Specifically interested in the type of paper used to make carrier bags.

Probably pine or spruce, since these have longer fibres which make for stronger (but coarser) paper, such as you might find in a bag. Check out the link though for all you might need to know!

Interesting question. I would assume some sort of spruce or pine because they both grow quickly, are easier to process than hardwoods like oak or maple, and have a different structure that I would think would be better for making paper. That's a guess though, since it's all pulverized anyway.

Here's an interesting site about paper making:

Paper is made from natural fibers called cellulose. The primary source of cellulose in the U.S. today is wood. Many types of wood can be used to make paper. The two main types are hardwood such as oak, and softwood, such as pine.

Softwood fibers are over twice as long as hardwood fibers. In general, the longer the fiber, the stronger the paper will be. Therefore, softwood fibers are best used for paper or paperboard which requires strength, such as grocery bags and boxes. Short fibers, on the other hand, help make paper smooth. A blend of hardwood and softwood fiber is ideal for making printing and writing paper, which needs to be both strong and smooth.

Probably half of the fiber used for paper today comes from wood that has been purposely harvested. The remaining material comes from wood fiber from sawmills, recycled newspaper, some vegetable matter, and recycled cloth. Coniferous trees, such as spruce and fir, used to be preferred for papermaking because the cellulose fibers in the pulp of these species are longer, therefore making for stronger paper. These trees are called "softwood" by the paper industry. Deciduous trees (leafy trees such as poplar and elm) are called "hardwood." Because of increasing demand for paper, and improvements in pulp processing technology, almost any species of tree can now be harvested for paper.

Cheap paper (computer paper, school paper, etc) is made from fast growing soft woods like pine. Fine, glossy papers (encyclopedia, etc) are made from oak, specifically white oak that grow slower but have longer stronger fibers. Alot of carrier bags are thin paper intertwined with cotton, much like dollar bills.

I think mostly pine or spruce, as above, but in Australia wood chip for paper making is made from hardwood eucalyptus trees. A lot is shipped overseas, and woodchipping is a controversial industry because of the destruction of native forests.

I think pine spruce trees and also oak trees coz i made papers with oak trees and it turned out brilliantly.

Family trees. Mug trees. Lava trees. Tirty trees.

No seriously, teak and mahogany.

It is mostly prepared by tree trunk and leaves also, preferably of eucalyptus tree.
