Joint Development of Low-Contamination Release Liners (Zero Adhesive Residue) | Balancing Functionality and Quality through Optimized Blending of Adhesives and Curing Agents

Release liners that suffer from poor compatibility with adhesives, leading to adhesive residue after peeling—we break through this physical property limit by optimizing the blend of adhesives and curing agents, combined with partnership with our partner manufacturers. Through a joint development scheme built on repeated prototyping and evaluation, we have simultaneously achieved enhanced functionality/performance and consistent quality. The Barrier of "Low-Contamination Requirements" Standing in the Way of New Product Tape Development Seeking to develop a release liner with zero adhesive residue for a new tape product, as existing products fail to meet low-contamination requirements.Poor compatibility with the adhesive results in trace amounts of residue remaining after peeling.●Situations where the issue manifests: New product development phase.●Primary impacts: Adhesion failures, peeling failures, and competitive pressure to switch to alternative suppliers' products. Why Zero Adhesive Residue Cannot Be Achieved: Poor Interfacial Compatibility Between the Adhesive and the Release Layer Physical property limits of existing liner materials. Poor compatibility at the interface between the adhesive and the release layer.●Basis for Identification: Product research and prototype evaluations. Countermeasures Attempted So Far and Their Limitations Changing the types of existing liners (only limited improvement), or adjusting the peeling force alone (contamination issue remained unresolved).Based on these limitations, we adopted the following approach as a more fundamental and drastic countermeasure. Solution Approach: Optimizing Adhesives & Curing Agents Blending × Joint Development Scheme Jointly optimizing the blending of adhesives and curing agents with the customer by proposing new materials + changing existing grades. STEP. 01 Material Proposal Proposing multiple release layer and adhesive candidates for low-contamination applications STEP. 02 Blending Optimization Reducing post-peeling contamination by modifying the curing agent ratio STEP. 03 Iterative Prototyping & Evaluation Conducting repeated evaluations on-site in collaboration with partner manufacturers Fujichemi Trading's Service Delivery Network: Head Office × Partner Manufacturers × Customers (Adhesive Evaluation) This solution is established through a clear division of roles across multiple locations.・Head Office / Domestic Sales: Project window (point of contact)・Partner Manufacturers: Supply of release layers, adhesives, and curing agents, along with technical expertise・Customer (Tape Manufacturer): Evaluation on the adhesive side●Supply System: Joint development scheme, supporting small-lot supply during the development phase. Results achieved through implementation Achieved enhanced functionality/performance, consistent quality, and a reduced defect rate.●KPI Candidates: Improvement in contamination test pass rates / Improvement in customer-side yield.●Implementation Lead Time: Mid-to-long term development project with repeated prototyping and evaluation. Anticipated Ripple Effects and Horizontal Expansion The implementation effects of this solution go beyond solving the primary issue. Please also leverage this as material for internal and executive-level proposals.・Commercializing the "combination proposal" of release layer × adhesive layer × curing agent・Establishing a strong presence as a bridge between adhesive manufacturers and film manufacturers Differences from Competitors: Why Fujichemi Trading is Chosen Adhesive manufacturers alone often find it difficult to commit deeply to the release layer side. As a trading company capable of cross-functionally handling "release layers × adhesives × curing agents," Fujichemi can fulfill the role of a collaborative hub.

High-Quality Die-Cutting of LIB / Solid-State Battery Electrodes | Eliminating Burrs and Cracks with Nogami Giken Hand Punches

Die-cutting defects (burrs and cracks) occurring in the electrode evaluation of LIBs and solid-state batteries directly impact the reliability of evaluation data and development schedules. We propose high-performance hand punches manufactured by Nogami Giken, combined with test equipment lending and paid testing. This simultaneously improves evaluation accuracy and development speed while lowering implementation risks. Burrs and Cracks Frequently Occurring in LIB / Solid-State Battery Electrode Evaluation Burrs and cracks occur during electrode die-cutting (test samples) for LIBs and solid-state batteries, compromising the reliability of evaluation data. This affects development schedules.Existing hand punches have insufficient compatibility with electrode materials (thin films and brittle materials).● Scenarios where this becomes apparent: Existing product improvement and new material evaluation phases.● Main impacts: Increased variance in evaluation data, development delays due to re-evaluation, and risks in mass production investment decisions. Why Burrs and Cracks Cannot Be Resolved: Limitations of Blade Shape, Load Settings, and Material Compatibility In addition to the physical property limits of existing materials, there are constraints in the processing design (existing punch blade shapes and load settings).● Grounds for identification: Interviews with responsible personnel and comparative tests with existing hand punches. Countermeasures Attempted So Far and Their Limits Blade replacement of existing punches (limited burr reduction) and trial use of laser cutting (thermal effects occurred).Based on these limitations, we adopted the following approach as a more fundamental solution. Solution Approach: Proposing Nogami Giken Hand Punches × Test Equipment Lending × Paid Testing Developing new opportunities with overseas manufacturers: Assisting implementation decisions through the proposal of hand punches manufactured by Nogami Giken, test equipment lending, and paid testing.

