A Brief Discussion on Some Precautions Regarding the Thickness of Plastic Packaging Bags

First of all, currently, we generally use "silk" to represent the thickness unit of plastic packaging bags. 1 millimeter (mm) =100 silk. Logically, everyone should express it in mm. However, since people are accustomed to using "silk" in daily production and life, the quotations of plastic packaging bag manufacturers are also based on "silk". Under normal circumstances, different bags have different thicknesses. 10 microns means the bag is 0.1 millimeters thick, and 8 microns means the bag is 0.08 millimeters thick. Now that we know this point, we can talk about the thickness of plastic packaging bags from the perspective of data.

The thickness of plastic packaging bags is a key point in determining whether a plastic packaging bag is environmentally friendly and made of degradable materials. According to the national plastic restriction order, plastic shopping bags should reach 0.025mm(single-layer film) or more. Bags with a thickness above this limit are called environmentally friendly plastic bags. Therefore, the composite plastic packaging bags generally used for product outer packaging can be trusted in terms of environmental protection.

Second, the thickness of composite plastic packaging bags should be determined by the thickness of the bag itself. This is because composite plastic packaging bags are composed of several layers of film, and some plastic packaging bags are also made of high-quality or non-woven fabrics and other materials. Therefore, the thickness of the bag cannot be judged by the thickness of just one material.

Third, plastic packaging bags are not necessarily the thicker the better. We say that only the appropriate and reasonable ones are good. Because many customers insist on using thick plastic packaging bags when customizing them, in fact, plastic packaging bags of different thicknesses correspond to different strengths, and different products have different requirements for the strength of packaging bags. It is good to make a reasonable choice. As a manufacturer of plastic packaging bags, based on years of production experience, we have a general standard for what thickness of plastic packaging bags should be used for most common products. Before customizing plastic packaging bags, communicating more with the manufacturer will make it easier for you to choose the appropriate plastic packaging bags.

Fourth, there is one more point to note. When we talk about the thickness of plastic packaging bags, there are two expressions: one is the single-sided thickness, and the other is the double-sided thickness. In fact, these two expressions indicate that the thickness of the plastic packaging bags is consistent. The single-layer thickness is half of the double-layer thickness value.
