粘貼令衣物“黃變”(起汞) 原因

Why the sealing tape would change the textile’s color

 

  “黃變”即粘貼的油膠面透過兩層袋子滲透在服裝上,令衣服上有一條4mm寬的黃色痕跡。

黃變

the oil glue surface of the sealing tape has been permeated to the textile according to the two stories’ bag, and which made the textile appear a 4mm width yellow line.

黃變原因:Reason for the color changing:

  • 袋子是低密度材質,例LLDPE、LDPE、PPE。
  • 電暈處理打得太強,在顯微鏡下可以看到袋子表面已打穿孔。
  • 衣服用的染色料有關系,通常出問題的會有杏色、草綠、 粉紅等淺色系較容易出現 “黃變起汞” 情況。
  • 用戶使用油性膠水粘貼雖然粘性較強而且成本便宜, 但油性膠水卻是令衣物布料 “黃變起汞” 真兇。常見商標(LABEL)也會出現相同情況。
  • 本來膠袋、衣服染料及粘貼三種化學成品,不會互相抵觸產生黃變。但由於服裝的流水作業需蒸燙後馬上裝袋,袋內的溫度和濕度使三種化學成品產生抵觸,形成黃變即起汞。

The glue in the tape would react with the dye material and make the textile change its color.
It is so strong when they make the electricity corona treated process, that you can see the bag has been pined out under the observation of the microscope.
It is also related with the dye material, the light series color would suffer the color changing frequently. Such as the grass green ,the pink and so on.
After series of manufacturing processess. The temperature and the humidity mixing in the bag make the textile’s color change.
The high density material can avoid the textile changing its color, such as the BOPP material.
Although the oil glue water sealing tape is high adhesive and enjoy the low cost. But it is the real reason to the “color changing”. The similar phenomenon can be met in the lable.

總結: Summary:

    黃變現象不一定每次都會發生,有些客戶每年發生多次,有些客戶用了十年都從未發生過,因此也誤導了很多用戶不相信有“黃變”的可能,盡管我們怎樣向用戶提出忠告,但他們都誤以為是我們的一種商業手法。其實每1000M/卷服裝袋專用粘貼用在10∼12吋開口的袋子上可以做3300∼4000個袋子,每1000個袋子的成本只增加7∼9分錢。用戶值不值冒得不償失之風險。

The above phenomenon would not cause the “color changing”at every time.Some customers suffer such problem several times, but some customers suffer nothing through ten years usage, so maybe this situation mislead many customers doubt the possibility of the “color changing”. They all consider the sincere advice we gave them is just a commercial practice. As a matter of fact 1000M/roll textile sealing tape can seal 3300 to 4000 bags when be used in the 10~12 inch’s open-end bag, and which just increase your cost to 0.07~0.09 YUAN RMB.We all think is not an good adventure for you all customers to make.

杜絕方法 Solution method:

    用戶必須使用服裝專用粘貼 生產服裝用袋子,雖成本較高 (每千米比油性膠水貴3-5元),但絕不會部生以上“黃變起汞”原因。

the customer shall use the textile sealing tape which is specially be designed for sealing the textile bag. Though the cost would be a little expensive ( about 3~5 YUAN RMB more than the oil glue water cost per kilometer.), but it can make you assure that the textile you packed in the bag with the textile sealing tape would not suffer the “color changing”.