Local Procurement of Motorcycle Key Management Sheets in Vietnam | Balancing Quality, Cost, and Lead Time with PS Sheets + Die-Cutting

In conjunction with the startup of mass production in Vietnam, the customer wanted to transition from importing PS sheets from Japan to stable local procurement. We sourced and newly developed alternative global materials that met the required physical properties, and implemented a seamless, end-to-end process up to die-cutting into barcode label shapes at our Vietnam base. This successfully achieved both cost reduction and shorter lead times compared to importing. The "Limitations of Importing Japanese Goods" That Surfaced with the Mass Production Startup in Vietnam The customer wanted to stably procure PS sheets used as a barcode printing base material locally. When importing from Japan, tariffs, logistics costs, and lead times became major bottlenecks.While the local materials needed to satisfy the quality requirements, the framework to integrate them into local logistics was not yet established.●Context of Occurrence: Overseas expansion and local procurement phases. Vietnam production base startup / stabilization of mass production.●Main Impacts: Inflation of import costs, failure to meet localization targets, and falling behind local competitors in price competition. Why Localization Stalls: Local Suppliers' Quality Variance and Dependency on Japan Quality variance among local suppliers / Prolonged procurement lead times due to dependency on Japanese products.●Specific Basis: Conducted quality and cost hearings via our Vietnam base, and performed physical property comparisons of local candidate products. Countermeasures Attempted So Far and Their Limitations Diverting local off-the-shelf products (Rejected due to poor print durability); Continuing to import Japanese products (Failed to meet cost targets).Based on these limitations, the following approach was adopted as a more radical and decisive solution. Solution Approach: Sourcing Global Suppliers × Local Die-Cutting in Vietnam × Local Inventory Simultaneously and drastically improving quality, cost, and lead times through the sourcing of global manufacturers' products combined with a turnkey supply that includes local die-cutting. STEP. 01 New Supplier Sourcing Scouted alternative global materials that match the required physical properties through the Fujichemi Network STEP. 02 Local Processing Die-cutting into barcode label shapes at our Vietnam base STEP. 03 Inventory Management & Supply Storing required quantities locally to ensure Just-In-Time delivery Fujichemi Trading's Supply Framework: Vietnam Base × Partner Manufacturers This solution is made possible through a clear division of roles across multiple bases.・Vietnam Base: Supplier selection, die-cutting, inventory, and shipping・Partner Manufacturers: Stable supply of master roll PS sheets●Supply Framework: Local master roll inventory + die-cutting → Direct delivery to the assembly line. Outcomes and Results Delivered Achieved localized production, resulting in cost reductions as well as improved lead times and supply stability.●Potential KPIs: Cost reduction compared to importing / Shorter lead times / Reduction in inventory days.●Implementation Lead Time: Phased transition from supplier selection through to the startup of local processing. Expected Ripple Effects and Horizontal Roll-Out The benefits of implementing this solution extend far beyond solving the primary issue. It can also be utilized as strategic material for internal and executive proposals.・Expansion into key management for applications beyond motorcycles (automobiles, construction machinery, agricultural machinery)・Development of proposals for printing sheets other than PS (PET, PVC, coated paper)・Replicating the same scheme from Vietnam to Thailand and Indonesia・Messaging "Japanese Quality × Local Pricing" as a core axis of differentiation against local competitors Differentiation from Competitors: Why Fujichemi Trading is Selected Local trading companies often have limited processing capabilities and variance in quality. In contrast, Fujichemi provides an integrated solution combining Japanese-style quality control and die-cutting processing at our Vietnam base.

We can also handle printing sheets such as PET, PVC, and coated paper. Please consult with us regarding your required physical properties. What is the extent of the price difference compared to local products? While our unit price can be higher than local products, there are many cases where we offer a distinct advantage in total cost when factoring in print durability and quality variance. Can this be rolled out to countries other than Vietnam? We can support the roll-out under the same scheme to other ASEAN countries such as Thailand and Indonesia. Can you handle secondary processing other than die-cutting? We also accept consultations for secondary processing, including printing, laminating, and roll slitting and rewinding. What is the minimum order quantity? We can accommodate small-lot requests from our local inventory. Specific lot conditions are subject to consultation.
