How to tell cellophane from plastic? If we don't know about cellophane, we might think it is the same as plastic, but their molecular structure and performance characteristics are different.
But how to tell cellophane from plastic? Below we will introduce several methods for you.
1. Look at the color. Cellophane will have different colors, but it must be transparent and will not appear faded. From the appearance, the cellophane is even and soft, and there is no color difference.
2. Smell. Cellophane is a non-toxic and odorless packaging film. Air, oil, bacteria and water are not easy to pass through cellophane, so it can be used for food packaging.
3. Cellophane has strong resistance to oily, alkaline and organic solvents, the transparency is high and the gloss is strong. The color after printing is particularly bright, and other plastic films cannot achieve this effect. When purchasing, you can ask the sales person if the material has these functions.
4. Test. Cellophane is hydrophilic, can absorb moisture, and will adhere after water. When it is hot, the film are easily bonded into blocks. This method can be used to test whether the packaging film is cellophane.
In addition to the above methods, you can also distinguish it from plastic by the function of cellophane.
1. The longitudinal strength of the cellophane is large, the transverse strength is small, the tearing degree is poor, and a slight crack is broken.
2. Because cellophane is made of natural fiber, it does not generate static electricity and does not absorb dust.
3. It has the properties of moisture proof, impervious to water, airtight, heat sealable and so on.
In addition, if you want to buy cellophane, in order to avoid mistakes when buying, please buy at regular manufacturers. And as one of the cellophane film manufacturer, we are happy to provide this service to everyone.
