And jumping in on the digital automation, again as we said, we will talk more about this in future calls, but let me just hit a couple of those highlight points to you, the things that we already started discussing in the last quarters. So first one on automation, so if you think about our business, where we build strength is where we have superior materials, technology to offer to our customers, accompanied by strong automation solutions as well as service. And that's been the driver.
And we mentioned at the last call that a big -- where we have gaps in that portfolio is in a couple of areas. One, if you think on the Protective side, we've announced partnerships around getting the 3D right box solution. And we are starting to get some gains from that partnership. Second, we announced recently in one part of our rollstock portfolio, where we've announced a partnership around trays and overwrap. And we are working there with more partnerships to come to complete that offering.
But also on the fluid side, the Liquibox automation sales are a very small percentage in terms of the overall portfolio. And there, we're working on a couple of partnerships, which we hope to announce in the next couple of quarters, around being able to offer full automation solutions. So again, if you think about it, our approach to the market is superior materials, automation, accompanied with service.
Then jumping in on digital, again two pieces there that we're going to be exploring further in the next upcoming calls. One is on the digital commerce. So today, we have about 22% of our sales that are going through that channel. And as we talked in the past, we pivoted from just continuing to investing in more capabilities in terms of using the investments we've made to drive into commercial success both from the top and bottom line.
And then the second piece that we've talked about, which will come to market in the back half of the year is around our digital printing technology, where we're introducing for flexible shrinkable materials, the first commercial-scale digital printing capabilities with water-based inks. So again, more to come, but those are two key pillars in terms of our growth strategies.
