20-Pack Filament Storage Bags

This set contains 20 reusable vacuum-sealed bags sized at 12.6 by 13.4 inches. The PA+PE material is wear-proof and scratch-proof for repeated use. Each bag features a black light-proof side and a transparent side with a label for recording material type and sealing date. A vacuum pump is not included.

Makers needing moisture protection for multiple

The plus-size dimensions fit most 0.5 kg, 0.75 kg and 1 kg spools from various brands. Compatibility covers 1.75 mm, 2.85 mm and 3 mm diameters across PLA, PETG, TPU and similar materials. Builders who require an integrated pump or smaller 30 cm bags should look elsewhere.

Capacity for standard spools with headroom

Each bag accommodates a single 1 kg reel with space to seal, while the 32 by 34 cm footprint handles larger spools that do not fit 30 cm alternatives. The vacuum design removes air to preserve filament quality over time. The 20-pack quantity supports bulk storage for active multi-material printing.

Questions about this item

What filament spool sizes fit inside the 12.6 by 13.4 inch bags?

The bags accommodate most 0.5 kg, 0.75 kg and 1 kg spools of 1.75 mm, 2.85 mm or 3 mm filament including PLA, PETG and TPU.

Will the bags work with filament I already have stored in 30 cm containers?

The 32 cm by 34 cm bags are larger than 30 cm containers so existing spools will fit with room to spare.

How can I verify the vacuum seal is holding after I close the bag?

A properly sealed bag stays compressed and the zipper remains flat; the label on the transparent side lets you note the material and date without opening it.
