It could be an IPN/composite hydrogel of two bio-polymers as well as for example gelatin and silk. Strength should be reported when it is in hydrated form and not dry strength. Please also provide values in MPa or KPa and reference if any.
Hello Rizwan,
I think the paper in the link bellow is very good giving you numbers of the actually limits of biopolymer based hydrogels. It is a paper focus on amyloid materials (the area I also work on) but it has interesting graph in Figure 3 with "Mechanical properties of amyloid fibrils in comparison to biological and inorganic or non-biological materials". And it has really good values of several biopolymers and references of those.
Paper is:

See the work and publications of Prof. Jian Ping Gong and her group at U Hokkaido on double network hydrogels. They have developed remarkably strong and tough gels in which at least one of the network components is a biopolymer. I have also posted some papers on RG on this topic which I co-authored with her.
