How to judge the quality of pearl cotton through these methods

Pearl cotton, also called polyethylene foamed cotton, is a new type of environmentally friendly packaging material. Today, with the rapid development of express delivery, we can no longer do without pearl cotton. Compared with those backward packaging materials, pearl cotton not only has stable chemical properties, And it has strong moisture-proof, anti-corrosion and shock-proof functions. Not only that, pearl cotton also has many advantages and properties such as sound insulation, heat preservation, strong toughness, strong plasticity, etc. The most precious thing is that pearl cotton can be reused. When paying attention to conservation, Today's environmentally friendly and green society definitely caters to the public's taste.

As a new type of environmentally friendly material, pearl cotton is made of low-density polyethylene grease that is physically foamed to produce countless independent bubbles. Physical foaming overcomes all the shortcomings of ordinary foaming, such as Foam rubber is easily broken, deformed, and has poor recovery properties. Not only that, the chemical properties of pearl cotton are also quite special. Although it also has some properties of plastic, pearl cotton is highly degradable. And it can be decomposed quite cleanly, causing relatively low environmental pollution. Because of these physical and chemical properties, pearl cotton is an ideal substitute for traditional packaging materials.

So how to distinguish the good and bad pearl cotton? What kind of pearl cotton is considered to be high-quality pearl cotton? The first thing to look at is that the density of good-quality pearl cotton rice is very high, but the volume of the bubbles is very small. The shape of the bubbles must be very uniform and relatively round. Only such pearl cotton, The elasticity will be better, and the overall pressure-bearing capacity will be more uniform. Moreover, better-quality pearl cotton will slowly bounce back to its original thickness after being subjected to heavy pressure, but inferior pearl cotton will not achieve such an effect.

The bubble density of inferior quality pearl cotton will be smaller, and the bubbles will be relatively larger. However, after withstanding heavy pressure, the tear mole pearl cotton will become thinner and thinner, and recovery will become increasingly difficult. good. Moreover, the corresponding physical and chemical properties of inferior pearl cotton will also become lower. Thermal insulation and earthquake resistance properties will deteriorate. Below we will explain in more detail the specific methods of the quality of pearl cotton.

The first point is the softness of pearl cotton. The texture of pearl cotton with higher quality will be softer, because only pearl cotton with stronger softness will show more of its high-quality characteristics during use, such as in The product can be better protected during the entire transportation process, preventing the product from being damaged due to shaking during transportation.

The second point is the heat insulation of pearl cotton. There are many kinds of items in life now, and many specific products have very high temperature requirements during transportation. Due to the characteristics of pearl cotton, it has good heat insulation. And thermal insulation, so the quality of pearl cotton must also be tested in terms of thermal insulation and thermal insulation. This is also very important.

The third point is the waterproofness of pearl cotton. To judge the quality of pearl cotton, you can also test the waterproofness of pearl cotton, because no matter what the product is, it needs to be waterproof during transportation and packaging, so for the waterproofness of pearl cotton Water resistance has very high requirements, especially for some products, which cannot absorb any water during transportation. Therefore, when purchasing good pearl cotton, you must test its waterproofness.

The fourth point is the weight of pearl cotton. For the same volume of pearl cotton, the same thickness, length and width, the lighter the pearl cotton, the better the quality. Because the lighter the pearl cotton, the larger the volume of the pearl cotton at the same weight, the smaller the volume. The larger the size, the better the buffering effect will be.
