  1. PLA is generally used to produce plastic-free paper cups, but the high cost of raw materials leads to relatively high product prices. PLA has relatively high requirements for production technology. If the technology is not handled properly, there will be delamination, which will affect the quality. Plastic-free paper cups and ordinary paper cups look no different in appearance. Ignite the two paper cups separately with fire. The ordinary paper cup will emit some black smoke with a slight plastic smell, while the plastic-free paper cup smells no peculiar smell, and the burning smell is the same as that of ordinary paper. Plastic-free paper cups also have a shorter degradation time under natural conditions, and both water-based coatings and paper can achieve full biodegradation. As a paper cup manufacturer, Zhejiang Pando EP Technology Co., Ltd. is committed to the development of global plastic reduction and environmental protection, aiming to promote green and sustainable packaging.

  2. Take out two identical recyclable paper cups, pour 75% ethanol disinfectant and white wine into two paper cups, and observe the changes in the paper cups. Ten minutes later, you can see that the outside of the paper cup with alcohol turned red, and the bottom and seams of the paper cup with white wine turned dark yellow. What has actually happened? It turns out that the pattern printed on the paper cup is made of ethanol ink, which is also an environmentally friendly ink, so the color will fade when it touches alcohol. Because the purity of pure alcohol is relatively high, the environmentally friendly ink on the outside of the paper cup is physically dissolved, so it turns red. When using paper cups to pack white wine, the alcohol concentration is not so high, so the final residue is pale yellow. So, will this kind of discolored paper cups have an impact on the health of the body? In fact, environmentally friendly ink is an organic solvent. Use disposable paper cups for alcohol and beverages. Long-term use will affect the human brain and nervous system and cause certain damage to the body. Therefore, we recommend that you do not use paper cups for alcohol and beverages. If you must use them, try not to use them repeatedly. In addition to the choice of cup material, the quality of paper cups also requires attention. For paper cups whose mouth is within 15 mm from the cup body and the bottom of the cup is within 10 mm from the cup body, it is best not to use paper cups with printed patterns. This is to prevent the ink from entering the mouth and also to prevent the ink from contaminating the inner wall of the cup when the cup is stacked. As a paper cup manufacturer, Zhejiang Pando EP Technology Co., Ltd. reminds you again that it is best to use glass or other material cups when drinking, so as not to cause harm to your body.
