Icl <br />May 13, 1985. <br />Mr. Jeff Lobb <br />Materials Manager - <br />Lodi Memorial Hospital <br />975 S. Fairmont Avenue <br />Lodi, CA 95240 } <br />Dear Mr. Lobb: <br />In response to your request, I am supplying you with relevant <br />- _- .�_ -�.. _ ,__data.on .the... acceptance .of the Dart impact method of testing <br />polyethylene bags, <br />The American Society for Testing and Materials (A.S.T.M.) has <br />developed a method to test the impact resistance of polyethylene <br />film. This method is called the Free Falling Dart Method, <br />The A.S.T.M. designation for this test method is D1709-67. <br />The test is conducted as follows: <br />A conical shaped weighted dart is dropped from a height <br />of 26 inches onto a stationery piece of polyethylene film of <br />uniform mil thickness. The drop is repeated over 5 <br />different sections of the test film. If 50% of the drops <br />fracture the polyethylene, the film fails at that dart <br />weight measured in grams. <br />It is important to note that the results of the test are <br />greatly influenced by the the quality of the film under <br />the test film. <br />We at Winfield Corporation strongly feel ,that the 165 gram <br />Dart Impact Test significantly provides the hospital with a <br />bag to meet all of the strength. requirements as needed. There <br />are approximately one hundred various types of resin blends <br />-when manufacturing polyethylene film. We feel confident that <br />our 1.5 mil bags are equivalent in strength, based on our resin, <br />to a 3 mil bag made of inferior quality resin. <br />If you have any further questions, please do not hesitate to <br />call. <br />Sincerely, <br />Deirdra A. Cox <br />Marketing <br />cc: P. Doyle,. District Manager <br />Winfield Corp. <br />9750 Distribution Avenue <br />San Diego, CA 92121 <br />(619) 271-4861 <br />
