日常生活中,很多东西都容易变质,比如肉类和谷类。这使得食品包装袋的应用变得越来越重要。

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.

食品包装袋实际上是将产品放入密闭的包装袋中,通过一些工具抽出空气,使包装袋内部达到状态。事实上,食品用包装袋是为了长期保持袋内处于高减压状态,低氧化环境使很多微生物没有生存条件。食品包装袋是包装技术的延伸产品,在日常生活中发挥着关键作用。

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.

虽然食品包装袋只有一个名字,但种类不一样。因为食品的多样性,食品包装袋的种类也很多,哪种食品用哪种包装袋包装,食品用袋包装,零散食品用普通北京方便袋包装。

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.

那么食品包装袋的检验方法是怎么样的?

So what is the inspection method of food packaging bags?

选择食品包装袋看、闻、做三件事。

Choose food bags to see, smell and do three things.

一看外包装是否破损,是否有食品生产许可证的QS标志,是否有明确的生产和质量保证日期;

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;

二闻一闻食品包装是否有异味,尤其是与食品直接接触的包装。如果包装袋有香味,要小心。食品包装一定要无味,因为有些带香味的包装袋可能含有过量的挥发性物质;

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装,用手擦拭,看是否会褪色和拉伸,看是否容易损坏。除了关注食品本身,我们还应该关注食品包装是否有影响。因为包装也会影响食品,从而带来身体的隐患。

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.

其中使用食品包装袋需要注意下面的内容:

The following contents should be paid attention to when using food packaging bags:

1.检查泵的好坏:将泵喷嘴靠近脸,然后泵入空气。如果感觉有吸力,说明袋不错。

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.如果袋出现鼓包现象,除了密封不严外,一方面袋内的被子等东西会放气,也会降低度;另一方面,从物理学的角度来看,更密集的数据是有空间的。由于负压的作用,空气分子会随着时间的推移被挤到袋子里,度会逐渐降低。

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.皮革和羽绒制品可以存放在食品包装袋中,但不应完全收紧。

3. Leather and down products can be stored in food packaging bags, but should not be completely tightened.

4.衣服放入收纳袋前,应将包装纸或包装袋取下,否则会影响收紧效果。

4. Before putting clothes into the storage bag, remove the wrapping paper or bag, otherwise the tightening effect will be affected.

5.请把收纳袋里的衣服完全晾干。无需使用防虫剂、防腐剂等。否则,购买的商品会变色和变质。

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.如果袋子上有裂缝或者小孔,可以用普通的宽面透明胶带粘在两边,贴紧就足够了。

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。如果某处温度比较低,就会凝结成水滴。

7. Avoid leaving too much moisture in the bag. If the temperature somewhere is relatively low, it will condense into water droplets.
