White-valve filament bags, compact pump and packaging in a kit

YueSheng Packaging

3D Filament Vacuum Bags

Keep the spool you have opened ready for the next print. Pack spare colours separately and organise them beside the printer or on a storage shelf, so changing materials starts with finding the right spool.

Choose the bag around the spool diameter and width, leaving clear space at the zipper. Bags can be combined with a compact or tall pump, sealing clips and packaging to suit the kit you want to purchase.

Storage bags do not replace filament drying. Dry damp filament separately using the material supplier’s instructions.

Organising spools between print jobs

Plan for both the spool currently in use and the spare materials waiting on the shelf. Bag size and kit contents should follow that routine.

The spool beside the printer

For a spool that is used often, choose a bag with enough opening clearance for repeated packing and removal. Keep the sealing clip and the selected pump close to the storage area.

Spare colours and materials

Separate spare spools by colour or material instead of placing several loose spools together. Check the diameter and width of each spool before choosing a common bag size for a kit.

At the printer and on the shelf

These views show individual spools, grouped storage and kit arrangements in a printing workspace. Choose the bags and accessories for the spools you actually use.

Prepare filament and accessories at the workbench — A filament kit beside the printer brings the bags, compact pump and clips into one storage arrangement. Kit contents are selected for the order.

Keep a spare spool beside the printer — A spare spool kept beside the printer. Allow room at the zipper when selecting a bag for the spool diameter and width.

Organise individually packed spools on the shelf — Individually packed spools arranged on a shelf. Separate colours or materials before planning the bag quantity for a storage kit.

Specifications

Start with spool dimensions, then compare the bag construction and pump options listed here. The weight printed on a spool is not a reliable measure of its outer size.

Before you order

Will every 1 kg spool fit?

Spools with the same filament weight can have different flange diameters and widths. Measure both dimensions and allow extra room for the bag to close without the spool pressing against the zipper.

Can vacuum storage replace drying?

The bag is for storing filament between print jobs. If the material has already absorbed moisture, use a separate drying process appropriate for that material before printing; evacuation is not a drying specification.

What should I specify for a complete kit?

Tell us the spool dimensions, bag quantity, preferred compact or tall pump and packaging requirements. Sealing clips, desiccant and the number of pumps can then be arranged around the kit rather than inferred from a photograph.
