Description
Engineered for professional 3D printing environments.
Our premium vacuum storage bags protect filaments from moisture absorption, UV light degradation, dust, and physical scratches.
Designed for B2B buyers, filament wholesalers, and high-volume print farms, these bags extend filament shelf life, reduce print failures (stringing, bubbling, clogging), and streamline inventory management with an integrated label system.
Light-Proof Opacity
Black side blocks UV rays – essential for light-sensitive filaments (pump not included).
True Plus Size
12.6 x 13.4 in (32 x 34 cm) – perfectly fits all major 1kg spool brands.
PA+PE Durability
Upgraded multi-layer composite – wear-proof, scratch-proof, and puncture-resistant.
Smart Label System
Transparent window with writable label – track material type & sealing date instantly.
Why B2B Buyers Choose This Storage Solution
Reduce Waste – Prevents costly print failures from moisture-softened or brittle filaments.
Long-Term Preservation – Maintains ideal material mechanical properties for up to 12+ months.
High Reusability – Durable PA+PE construction withstands hundreds of vacuum cycles.
Efficient Logistics – Flat packaging reduces storage footprint; lightweight design lowers shipping costs.
Customizable – Bulk orders support custom branding, color options, and pre-printed labels.
Zero Contamination – Airtight seal protects spools from dust, oil, and environmental pollutants.
Step-by-Step Usage Guide
- Insert the filament spool (place a desiccant packet inside for optimal dryness).
- Close the double-seal zipper, pressing firmly to ensure an initial airtight seal.
- Attach a vacuum pump (hand pump or electric) to the built-in valve and extract remaining air until the bag compresses tightly around the spool.
- Use the white label area on the transparent side to record the filament type, sealing date, and any batch reference for quick identification.
Note: The vacuum pump is not included and must be purchased separately. These bags are compatible with standard 3D printer filament vacuum pumps.
Frequently Asked Questions (FAQ)
What filament sizes fit in this vacuum bag?
The bag fits all standard 0.5kg, 0.75kg, and 1kg spools with filament diameters of 1.75mm, 2.85mm, and 3.0mm.
Is the vacuum pump included with the bag?
No, the vacuum pump is sold separately. The bag features a standard valve compatible with most hand or electric vacuum pumps.
Why is the light-proof feature important for filament storage?
Light exposure degrades UV-sensitive materials like clear PETG and certain nylons, causing brittleness and discoloration. The black side blocks 99% of light to preserve material integrity.
What materials are compatible with these storage bags?
The bags are compatible with PLA, PETG, TPU, ABS, Nylon, PVA, PC, ASA, and other common 3D printing filaments.

Rayon –
The bags work very well. I bought the 20 pack and had zero bag leaks. The pump didn’t draw much power, and is amazingly quiet. It seals real well. Just be aware that you need a USBA power source. The pump is not rechargeable. You connect it to the USB power source via the cable connected to the pump.
When you seal your filament ensure the tip is toward the inside of the reel. This will avoid the sharp edge of the tip from puncturing the bag immediately, or over time.
The only negative thing I can say, is that you cannot just buy refill bags. You have to get the whole kit. Seems like a waste of resources to have to keep buying the whole kit when there’s nothing wrong with the pump.
At the time of writing this review, the 30 pack is the best buy for your money. It comes out to 1 USD / bag, which includes the pump.
One last important thing to know after a few years of experience, is to ensure you completely zip the bag closed. This might sound obvious, but it is real easy to have an almost unnoticeable bump. The bag will seal, but when you go to take the reel out of the bag weeks or months later, you will see that it is not sealed anymore. Either use the provided clip to seal the zipper, or lie it on a flat table and slide across the sealing area with your finger. Do this a few times until you don’t feel the bumps anymore. This is true of all these type of bags, not just this brand.
To sum it up, I highly recommend this pump and bags. I’m getting ready to reorder the 30 pack today.
