Understanding Anti-Static Poly Bags

What They Are and When to Use Them 

In environments where static electricity can damage sensitive electronics or disrupt cleanroom settings, anti-static poly bags are essential. These bags are specially formulated to safely dissipate static charges and protect the items they carry. 

This post will explain what anti-static bags are, how they’re made, and the types of industries that rely on them. 

What Are Anti-Static Bags?

Anti-static bags are polyethylene bags blended with an additive that reduces surface resistivity and helps prevent static discharge. While standard LDPE can build and hold a static charge, anti-static bags offer a controlled path for electricity to dissipate. 

These bags are typically pink-tinted to signal their static protection features, but they do not shield against electromagnetic interference (EMI) unless paired with other materials. They are meant for dry, non-hazardous, static-sensitive environments.

How They’re Made

At M Plastics, anti-static bags are produced during the blown film process using a resin blend that includes anti-static agents. These agents are carefully mixed into the melt and dispersed throughout the film to ensure consistent performance. 

We then convert the film into bags using: 

• Layflat cutting for small or medium items 

• Wicketing if high-speed automation is needed 

• Optional printing for warnings, instructions, or branding 

• Customers can inquire about our available formats and minimum run requirements based on their specific needs.  

Common Uses for Anti-Static Bags

Anti-static bags are ideal for: 

• Circuit boards and electronic components 

• Assembly lines for electronics 

• Packaging computer hardware or cables 

• Cleanroom material handling 

• Static-sensitive plastic parts 

• Even small static charges (as low as 100 volts) can damage microchips or sensors — so prevention is critical.   

What They’re Not

It’s important to note that anti-static bags are not the same as static shielding bags. Anti-static film dissipates charges but does not block static from external sources. For high-sensitivity components like CPUs or memory chips, metal-in or metal-out static shielding is more appropriate — but that’s a different product class.

Final Thoughts

If you're shipping or storing components where static charge is a concern, anti-static poly bags offer an affordable and reliable solution. As a blown film manufacturer, M Plastics provides consistent, high-quality film and converting options to match your packaging setup — whether manual or automated.
