PrimaCreator Filament Storage Bags 5-pack

Keep filament dry and protected

This refill set helps protect your 3D printing filament from moisture, dust and dirt. Proper storage is especially important for hygroscopic materials such as nylon (PA), PVA, PETG and TPU. It can help extend storage life and preserve print quality.

What is included

• 5 resealable, reusable vacuum bags measuring 350 × 310 mm
• Zipper closure and valve, suitable for most 1 kg spools
• 10 humidity indicators
• 10 silica gel packets

Important information

A vacuum pump is not included. The bags are intended as a refill for the PrimaCreator Air Tight Filament Storage Set, which includes a hand pump. You can also use your own pump if it fits the valve.

How to use the bags

1. Place the filament spool, a silica gel packet and a clearly visible humidity indicator inside the bag.
2. Close the bag and pump out the air.
3. If the indicator dots remain brown, the filament is dry. If they turn blue, repack the filament with a fresh silica gel packet.
