合格的包裝袋的檢驗方法有哪些

2021/10/10 分類:材料新聞 1132 0

如今的包装袋五花八门，不同厂家生产出来的质量也各不相同吗，像飞富润为大家介绍一下合格的包裝袋的檢驗方法有哪些？

1、利用水检查塑料包装袋：将塑料袋放入水中，观察塑料袋是否浮在水面上。浮在水面的是无毒的塑料袋，沉在水中的是有毒的塑料袋。

2、搖晃塑料包裝袋檢查：用簡單的方法，用手抓住塑料袋搖晃幾下，發出聲音的是那個透明幹淨的是無毒的塑料袋，發出聲音的是那個沈重的聲音的話說明是有毒的塑料袋。

3、燃烧塑料袋检查)无毒的塑料袋易燃。仔细观察，燃烧时火焰的颜色顶端是黄色，局部是蓝色，然后随着燃烧像蜡烛一样落下，有石蜡一样的气味。有毒的塑料袋很难燃烧，离开火源后很快消失，前端部为黄色，局部为绿色，燃烧后呈拉丝状态。

4、通过塑料包装袋本身的颜色和与塑料袋的接触来检测塑料包装袋。无毒性塑料袋为乳白色或无色透明，用手触摸有润滑感; 有毒的塑料袋颜色浑浊，以黄、红、黑为主，用手摸会有点粘。

以上是对于“合格的包裝袋的檢驗方法有哪些”的介绍，希望对您有所帮助。飞富润包装彩印是一家专业的包装袋生产厂家，若您有需要的话可直接联系在线客服，获取相关资料。

"But you don't get all the whales you see, by a long shot. Many a whale gets away before you can fasten to him, and many another whale, after you have laid on and fastened, will escape you. He sinks, and tears the iron loose; he runs away to windward ten or twenty miles an hour, and you must cut the line to save your lives; he smashes the boat, and perhaps kills some of his assailants; he dies below the surface, and when he dies there he stays below, and you lose him; and sometimes he shows[Pg 66] such an amount of toughness that he seems to bear a charmed life. We fight him with harpoon and lance, and in these later days they have an invention called the bomb-lance or whaling-gun. A bomb-shell is thrown into him with a gun like a large musket, and it explodes down among his vitals. There's another gun that is fastened to the shaft of a harpoon, and goes off when the whale tightens the line; and there's another that throws a lance half-way through him. Well, there are whales that can stand all these things and live. The reply came slowly. "No; her husband is quite another man; this man's wife has been dead for years. No, Charlotte Oliver lives in--hark!" "Since the hour of her marriage she has never gone into her chamber without locking the door; she has never come out of it unarmed." The only purpose of my publication was to convince everybody of this, and thereby prevent the repetition of such a scandalous scene. An interpreter translated to the accused the questions put by the judge, who understood the replies, though he was not allowed to speak excepting in English. Dick, examining with the thoroughness of an expert, with Jeff’s and his chum’s life perhaps depending on his care, stated that he saw no damage to the waterproofed coverings of the water supports. Declaring that they would stand by and watch the airplane, Sandy and Dick watched Larry and Jeff get settled, Dick spun the propeller to pump gas into the still heated cylinders, Jeff gave the “switch-on—contact!” call, Dick, pulling down on the “prop,” sprang aside to avoid its flailing blades, and the amphibian’s engine took up its roar. He transmitted the suggestion. Almost as his hand touched the cable and twitched at it, his other hand, as he lay with his weight on his chin, face and chest, contacted something else—a large, roundish object, feeling like a spare landing wheel tire. It was short and to the point upon Cairness's part, and having finished he stood up. "I don't believe a word of hit," said the woman, who yet showed that she was touched by the allusion to the Baptist Church, as the Deacon had calculated, for most of the people of that section professed to be of that denomination. "What'll yo' gi' me for them chickens?" HoME 学生妹被老师 ENTER NUMBET 0010www.hyves.org.cn
