【Premium Multi-Layer PE+PA+VMPET Material】Crafted from high-cost PE+PA+VMPET composite material, these bags are thicker, tougher, and more durable than standard storage bags. The multi-layer barrier delivers exceptional light-proof, moisture-proof, and oxygen-proof performance—ensuring your filament stays in peak condition for longer. Safe for food contact, they can also be used to store snacks, coffee beans, or other dry foods, adding extra versatility to your purchase.
【Universal Fit for 99% Filament Spools】Measuring 13x15 inches (33x38 cm), these Plus Size 3D printer filament storage bags fit 99% of standard spools(0.5KG–1KG; 1.75mm–3mm). Offering a spacious, universal storage solution for most filaments, they also work perfectly for storing other 3D printing consumables and supplies.
【Effective Light & Moisture Protection】Crafted from thick, light-proof mylar, these 3D filament vacuum sealed bags create a dark, dry, dust-free environment. They prevent moisture absorption and oxidation, stopping filament from becoming brittle, discolored, or powdery—ensuring smoother extrusion and preventing nozzle clogs.
【Reusable & Durable Design】Built with sturdy PE+PA+VMPET multi-layer mylar construction and a double-track seal, these bags are designed for heavy-duty, repeated use. The 4 reusable clips lock the seal tightly to prevent leaks, while the reinforced valve ensures smooth air exhaust and enhanced suction. Monitor the vacuum periodically and re-pump for extended storage (performance may decrease slightly over time).
【Complete 20 PCS Storage Solution】This set includes 20 reusable, light-proof Plus Size vacuum bags and 6 reusable seal clips, providing a complete solution for PLA, PETG, and TPU storage. Keep your workspace tidy and organized while saving space and protecting spools. Maintain your 3D printing supplies in peak condition with this essential storage kit.
