Solutions for the alternative proteins industry

More and more people are either consistently vegetarian or vegan, or have become flexitarian, meaning that they occasionally and consciously decide not to eat animal products. Experts see this change not as a short-term hype, but as a real megatrend that will prevail. This is also due to modern plant-based alternatives, which come very close to their animal-based role models in both taste and consistency. Looking for a suitable packaging system for your alternative proteins? SEALPAC has the answers.

FAQ sobre Proteínas alternativas

  • Can the machine achieve the required shelf life for plant-based products or alternative proteins whilst preserving their texture, color, and freshness?

    Owing to their consistent sealing process, regardless whether using modified atmosphere packaging or vacuum skin packaging, SEALPAC traysealers and thermoformers always guarantee maximum shelf life. Naturally, this also depends on the packaging materials used and the production environment (e.g. hygiene and temperature). In today’s world, the main challenge is reducing plastics whilst maintaining the shelf life of alternative proteins or plant-based products. For each product, we support our customers by reducing the thickness of plastic used in their current packaging, as well as by introducing hybrid solutions, where most of the plastic is replaced by cardboard. In case of hybrid solutions, we enable the consumer to separate the individual materials after use. By throwing these materials away in the appropriate waste bins, recycling is made easy. In case of 100% plastic packaging, we have optimized our traysealers to handle so-called ultra-light trays. Since 2014 already, we offer our EasyLid® system for reclosable packaging, due to which the common snap-on lid can be eliminated. This leads to weight reductions of up to 40%. On our SEALPAC thermoformers, we offer the unique SmartShape forming system that achieves an improved consistency, particularly in the corners of the pack, without requiring an additional stamp mechanism. As a result, up to 10% thinner films can be used. All this, without compromising on shelf life.

  • Can the machine reliably run recyclable, mono-material, or fiber-based packaging?

    Each machine supports a wide range of packaging solutions, from classic MAP applications to today’s sustainable material concepts. Innovative packaging features can also be integrated, such as the unique EasyPeelPoint system, which enables particularly user-friendly opening of the pack by the consumer. The combination of high precision and intelligent control ensures that the machine reliably handles even the most demanding materials and geometries. Both our traysealers and thermoformers are capable of handling any modern, recyclable, ultra-light, or mono-materials without headaches.

  • What packaging formats are supported (MAP, vacuum skin, resealable, convenience formats, etc.)?

    Since the foundation of our company, SEALPAC machines have been designed to run all of today’s and tomorrow’s packaging concepts on the same base machine. This includes classic modified atmosphere packaging, vacuum skin packaging, and shrink packaging, but also more complicated packaging concepts such as separate InsideCut. As packaging experts, we would gladly sit down with you to design the optimal pack for your alternative protein or plant-based product.

  • How flexible is the machine for frequent SKU and format changes?

    All SEALPAC machines are equipped with innovative quick tooling exchange systems that make switching between different applications easy and avoid unnecessary machine downtime. On our thermoformers, for example, the sealing top tool can be replaced with minimum effort using a special trolley. This makes the exchange not only much quicker, but also safer for your employees, who no longer have to lift or carry heavy components. Other quick exchange systems include the side exchange or swivel table for bottom tools. On our traysealers, we offer the possibility for a tooling exchange from both sides of the machine using a unique SEALPAC trolley with integrated power connections. As such, a format change can take place within minutes.

  • What output can realistically be achieved for our production volumes?

    The output always depends on a number of factors, such as product, format, packaging concept, and production environment. A packaging line can only go as fast as its slowest component, but this will not be the SEALPAC packaging machine. As an example, our A10max traysealer in double-lane execution could package 200 trays per minute under MAP (based on a 190 x 144 mm tray). However, line efficiency is also important. Every unplanned interruption, inefficient movement, or disruption in the process directly impacts production costs. Against this backdrop, our packaging machines are consistently designed for stable, reproducible processes. We rely on robust construction, intelligent monitoring systems, and automated assistance functions that ensure flawless operation, again and again. As such, we achieve the highest OEE in the market, sometimes up to 99.5%.

  • How easy is the machine to clean and prevent allergen cross-contamination?

    Due to their sophisticated design with optimal accessibility, SEALPAC traysealers and thermoformers stand for enhanced protection of both product and personnel. Whether it concerns the stainless-steel body that can be hosed down, the integrated slopes that optimize water drainage, or the avoidance of interfering contours: our machines allow for fast, simple and reliable cleaning.

  • How attractive and premium is the final package presentation on retail shelves?

    With a perfect recognition of market-defining trends, SEALPAC quickly converts these into innovative products, systems, solutions and services. We work closely together with leading manufacturers of packaging materials to develop consumer-driven total solutions, which will improve your production’s efficiency and profitability. We work jointly with you towards the optimal solution for your individual application, so that every single one of your products will impress your customers, and that your long-term success at retail is secured.

  • What are the operating costs for film, gas, energy, and maintenance?

    When evaluating a packaging line, simply looking at the investment costs is no longer sufficient. What matters is how efficient the line is in daily operation and what the actual cost per package is. Energy consumption, material usage, changeover times, uptime, and process stability, even when using more challenging mono-materials, are directly interconnected. The total cost of ownership can only be determined by knowing your exact production details. In general, we know that the investment costs of a SEALPAC machine are less than 3% of the total line costs, that we have 90% less air consumption by using servo technology, that we can run up to 10% thinner films on our thermoformers due to the SmartShape forming technology, that we can place 33% more trays in a tool by running Long Side Leading, and that we have up to 30% less film consumption with InsideCut whilst achieving an excellent product appearance. Furthermore, our machines are built to last: over 95% of every traysealer or thermoformer ever built is still in operation!
