Study and data description

The purpose of this work was to investigate water vapor permeation through a layered structure composing of liner and fluting paperboard materials. The layered structure with paperboards separated with ring spacers was used to simulate the structure of a double-wall cardboard.

This dataset contains MRI measurements (RARE pulse sequence) of simulated cardboard assemblies with different fluting materials (Fluting A,B,C) under high humidity. Furthermore, temperature and relative humidity data for possible pre-treatment (in .MAT files) are included.

Included folders and files in the paperboard_zenodo_repository.zip are:

prep_paperboard: Temperature and relative humidity of the pre-treatment for simulated cardboard as .MAT files (can be opened with MATLAB). Two ,MAT-files are included: '14102021_paperboard_flutingCa_nacl_mgcl_RH_t.mat' and '09122021_paperboard_nacl_flutingAB_RH_t.mat'. In the .MAT file regarding Fluting A and Fluting B pre-treated with NaCl (09122021_paperboard_nacl_flutingAB_RH_t.mat) Fluting A is designated as x1NaCl and Fluting B as x2NaCl.

MRI_paperboard: Contains the MRI data as 'fid' and '2dseq' as well as metadata for each experiment obtained at 11.7 T (Bruker)
