Stretch film is essential in logistics and manufacturing sites. However, many companies face challenges such as "which thickness should be chosen," "what is the difference between hand-wrapping and machine-wrapping," and "is there a way to reduce costs while maintaining quality?" This document clearly explains the basic structure of commercial stretch film, the characteristics of raw materials, the mechanism of multilayer structures, and manufacturing methods such as cast and inflation methods. Additionally, it provides detailed information on selection criteria based on applications, usage methods that lead to improved logistics quality, and key points for cost reduction through thinner films and pre-stretching. Proper selection of stretch film not only prevents load shifting but also directly contributes to reducing packaging costs, improving work efficiency, and lowering environmental impact. This is a practical guide that compiles useful know-how for improving logistics and manufacturing sites.

Aren't you just ending it with "that was close"? It is said that many serious accidents in factories occur after numerous near-miss incidents. This document carefully selects and introduces examples of near-miss incidents commonly seen in manufacturing sites such as machining, sheet metal processing, assembly, logistics, and equipment maintenance. It clearly explains possible incidents and countermeasures that can occur in actual workplaces, making it useful as safety education material. We encourage you to download it and use it to enhance or review the basics of your company's safety activities. There are two versions available (Japanese and English): - Basic Safety Course: Your "near-miss" can save your colleagues — The first step to accident prevention learned from near-miss incidents — - Basic Safety Course: Your "near-miss" can save your colleagues — The first step to accident prevention learned from near-miss incidents — (English version) *This document is created with general manufacturing industry labor safety and environment in mind. *For specific individual cases or special environments, please confirm with your labor safety officer or internal labor safety committee before use.

After the cherry blossom viewing, the rainy season begins, and before you know it, summer arrives. This summer is also predicted to be extremely hot. Just the other day, our company shipped about 1,500 heatstroke prevention devices to a certain local government. Last year, measures against heatstroke became mandatory, so please consider your options before various products become scarce this year. As the primary distributor for Trusco Nakayama Co., Ltd., we offer a variety of products at reasonable prices. Please feel free to contact us. Koyama Co., Ltd.

Hello. This is Hayashi from Koyama Co., Ltd. Today, I would like to introduce the "Comprehensive Recommended Ranking of Heat Dissipation Items" that can help with thermal management of electronic devices! 1. Thermal Pads / Thermal Sheets ... Overall Rating: ★★★★★ (High ease of use, cost performance, and versatility) ● Advantages: A wide variety of thicknesses / Insulating and flexible, does not damage circuit boards or chips / Suitable for filling gaps between heat sinks and components / Easy to use, even for beginners, just by applying it. ● Suitable Applications / Overall Review Memory / VRAM / M.2 SSD / Power ICs / Driver ICs / General small devices The most versatile and least likely to fail, a universal type. 2. Heat Sinks & Cooling Fans ... Overall Rating: ★★★★☆ (High effectiveness but requires installation space and secure mounting) ● Advantages: Physically dissipates heat to the outside air, resulting in high cooling performance / Fin structure provides a large surface area, enhancing heat dissipation / When combined with fans, it exhibits even higher cooling performance. ● Suitable Applications / Overall Review High-power ICs / LED boards / CPUs / GPUs / High-heat modules The strongest cooling method when space can be secured and mounted. However, since securing installation space and mounting is a prerequisite, the environments in which it can be used are limited.
