自封袋的質(zhì)量好壞怎么查看？

1、外觀檢查

1. Visual inspection

，不能有氣泡、穿孔、破裂現(xiàn)象;其次，如果有印刷圖文的，應(yīng)目測(cè)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(chǎn)品質(zhì)量存在一定的風(fēng)險(xiǎn)。

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(duì)于外層表面有印刷圖文的自封袋，消費(fèi)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(yīng)附著牢固，不會(huì)輕易掉色或有脫墨現(xiàn)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、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(guó)對(duì)于普通無夾鏈的自封袋或密實(shí)袋尚無標(biāo)準(zhǔn)或行業(yè)標(biāo)準(zhǔn)，只針對(duì)夾鏈自封袋有行業(yè)標(biāo)準(zhǔn)(BB/T0014-2011)，該標(biāo)準(zhǔn)要求，其反復(fù)使用壽命不少于10次，即反復(fù)使用開合應(yīng)不少于10次，且對(duì)夾鏈配合、開啟拉力都有規(guī)定。消費(fèi)者可以手動(dòng)通過開口處的凸楞與凹槽，反復(fù)多次進(jìn)行封口、拉開，檢查夾鏈?zhǔn)欠袼删o適宜及反復(fù)使用情況，過松或過緊都會(huì)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(fèi)者將自封袋用于密封食品，因此消費(fèi)者在購(gòu)買自封袋時(shí)一定要仔細(xì)聞一聞袋子上面是否有刺鼻的有機(jī)溶劑味道，這種味道有可能來自于劣質(zhì)油墨印刷或塑料袋本身材質(zhì)助劑引起，而質(zhì)量好的自封袋應(yīng)是無任何異嗅的，建議消費(fèi)者在購(gòu)買自封袋包裝食品時(shí)盡量選擇無印刷或有少量印刷的產(chǎn)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.
