昭和丸筒 Company Overview

A comprehensive package manufacturer that supports people's lives.

Showa Marutatsu Co., Ltd. is a long-established comprehensive packaging manufacturer that celebrated its 100th anniversary in November 2023. We develop products in categories including "paper tubes," "paper and plastic cores," "transport packaging," and "containers," with a focus on the manufacturing technology of "paper tubes." Among these, our "transport packaging" includes a wide range of products that can be proposed to both new and existing customers. We specialize in packaging design that combines primarily paper components to create lightweight, strong, and easily disposable solutions. We offer unique proposals that reflect our long-standing paper tube manufacturing technology, such as paper pallets made with paper tubes that have excellent axial compression strength. Since our products are mainly composed of "paper tube base paper," they possess strengths not found in regular cardboard, making them less susceptible to humidity. Most of our paper products are made from 100% recycled paper, allowing them to be disposed of as paper waste after use and return to paper form. We will continue to develop environmentally friendly packaging in the future.

Business Activities

Manufacturing and sales of paper tubes and plastic cores, paper transport packaging, containers, resin molded products, and Zebro (heat dissipation materials).

We exhibited at the 2nd Power Device & Module Expo!

  • OTHER

From January 22 to 24, 2025, we exhibited at the "Nepcon Japan Power Device & Module EXPO" held at Tokyo Big Sight. At this exhibition, we introduced our vertically oriented high thermal conductivity TIM, "Zebro," focusing on its features. Zebro is a highly durable material that does not suffer from characteristic degradation due to pump-out or dry-out phenomena. It can be used for long periods while maintaining a stable low thermal resistance, making it a reliable heat dissipation material. With the increase in heat generation due to improved semiconductor performance and the miniaturization of devices, the efficiency of thermal management has become a significant challenge. Zebro can be utilized in applications that efficiently dissipate and cool heat generated by electronic components such as power semiconductors supplying high current and high voltage, as well as high-brightness and high-output LEDs/LDs. For those seeking TIMs with good thermal conductivity or facing challenges with insufficient cooling from conventional heat dissipation materials, we offer a variety of thermal management solutions tailored to meet your needs, in addition to Zebro. If you are interested, please feel free to contact us.
