What are write-on block bags? Write-on block bags feature a white opaque panel printed directly on the bag surface that accepts permanent marker, pen, or labels for product identification. The white block provides contrast for easy reading and won't smudge or fade during normal handling. What is a side-welded zipper? Side-welded zippers are heat-sealed along the side edges of the bag during manufacturing, creating a stronger seal than standard heat-sealed closures. This construction prevents zipper separation and provides more reliable tamper resistance. Are these bags reusable? Yes, the durable LDPE construction and reinforced zipper allow these bags to be opened and resealed multiple times without compromising seal integrity, making them ideal for parts inventory and sample storage applications.
