      自封袋的質量好壞怎么查看?
      發布于:2023/11/13

      1、外觀檢查

      1. Visual inspection

      ,不能有氣泡、穿孔、破裂現象;其次,如果有印刷圖文的,應目測其印刷圖文是否清晰,如果圖案不清晰,套印誤差過大,也意味著產品質量存在一定的風險。

      Firstly, there should be no bubbles, perforation, or rupture; Secondly, if there are printed graphics and text, it is necessary to visually check whether the printed graphics and text are clear. If the pattern is not clear and the overprint error is too large, it also means that there is a certain safety risk to the product quality.

      2、印刷圖文附著牢度檢查

      2. Inspection of printing image and text adhesion fastness

      對于外層表面有印刷圖文的自封袋,消費者可以用手在外包裝袋上往返摩擦幾次,看印刷圖案是否掉顏色,好的自封袋其印刷圖案應附著牢固,不會輕易掉色或有脫墨現象。

      20231024060042332.jpg

      For self sealing bags with printed graphics and text on the outer surface, consumers can rub their hands back and forth on the outer packaging bag several times to see if the printed pattern has lost color. A good self sealing bag should have its printed pattern firmly attached and not easily lose color or have deinking phenomenon.

      3、夾鏈凸棱凹槽離合松緊適宜度的檢查

      3. Inspection of the suitability of the clutch tightness of the chain clamping convex groove

      目前我國對于普通無夾鏈的自封袋或密實袋尚無標準或行業標準,只針對夾鏈自封袋有行業標準(BB/T0014-2011),該標準要求,其反復使用壽命不少于10次,即反復使用開合應不少于10次,且對夾鏈配合、開啟拉力都有規定。消費者可以手動通過開口處的凸楞與凹槽,反復多次進行封口、拉開,檢查夾鏈是否松緊適宜及反復使用情況,過松或過緊都會影響使用。

      At present, there is no national or industry standard for ordinary chain free self sealing bags or compact bags in China. Only the industry standard (BB/T0014-2011) is available for chain free self sealing bags. This standard requires that their repeated service life should not be less than 10 times, that is, the opening and closing times should not be less than 10 times, and there are regulations for chain clamping coordination and opening tension. Consumers can manually seal and open the opening multiple times through the protrusions and grooves, and check whether the clamping chain is suitable for tightness and repeated use. If it is too loose or too tight, it will affect the use.

      4、異味檢查

      4. Odor inspection

      由于許多消費者將自封袋用于密封食品,因此消費者在購買自封袋時一定要仔細聞一聞袋子上面是否有刺鼻的有機溶劑味道,這種味道有可能來自于劣質油墨印刷或塑料袋本身材質助劑引起,而質量好的自封袋應是無任何異嗅的,建議消費者在購買自封袋包裝食品時盡量選擇無印刷或有少量印刷的產品。

      Due to the fact that many consumers use self sealing bags to seal food, they must carefully smell the pungent organic solvent smell on the bag when purchasing it. This smell may be caused by poor quality ink printing or plastic bag material additives, and high-quality self sealing bags should be odorless, It is recommended that consumers choose products without printing or with a small amount of printing when purchasing food packaged in self sealing bags.
