濟南包裝袋該如何防止老化

How to prevent aging of packaging bags in Jinan

不管什么包裝材料,在經過長久使用后,由外界原因和自身因素,很容易出現老化還有裂紋,當然這就說明我們該換新包裝了。所以防止噸包袋老化是十分重要的,很多人不是很了解這些內容,那么下面我們就一起來看下包裝袋該如何防止老化吧。

No matter what packaging material is used for a long time, it is easy to experience aging and cracking due to external and internal factors. Of course, this indicates that we should replace the packaging. So preventing the aging of ton bags is very important. Many people are not very familiar with these contents. So let's take a look at how packaging bags can prevent aging together.

點就是紫外線,由于包裝袋在存儲、運輸和使用等方面接觸多的就是陽光,陽光中的紫外線具有高能量,能夠促進自由基和氫氧化合物的產生,從而引發聚丙烯中分子鏈的斷裂,所以噸包袋就表現為拉伸能力減弱等。除此之外,還要考慮當地的溫度和濕度的差異。

The first point is ultraviolet radiation. Due to the fact that packaging bags are most exposed to sunlight during storage, transportation, and use, ultraviolet radiation in sunlight has high energy and can promote the production of free radicals and hydroxyl compounds, thereby causing the breakage of molecular chains in polypropylene. Therefore, ton bags exhibit reduced tensile strength. In addition, it is also necessary to consider the differences in local temperature and humidity.

第二點就是日光的光氧化機理,有兩個來源:一、直接的陽光,太陽的直接照射;

The second point is the photooxidation mechanism of sunlight, which has two sources: first, direct sunlight, direct exposure to the sun;

二、間接地陽光,由于空氣中的水汽、灰塵等的反射;兩種主要來源的日光中含有紅外線,會導致多種氧化劑,易降解聚合物。不要小看這方面的影響,經過時間的推移,我們會發現,食品級包裝袋的老化日益嚴重。

2、 Indirect sunlight, due to the reflection of water vapor, dust, and other substances in the air; The two main sources of sunlight contain infrared radiation, which can cause various oxidants and easily degrade polymers. Don't underestimate the impact of this aspect. Over time, we will find that the aging of food grade packaging bags is becoming increasingly severe.
