如何判斷真空包裝袋是否合格

2021/10/05 分類:材料新聞 1191 0

当前市场上，基本上所有产品都使用了包装袋进行包装，不管是食品、工业、医药行业。而每个行业使用的包装对于要求也不同，不同产品使用不同包装，下面就为大家介绍一下，如何判斷真空包裝袋是否合格？

1、從封口密合性來觀察，如封口出現一些纖細的小縫此判定爲不合格産品。

2、從外觀視覺來觀察，以視覺查看複合真空包裝袋表面有無顯著的擦傷和針孔。要點查看封口有無汙染。無法立刻由視覺查看斷定，稍有忽略是形成日後滲漏糜爛的緣由。查看此封口瑕疵可利用一種加有染料的表面活劑噴于封口內，觀其透過與否，來分辨封口的密合性。

3、是封口強度試驗觀察，將查驗的複合真空包裝袋的封口，裁下寬15mm長條形，用全能材料測定儀以300±20mm/min速度，測定封口強度，通常複合袋封口強度應達2334N/15mm。

"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.aab33.com.cn
