AI Technical Summary

Technical Problem

Conventional roll-type paper towel packaging faces challenges in achieving a core outer diameter within a certain range, ensuring good packaging properties, aesthetic appeal, and ease of use, particularly when incorporating high-basis-weight paper towels containing synthetic fibers.

Method used

The packaging is designed with specific parameters for the basis weight of paper towels, core outer diameter, cross-sectional area, winding diameter, roll density, and thickness of the packaging film within predetermined numerical ranges, including a core outer diameter of 25 mm to 55 mm, a cross-sectional area of 30 cm² to 190 cm², a roll density of 0.05 g/cm³ to 0.19 g/cm³, and a packaging film thickness of 20 μm to 55 μm, to create a roll-shaped paper towel package that is easy to use and aesthetically appealing.

Benefits of technology

The solution results in a roll-shaped paper towel package that maintains a core outer diameter within a certain range, providing good packaging properties and aesthetic appeal while being user-friendly, addressing the limitations of conventional packaging.
