Salmon is one of the most demanding products a packaging film will ever meet. High fat content. Freezing temperatures. No margin for leakage.
We manufacture films built for exactly these conditions, under our own roof, for over 50 years. Niederwieser is a third-generation family business. Every film and every pouch we produce is extruded, printed, cut, and quality-checked in our own facility. No outsourcing. No intermediaries. One manufacturer, fully accountable for the material that runs on your line.
Fat migration into the sealing area disrupts bond formation. This is a material problem, not a machine calibration issue. Standard sealant layers were not designed for high-fat surfaces.
Below −18°C, standard films lose flexibility. At −38°C, punctures become routine during handling and transport. Film flexibility must be engineered in, it cannot be added retroactively.
Machine settings dialed in for one delivery become unreliable on the next. Downtime follows. This is what happens when films are sourced through intermediaries with no direct production control.
Demand for salmon packaging is seasonal and demand-driven. Inflexible lead times and large minimum order quantities put operations at risk during peak weeks and product changes.
Mono-material films are not a direct swap. Barrier properties, seal strength, thermoformability and mechanical resistance during shipment and display at retail, all need re-engineering before performance is maintained. Not every application is ready for it today.
Not in a lab under under constant and repeatable conditions. On real thermoforming and vacuum chamber machines, with real products, at real freezing temperatures.
Salmon packaging fails in predictable ways, on fatty sealing surfaces, at deep-freeze temperatures, under MAP gas pressure over time. Our films and pouches are specified and tested for exactly these conditions:
● High seal integrity on greasy surfaces
● Puncture resistance retained at −40°C
● High barrier properties to oxygen and gases used for MAP
● Recyclable mono-material options where technically feasible
● Flexographic printing up to 10 colors + 2 special finishes
Extrusion, printing, cutting, and quality control all happen at our facilities in Germany and Italy. There are no intermediaries between our production line and your machine.
● Dedicated team for your support
● Technical support for machine settings and trials
● Fast delivery
● Flexible minimum order quantities
● Sustainable material options available
The core of most inline thermoforming operations. Amilen is available in 3 variants, addressing a specific production requirement:
Amilen ML + MLX: Standard transparent flexible film with high clarity for retail presentation. Reliable seal integrity under normal thermoforming conditions.
Amilen CF: Engineered for fatty fish. A specialised sealant layer maintains seal integrity even when fat covers the sealing area. The right choice for salmon portions, fillets, and high-fat cuts where standard films produce inconsistent results.
Flexographic printing up to 10 colors, with 2 additional special finish options. Consistent print registration across runs. Used as printed top film in thermoform applications or as flow pack film. The print layer does not compromise barrier or seal performance.
Available in gusseted, embossed, printed, heat-resistant, and recyclable variants. Puncture-resistant at deep-freeze temperatures down to −40°C. Multiple size configurations available. Suitable for whole fillets, portions, and smoked salmon formats.
Mono-material and recyclable solutions are available across thermoforming film and vacuum pouch categories where performance requirements are met. This includes Amilen® PEx, Combilen® PEx for thermoforming applications and EasyVac® PEx vacuum pouches.
We do not list recyclable options as a default. We assess each application, sealing conditions, temperature range, barrier requirements, machine compatibility, and confirm whether a mono-material solution is technically viable. If it is not yet viable, we say so.
Seal failures, production downtime, and leaking product cost more than premium flexible packaging material. The economics are clear once you count the full cost.
Everything is made under our roof. Extrusion, printing, cutting, quality control. If something does not meet specification, we find it before it ships, not after it reaches your line.
Niederwieser is led by Sabine and Hannes Niederwieser — third generation. Decisions are made by people with their name on the building. That changes how problems get handled.
All materials are certified to relevant European food contact and packaging regulations. Documentation available on request. No shortcuts in the supply chain.
Our team has worked on thermoforming lines and vacuum chamber systems across Europe. When you have a question about material behavior, we answer with specifics not generalizations.
