Many people ask "are mylar bags anti static?" The answer to this question will depend on what type of Mylar bag you have and how it was produced.

No, standard Mylar bags are not designed anti static. However, specialized Mylar bags can indeed be designed to be anti static. By using static dissipative coatings or treated materials, this makes the mylar anti static and suitable for electronics and other static sensitive products.

Mylar bags are used across various industries including electronics, hemp packaging, food storage and industrial uses due to their strength and their ability to provide high barrier protection from the elements.

What Is Mylar and How Does Static Build Up?

Mylar is a name for a type of polyester film known as PET. Like many plastic products, standard Mylar develops static electricity through friction, dry air, and movement of the Mylar material against itself or other materials. Because of these factors, normal Mylar bags are not anti static and they can generate or carry an electrical charge when exposed to such conditions.

As a result, static electricity may be a significant risk when packing electronics, electronic parts, or finely powdered materials that may adhere to the lining of the bag.

Are Standard Mylar Bags Anti Static?

Standard Mylar bags are not inherently designed to be anti-static. Most common uses of Mylar for food storage or consumer packaging does not have any type of static dissipative treatment. They are great at keeping moisture, oxygen and light out, but they are not designed for preventing static charge accumulation unless specified.

For non-static sensitive applications (e.g., food, coffee, supplements, hemp flower) standard Mylar bags are more than adequate.

What Are Anti Static Mylar Bags?

Mylar bags designed for use as anti static are specifically created with special anti static coatings and layers that control or dissipate static electricity from the contents of these bags. Anti-static Mylar bags are typically used to package electronics, and they may contain:

1. Static dissipative coatings
2. Metallized layers designed for electrostatic discharge protection
3. Carbon infused or treated films

Most Mylar bags that are designated as an anti static or ESD protective, are labelled as such, and are manufactured to meet specific industry's requirements.

While anti static Mylar bags are typically used for electronics, standard Mylar bags are more commonly used for food storage, cannabis packaging, and other applications, which we cover in detail in our guide on what Mylar bags are used for.

When Do You Need Anti Static Mylar Bags?

When packing one of the following, you should consider using some type of anti-static mylar packaging:

• Electronic parts, including printed circuit boards
• Sensitive computer chips / microchips
• Powders that generate static electricity

For consumer packaged goods, most manufacturers do not require any type of static protection due to the lack of benefit provided by the expense.

Can Customized Mylar Bags Be Anti-Static?

Yes, customized Mylar bags can be manufactured with static inhibiting capabilities, if the customer needs this feature. This will be achieved by using packaging films and/or coatings that have anti-static characteristics in the construction of your Mylar bag. Typically, this is for electronics-based industries rather than for retailing products such as food and snacks.

If static control is a significant factor for your product, it is essential to ask for anti-static or ESD safe materials during the design and quoting processes.

So, Are Mylar Bags Anti Static?

Standard Mylar bags are not designed to be anti static and can generate static electricity due to their PET plastic construction. However, Mylar bags can indeed be manufactured with anti static or ESD safe materials when needed, allowing them to safely dissipate static for electronics or sensitive applications.

Typically, they are not designed to be anti-static because PET plastic has a natural propensity to generate static electricity. That being said there are Mylar bags that are manufactured specifically for consumer electronics which are be made anti-static. With regards to the majority of food and general consumer goods, the purchase of standard Mylar bags should be enough.
