隨著市場上熟食品的不斷增加，市場對(duì)于真空袋的需求也逐漸增加，而擔(dān)心出現(xiàn)的問題就是放置一段時(shí)間過后，出現(xiàn)漲袋的現(xiàn)象，那么導(dǎo)致這種情況發(fā)生的原因有哪些呢？

With the continuous increase of cooked food in the market, the market demand for vacuum bags is also gradually increasing. The worry is that the bags will rise after being placed for a period of time. What are the reasons for this?

1、運(yùn)輸過程及銷售商倉庫的儲(chǔ)存溫度，很多產(chǎn)品因?yàn)槭覝亻g斷高于37攝氏度以上，一冷一熱，內(nèi)側(cè)產(chǎn)生冷凝水等導(dǎo)致。

1. During the transportation process and the storage temperature of the seller's warehouse, many products are caused by the intermittent room temperature higher than 37 ℃, one cold and one hot, and condensate water is generated inside.

2、食品添加劑之間反應(yīng)產(chǎn)生氣體或食品添加劑與配料反應(yīng)產(chǎn)生氣體。

2. The reaction between food additives produces gas or the reaction between food additives and ingredients produces gas.

3、真空袋內(nèi)的細(xì)菌繁殖往往會(huì)產(chǎn)生氣體。

3. The bacteria in the vacuum bag often produce gas.

在材質(zhì)沒問題的情況下，如果不完全，里面的細(xì)菌繁殖而導(dǎo)致的漲袋現(xiàn)象，這種情況通常發(fā)生在肉制品包裝的使用中，檢驗(yàn)方法很簡單，用該袋子裝適量大米(大米一般不會(huì)有產(chǎn)氣菌)抽真空后放置半個(gè)月，如沒有出現(xiàn)漲袋現(xiàn)象，那說明是使用過程中不完全導(dǎo)致的，此時(shí)需要調(diào)整一下的工藝。

If the material is OK, if the sterilization is not complete, the bacteria inside will multiply and cause the bagging phenomenon. This situation usually occurs in the use of meat product packaging. The inspection method is very simple. Fill an appropriate amount of rice in this bag (rice generally does not have gas producing bacteria) and leave it for half a month after being emptied. If there is no bagging phenomenon, it indicates that it is caused by incomplete sterilization during use, At this time, the sterilization process needs to be adjusted.

4、密封性與通透性

4. Sealing and permeability

食品在裝袋后，需要對(duì)其進(jìn)行熱壓封合，而這一步質(zhì)量高低會(huì)直接影響密封性能。如果封邊不嚴(yán)，會(huì)導(dǎo)致漏氣，空氣將會(huì)從漏氣部位進(jìn)入真空袋。

After the food is bagged, it needs to be sealed by hot pressing, and the quality of this step will directly affect the sealing performance. If the edge is not tightly sealed, it will lead to air leakage, and air will enter the vacuum bag from the air leakage part.
