Kewpie's New Caps for Mayonnaise: Innovative Design Reduces Plastic Waste

Kewpie's Innovative Lightweight Mayonnaise Caps

Kewpie Corporation, based in Shibuya, Tokyo, has announced a new lightweight cap for its iconic Kewpie Mayonnaise, specifically the 700g bottle. Leveraging decades of experience in container and packaging development, the company has achieved a remarkable 17% reduction in weight for the new cap, cutting it down from approximately 5.2 grams to roughly 4.3 grams. The switch to these new caps is slated to begin in mid-November 2025, marking this as a significant milestone amid the brand's 100th anniversary celebration.

A Step Toward Sustainability

This initiative is a part of Kewpie's ongoing commitment to environmental responsibility. The reduction in plastic usage translates to approximately 3.4 tons of plastic savings annually, based on last year's shipping figures. This new cap development is pivotal for Kewpie as it reflects the company's dedication to minimizing environmental impact while enhancing user experience.

Over the years, Kewpie has made considerable efforts towards environmentally friendly packaging solutions. Back in 2000, they introduced a lighter poly bottle, achieving around a 15% reduction in weight. The current double-cap system in use since 2005 features two functionalities but has been subject to redesign to ensure that less plastic is utilized.

The lightweight cap will play a critical role as it constitutes about 20% of the entire plastic usage in the mayonnaise container, indicating its potential impact on overall plastic reduction. With the introduction of this new cap design, Kewpie is not just keeping an eye on sustainability but also enhancing the usability of their products.

Design Adjustments without Compromising Usability

In creating the new cap, Kewpie has focused on keeping its user-friendliness intact. Adjustments have been made meticulously to ensure that customers find the cap just as easy to use as its predecessor. The redesigned cap features a 3.9mm reduction in height, aimed at reducing slippage during opening and closing. The textured surface area has been reduced to further enhance grip without compromising comfort.

Historically, the existing cap featured a high spout designed to prevent drips; however, it added to the plastic content. The new lightweight cap has shifted the spout's position, lowering it without sacrificing functionality. This tailored design minimizes spillage while maintaining the aesthetics and performance that Kewpie users expect.

In alignment with its sustainability goals, Kewpie Group aims to reduce plastic waste by at least 30% by the fiscal year 2030 compared to 2018 levels. With the estimated reduction of approximately 3.4 tons of plastic and a CO2 emission reduction of about 13 tons projected from this initiative, Kewpie takes definitive steps toward a more sustainable future.
