Whirl-Pak Sampling Bags – Processflow

Development of Whirl-Pak® Bags

Developed over 50 years ago and made in the U.S.A., WhirlPak® bags were the first sterile sample bags on the market. They were designed to provide milk haulers with a container for collecting samples of bulk produced milk. Whirl-Pak® bags made possible the “universal sample system,” which means that a single sample can be used for all tests required for quality control, product content, and legal compliance. Whirl-Pak® sample bags are a co-extrusion of low-density and linear low-density, virgin polyethylene, giving the bags two important characteristics: • Exceptionally clear film — easy to see through • Superior strength — unbreakable sample container They may be used for taking samples of liquids, semi-solids, or solids. Whirl-Pak® bags are patented under Patent No. 2,973,131 and other patents pending. The film thickness varies from 2.25 mils (0.057 mm) to 4.0 mils (0.102 mm), depending on size and style. Because of the high-quality blended polyethylene, a high mil thickness is not required to achieve optimum strength.

Guaranteed Sterile

 

Only Whirl-Pak® bags carry this important feature. +1 Sterilization is the process of sterilizing sealed cartons of Whirl-Pak® bags after manufacturing using ethylene oxide gas at an independent ISO-certified facility. This process saves valuable preparation time and eliminates concern about sample integrity. To ensure the bags are sterile, a Parametric Release Process is used to confirm that all processing parameters are met and maintained throughout the sterilization cycle. The bags are shipped free from human contact in a secure liner bag inside the sealed carton.
