What is anti-static bags? How does it work? Where is the factory?

1.What is anti-static bags?

Anti-static bags are the most popular plastic packaging in factory of the electronic components and devices.

This is one of the necessary supplies contribute to protection process of production and application.

2.How anti-static bags work?

Active friction will generate electrical charges, which will adhere to the nearest materials. They will wait until another object of opposite charge approaches; they will discharge into each other and neutralize and cause an explosion effect.

Electronic components are extremely sensitive products, even a very small discharge can cause these components to explode and damage.

ESD anti-static bags are the best choice for electronic components packaging. The anti-static ability of the bag helps prevent the formation of internal static electricity. And isolate the products inside from the external electrostatic field; Protecting the product from potential electrostatic damage; ESD bags can also resist electrical interference.

ESD bags usually have a resistance in the range of 10^6 – 10^11, depending on the demand of the customer.

Not only anti-static function, but the ESD anti-static bag can also be a shielding of the electrostatic discharge and electrical waves from external devices .

In addition, using a vacuum bag that prevents the device inside from being exposed to the outside air, is waterproof, moisture-proof and does not oxidize.

3.Anti-static Classification

3.1. Anti-static Shielding Bag

Anti-static Shielding Bag is transparent/translucent, silver gray.

We can see the products inside very easy.

This shielding bag is made up from at least 2 single layers film. VMPET is the semi-metallized PET film which cover a very thin of metal. It will be laminated with PE or CPP sometimes for making bags.

Depend on customer requirement, the bags may be combined of 2,3 or 4 layers to enhence its characteristics. Such as moisture barrier, durable, flexibel,….

3.2. Anti-static MBB Moisture Barrier Bag

There are 2 types of MBB Moisture Barrier Bag that customer normally confusing:

– Anti-static High Moisture Barrier Bag:

Or also called Anti-static aluminum bag.

It usually have 3 basic layers including aluminum foil film at the middle. It’s opaque.

This foil helps preventing oxidation and can maximize the ability to prevent light and moisture.

Aluminum bags are the most optimal moisture- and light-blocking bags among electronic components bags.

Aluminum bags can also be laminated with more than 3 layers depending on the needs of customers.

– Anti-static Moisture Barrier Bag:

Or also called Anti-static metallized bag.

This bag includes 2 base layers metallized film MPET and PE film.

The MPET film is high metallized coated film, opaque, which helps to prevent light.

Metallized bags have better moisture and light preventing properties than shielding bags. The bag has a silver color and high gloss aesthetic.

The bag can be laminated with more than 2 layers depending on the needs of the customer.

The water vapor transmition rate of both Anti-static High Moisture Barrier Bag and Anti-static Moisture Barrier Bag reach <0.005 g/(m2.24h)

3.3. Anti-static Transparent Nylon Bags

Anti-static Transparent Nylon Bag have at least 2 single layer film. It may be lamination of PA,PET,OPP with PE or CPP

Because of its transparent, the products can be see clearly.

Anti-static Transparent Nylon Bag also adjust 3,4 or more single layer films, depending on requirements.

PA or Nylon – Polyamide film is the most durable and high moisture barrier, PA/PE lamiantion is the most reasonalble material for vacuum and long storage.

The water vapor transmition rate of PA/PE bags produced by Proline reaches <0.005 g/(m2.24h)

3.4. Anti-static PE bag

Different from the above bags which are multi-layer composite bags, anti-static PE bag have only 1 layer of PE film, which can be transparent or slightly translucent.

Anti-static PE bag are usually applied to large electronic products, which need large-sized packaging bags.

3.5. Anti-Static Zipper Bag

Anti-static zipper bag is a bag with 3 sealing side seam with a zipper open top so that the user can close it after use/inspection.

The bag can be reused many times and can be closed without the use of a heat sealer.

With this convenience, the anti-static zipper bag also has the risk and disadvantage of not being sealed when the bag is sealed.
