  1. Food packaging bag density

  The density of food packaging bags is a single molecule of a unit volume and functions for their stacking methods. The entertainment hydride is composed of light atoms, so the general density is low. The density of a polymer of simple hydrocarbons -polyethylene, polypropylene, and polystyrene is 0.9 丨 .ig/cm3. Polyethylene and density with heavier such as fluoride or chlorine atoms can get a density of 1.2 丨 .5g/cm3 with a density of 1.5g/cm3 was 2.1 ~ 2.28/0^polytrafluoroethylene. The density of polydehyde is more density because the C -0 -C keys are built closer. The crystalline polymer is more dense than an amorphous polymer, because the stacking is more dense, so the density is high. The composition, structure and crystallization of the polymer can be reflected through the density.

  2. Food packaging bag transparency

  The transparency of the food packaging bag is through the optical M and the total incident House through the optical M of the object: the ratio, also known as the light transmission, and sometimes it is determined by a certain wavelength range of light. The density difference is required to determine the transparency, because the refractive index is always proportional to the density. If the density of the amks is similar to that of the crystal material, it is slightly scattered when the mixture of the two structures through these two structures, and the material is transparent; on the other hand, when the density difference between the two is very large, it is opaque. In the polyethylene, the density difference is small in a large density difference. However, if the polymer crystal material is quickly cooled, the crystal is very small, so that the polymer crystal is shorter than the wavelength of the light to pass through the light. Materials can be transparent.

  3. Food packaging bag water absorption

  Food packaging bags will be immersed in a certain size (25 feet or 20: T 2 feet 2 feet) of the specified size of the sample. You can also use the unit area of water absorption or water absorption (milligram)
