Given the consistently high consumption of paper cups and the massive daily output from manufacturing machines, proper storage is essential to maintain quality.
1. Paper cups must be packed in cardboard boxes; leaving them loose exposes them to yellowing and moisture.
2. Cups should be placed in dedicated plastic bags that are tightly sealed; exposure to air can cause the paper to yellow.
3. Store cups in a dry area to prevent moisture damage, and ensure the cardboard boxes are securely sealed with tape.
4. The typical shelf life is one to two years (provided they are properly packaged); otherwise, it is generally six months.
