Business Details

A segment that manufactures and sells flexible packaging materials made primarily from paper, plastic film, metal foil, and other materials. Its main products are packaging for food (microwave-compatible "Range Do!" etc.), packaging for pharmaceuticals and medical use (high moisture-barrier PTP packaging film "Techni Film" etc.), and packaging for daily necessities, with nearly all sales directed to domestic users. Leveraging the Group's core technologies—lamination technology, coating technology, and multilayer film extrusion technology—the segment provides composite packaging materials for a wide variety of applications. Affiliated companies participating in this business include Toho Resin Industry Co., Ltd., Nesco Co., Ltd., and Zan Ying (Shanghai) Trading Co., Ltd.

Recent Overview

Sales declined 1.9% year on year, but segment profit rose 82% year on year due to profitability-focused restructuring of order composition

Sales for FY2026 (ending March 2026) were ¥12,322 million (down 1.9% year on year). For food packaging materials, orders for "Range Do!" decreased due to consumer purchase restraint following price increases by food manufacturers, and orders for daily necessities packaging materials also decreased due to order adjustments for low-margin products and changes in packaging form. On the other hand, orders for pharmaceutical and medical packaging materials, including "Techni Film," remained steady. Order adjustments for low-margin products and appropriate pricing of products were successful, resulting in a significant improvement in segment profit to ¥290 million (up 82% year on year).

Key Products

product
Range Do!

A microwave-compatible food packaging material developed mainly for the retort food category. In FY2026 (ending March 2026), orders decreased due to consumer purchase restraint following price increases by food manufacturers. Going forward, the company plans to expand its lineup and promote sales expansion centered on the retort food category while also considering expansion into adjacent fields.

product
Techni Film

A high moisture-barrier film used for PTP (Press Through Package) packaging for pharmaceuticals. In FY2026 (ending March 2026), orders for pharmaceutical and medical packaging materials overall remained steady, supporting segment profitability.

product
Purapika

A content-resistant packaging material used for daily necessities and other applications. In FY2026 (ending March 2026), orders decreased due to order adjustments for low-margin products and changes in packaging form.

product
Mono-material & Paper-based Packaging

A group of packaging materials developed and commercialized in response to environmental issues arising from plastic containers and packaging. This includes pouches that serve as substitutes for plastic bottles, packaging materials made primarily from paper or biodegradable plastics, and mono-material products that facilitate easy recycling.

Growth Drivers

  • Increasing demand for pharmaceutical and medical packaging materials (structural demand driven by an aging population and increasing numbers of patients with chronic diseases)
  • Lineup expansion of the microwave-compatible food packaging material "Range Do!" and sales expansion into the retort food category and adjacent fields
  • Improved profitability through a profitability-focused revision of product mix and appropriate pricing of products (shift toward higher value-added products)
  • Acquisition of new demand through development and sales expansion of sustainable packaging materials, including mono-material, paper-based, and biodegradable plastic packaging
  • Development and sales expansion of new products leveraging technological capabilities in cosmetics, daily necessities, and medical and pharmaceutical packaging

Risks

  • Decrease in orders for food packaging materials (particularly "Range Do!") due to strengthened consumer cost-saving sentiment amid rising food prices
  • Market contraction due to the declining birthrate and population decrease in the domestic market, and intensifying competition with rival manufacturers
  • Increased costs due to rising prices of raw materials (paper, plastic film, metal foil, etc.)
  • Increased costs to comply with stricter plastic regulations and decarbonization requirements
  • Short-term sales decrease due to order adjustments for low-margin products and changes in packaging form for daily necessities packaging materials
