Inverted pouches upend food packaging: Sempack

By Rick Lingle in Pouches on April 23, 2019

Now 100% recyclable as #2 HDPE, the distinctive conical Sempack pouch can be uniquely positioned as a stand-up or inverted pouch.


As the fourth in a series on the fast-growing inverted pouches market within the relatively more mature category of stand-up pouches, Packaging Digest presents an interesting twist: the unique Sempack from Semco.

Sempack brings a new shape to this inverted take on stand-up pouches, conical. If you combined a tube, pouch and bottle, the result that uniquely has benefits of all three would look something like the pouch supplied by Monaco-based Semco.

Another novel aspect is that the standard Sempack can be marketed and shelved as a stand-up pouch or reoriented 180 degrees as an inverted pouch. We drill down into the one-of-a-kind packaging in a Q&A with exclusive input from Wenael Regnier, CEO, Semco S.A.M., and Rob Clare, applications development specialist, Nova Chemicals, which undertook the development of the new recyclable version.


Compare this pouch with the inverted pouch packaging as seen in the Chobani article.

Regnier: Based on the pastry bag concept, the Sempack packaging format is a flexible conical pouch composed of a 100%-recyclable, multilayer film. With its truly unique design, the Sempack pouch is versatile, offering the ability to stand up or down. The Sempack is the perfect mix between a bottle, tube, and standard pouches, and it is fun—a significant factor in the customer experience of any package.

Clare: Functionally, the Sempack pouch will operate the same as other squeezable pouches, but it offers more variety in accessory options and the ways in which it can be filled and sealed. It's suitable for food and nonfood applications.

With its original and ergonomic design, the Sempack pouch is suitable for a variety of products, ranging from liquids to pasty or semi-pasty substances to powders, and for many industries, including food and beverage, cosmetic, pharmaceutical and industrial.

What’s the history of the original Sempack?

Regnier: The Sempack flexible packaging format was invented and patented in 2012 by SEMCO S.A.M.—a leading expert in the packaging field, established in Monaco in 1971. The product was first introduced in 2015 and is patented in 47 countries.


Is it a premade pouch? How is it filled?

Clare: The Sempack pouch is currently a premade packaging product that can be filled by conventional filling and lidding equipment.

Semco is currently working on the second generation of the Sempack manufacturing process, with a form-fill-seal line as the next step.


What kind of reception has the packaging received?

Regnier: There has been significant interest in the Sempack pouch since it was first introduced—initially within the food market and then with various cosmetic brands.

Semco also received several inNovation-based awards at international tradeshows, such as:

  • Packaging of Perfume Cosmetics & Design (PCD) 2015 in Paris;
  • SIAL in Paris; and
  • Packaging InNovations in Birmingham, United Kingdom

Semco also has completed extensive consumer research, confirming market demand.


What sizes, closures and other options are possible?

Regnier: The Sempack pouch is fully customizable and offers:

  • Different sizes: 200ml; 300ml; and 600mL;
  • A wide range of possible film structure designs;
  • Multiple printings and customization;
  • Various collar sizes/adaptations;
  • Numerous accessory choices are available, including standard caps, flip-top caps, disc tops, caps with valves, and more.


What are the printing options?

Clare: Sempack pouches can be decorated by conventional direct printing methods, such as flexographic or digital, and can be surface- or reverse-printed.


What was the specific original structure?

Regnier: The original Sempack pouch structure was a non-recyclable, mixed-material triplex laminate that was designed to give stiffness, barrier, and sealability to the fitment, base, and lap seal on the pouch body section.
