      膠袋與PE膠袋有什么區別?
      發布于:2024/02/06

      膠袋、PO膠袋都是透明的,感到有所疑慮,今天膠袋廠就為大家一一講解。在使用中的膠袋為什么都會是透明的,這主要是因為任何晶體型開口劑對膠袋的透明度都有一定的負面影響,即會在薄膜內形成一種霧氣。但因產品使用的開口劑品種不同,影響程度也會有所不同,然而影響膠袋透明度的因素主要有以下幾點:

      Both plastic bags and PO plastic bags are transparent, so I have some doubts. Today, the plastic bag factory will explain one by one to you. Why are all plastic bags in use transparent? This is mainly because any crystal type opening agent has a certain negative impact on the transparency of the plastic bag, which will form a mist inside the film. However, due to the different types of opening agents used in the product, the degree of influence may also vary. However, the main factors affecting the transparency of the plastic bag are as follows:

      開口劑的化學純度?;瘜W合成晶體的純度遠高于天然礦物。因此,由化學合成工藝制造的開口劑,其透明度明顯高于天然礦物。

      The chemical purity of the opening agent. The purity of chemically synthesized crystals is much higher than that of natural minerals. Therefore, the transparency of the opening agent manufactured by chemical synthesis process is significantly higher than that of natural minerals.

      開口劑的加入量。晶體型開口劑因來源不同,其中重質晶體是指天然礦物類開口劑,另一種是輕質晶體是指由化學合成的開口劑。兩者之區別在于,在相同體積下,重量有明顯的差別。

      The amount of opening agent added. Crystal type opening agents come from different sources, with heavy crystals referring to natural mineral type opening agents and light crystals referring to chemically synthesized opening agents. The difference between the two is that there is a significant difference in weight under the same volume.

      開口劑的光折射率。直射光穿越兩種不同物質的接觸界面時,如果兩種不同物質具有相同的折射率,則穿越的直射光在原入射角的線向范圍內損失小。如果兩種不同物質的折射率相差越大,則穿越的直射光在原入射角的線向范圍內損失越大。因此天然滑石粉、二氧化硅均對直射光造成較大的衰減,對膠袋的透明度有明顯的影響。

      The refractive index of the opening agent. When direct light passes through the contact interface between two different substances, if the two substances have the same refractive index, the loss of the passing direct light is small within the linear range of the original incident angle. If the difference in refractive indices between two different substances is greater, the direct light passing through will lose more in the linear range of the original incident angle. Therefore, natural talc powder and silica both cause significant attenuation of direct light and have a significant impact on the transparency of the plastic bag.

      膠袋定做的材質有很多種,而且做法很非常多種,但是有關于OPP的一些詳細參數以及性能,卻鮮有人知,今天偉達包裝就為大家講解一下它的以下一些內容:

      There are many types of materials and methods for customizing plastic bags, but few people know about the detailed parameters and performance of OPP. Today, Weida Packaging will explain the following contents to you:

      塑料PE膠袋材料的主要優勢是質量輕,能夠減少運輸成本和整體供應鏈成本,此外還不易破損。這種新材料能幫助生產商降低碳足跡,減少對石化產品和其他富含礦物質的包裝材料的需求,從而更好地保護環境。塑料PE膠袋領域也越來越青睞輕量化材料,幾乎每一種塑料包裝都在外形和結構上強調這一點。

      The main advantage of plastic PE bag material is its light weight, which can reduce transportation costs and overall supply chain costs. In addition, it is not easily damaged. This new material can help manufacturers reduce their carbon footprint, reduce the demand for petrochemical products and other mineral rich packaging materials, and thus better protect the environment. The field of plastic PE bags is also increasingly favored for lightweight materials, and almost every type of plastic packaging emphasizes this in terms of appearance and structure.
