产品名称：Whirl-Pak可标记宽钢丝封口采样袋 4 oz Whirl-Pak Flat Wire Bags with Write-On Strip

These 4-oz. bags are made with one flat wire, rather than the traditional round wires. The flat wire provides a thicker tab, resulting in a heavier closure which is preferred in some applications. The aluminum wire features “PUNCTURE PROOF TABS,” so the wire ends are completely covered, eliminating any sharp, cutting, exposed edges. The aluminum will not rust when coming in contact with water or other liquids.

The white, write-on strip makes sample identification easier and more convenient. It’s easy to write on this white strip using an ordinary ballpoint pen, pencil, or felt-tip marker. The paper-like finish virtually eliminates ink smearing, and provides a surface that will accept a variety of writing instruments.

Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180° F (82° C). Bags can be frozen to any temperature, even liquid nitrogen – careful handling required after freezing. All bags are sterilized after manufacturing.
