Large Resealable ESD Bags 7.87×11.8″ (20×30 cm) with Anti‑Static Labels

Protect your GPU, hard drive, SSD, and sensitive electronics – with convenient zip lock + labels

When you store or ship high‑value electronics like graphics cards, solid‑state drives, or memory modules, you need more than just static protection – you need a moisture barrier, resealable convenience, and clear identification. ZXCOOL’s large resealable ESD bags combine all three.

Each bag measures 7.87 × 11.8 inches (20 × 30 cm) – a perfect fit for most GPUs, 3.5″ and 2.5″ hard drives, SSDs, RAM sticks, I/O memory cards, earphones, and other electronic devices. The bag is constructed from PET + aluminized film, offering ±500°C temperature tolerance, high‑moisture resistance (Class II), and a reusable zip lock seal. Plus, each bag comes with anti‑static labels for easy content identification.

✅ Included: Anti‑static labels (write‑on or pre‑printed)
✅ Reusable zip seal – no heat sealer needed
✅ Semi‑translucent – see contents without opening
✅ Custom sizes & logo printing available

Why Choose ZXCOOL Resealable ESD Bags?

🔹 Safety & Environmental Protection – PET + Aluminized Film

These bags are manufactured from high‑quality Polyethylene Terephthalate (PET) with an internal aluminized layer. This construction provides:

• Excellent high & low temperature performance – withstands ±500°C (intermittent) without degradation

• Non‑toxic & eco‑friendly – free from heavy metals and hazardous substances

• Static shielding – the aluminized layer acts as a Faraday cage, blocking external electrostatic fields

Unlike ordinary anti‑static bags, this bag protects against both ESD and moisture/vapor – critical for sensitive devices like bare hard drives and PCBs.

🔹 Hold Sealing Belt – Waterproof, Damp‑Proof & Vacuum Compatible

The bag features a high‑performance sealing belt (zip lock) that is:

• Reusable – open and close hundreds of times

• Waterproof & damp‑proof – moisture resistance rated Class II (protects against high humidity and light splashes)

• Vacuum compatible – you can evacuate air to prevent oxidation of electronic components (use a vacuum sealer with a smooth jaw)

For long‑term storage of bare hard drives or GPU circuit boards, vacuum sealing dramatically extends component life.

🔹 Reusable Zip Lock Seal – No Extra Equipment Needed

The reliable resealable zipper ensures a tight closure every time:

• Easy open & seal – press along the track until it clicks

• No heat sealer, no tape – ready to use out of the box

• Economical & convenient – perfect for daily handling in repair shops, labs, and assembly lines

• Long‑term use – zipper withstands repeated cycles without losing seal integrity

Whether you are taking components in and out of storage multiple times a day, or sealing them for a one‑time shipment, this zip lock delivers consistent protection.

🔹 Translucent Design + Anti‑Static Labels Included

Unlike opaque ESD bags that hide contents, our semi‑translucent film lets you:

• Clearly view inside items – quickly identify which GPU or hard drive is inside

• Display products – ideal for display cabinets, retail packaging, or inventory shelves

• Keep out dust & dirt – while still seeing what’s there

Each bag comes with anti‑static labels (write‑on or pre‑printed “ESD sensitive” – specify when ordering). Use them to:

• Mark part numbers, serial numbers, or dates

• Add barcodes or QR codes

• Indicate handling instructions

The labels are made from static‑dissipative material, so they won’t compromise the bag’s ESD performance.

Perfect Fit for Common Electronics

*For larger GPUs (e.g., 10″+ length), please request custom size – we offer any dimension.*

FAQ – Large Resealable ESD Bags with Labels

1. Are these bags truly ESD safe? How do they compare to pink anti‑static bags?
Yes. These bags are static shielding bags – they have an outer conductive layer and an inner aluminized layer that creates a Faraday cage. They offer higher protection than standard pink anti‑static bags (which only dissipate surface charge). Pink bags are fine for general handling; for shipping bare hard drives or GPUs, use static shielding bags like this one.

2. What is the ±500°C temperature rating?
The aluminized PET film can withstand brief exposure to very high or low temperatures (e.g., during soldering, autoclaving, or extreme storage). For continuous use, stay within –50°C to +50°C. The ±500°C rating refers to intermittent peaks – do not use as an oven bag.

3. Can I vacuum seal these bags with a standard home vacuum sealer?
Yes, provided your sealer has a smooth sealing bar (not a wire/impulse type that melts through). Place the open end of the bag across the seal bar, vacuum, then seal. The zip lock remains usable after vacuum sealing.

4. How do I use the included anti‑static labels?
The labels are made from static‑dissipative material. Write on them with a standard pen or marker, then peel and stick onto the bag. They will not generate static charge. For pre‑printed labels (e.g., “ESD SENSITIVE”), specify at order.

5. Are these bags reusable?
Absolutely. The zip lock seal is designed for hundreds of open/close cycles. As long as the bag is not punctured or torn, you can reuse it many times – reducing waste and cost.

6. What does “moisture resistance Class II” mean?
Class II indicates the bag provides protection against high humidity and light water spray (e.g., in a damp warehouse or during shipping in rain). It is NOT submersible – do not place underwater.

7. Can you make larger sizes for full‑size GPUs?
Yes. Many modern GPUs (e.g., RTX 4080, RX 7900 XT) are 12–13″ long. We offer custom sizes like 12×15″ or 14×18″. Contact us with your dimensions.
