How to measure the total thickness of spouted doypacks?
The total thickness of spouted doypacks is an important factor to consider when evaluating the quality and durability of the packaging. In order to understand the total thickness of spouted doypacks, it is essential to consider the material structure and the method for measuring the thickness.
Spouted doypacks are composed of various materials, including printing ink, lamination adhesive, and solvent. The total thickness is the sum of these different materials, as well as the thickness of the individual layers. In order to measure the total thickness of a stand-up doypack, a specific method can be used.
Firstly, the double face thickness of the doypack can be measured using a caliper. This measurement is then divided by 2 to obtain the single face thickness. Additionally, certain materials such as PET, AL, Nylon, and Metalized-PET have fixed thicknesses, which should be taken into account when calculating the total thickness. The remaining thickness is attributed to the contact layer.
For example, if we take a sample of a doypack with spout, the total thickness can be calculated as follows: PET (12micron), AL (7micron), Nylon (15micron), adhesive and solvent (6micron), LLDPE (75micron), resulting in a total thickness of 115micron.
In conclusion, the total thickness of spouted doypacks is determined by the combination of various materials and layers, as well as the printing ink, lamination adhesive, and solvent. By using a specific method for measurement, it is possible to accurately determine the total thickness of stand up doypacks. This information is crucial for understanding the quality and performance of the packaging, and for making informed decisions about its use.
