I'm not sure what your point is here.
The whole point of recycling paper is to avoid cutting down trees (and as a minor secondary point reduce landfill, though most paper is compostable). Paper recycling is quite energy and chemical intensive when compared to virgin paper production. If you want to talk about "sustainable" and consider planting trees to be fine, then you don't want to recycle.
I don't consider cutting down trees and replanting them that great, frankly. You take a large tree with a large surface area that's transpiring lots of carbon and replace it with a sapling with a small surface area. Yes that sapling is, over time, turning carbon into tree trunk, but that time scale for that is decades while the paper releases carbon immediately through its production and transport and then continues to do so over decades as it decomposes.
This calculus can be improved by making the paper out of something with a better yield and shorter growth time (hemp is claimed to be such but I have no idea if that's true) and by using non-fossil fuel. But you have to look at the chemistry required as well...and in any case paper is heavy (a box of paper is basically a box of wood) which is inherently fuel intensive.
Plastic film (and plastic toys) are sequestered if you can stick them in landfills. Of course the best carbon sequestration will be to leave the oil in the ground...not yet an option in 2017.
But the best lifecycle analysis has to be done on base of most accurate costs possible, not emotion. Paper is pretty shitty.
