Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Glycerol, gelatin and CO 2 were used to prepare chitosan-based packaging films with improved mechanical properties and seal strength. Nuclear magnetic resonance spectroscopy, X-ray diffraction analysis, Fourier transform infrared spectroscopy and dynamic mechanical analysis were conducted; the results were used to explain the mechanical and sealing properties data. Film color was also measured. Combined addition of glycerol and use of CO 2 to treat the film-forming solution led to decreased film crystallinity and glass transition temperature, resulting in improved film mechanical properties. Addition of glycerol and gelatin resulted in enhanced molecular interactions between chitosan-gelatin and improved sealability of the films. Films with the best mechanical and sealing properties were obtained from a solution with 25% (w/w) glycerol and treated with CO 2 and from that with 25% (w/w) glycerol and 10% (w/v) gelatin, respectively. Films with addition of both glycerol and gelatin exhibited lower lightness, but higher yellowness than the commercial stretch film.
