Material: PE + PA

Temperature resistance: - 20 ~ 100℃

Color: Advanced gray + transparent

Size:30*34mm

Characteristic:

1. Airtight: the "bite in" clip chain can lock the pocket firmly with one pinch

2. Simple sealing, easy and convenient: the air extraction tool is aligned with the air extraction port and pressed tightly, then the manual air extraction can be realized

3. Reuse, saving and environmental protection: multi layer composite material, recyclable

4. Dry and wet dual-purpose, dust and moisture-proof: effectively prevent consumables from oxidation and moisture-proof under vacuum environment

When the filament  exposed to damp air for a long time, it becomes brittle and  printing fails.

Vacuum bag is a great way to solve this problem by keeping the filament in vacuum storage when you're not using it. And can be reused  many times.
