What are paper straws coated with？

As we all know that the paper Straw is made of three layers of paper rolled together. But how can three layers of paper be tightly rolled together? This requires a special glue, each layer of paper will be dipped through glue before being rolled. After this treatment, the paper Straw becomes more strong. Better hardness, better water resistance properties.

As paper straws need to be food grade, the glue used on paper straws also needs to be rigorously tested before it is allowed to be used. The chemical name of the glue, known as White Latex, requires MSDS testing before it can be certified to use.

Different quality of glue, different cost. However, this is very hard to be distinguished from the appearance of paper Straw on the market.  That explained many straw manufacturers quoted particularly cheap, use of a different quality of glue, may be an important reason.

Therefore, when you choose suppliers, be sure to choose standardized large factories to cooperate, because they will spend a lot of time and cost in places you can not see. Sometimes, these invisible details, determine the stability of the quality, determine how long the business will last.
