Whirl-Pak Flat Wire Sampling Bags

The Whirl-Pak Flat Wire Sampling Bags come in 4 and 18-oz bags. These sampling bags are made with one flat wire instead of the traditional round wire. As a result, the flat wire creates a thicker tab, resulting in a heavier closure which is preferred in some applications. The aluminum wire features “Puncture Proof Tabs,” guaranteeing that the wire ends are completely covered. These Tabs eliminate any sharp, cutting, exposed edges, improving the user experience. In addition, 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 simple 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.

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

Resins used in the extrusion of film for WHIRL-PAK Flat Wire Sampling Bags are FDA approved and manufactured in accordance with the requirements for manufacturers of single service containers for milk and milk products.
