags and moisture barrier bags.
A proper anti-static bag vacuum sealer helps eliminate moisture and electrostatic risk during storage or transit.
Industrial vacuum sealers are available in a variety of sizes and styles with features that can accommodate most any sealing application.
Why Use an Anti-Static Bag Vacuum Sealer?
When packaging circuit boards, semiconductors, or other static-sensitive devices, a vacuum sealer for anti-static bags ensures a controlled, ESD-safe environment. These sealers remove air and moisture while preserving the anti-static and barrier properties of specialized packaging materials.
Correct Products offers a wide range of vacuum sealers compatible with anti-static and moisture barrier bags used in cleanrooms, electronics manufacturing, aerospace, and medical applications.
How to Vacuum Seal Anti-Static or Moisture Barrier Bags
Most ESD moisture barrier bags are vacuum-sealed using nozzle (or snorkel) vacuum sealers. Here’s the step-by-step process:
-
Position the Bag
Place the open edge of the ESD bag over the seal bar. Insert the nozzle or snorkel inside the bag. -
Start the Vacuum Process
Press the foot pedal or start button to close the seal bars and begin air extraction. -
Air Evacuation
As the nozzle removes air, the bag conforms tightly around the product. -
Seal and Cool
After evacuation, heating elements seal the bag. The system enters a dwell/cool cycle to ensure a tight seal. -
Complete the Process
The seal bars open, and the sealed anti-static bag is ready for handling or shipment.
Vacuum Sealer Options for Anti-Static Bags
When selecting a vacuum sealer for use with anti-static or shielding bags, consider these optional features:
✅ Self-Contained Vacuum Sealers
Ideal for mobile or remote workspaces. These sealers include an internal compressor — no external air supply needed.
✅ Gas Purge Option
Injects nitrogen or another inert gas into the bag before sealing, removing all oxygen. Recommended for long-term storage of sensitive electronics.
✅ Dual Nozzle Systems
Two nozzles allow faster evacuation, ideal for large moisture barrier bags.
✅ Vacuum Filter
Prevents powders or liquids from contaminating your sealer — essential for cleanroom or lab use.
✅ Vacuum Regulator
Controls vacuum pressure to prevent crushing delicate items.
✅ Dual Heating Elements
Top and bottom heat bars create strong, uniform seals for thick foil bags.
Choosing the Right Moisture Barrier or ESD Bag
When using a vacuum sealer for anti-static bags, it’s important to choose the right packaging materials. Consider:
-
MVTR (Moisture Vapor Transmission Rate) – Lower MVTR = better moisture resistance.
-
Bag Thickness – Thicker = more puncture-resistant.
-
Material Type:
-
ESD Moisture Barrier Bags: Multi-layer protection, ideal for vacuum sealing.
-
Mil-Spec Bags: Compliant with government and aerospace standards.
-
Clear Poly/Nylon Bags: For general commercial use (not for ESD-sensitive items).
-
⚠️ Not all anti-static bags are vacuum-sealable. Only metallized shielding or moisture barrier bags should be used. Pink static-dissipative bags are for open-air use only.
Frequently Asked Questions
Can I vacuum seal anti-static bags?
Yes — as long as you’re using metallized shielding or moisture barrier bags. Pink bags are not suitable for vacuum sealing.
What type of vacuum sealer works with anti-static bags?
Use a nozzle-style vacuum sealer with adjustable heat and vacuum control, compatible with foil-lined materials.
Why vacuum seal electronics?
To protect against ESD, moisture, and contamination — especially during long-term storage or shipping.
