濟(jì)南塑料袋食品包裝袋的作用和檢驗(yàn)方法

來源:http://wujikeji.com/ 日期:2022-03-15

日常生活中,很多東西都容易變質(zhì),比如肉類和谷類。這使得食品包裝袋的應(yīng)用變得越來越重要。
In daily life, many things are easy to deteriorate, such as meat and cereals. This makes the application of food packaging bags more and more important.
食品包裝袋實(shí)際上是將產(chǎn)品放入密閉的包裝袋中,通過一些工具抽出空氣,使包裝袋內(nèi)部達(dá)到狀態(tài)。事實(shí)上,食品用包裝袋是為了長期保持袋內(nèi)處于高減壓狀態(tài),低氧化環(huán)境使很多微生物沒有生存條件。食品包裝袋是包裝技術(shù)的延伸產(chǎn)品,在日常生活中發(fā)揮著關(guān)鍵作用。
In fact, the food packaging bag is to put the product into the closed packaging bag and extract the air through some tools to make the inside of the packaging bag reach the state. In fact, the purpose of food packaging bag is to keep the bag in a high decompression state for a long time. The low oxidation environment makes many microorganisms have no living conditions. Food packaging bag is an extension of packaging technology and plays a key role in daily life.
雖然食品包裝袋只有一個(gè)名字,但種類不一樣。因?yàn)槭称返亩鄻有?,食品包裝袋的種類也很多,哪種食品用哪種包裝袋包裝,食品用袋包裝,零散食品用普通方便袋包裝。
Although there is only one name for food packaging bags, the types are different. Because of the diversity of food, there are many kinds of food packaging bags. Which kind of food is packaged in which kind of packaging bag, food is packaged in bags, and scattered food is packaged in ordinary convenience bags.
那么食品包裝袋的檢驗(yàn)方法是怎么樣的?
So what is the inspection method of food packaging bags?
選擇食品包裝袋看、聞、做三件事。
Choose food bags to see, smell and do three things.
一看外包裝是否破損,是否有食品生產(chǎn)許可證的QS標(biāo)志,是否有明確的生產(chǎn)和質(zhì)量保證日期;
I. check whether the outer package is damaged, whether there is QS mark of food production license, and whether there is a clear production and quality assurance date;

二聞一聞食品包裝是否有異味,尤其是與食品直接接觸的包裝。如果包裝袋有香味,要小心。食品包裝一定要無味,因?yàn)橛行阄兜陌b袋可能含有過量的揮發(fā)性物質(zhì);
Second, smell whether the food packaging has peculiar smell, especially the packaging in direct contact with food. Be careful if the bag smells. Food packaging must be tasteless, because some flavored packaging bags may contain excessive volatile substances;
三用手摸摸食品的外包裝,用手擦拭,看是否會(huì)褪色和拉伸,看是否容易損壞。除了關(guān)注食品本身,我們還應(yīng)該關(guān)注食品包裝是否有影響。因?yàn)榘b也會(huì)影響食品,從而帶來身體的隱患。
Third, touch the outer package of food with your hand and wipe it with your hand to see whether it will fade and stretch and whether it is easy to be damaged. In addition to paying attention to the food itself, we should also pay attention to whether the food packaging has an impact. Because packaging will also affect food, which will bring hidden dangers to the body.
其中使用食品包裝袋需要注意下面的內(nèi)容:
The following contents should be paid attention to when using food packaging bags:
1.檢查泵的好壞:將泵噴嘴靠近臉,然后泵入空氣。如果感覺有吸力,說明袋不錯(cuò)。
1. Check whether the pump is good or bad: put the pump nozzle close to the face, and then pump air. If you feel suction, the bag is good.
2.如果袋出現(xiàn)鼓包現(xiàn)象,除了密封不嚴(yán)外,一方面袋內(nèi)的被子等東西會(huì)放氣,也會(huì)降低度;另一方面,從物理學(xué)的角度來看,更密集的數(shù)據(jù)是有空間的。由于負(fù)壓的作用,空氣分子會(huì)隨著時(shí)間的推移被擠到袋子里,度會(huì)逐漸降低。
2. If the bag is bulging, in addition to the lax sealing, on the one hand, the quilt and other things in the bag will deflate and reduce the tightness; On the other hand, from a physical point of view, more dense data has space. Due to the negative pressure, air molecules will be squeezed into the bag over time, and the temperature will gradually decrease.
3.皮革和羽絨制品可以存放在食品包裝袋中,但不應(yīng)完全收緊。
3. Leather and down products can be stored in food packaging bags, but should not be completely tightened.
4.衣服放入收納袋前,應(yīng)將包裝紙或包裝袋取下,否則會(huì)影響收緊效果。
4. Before putting clothes into the storage bag, remove the wrapping paper or bag, otherwise the tightening effect will be affected.
5.請把收納袋里的衣服完全晾干。無需使用防蟲劑、防腐劑等。否則,購買的商品會(huì)變色和變質(zhì)。
5. Please dry the clothes in the storage bag completely. There is no need to use insect repellents, preservatives, etc. Otherwise, the purchased goods will change color and deteriorate.
6.如果袋子上有裂縫或者小孔,可以用普通的寬面透明膠帶粘在兩邊,貼緊就足夠了。
6. If there are cracks or small holes in the bag, it can be stuck on both sides with ordinary wide face transparent tape, which is enough.
7.避免在袋子里留下太多的水分。如果某處溫度比較低,就會(huì)凝結(jié)成水滴。
7. Avoid leaving too much moisture in the bag. If the temperature somewhere is relatively low, it will condense into water droplets.
