Instant noodles are probably something everyone has eaten. When we open a pack of instant noodles, a large part of it is empty, which causes the volume of the noodle bucket to increase and occupy more space during stacking. Consequently, the cost during transportation will also increase. Designers have come up with a solution to this problem by designing the instant noodle packaging to be telescopic. When you want to prepare the noodles, you can extend the packaging, and after eating, you can compress the packaging, making it easier to dispose of and allowing trash bins to hold more waste. It's a very clever design.
