Biodegradability Testing
We strive on protecting the environment — All paper straws from RainbowBear are proven biodegradable in soil and sea. It is reported in our experiment that our paper straws made of environmentally friendly material can be fully degraded within 3 months.
14th Day
The paper straw was still in good condition.
40th Day
90th Day
It was totally degraded in the soil.
Size-to-Spec
We keep every piece of paper straw is in strict compliance with the specification of your order.
You are sure to get the right size of products — We carefully check the sizes using micrometer calipers.
For 1 More Hour Sipping
We pay special attention to the service life of paper straws. Using the UV Dryer, the paper straws are dried up and cohered tightly.
It is a significant step that makes our paper straws stand out by featuring 1 more hours of service life compared to the others.
Visual Inspection
When the paper straws are finished by the machines, we will inspect them to check if there are flaws.
Upon thoroughly examining the seam and shape, we will remove the imperfect straws before final packaging.
Color Examination
To ensure that the finished paper straws are consistent with the specifications of your order, we will examine the products using the originally designed styles.
By doing so, we are confident that neither color deviation nor style mistake will occur.
Soaking Testing
We put the paper straws into different kinds of liquids to test their functioning time.
The testing result shows that our paper straws will not get soggy or disintegrated within 3 hours.
We are so proud to say that our paper straws do not fall apart for even 24 hours.
