Chamber sealer pouches don’t require the internal mesh grooves needed by edge sealer bags, which results in an overall more affordable alternative. To sweeten the deal, these chamber sealer pouches are 100% plastic neutral thanks to our partnership with Plastic Bank. Product Dimensions 280mm x 250mm | 11.0 x 9.8 in Additional Features Food-safe and free from harmful BPA plastics. Only compatible with the Anova Precision Chamber Vacuum Sealer and other chamber-style sealers. Not for use with edge sealing vacuum sealers.
