Muri, 3 March 2026 – Industrial packaging has to do two things at once: protect products reliably and meet rising expectations around sustainability. At Fischer Söhne Extrusion AG, we address this challenge with a practical step toward circularity: our PCR (rHDPE) canister made from 100% in-house recycled material—regranulated from our own production scrap and returned to the process.

This solution is built for customers who want to reduce virgin plastic usage and move toward circular economy targets—without sacrificing performance in daily handling.

What “PCR” and “rHDPE” mean

PCR (Post-Consumer Recycled) describes recycled material that has been collected, sorted and recycled after consumer use, while rHDPE refers to the recycled polymer type (recycled high-density polyethylene). In practice, both terms are frequently used together in packaging discussions and specifications.

Why PCR (rHDPE) canisters?

Plastic packaging plays a vital role in protecting goods and reducing waste—but conventional plastic production is resource-intensive and contributes significantly to CO₂ emissions. Using Post-Consumer Recycled (PCR) HDPE (also called rHDPE) helps close the loop and reduce the environmental impact of industrial packaging.

Regulatory and market requirements are moving in the same direction. The EU is setting ambitious goals, including mandatory recycled content in plastic packaging (e.g., 30% by 2030) and stronger circular economy rules.

Why PCR canisters matter

Plastic packaging protects goods and helps prevent waste. At the same time, conventional virgin plastic production is resource-intensive and contributes significantly to CO₂ emissions. Using PCR HDPE (rHDPE) helps close the loop and reduce the environmental impact of industrial packaging.

In addition, the EU is tightening requirements around recycled content and circular economy principles—making recyclable concepts and recycled-content packaging increasingly relevant for many supply chains.

The sustainability impact: CO₂ savings

Beyond compliance, the climate impact is a major driver. In our material comparison, rHDPE can deliver up to 30–75% CO₂ reduction per kg of material, while remaining technically suitable for industrial use.

The same overview shows typical CO₂ values of ~2.0–2.5 kg CO₂/kg for virgin HDPE versus ~0.4–0.6 kg CO₂/kg for recycled HDPE (PCR), resulting in savings of ~1.6–2.1 kg CO₂/kg.

Our solution: the 100% in-house recycled canister

Our mono-layer recycling canister is produced from 100% regranulate recycled in-house. It is built on proven Swiss manufacturing quality and comes with a wide range of closures and accessories. Production is supported by certified and established management systems: ISO 9001 certified.

Key characteristics at a glance:

• Mono-layer recycling canister
• ISO 9001 certified
• Wide range of closures and accessories
• 100% in-house recycled regranulate
• Limited color selection
• Visibility stripes available upon request
• No UN approval (depending on application requirements)

CO₂ impact: a meaningful lever

Switching from virgin HDPE to recycled HDPE can deliver significant CO₂ savings. In our internal comparisons, recycled material shows substantially lower CO₂ emissions per kg than virgin HDPE, translating into savings on the material level.

Where PCR canisters create value

Our PCR (rHDPE) canister is a strong fit for customers who want to:

• reduce virgin plastic content in industrial packaging,
• demonstrate measurable progress toward circularity and ESG targets,
• keep packaging robust, stackable, and production-ready,
• work with a supplier that can support selection, testing, and implementation.

Challenges and what to consider

PCR solutions are not “one size fits all.” Regulatory requirements—especially UN approvals and food contact certification—can impact feasibility and product selection.

That’s why we discuss the right approach based on your use case, including material strategy, labeling/traceability expectations, and the required approvals for your market.

Looking ahead

Circular economy progress rarely happens with one single change. It happens when packaging, material, process capability, and customer requirements are aligned. That’s why we treat PCR solutions as a collaborative engineering topic—focused on feasibility, product performance, and compliance.

Let’s talk about your application

If you are evaluating PCR (rHDPE) packaging, want to reduce CO₂ footprint, or need guidance on feasibility under your regulatory requirements, our team in Muri will be happy to support..

Fischer Söhne Extrusion AG — Blow Molding. Packaging.

Lucerne, 22 January 2026 — From 20–22 January 2026, Fischer Söhne AG and Fischer Söhne Extrusion AG exhibited together at Swiss Plastics Expo in Lucerne. With ~200 exhibitors and around 3,800 visitors, the show once again proved to be the Swiss plastics community’s meeting point—from material suppliers and machine manufacturers to converters and solution providers.

What stood out on the show floor

Two topics ran through presentations and conversations alike: AI (from process monitoring to smart assistance) and sustainability (material efficiency, recyclates, circularity). The fair’s symposium featured 60 talks across two tracks, offering practical inputs on digital technologies and the circular economy—a strong framework for discussions at the stands.

Networking mattered just as much as technology. The Wine & Cheese gathering on day two created a relaxed setting for deeper exchanges; many visitors highlighted the value of quality time with suppliers and peers away from the busy aisles.

Highlights at our stand

Extrusion blow molding (EBM) in focus. Because EBM is comparatively rare in Switzerland, the split setup—Fischer Söhne AG (injection molding, life science) and Fischer Söhne Extrusion AG (extrusion blow molding)—sparked a lot of curiosity. Several schools requested plant visits to learn more about the process.

100% recycled canister (in-house recyclate). Fischer Söhne Extrusion AG presented a canister made entirely from in-house recycled material: production scrap is ground on site and returned to the process—a tangible step toward EU 2030 objectives and a practical proof of circularity.

Three-layer conductive canister. A technical eye-catcher, the 3-layer conductive canister illustrated how multilayer extrusion blow molding can combine protection, handling, and performance in one robust package.

A small detail with big reach. Our cotton tote bags were spotted all over the hall—an unplanned but welcome sign of how far conversations from our stand traveled.

Community and knowledge transfer

Beyond equipment and materials, the KUNSTSTOFF.swiss “Zmorge” offered a friendly breakfast with excellent coffee, “Gipfeli,” and time to compare notes with fellow members—exactly the kind of exchange that keeps the Swiss plastics ecosystem vibrant.

Apprentices on tour

Because the show was close to home, our commercial apprentices joined the team to explain products and services, practice customer conversations, and explore the latest developments. Our plastics technician apprentices also toured the exhibits to see where the market is headed. True to form, they used the opportunity to create short TikTok clips—sharing a learner’s view of the industry with their peers. For us, this is training in action: real context, real questions, and real engagement.

Our takeaway

Swiss Plastics Expo 2026 was less about big deals on the day and more about meaningful connections: targeted discussions, new contacts, and invitations to continue technical exchanges—particularly around recyclate use, conductive canister, and line-ready life-science packaging. For Fischer Söhne, it was also the right moment to show the market our two-company setup:

• Fischer Söhne AG for injection molding, life-science components, and Tub & Nest;
• Fischer Söhne Extrusion AG for extrusion-blown molding packaging, including standard and custom canisters with decoration and testing.

Together, this gives customers focused expertise with seamless collaboration—from concept and toolmaking to validated production, assembly, and logistics.

Continue the conversation

If we didn’t catch each other in Lucerne—or if you’d like a deeper dive into recyclate strategies, conductive canister – mono- and 3-layer technology, or Tub & Nest / CMO capabilities—our teams in Muri are happy to set up a follow-up (virtual or on site).
