High strength holocellulose paper from bamboo as biodegradable packaging tape

As the fast-growing of package business in express delivery industry, replacing traditional scotch tapes with degradable materials has attracted extensive attention. Herein, holocellulose paper (H-paper) was prepared by an efficient delignification and papermaking process from bamboo. The structure and properties of resultant holocellulose fibers and H-paper were characterized and compared with those from other pulping methods, such as Kraft pulping, enzyme treated, sulfite and alkaline sulfite process. The yield of holocellulose pulp (55%) increased by about 10% compared with that of other fibers. Compared to that of Kraft paper (38 MPa), the strength of H-paper increased by nearly 60% at similar density, reaching a maximum of 65 MPa. The total transmittance of H-paper was about 20% higher than Kraft paper. Moreover, H-papers displayed high mechanical properties, good printability, and degradability, which was important for the application as paper tape.
