Despite its many advantages, bagasse packaging does have some limitations. It is not suitable for products that require airtight packaging, as it is not completely waterproof. It also has a limited shelf life and can begin to break down if exposed to moisture for extended periods of time.

The disadvantages of bagasse packaging mainly include the following aspects:

1.Poor Physical Performance: The strength of bagasse packaging is relatively low, with mechanical strength indicators such as tensile strength and tear strength being relatively weak. In daily use, it is prone to breaking or tearing, especially when binding books or packing heavier items, as its ability to withstand external forces is limited.

2.Poor Optical Performance: The whiteness of bagasse is relatively low, and even after bleaching, it is difficult to achieve the high whiteness of wood pulp paper. The lower whiteness limits its application in areas requiring high paper whiteness, such as high-end printing products and office paper.

Additionally, the surface of bagasse paper is relatively rough, and the fiber distribution is uneven, leading to poor glossiness and inferior printing results compared to wood pulp paper.

3.Limitations in Processing Performance: The complex structure of bagasse, including lignin and other components, affects fiber separation and processing. Special treatment methods are required during the papermaking process to remove lignin and other impurities, increasing the complexity and cost of production.

Furthermore, bagasse is greatly affected by humidity and temperature, making it prone to deformation and expansion, which results in poor dimensional stability of the paper.

Despite these drawbacks, bagasse packaging materials also have unique advantages:

1. Biodegradability: Bagasse fibers can biodegrade within 30 to 90 days, ensuring that the packaging decomposes naturally over time. In commercial composting facilities, post-consumer bagasse boxes can decompose even faster, reportedly in as little as 60 days.
2. Environmental Friendliness: Bagasse packaging materials can fully degrade in natural conditions within 90 days, with the primary byproducts being water and carbon dioxide, leaving no residual waste or pollution.

In contrast, non-degradable plastic utensils produce large amounts of harmful substances, polluting the environment and posing risks to human health.
