Frequently Asked Questions
Can ESD Bags Be Reused Safely for Multiple Shipments?
You can reuse ESD bags but should carefully inspect them for damage before each use. It's risky, as worn bags won't provide adequate protection. For critical components, you're better off using new bags.
What Temperature Range Can Standard ESD Static Shielding Bags Withstand?
You can safely use ESD static shielding bags between room temperature and their heat sealing max of 375°F (190°C). For best protection and longevity, you'll want to store them at 76°F (24°C).
How Long Does the Static Shielding Effectiveness Last in Storage?
Your static shielding bags can last up to 20 years if you store them properly. You'll get the best results by keeping them in controlled temperatures and humidity levels, with regular testing for effectiveness.
Are ESD Bags Recyclable Through Standard Recycling Programs?
You can't recycle most ESD bags through standard programs due to their metal layers and special coatings. You'll need to use specialized electronics recycling services or check with local recyclers for specific requirements.
Do ESD Bags Provide Protection Against X-Ray Scanning During Shipping?
No, your ESD bags won't protect against X-ray scanning. They're specifically designed to shield against electrostatic discharge and electromagnetic interference. You'll need additional protection if X-ray exposure is a concern during shipping.
