隨著對(duì)食品質(zhì)量和衛(wèi)生的要求越來(lái)越嚴(yán)格，作為一種能夠封閉的包裝存儲(chǔ)工具，自封袋很快受到了人們的喜愛。那么判斷濟(jì)南自封袋是否合格呢？

With the increasingly stringent requirements on food quality and hygiene, as a packaging and storage tool that can be sealed, self-sealing bags have quickly become popular. So is Jinan self-sealing bag qualified?

外觀檢查

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(guò)大，也意味著產(chǎn)品質(zhì)量存在一定的風(fēng)險(xiǎn)。

There shall be no bubble, perforation or fracture; 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, the overprint error is too large, which also means that there is a certain safety risk in the product quality.

印刷圖文附著牢度檢查

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 the self-sealing bag with printed graphics and text on the outer surface, consumers can rub the outer packaging bag several times with their hands to see if the printed pattern has lost color. The printed pattern of a good self-sealing bag should be firmly attached, and will not easily lose color or have deinking.

夾鏈凸棱凹槽離合松緊適宜度的檢查

Check the tightness of the clutch of the chain clamping convex groove

目前我國(guó)對(duì)于普通無(wú)夾鏈的自封袋或密實(shí)袋尚無(wú)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(guò)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(guò)松或過(guò)緊都會(huì)影響使用。

At present, there is no national standard or industrial standard for ordinary self-sealing bags or compact bags without chain clips in China. Only the industry standard (BB/T0014-2011) is available for self-sealing bags with chain clips. This standard requires that the repeated service life of the bags should not be less than 10 times, that is, the repeated use of the opening and closing should not be less than 10 times, and there are provisions for the chain clip coordination and opening tension. Consumers can manually seal and open the opening repeatedly through the ridges and grooves at the opening to check whether the clamping chain is suitable for tightness and repeated use. Too loose or too tight will affect the use.

異味檢查

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(lái)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(wú)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(wú)印刷或有少量印刷的產(chǎn)品。

Because many consumers use self-sealing bags to seal food, consumers must carefully smell whether there is a pungent organic solvent smell on the bag when purchasing self-sealing bags. This smell may be caused by poor quality ink printing or plastic bag material additives, and the self-sealing bags with good quality should have no smell, It is suggested that consumers should try to choose products without printing or with a small amount of printing when purchasing food in self-sealing bags.
