Ordinary Plastic Bags vs ESD Poly Bag
Electrostatic discharge (ESD) is one of the leading causes of component failure in electronics manufacturing.Conventional plastic bags generate thousands of volts of static electricity during friction and opening, directly endangering delicate electronic products.ESD poly bags provide reliable protection for sensitive components through static dissipation or shielding.

FQA
Q: What is the difference between ESD poly bags and ordinary PE bags?
A: Ordinary PE bags have surface resistivity above 10¹² Ω, making them insulative. They can generate over 2000V of static electricity, risking component breakdown.ESD poly bags use antistatic additives to control surface resistivity between 10⁹–10¹¹ Ω, allowing rapid static dissipation and protecting delicate electronics.
Q: When should I use flat bags, zip bags, or grip-seal bags?
A: Flat bags: Ideal for one-time sealed packaging; cost-effective and secure for high-volume production. Zip bags (reclosable): Reusable, suitable for frequent access, sample storage, and warehouse logistics. Grip-seal bags: Wider, stronger closure for heavier items and improved moisture/dust protection.Our team can recommend the best style based on your usage and packaging frequency.
Q: What is the difference between pink and transparent ESD bags?
A: Pink is the industry standard color for easy visual identification of ESD packaging in production and storage, preventing accidental use of non-protective bags.Transparent ESD bags offer higher clarity for scanning, inspection, and product display.Both provide identical antistatic performance; choose based on your operational requirements.
Q: How do I verify antistatic performance?
A: Use a surface resistance meter to test both inner and outer surfaces. Standard dissipative ESD bags should measure 10⁹–10¹¹ Ω.We provide factory inspection reports for every batch and can arrange third-party certification (e.g., SGS) upon request.
Q: Can ESD poly bags directly contact PCBs or IC chips?
A: Yes. Our bags use food-grade PE and antistatic masterbatch with no migratory or corrosive substances, making them safe for direct contact with PCBs, ICs, and precision electronics. For enhanced protection, we recommend the 10⁹ Ω grade paired with ESD trays.
Q: How durable is the zip closure? Does repeated opening affect antistatic performance?
A: Our high-quality zippers withstand over 500 openings and closures without breaking or loosening.Antistatic performance comes from the film itself, not the closure, so repeated use does not reduce static protection.
Q: Does antistatic performance degrade over time?
A: No. Antistatic additives are uniformly dispersed throughout the film, not sprayed on the surface. Performance does not fade over time, wiping, or friction. Under normal storage conditions, antistatic properties last more than 5 years.
Q: Can you print ESD warning logos? Does printing affect performance?
A: Yes, we support ESD symbols, LOGOs, product text, and barcodes using 7 color rotogravure and eco-friendly inks. Printing is applied to the surface and does not compromise the film's antistatic properties.
Q: Can you supply food-grade ESD poly bags?
A: Yes. We use food-grade PE resin and food-contact compliant antistatic masterbatch for medical electronics, food-related applications, and can provide corresponding food-grade test reports.
Q: What is your minimum order quantity? Do you offer samples?
A: Standard MOQ is 1 metric ton; small trial orders (e.g., several thousand pieces) are negotiable.Samples are available in 1–3 days, free of charge, with freight collect. Custom printed samples require confirmation of plate fees.
