自封袋的质量好坏怎么查看?
发布于:2023/11/13

1、外观检查

1. Visual inspection

,不能有气泡、穿孔、破裂现象;其次,如果有印刷图文的,应目测其印刷图文是否清晰,如果图案不清晰,套印误差过大,也意味着产品质量存在一定的风险。

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、印刷图文附着牢度检查

2. Inspection of printing image and text adhesion fastness

对于外层表面有印刷图文的自封袋,消费者可以用手在外包装袋上往返摩擦几次,看印刷图案是否掉颜色,好的自封袋其印刷图案应附着牢固,不会轻易掉色或有脱墨现象。

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、夹链凸棱凹槽离合松紧适宜度的检查

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

目前我国对于普通无夹链的自封袋或密实袋尚无标准或行业标准,只针对夹链自封袋有行业标准(BB/T0014-2011),该标准要求,其反复使用寿命不少于10次,即反复使用开合应不少于10次,且对夹链配合、开启拉力都有规定。消费者可以手动通过开口处的凸楞与凹槽,反复多次进行封口、拉开,检查夹链是否松紧适宜及反复使用情况,过松或过紧都会影响使用。

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、异味检查

4. Odor inspection

由于许多消费者将自封袋用于密封食品,因此消费者在购买自封袋时一定要仔细闻一闻袋子上面是否有刺鼻的有机溶剂味道,这种味道有可能来自于劣质油墨印刷或塑料袋本身材质助剂引起,而质量好的自封袋应是无任何异嗅的,建议消费者在购买自封袋包装食品时尽量选择无印刷或有少量印刷的产品。

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.
