胶袋与PE胶袋有什么区别?
发布于:2024/02/06

胶袋、PO胶袋都是透明的,感到有所疑虑,今天胶袋厂就为大家一一讲解。在使用中的胶袋为什么都会是透明的,这主要是因为任何晶体型开口剂对胶袋的透明度都有一定的负面影响,即会在薄膜内形成一种雾气。但因产品使用的开口剂品种不同,影响程度也会有所不同,然而影响胶袋透明度的因素主要有以下几点:

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:

开口剂的化学纯度。化学合成晶体的纯度远高于天然矿物。因此,由化学合成工艺制造的开口剂,其透明度明显高于天然矿物。

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.

开口剂的加入量。晶体型开口剂因来源不同,其中重质晶体是指天然矿物类开口剂,另一种是轻质晶体是指由化学合成的开口剂。两者之区别在于,在相同体积下,重量有明显的差别。

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.

开口剂的光折射率。直射光穿越两种不同物质的接触界面时,如果两种不同物质具有相同的折射率,则穿越的直射光在原入射角的线向范围内损失小。如果两种不同物质的折射率相差越大,则穿越的直射光在原入射角的线向范围内损失越大。因此天然滑石粉、二氧化硅均对直射光造成较大的衰减,对胶袋的透明度有明显的影响。

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.

胶袋定做的材质有很多种,而且做法很非常多种,但是有关于OPP的一些详细参数以及性能,却鲜有人知,今天伟达包装就为大家讲解一下它的以下一些内容:

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胶袋材料的主要优势是质量轻,能够减少运输成本和整体供应链成本,此外还不易破损。这种新材料能帮助生产商降低碳足迹,减少对石化产品和其他富含矿物质的包装材料的需求,从而更好地保护环境。塑料PE胶袋领域也越来越青睐轻量化材料,几乎每一种塑料包装都在外形和结构上强调这一点。

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.
