With the development of technology, different new materials have also emerged. To make people's daily wealth more convenient and efficient, today we will talk about pearl cotton. Perhaps many friends do not know what pearl cotton is. Today, Guangzhou pearl cotton manufacturers will briefly introduce and describe how to distinguish the quality of pearl cotton.
Pearl cotton, also known as polyethylene foam cotton, is a new type of environmentally friendly packaging material. In the rapid development of express delivery today, we can no longer do without pearl cotton. Compared to those outdated packaging materials, pearl cotton not only has stable chemical functions, but also has strong moisture-proof, anti-corrosion, and shockproof functions. Moreover, pearl cotton also has many advantages and functions such as sound insulation, insulation, strong toughness, and strong plasticity, The most precious thing is that pearl cotton can be reused, and in today's society that values conservation, environmental protection, and green, it is definitely catering to the taste of the public.
Pearl cotton, as a new type of environmentally friendly material, is composed of low-density polyethylene grease through physical foaming, which generates many independent bubbles. Physical foaming overcomes all the shortcomings of ordinary foaming, such as the simple crushing, deformation, and poor health of foam adhesive. Moreover, the chemical properties of pearl cotton are quite unique. Although it also has some plastic properties, pearl cotton has strong degradability. And it can be decomposed appropriately and clean, with relatively low environmental pollution. Due to these physical and chemical properties, pearl cotton has become an ideal alternative to traditional packaging materials.
So how to distinguish the quality of pearl cotton? What kind of pearl cotton can be considered high-quality pearl cotton? Firstly, it is important to note that high-quality pearl cotton rice sprints have a very high density, but the volume of the bubbles is very small. The shape of the team doctor's bubbles should be very uniform and round. Only with such pearl cotton can the elasticity be better and the overall pressure bearing be more uniform. Moreover, high-quality pearl cotton will gradually bounce and recover to its original thickness under heavy pressure, but inferior pearl cotton will not achieve this effect.
Poor quality pearl cotton has a lower density of bubbles and relatively larger bubbles. However, after enduring heavy pressure, pearl cotton with tear stains becomes thinner and the recovery is getting worse. And the physical and chemical properties of inferior pearl cotton will also decrease. The insulation and seismic resistance functions will deteriorate. Below, we will provide a detailed explanation of the methods for determining the quality of pearl cotton.
The first point is the softness of pearl cotton. High quality pearl cotton has a softer texture, as only pearl cotton with strong softness will show more of its high-quality characteristics during use. For example, it can better protect the product throughout the entire transportation process, avoiding damage caused by shaking during transportation.
The second point is the thermal insulation of pearl cotton. Nowadays, many items in daily life are diverse, and many specific products have high temperature requirements during transportation. Due to the excellent thermal insulation and insulation properties of pearl cotton, the quality of pearl cotton also needs to be tested in terms of thermal insulation and insulation. This is also very important.
The third point is the waterproofing of pearl cotton. The quality of pearl cotton can also be judged through the testing of its waterproofing. As any product requires waterproofing during transportation and packaging, there are very high requirements for the waterproofing of pearl cotton. Especially for some products, no water can occupy them during transportation. Therefore, when selecting good pearl cotton, its waterproofing should be tested.

The fourth point is the weight of pearl cotton. In the same volume of pearl cotton, with equal thickness, length, and width, the lighter the pearl cotton, the better its quality. As the lighter the weight, the larger the volume of pearl cotton under equal weight, the better the buffering effect will be.
