Understanding Amines and Antistatic Packaging

When it comes to protecting sensitive electronics, antistatic packaging is a high-quality solution. But, is it truly amine-free? The short answer: not always. In this blog, we’re breaking down how antistatic packaging works, the potential drawbacks of amine-based packaging, and what alternatives are available if you’re aiming for an amine-free solution.

What is Antistatic Packaging?

Antistatic packaging, also known as electrostatic discharge (ESD) packaging, is designed to prevent electrostatic discharges from damaging products. ESD is the rapid, spontaneous transfer of electrostatic charge induced by a high electrostatic field. While harmless to humans, it can wreak major havoc on electronic components.

According to the ESD Association, “the cost of damaged devices ranges from only a few cents for a simple diode to thousands of dollars for complex integrated circuits. When the associated costs of repair and rework, shipping, labor, and overhead are included, the opportunities exist for significant improvements.” Damages might include:

  • Degradation or destruction of items like semiconductors
  • Disruption to the normal operation of an electronic system
  • Contamination of products, as charged surfaces can attract and hold onto contaminants
  • And more

That’s why antistatic packaging is so important. It helps protect electronic devices, saving businesses money in the long run. However, it’s important to note that there are two different types of antistatic bags. Choosing the right one is imperative to long-term success.

Dissipative bags are made of polyethylene with a dissipative coating. They prevent static buildup by dissipating the charge to the ground. These bags are good for general static protection. Static shielding bags provide a Faraday cage effect that shields products from electric energy. These bags protect goods from internal and external static buildup and ESD. They are most commonly used for shipment and storage of ESD-sensitive items.

Why are Amines Used in Packaging?

Antistatic packaging works because of the use of amines. They are primarily used as an antistatic agent to prevent the buildup of static electricity on plastic packaging materials. This helps prevent ESD or other issues like clinging or sticking during packaging.

The two free hydrogen atoms in the ethoxylated fatty amine form an -OH (alcohol) group. This creates a polar group that attracts moisture from the air, turning it into water (H2O). Since water is conductive, it makes the bag’s surface antistatic — provided the bag is grounded. Essentially, the polar nature of amines allows them to attract moisture from the air, creating a conductive surface that dissipates static charges.

Is Antistatic Packaging Amine Free?

Antistatic packaging usually relies on amines for protection against ESD. They are usually safe in most kinds of packaging. However, there are some risks to keep in mind.

  • Some quaternary ammonium salts in antistats can corrode silver solder contacts on circuit boards and electronics.
  • Some amines like primary aromatic amines (PAAs) can be a concern in food packaging. In these cases, the amines may migrate to the food product, which can cause concerns regarding potential toxicity.
  • Higher humidity and better antistat bloom improve performance. But, this can cause the antistatic layer to feel greasy, which some customers mistake for contamination.

In conclusion, most antistatic packaging will rely on amines. However, there are other options available if you’re looking for an amine-free solution. You can choose a carbon black bag with no amines or specify the use of a non-amine antistat additive in polyethylene.
