Analysis of physical property changes in films due to UV irradiation

Investigating how the light transmittance of blue light cut film changes using a spectrophotometer!

The blue light cut film has the effect of suppressing the transmission of visible light, especially light with wavelengths below 500nm, compared to regular PET film. Using a spectrophotometer, we examined how the light transmission properties of the blue light cut film change under UV irradiation. The transmission of light in the wavelength range of 350 to 400nm further decreased due to UV irradiation. Additionally, we conducted an analysis of the reactions occurring within the film using GC-MS.

We are explaining the changes in transmittance of PET resin and PVC resin using graphs!

Introducing the "Transmittance Measurement Service Using an Automatic Spectrophotometer." The transmittance of transparent materials is an important characteristic item in the specifications of the products used. This characteristic may deteriorate or be lost due to degradation from heat, humidity, ultraviolet light, and other factors. This document includes the principles of the equipment, as well as a comparative evaluation of the changes in transmittance before and after constant temperature and humidity testing of transparent resins, along with discussions on the results. We encourage you to read it.

Here is an example of analyzing the polymer components and additives used in PTP packaging sheets for tablet packaging!

This document introduces the analysis of PTP packaging sheets using EGA-MS analysis and thermal desorption/pyrolysis GC-MS analysis. Various materials are used in industrial products; for example, polymers contain low molecular weight components such as additives and high molecular weight components that are the polymers themselves. In GCMS analysis, low molecular weight components volatilize at relatively low temperatures, while high molecular weight components need to be decomposed at high temperatures before analysis. Here, we present an example of analyzing the polymer and additive components of PTP packaging sheets used for tablets. We invite you to read it.

Based on practical experience in support companies and business companies, SBS Marketing Co., Ltd. provides consulting services related to marketing, sales promotion, and customer acquisition mainly in the BtoB (business-to-business) sector. On September 23, 2025 (Tuesday), they published a page titled "Easier to Optimize the Allocation of Management Resources!? 'Product Portfolio Management (PPM)'". 'Product Portfolio Management' allows for the optimal allocation of management resources by evaluating one's business along two axes: "market growth potential" and "market share," and classifying it into four quadrants. The page explains the benefits that can be realized by utilizing it, the two axes and four quadrants that make it up, and the associated risks. (Page Overview: Excerpts) ■ What is 'Product Portfolio Management'? ■ What can be achieved through 'PPM'? ■ Components of 'PPM' (vertical and horizontal axes) ■ Components of 'PPM' (four quadrants) ■ Two risks associated with 'PPM' (DL content only) ▼ For more details, please visit this page. https://sbsmarketing.co.jp/blog/ppm-2025-09/

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
