Why Use Pink Anti-Static Bags?
Pink anti-static bags protect sensitive electronic components from electrostatic discharge (ESD) during packaging, storage, and shipping. The pink color makes them instantly recognizable as ESD-safe packaging, reducing handling errors.
Key Features of LK Static Control Bags:
- 10¹² Ohms Surface Resistivity: Anti-static film that resists triboelectric charge buildup (anti-static, not shielding)
- Pink Anti-Static Material: Polyethylene with anti-static additives
- Amine-Free Formulation: Safe for polycarbonate circuit boards (no corrosion)
- Heat Sealable: Create tamper-evident closures with impulse or heat sealers
- Bright Pink Color: Easy identification in warehouse and shipping areas
- Multiple Sizes: Stock sizes for PCBs, components, and electronics
What Do Pink Anti-Static Bags Protect?
- Printed Circuit Boards (PCBs): Motherboards, logic boards, control boards
- Electronic Components: ICs, chips, semiconductors, transistors, capacitors
- Computer Parts: RAM, hard drives, SSDs, graphics cards, network cards
- Sensors & Instrumentation: Measurement devices, MEMS devices
- Medical Electronics: Diagnostic equipment, patient monitors, control modules
- Aerospace & Defense: Avionics, navigation systems, communication equipment
Pink Anti-Static vs Other ESD Bags
| Bag Type | Surface Resistivity | Protection Level | Best For |
|---|
| Pink Anti-Static | 10¹² ohms | Anti-static — resists charge buildup, no shielding | PCBs, components (moderate ESD sensitivity) |
| Metallized / StratoGrey Shielding Bags | Multi-layer | Faraday cage — blocks outside ESD | High-sensitivity ICs, military/aerospace |
| Standard Poly Bags | 10¹⁴+ ohms | No ESD protection | Non-electronic products only |
Understanding ESD Protection Levels
When to Use Pink Anti-Static Bags:
- Most printed circuit boards (PCBs)
- Standard electronic components
- Computer parts (RAM, drives, cards)
- Internal warehouse handling and storage
- Assembly line work-in-progress
When to Upgrade to Static Shielding Bags:
- Highly sensitive ICs (microprocessors, FPGAs)
- Long-term storage (over 6 months)
- Shipping to high-static environments
- Military/aerospace applications with MIL-SPEC packaging requirements
- Any spec that calls for Faraday cage protection — see StratoGrey Static Shielding Bags
Why Amine-Free Matters
Amine-based anti-static additives can attack polycarbonate materials commonly used in circuit boards and component housings. Our LK Static Control Bags use amine-free formulations to ensure your boards remain safe during storage and shipping — no chemical damage, no component degradation.
How to Use Anti-Static Bags
- Ground Yourself: Wear an ESD wrist strap before handling components
- Insert Component: Place electronics in the bag on an anti-static work surface
- Seal Bag: Heat seal (impulse sealer) or tape shut (ESD-safe tape recommended)
- Label: Mark the bag with component ID, date, and handling instructions
- Store Properly: Keep in a dry, temperature-controlled environment (avoid extreme heat)
Frequently Asked Questions
What is a pink anti-static bag?A pink anti-static bag is a low-density polyethylene bag treated with anti-static additives so the film itself does not generate a static charge when it is handled, rubbed, or opened. It is used as the immediate packaging around circuit boards, chips, and other ESD-sensitive electronics. The pink tint is a visual code — it tells anyone on the line that the bag is ESD packaging and the contents need static precautions. What does 10¹² ohms surface resistivity mean?Surface resistivity measures how readily a static charge moves across the surface of the film, and 10¹² ohms per square inch is the rating for LK pink anti-static film. That is far more conductive than an untreated poly bag (10¹⁴ ohms and up), which is what keeps the bag from building and holding a charge against your parts. It is an anti-static rating, not a shielding rating — the bag will not stop a static field originating outside it. What is the difference between anti-static bags and static shielding bags?Anti-static bags stop the bag itself from generating a charge, while static shielding bags add a metallized or dual-coated layer that forms a Faraday cage and blocks static discharge from outside the bag. Pink anti-static is the right choice for in-house handling, work-in-progress, and shipping standard components. If your part spec calls for shielding, or you are shipping highly sensitive ICs, step up to StratoGrey Static Shielding Bags. What size anti-static bag do I need?Measure the length and width of the board or component at its widest points, then add about 1" to the width and 2" to the length so the part slides in without scraping and you have room for a heat seal. For a standard ATX motherboard (roughly 12" x 9.6") that puts you around an 11" x 14" bag. If the item has depth to it — a boxed drive or a stacked assembly — add the thickness to the width measurement as well. Can I heat seal pink anti-static bags?Yes — LK Static Control Bags are polyethylene and seal cleanly on an impulse sealer or constant-heat sealer. Heat sealing gives you a tamper-evident closure that is ideal for shipping and long-term storage. If you need the bag reopened later, fold the top over and close it with ESD-safe tape instead. Why are anti-static bags pink instead of clear?The pink tint is a deliberate industry convention that flags the bag as ESD packaging at a glance. It prevents the most common warehouse mistake — someone grabbing an ordinary clear poly bag for a static-sensitive part, or pulling a board out of an ESD bag without grounding first. The color has no effect on the anti-static performance; that comes from the additive in the film. Do pink anti-static bags block moisture?No — pink anti-static bags are a static-control film only and offer no meaningful moisture barrier. Polyethylene slows liquid water but does not stop water vapor, so humidity will reach the contents over time. For moisture-sensitive devices (MSL-rated components, long-term storage, humid warehouses), use a foil moisture-barrier bag with desiccant rather than relying on the pink bag. Can I use pink anti-static bags for long-term storage?They are fine for moderate-sensitivity components stored under about six months in a controlled, dry environment. Beyond that, two things work against you: there is no moisture barrier, and the bag offers no shielding against static fields the parts may sit near for months. For longer holds or higher-value assemblies, move to a shielding bag, and add desiccant if humidity is a factor. Are pink anti-static bags reusable?Yes, as long as the bag is undamaged — no punctures, tears, or heavy creasing — and it has not been heat sealed, since sealing is a one-time closure. Anti-static performance does depend on the additive in the film, so bags that have been in service a long time or stored in extreme heat are worth retesting with a surface resistance meter before reuse. For critical or customer-facing parts, most shops use fresh bags and reserve the used ones for internal WIP. Can I write on a pink anti-static bag?Yes — a permanent marker writes on the pink film without any surface prep, and pressure-sensitive labels stick well to it. Label the exterior with part number, revision, date, and any handling instructions before the bag goes into stock. Write on the bag before you insert the component so you are not pressing a pen against the board. Are pink anti-static bags recyclable?They are low-density polyethylene (resin #4), so they are not accepted in curbside recycling, and many store film drop-off programs will not take them either because the anti-static additive and pink colorant contaminate the clear film stream. Check with your waste hauler before assuming they can go in a film bale. There are no hazardous-waste concerns with the amine-free formulation — the limitation is stream contamination, not toxicity. Compliance & Standards
- Surface Resistivity: 10¹² ohms/sq.in. — an anti-static film rating, not a static shielding rating
- Amine-Free: Safe for polycarbonate circuit boards and housings
- Material: Low-density polyethylene (LDPE) with anti-static additives
- Use in ESD Programs: Commonly specified as intimate packaging within ANSI/ESD S20.20 control programs; where a spec calls for a Faraday cage, a shielding bag is required instead
