Announcement of Prince Eftex's participation in "JAPAN PACK 2025" (October 7th (Tuesday) to October 10th (Friday), 2025)

It is a non-fluorinated oil-resistant paper that does not use organic fluorine compounds (PFAS).

Thanks to the coating technology of the Prince Group, oil resistance has been achieved with paper materials. It is a "non-fluorinated oil-resistant paper" that does not use organic fluorine compounds (PFAS), which raise concerns about their impact on the environment and health.

• Paper and pulp

Paper barrier material that allows visibility of the contents.

This is a paper packaging material that incorporates a function to make the contents visible, in addition to barrier properties and heat sealability. It is ideal for packaging food and daily necessities that you want to showcase. (Patent No. 6930649)

• Paper and pulp

Paper packaging material that does not require a sealant.

It is a paper packaging material specialized for easy heat sealing without the need for a sealant. It is ideal for secondary food packaging, shipping packaging, and industrial material packaging.

• Paper and pulp

For deep-drawn containers, cutlery, hangers, etc.

This is a press-formed paper developed as a plastic alternative, made from wood pulp. It is recyclable and also biodegradable. It can be used for printing and food applications. In addition to deep-drawn containers, it is expected to be utilized in various everyday items such as cutlery and hangers. For more details, please download the catalog or feel free to contact us.

We would like to express our congratulations on the continued prosperity of your esteemed company. Our company will be exhibiting at the following trade show, where we will be showcasing a number of products, including our new product, the Packaging Container Air Leak Test (Pin Hole Inspection) Device | MSQ-2003 series. We sincerely apologize for the inconvenience during your busy schedule, but we would like to cordially invite you to attend this event. 【 Trade Show Name 】 【 Dates 】 【 Venue/Booth Number 】

In this seminar, you will learn the following: - The mixing mechanism and examples of Awatori Nentaro - Stirring methods and heat generation countermeasures according to material viscosity - The latest automation models and syringe filling technology using Awatori Nentaro We will provide not only the basic information about Awatori Nentaro but also the latest updates. During the live demonstration, we will clearly explain how actual materials are mixed and the operation screen of the temperature management solution app for Shinky. Additionally, equipment and optional items will be displayed in the venue, allowing you to consult while viewing the actual products. Please register early!

An explanation of the "detailed risk assessment of hazardous areas," which is essential as the first step in promoting "smart security" and "DX transformation" in hazardous material facilities. We will clearly convey the evaluation methods and points to consider in implementation, incorporating comparisons of old and new evaluation methods as well as recent case studies. There will also be a Q&A session on the day. If you have any questions in advance, please fill them out in the participation input form. You are also welcome to ask questions on the day! We look forward to your participation. Date and Time: October 16, 2026 (Friday) 13:30 - 14:30 (Web seminar via eams)
