Siko Co., Ltd. Creates a "Leak-Proof World"!

Siko Co., Ltd. (Headquarters: Osaka, Osaka Prefecture; Representative Director and President: Tadaomi Shiraishi; hereinafter "Siko") supports April Dream, which aims to make April 1st a day for announcing dreams.

This press release is a dream of Siko Co., Ltd.

Siko has been manufacturing and stably supplying industrial packaging materials to the market for over 75 years, with the vision of "A Stress-Free World Created by Packaging - Easy to Use, Easy to Tidy Up, Easy to Produce." Throughout this time, we have pursued the quality of being "leak-proof." In filling sites that handle powders and granules, even a slight leak directly leads to decreased work efficiency, increased cleaning costs, and even quality risks. The performance of bags is not merely a matter of packaging material quality; it is a crucial infrastructure element that supports productivity and safety.

The "leak-proof world" that Siko envisions is a world where waste is eliminated, costs and risks are minimized, and a sustainable production environment is realized for both people and the environment. It is a world free from unnecessary cleaning, protecting the health of workers, and free from stress and burden for everyone involved: those who make, those who use, and those who transport. We aim to eliminate the losses and burdens caused by leaks, which have traditionally been considered "unavoidable," through technology.

Through the quality of being "leak-proof," Siko aims to change the norms of production sites and realize a more efficient, safe, and sustainable society, driven by curiosity, passion, and cultivated technology.

Activities to Create a "Leak-Proof World" by Continuously Pursuing "Leak-Proof" and Never Giving Up on Challenges

Activities of "Leak-Proof LAB": Siko launched "Leak-Proof LAB," an experimental project that disseminates information about people, places, and companies, both internal and external, that explore "leak-proof" solutions, in February 2026. Through this activity, we will conduct multifaceted activities such as media outreach, seminar hosting, on-site tours, and exhibition-linked projects.

Laboratory in Fukushima Factory:

To embody the quality of being "leak-proof," Siko has established its own laboratory within the Fukushima factory. Currently, using actual machines introduced from filling machine manufacturers, we routinely conduct filling tests with various types of powders to achieve "leak-proof" quality. We verify the occurrence of leaks according to powder particle size, specific gravity, and filling conditions, and continuously improve under Siko's unique strict evaluation standards to pursue "leak-proof" quality.

Factory Grand Opening with Drone Footage!:

It has generally been said that knowledge cultivated within companies, factories, and on-site in any industry is kept internal. Especially in the B2B sector, it is often treated as a trade secret, and factory interiors are not disclosed. However, Siko believes that by disseminating its technological background and verification processes, it can contribute to realizing the company's vision of "A Stress-Free World Created by Packaging - Easy to Use, Easy to Tidy Up, Easy to Produce," improving overall industry quality, and boosting the packaging market.

◾️ Comment from Representative Director and President Tadaomi Shiraishi

"It's okay if a little leaks." I genuinely want to eliminate this notion.

However, a "leak-proof world" cannot be achieved solely with the technology of a bag manufacturer. It relies on the power of partner companies such as paper manufacturers and filling machine manufacturers.

That's why Siko will disseminate its initiatives through "Leak-Proof LAB" and factory disclosure via drone footage, connecting with partners who share our vision. This is a concrete means to realize our dream.

It's just right to be told, "Are you going that far?"
Together with such partners, we will create a "leak-proof world."
