Seal Top Pink Anti-Static Bags for Electronics Protection

A seal top pink anti-static bag is a reclosable polyethylene bag tinted pink and treated to a surface resistivity of 10¹² ohms per square inch so it dissipates static charge instead of letting it build up on the bag surface. The press-to-close seal top lets you open and reseal the bag without a heat sealer, and the pink tint is transparent enough to identify contents without opening the package. The polyethylene is amine-free, so it will not outgas onto sensitive components.

Pink bags dissipate static (10¹² ohms per square inch surface resistivity) but are not shielding, while silver metallized bags add a Faraday cage layer that blocks external ESD events and EMI. Use pink seal top bags for general component storage, transport, and in-house handling; use silver shielding bags for extremely sensitive ICs or when RF shielding is required. Pink bags cost less and let you see the contents, which is why they are the everyday choice on most electronics benches.

Yes — these bags measure 10¹² ohms per square inch surface resistivity, which falls inside the static-dissipative range of 10⁹ to 10¹² ohms defined by ESD standards. They are also amine-free, so they will not leave a residue or outgas contaminants onto boards and connectors. They are static-dissipative packaging, not shielding packaging, so they are not a substitute for a metallized shielding bag where full Faraday protection is specified.

Yes. The seal top closure opens and recloses many times without losing its ESD properties, because the static-dissipative treatment is part of the film rather than a coating that wears off at the seal. That makes these bags a good fit for parts that get pulled for testing, inspection, or kitting and then put back into storage. Replace a bag if the closure track is damaged or the film is torn.

Press the two closure tracks together with your fingers and run them from one side of the bag to the other until the seal snaps shut — no heat sealer, tape, or impulse sealer is needed. This is the main workflow advantage over open-top anti-static bags, which have to be heat sealed to close. Squeeze excess air out before sealing if the bag is going into a carton, so it packs flat.

Electronics manufacturers, repair shops, and distributors use them for circuit boards, motherboards, and electronic assemblies; semiconductor handlers use them for ICs and chips; IT and data-center operations use them for hard drives, SSDs, and memory modules. They are also used for medical electronics such as sensors and diagnostic equipment, and for aerospace avionics and precision instruments. Anywhere a component can be damaged by static during storage or shipping is a fit.

No — these bags are made for electronics protection, not food packaging. The polyethylene meets FDA requirements for indirect food contact, but the bags are not intended or merchandised as food packaging and the pink anti-static additive has no place in a food application. For food use, choose a bag from our food service and reclosable food bag categories instead.
