How To Store And Choose Disposable Double-Layer Paper Cups?

Double-walled paper cups are made by mechanically processing and gluing together paper (white cardboard) made from chemical wood pulp. They appear cup-shaped. Wax-coated corrugated paper cups for frozen foods are suitable for holding ice cream, jam, butter, and more. Double-walled paper cups for hot drinks are coated with plastic and are heat-resistant over 90°C and can even hold boiling water. Disposable paper cups are safe, hygienic, lightweight, and convenient. They are used in public places, restaurants, and are disposable items. Everyone uses disposable paper cups, but do you know how to store them? Don't just leave them lying around when not in use. Hollow Paper Cup explains how to store and select disposable double-walled paper cups.

I. How to store disposable double-layer paper cups.

1. Double-layer paper cups must be packed and cannot be scattered outside, otherwise they will turn yellow and get damp.

2. The openings of each bag of paper cups should be tightly closed to prevent air leakage, which will also cause the corrugated paper cups to turn yellow.

3. Disposable paper cups should be placed in a dry place to prevent moisture, and the carton should be well glued and must be taped.

4. The shelf life of advertising paper cups is generally 1 to 2 years (provided they are well packaged), otherwise it is generally half a year.

[First, Check] The packaging for complete information, including the production license number and QS mark. A good Shenzhen paper cup should have clear, evenly colored, and no visible color spots. A qualified paper cup should have no printed design within 15mm of the cup's rim and 10mm of the cup's bottom.

[Second, Press] Gently squeeze the sides of a hollow paper cup to get a rough idea of its quality. Generally, a high-quality paper cup can hold water for 72 hours without leaking, while a low-quality one will leak within half an hour.

[Third, Smell] Smell the double-layer paper cup to see if there is any pungent smell, especially the smell of ink or mold. Generally, do not buy it if the smell is strong.
