              常見檢測自封袋密封性方法
              發布于:2022/03/15 自封袋雖然非常方便,但是密封性能也很重要。在設計自封袋時,需要充分考慮每層材料的性能和厚度,以獲得足夠的阻隔性能。檢測自封袋密封性能的常用方法有三種:
              Although the self sealing bag is very convenient, the sealing performance is also very important. When designing self sealing bags, the performance and thickness of each layer of materials need to be fully considered to obtain sufficient barrier performance. There are three common methods to test the sealing performance of self sealing bags:
              1.無水浸泡法。
              1. Anhydrous immersion method.
              自封袋通常適用于外層材料性能在水的作用下在測試過程中會明顯下降的包裝,如外層為紙質材料的包裝。
              Self sealing bags are usually suitable for packaging where the performance of the outer material will decrease significantly under the action of water, such as packaging with paper material.
              用試液(如與濾紙有明顯色差的有色水溶液)填充樣品,密封后將樣品放在濾紙上,觀察試液從樣品內到外的滲漏情況。應該從兩方面來衡量。也可以放在真空室中,在負壓下測試。
              Fill the sample with test solution (such as colored aqueous solution with obvious color difference with the filter paper), place the sample on the filter paper after sealing, and observe the leakage of test solution from inside to outside of the sample. It should be measured from two aspects. It can also be placed in a vacuum chamber and tested under negative pressure.
              二、真空觀察法。
              2、 Vacuum observation method.
              自封袋的適用材料同上。通過抽真空,產生樣品內部和外部的壓力差,觀察膨脹和釋放真空后樣品形狀的恢復,判斷樣品的密封性能。
              The applicable material of self sealing bag is the same as above. By vacuumizing, the pressure difference inside and outside the sample is generated, and the recovery of sample shape after expansion and vacuum release is observed to judge the sealing performance of the sample.
              第三,城市壓在水里。
              Third, the city is under pressure.
              自封袋通常適用于外層材料性能在水的作用下在試驗過程中不會明顯下降的包裝,如外層采用塑料薄膜的包裝。通過對真空室抽真空,產生浸入水中的樣品內部和外部的壓力差,觀察樣品中的氣體逸出或水分滲入,測量樣品的密封性能。測量密封性能常用的手段是具有真實速率的測試裝置。
              Self sealing bags are usually suitable for packaging in which the performance of the outer material will not decrease significantly under the action of water, such as packaging with plastic film. By vacuumizing the vacuum chamber, the pressure difference between the inside and outside of the sample immersed in water is generated, the gas escape or water infiltration in the sample is observed, and the sealing performance of the sample is measured. The common means to measure the sealing performance is the test device with real rate.
              目前市場上很多商品都存在產品質量問題,總有窮店為了更好地實現目標而鋌而走險。因此,我們在購買自密封袋時要特別注意,自密封袋因其方便易用而被廣泛應用于食品等各個領域。很多人會問如何辨別自封袋是否有害。
              At present, many goods in the market have product quality problems. There are always poor stores who take risks in order to better achieve their goals. Therefore, we should pay special attention when purchasing self sealing bags. Self sealing bags are widely used in various fields such as food because of their convenience and ease of use. Many people will ask how to identify whether self sealing bags are harmful.
              1.用雙眼看。
              1. Look with both eyes.
              無毒包裝袋為白色、全透明或微全透明,材質勻稱。有害密封包裝袋為彩色或白色,但透明度和濁度較弱。塑料表層拉伸不均勻,含有小顆粒。
              The non-toxic packaging bag is white, fully transparent or slightly fully transparent, and the material is symmetrical. The harmful sealed packaging bag is colored or white, but the transparency and turbidity are weak. The plastic surface layer is stretched unevenly and contains small particles.
              2.聽聽你的耳朵。
              2. Listen to your ears.
              當用力搖晃包裝袋時,會發出清晰的聲音,表明是無毒包裝袋。而低噪音是有害的包裝袋。
              When shaking the bag, it will make a clear sound, indicating that it is a non-toxic bag. And low noise is harmful to the packaging bag.
