Filament Storage Bags with Auto Pump 20Pcs With High Speed PETG Filament Black

• Precise airtight vacuum seal — make it last ：These extra‑large filament storage bags use an upgraded valve and zipper system, but proper sealing is essential. Before vacuuming, press the zipper fully closed with no gaps and hold the pump firmly against the valve to ensure tight suction. This helps prevent air leakage over time.
• Extra‑large 14.9 x 13 inch bags — broad filament compatibility: Designed to fit Bambu Lab spools and more than 99% of standard 1 kg 1.75 mm filament rolls, giving you a roomy, universal filament storage solution for most filaments.
• 【ULTRA-HIGH FLOW & 600mm/s SPEED】Engineered with advanced High Flow technology, this PETG filament supports extreme printing speeds up to 600 mm/s (optimal below 300 mm/s). Unlike standard PETG that restricts you to slow printing, it delivers consistent extrusion without clogging or under-extrusion—cutting printing time by up to 70% while maintaining excellent surface quality.
• 【LESS-STRINGING & SMOOTH TEXTURE】 Say goodbye to the messy blobs and excessive stringing that plague traditional PETG. By optimizing the material viscosity and flow rate, we’ve achieved a smooth, glossy finish with exceptional layer adhesion. Your prints will come off the bed with clean surfaces and strong structural integrity, requiring minimal post-processing.
• 【TOUGHNESS & HEAT RESISTANCE】 Combining the ease of PLA with the durability of ABS, our PETG filament is outdoor-ready. It features high impact strength and heat resistance, making it perfect for functional prototypes, mechanical parts, and weather-resistant components that won't crack under stress or pressure.
