如何判斷包裝膠帶的質量大家知道嗎?

來源:http://www.cdhpd.com 發布時間:2019-12-09

  什么是包裝膠帶?顧名思義,它是用來密封沉重的紙箱。密封膠帶選擇不好,會造成一系列的影響。膠帶充足,膠帶質量好,膠帶。重紙箱包裝膠帶有:印刷包裝膠帶、無水牛包裝膠帶、透明包裝膠帶、彩色包裝膠帶等。印刷封口膠帶:是在膠帶上印刷公司的具體標志和文字起到宣傳作用。這種膠帶的優點是印刷效果好,粘腳,張力好,不易斷裂。水牛皮膠帶看起來像一個水貼紙,但它自己粘不上。具有耐水、粘度大、抗拉強度高、不翹邊、耐候性穩定等優點。于透明密封帶和彩色密封帶,我們比較常見。
  What is packing tape? As the name suggests, it is used to seal heavy cartons. Bad selection of sealing tape will cause a series of effects. Enough tape, good quality and environmental protection. Heavy carton packaging tape includes: printing packaging tape, non buffalo packaging tape, transparent packaging tape, color packaging tape, etc. Printing sealing tape: it is used to print the company's specific logo and text on the tape to play a promotional role. The advantages of the tape are good printing effect, foot sticking, good tension and not easy to break. Buffalo skin tape looks like a sticker, but it doesn't stick on itself. It has the advantages of water resistance, high viscosity, high tensile strength, no edge warping, stable weather resistance, etc. As for transparent sealing tape and color sealing tape, we are quite common.

  很多客戶在購買重紙箱封箱膠帶時,不會做太多的作業,認為可以把重紙箱封箱就行了。其實并不是,我們在選購時要注重這幾個方面。膠帶的厚度,一些不法商家會增加膠帶里面的一些雜質厚度。還有一個小竅門來分辨是否添加了雜質,就是看膠帶的顏色已經變成了黃色還是綠色,不要聽商家糊弄,因為儲存時間太長或太濕等等。另一方面是看帶碼的數量,有的商家說他們的帶碼是幾百到一千多才有,這里要說明的是,有的商家說的是帶碼的數量而不是碼的數量。碼數是膠帶經過所有距離后的長度。
  Many customers will not do too much work when buying the heavy carton sealing tape, and think that it is OK to seal the heavy carton. In fact, we should pay attention to these aspects when purchasing. The thickness of the tape, some illegal businesses will increase the thickness of some impurities in the tape. There is also a trick to distinguish whether impurities have been added, that is, to see whether the color of the tape has turned yellow or green. Don't listen to the merchants' teasing, because the storage time is too long or too wet, etc. On the other hand, it depends on the number of codes. Some businesses say their codes are hundreds to more than a thousand. What we want to say here is that some businesses say the number of codes rather than the number of codes. The number of yards is the length of the tape after all distances.
  我們應該如何選擇?如何判斷膠帶的質量?這類似于診斷,一看,兩聞,三診斷。看膠帶的顏色,光澤越高,顏色越白,雜質越純越少。光澤越深,膠帶破裂的可能性越大。用手觸摸,越薄越軟越好。如果密封帶有酸味,質量也不好。特別是在低溫環境下,會很快開裂并失去粘度。
  How should we choose? How to judge the quality of the tape? This is similar to diagnosis, one look, two smells, three diagnoses. Look at the color of the tape. The higher the luster, the whiter the color and the less impurities. The deeper the gloss, the more likely the tape will break. Touch with your hand, the thinner, the softer, the better. If the seal is sour, the quality is not good. Especially at low temperature, it will crack quickly and lose viscosity.
