Repulpability test for impurity removal by pulping equipment : The film removal test(hole/slot/flotation reject) with PE-, PLA-, and RP-coated cups confirmed the outstanding repulpability of rePAPER’s coatings.

A research report about rePAPER’s recyclability was published in Nordic Pulp & Paper Research Journal
(SCI level)in March, 2017.
Verification of rePAPER’s recyclability at a domestic paper manufacturer
: The dissociation rate reached over 98% after 20 ~ 40 min. of repulping at 40℃ and the pulp was entirely used for recycled-paper manufacturing.
→ Recyclability proven.

• 3# Pulper 10'Pulping Test
* Though 40 min. shows the highest dissociation rate, 20 minutes of repulping seems to be enough. • Lab Mill Test

| Conclusion | It took less time to repulp the scrap paper of rePAPER’s products and the yield was shown to be much better compared to conventional DLK. Furthermore, acrylate-based coatings left no residuals after additional treatment. Hence, it seems possible to use the recycled pulp as raw material. | ||||||||||||||||||||||||||||||||||||||||||||||
