And now for some sad news: Bubble wrap, the packaging material popular with shippers and toddlers alike, is losing its pop.

According to a July 1 article in the The Wall Street Journal, Sealed Air Corp., the original seller of bubble wrap since 1960, is rolling out a revamped version of its signature product. Dubbed iBubble Wrap, the new packaging is sold in flat plastic sheets that shippers fill with air using a custom-made pump. The inflated bubbles look much like traditional bubble wrap, with one key difference — they don’t burst when pressure (or stomping) is applied.

Why the change? It’s all about space, according to the WSJ article. Traditional bubble wrap ships in giant, pre-inflated rolls that occupy precious room in delivery trucks and on retailers’ warehouse floors. One roll of the new iBubble Wrap, on the other hand, uses roughly one-fiftieth as much space before it’s inflated. Sealed Air believes the new wrap will appeal to online retailers that are driving growth in the $20 billion protective packaging business and want to ship items as compactly as possible.

Sure, there’s a logical business rationale for Sealed Air’s decision, but that doesn’t mean my kids — alright, me too — won’t be disappointed when the change takes place later this year. The therapeutic sensation of popping the original bubble wrap has lead to its unorthodox use as a stress-relief tool, spawning a range of unofficial novelty products including calendars, clothing and iPhone cases.

With no more bubbles to pop, how will I get my aggression out? Any suggestions?
