The Strength and Compressive Strength of Paper Straws

2022-10-28

The problem with paper straws is that they are not biodegradable. Most restaurants do not have compost bins, so these straws will just end up in a landfill. Landfills do not allow for organic material to decompose. That means they will sit in the trash for many years. In addition, paper straws come from trees, so cutting them down requires a lot of energy. Trees must be cut down and transported to factories, where they are pulped and made into straws. Then, the straws need to be packed, shipped, and then disposed of. In addition, this process requires fossil fuels, which will not be renewable in the future.

Paper straws are often made from three layers of paper, with an outer layer made of 60gsm. However, the process can be customized to suit a customer's specifications. The first step in producing paper straws is choosing the paper and adhesive. These two characteristics have a fundamental impact on how the straw performs.

Paper straws are strong, but not flexible. Under humid conditions, paper straws lose up to 80% of their compressive strength in 30 minutes, and in some cases up to 90%.

Using a contact angle analyzer is a common way to measure the hydrophobicity of a paper straw compared to a plastic straw. A high contact angle is a sign of a hydrophobic surface. The larger the angle, the more hydrophobic the straw. Similarly, a low contact angle means a paper straw absorbs more liquid.

Paper straws can impart a cardboard-like taste to your drink. This means they can't impart a rich taste to your beverage. In addition to the paper-like taste, many people also notice a chemical taste in their drink. So, while paper straws can be a great alternative to plastic straws, they are not a satisfactory substitute.
