How can I create a custom window for my pouch?

To create an individual window for your pouch, use a transparent film and choose the color "4/0-colored + white". The additional white ensures that printed surfaces appear colorful and opaque by being printed as opaque white under the printed design. This means that unprinted areas remain transparent and serve as a window. For a highly transparent window, we recommend a glossy surface material. A matt surface material makes the window appear milky. For more information on how to properly design with opaque white, see our print data guide for flexible packaging. Our media designers will be happy to answer any questions you may have at any time. Step by step instructions: Step 1: Download the appropriate print template for your pouch from our online shop. Then create the desired design in a suitable graphics program. We recommend for example Adobe Illustrator. Step 2: Create a new solid color called “HPI-White”. Then add all the elements that should be printed in white. You must then set all overlying elements of your design to “Overprint area”. Step 3: Save the finished print file as a PDF document and upload the document to the shopping cart under "Print data". You can find out more about creating the print data for your pouch in our print data instructions for flexible packaging .

What foods can I put in the pouches?

Yes, all our materials are certified for direct contact with food. Both our stand-up pouches and flat pouches are suitable for storing moist and dry foods in the form of pastes, powders or liquids. In addition, our materials each contain a functional barrier consisting of either EVOH, AlOx or aluminium. This barrier effectively protects the contents from aroma loss, oxygen penetration, moisture and potential UV radiation. Declarations of conformity or detailed material specifications are available from our customer support team .

What pouch materials are offered and what barrier do they provide?

We offer a wide range of materials for flexible packaging – from innovative mono-plastics and paper/plastic composites to plastic-free barrier papers. Each material is tailored to different requirements and offers specific protective functions for food, non-food and industrial products. Our materials are available in various designs, including white, transparent, metallised (e.g. by metallising PP) or with a natural paper look. In addition, different surfaces such as matt, glossy or soft-touch are available to customise the look and feel. All materials are equipped with a functional barrier – depending on the material composite, this is made of EVOH, AlOx or aluminium. These barriers provide reliable protection against aroma loss, oxygen, moisture and, if required, UV radiation. This makes them ideal for sensitive products. Depending on their structure, our materials are PPWR-compliant and certified recyclable. Our PE and PP mono films in particular enable a recyclable packaging solution without compromising on product protection or processability. To our material finder

How do I close / seal my bags?

After filling the bag, it can be securely sealed by welding it above the tear tabs with a hand sealing device. Depending on the material composite and thickness, temperatures between 140°C and 200°C are required for this. Larger quantities can be sealed with a semi-automatic sealing device. In the accompanying video, we show such a machine in action (20-30 bags/minute). This machine can be purchased through our customer support . You can find out more about filling and sealing flexible packaging in our magazine article "Filling and sealing Doypacks correctly" – a guide.

Many of our materials are available in two film thicknesses. The most suitable option depends on both the pouch size and the actual fill weight. As volume and weight are not directly linked, both factors should be considered when selecting the material. We will be happy to advise you on the right film thickness, and our sample boxes can also help you assess the material appearance, surface feel and stability in advance.

Barrier performance, application & appearance

The right materials for every application

Window panel

For window panels, we recommend transparent films from our range. With four-colour process printing (CMYK) plus white, transparent and opaque areas can be combined precisely.

Moisture barrier

For moisture-sensitive or hygroscopic products such as powders, cereals, dried fruit or spices, our PP and PE mono-materials with EVOH or metallisation provide reliable protection.

Oxygen barrier

For oxygen-sensitive products such as coffee, nuts, dried meat or oxidation-sensitive powders, our PP and PE mono-materials with EVOH or metallisation provide maximum aroma protection and extended shelf life.

UV/Lichtbarriere

For light-sensitive products such as supplements, vitamins or sensitive ingredients, we recommend our metallised PP mono-materials. They provide a particularly high level of protection against light and UV radiation.

Aroma barrier

For aromatic or odour-intensive products such as coffee, spices or cannabis flowers, our PP mono-materials with metallisation or an EVOH barrier provide reliable aroma protection – both inside and out.

Frozen applications

For frozen applications, we primarily recommend our PET/PE or mono-PE materials due to their favourable polymer properties. They are particularly suitable for products that need to be packaged reliably even at low temperatures.

Recyclability

For recyclable packaging solutions, we recommend our innovative PP and PE mono-materials. They are a modern alternative to conventional laminate structures, combining recyclability with reliable product protection.

Appearance & tactile feel

Our films are available in matt or gloss finishes – matt for modern, premium-looking packaging, and gloss for highly transparent window areas. For a distinctive tactile finish, we also offer Soft-Touch with a velvety surface and Paper-Touch with a paper-like look and feel.

Plastic or paper?

In many applications, plastic films provide the barrier properties and stability required. We primarily recommend paper-based materials for lightweight products where no barrier, or only a medium barrier, is needed.

Materials you can rely on

Design, tactile feel and perceived quality determine whether your product stands out on the shelf or goes unnoticed. Thanks to many years of experience across a wide range of product categories and close collaboration with leading brands and contract packers, we have developed a deep understanding of which pouch material best protects your product, runs reliably on your filling line and showcases your brand to best effect.

That is why we go one decisive step further: we develop and manufacture our laminate structures entirely in-house. This allows us to tailor barrier properties, film thicknesses and surface finishes precisely to your product, your application and your filling process – whether proven PET/PE laminates or forward-looking mono-materials made from PE and PP. The result: stand-up pouches in which every layer serves a purpose and is matched to your specific requirements.

FAQ

Frequently asked questions about our materials

Good to know

Materials for flexible packaging

AlOx - aluminium oxide

The abbreviation AlOx stands for aluminium oxide and describes an ultra-thin, high-barrier inorganic coating that is usually applied to PET and BOPP films using a vacuum process. AlOx barriers are applied to the carrier film with a thickness in the nanometre range and are transparent.

Aluminium

Aluminium (ALU) is used in packaging film as a thin functional layer when particularly high levels of protection are required. Aluminium barriers provide the ultimate protection against oxygen, water vapour and light. The most common application is as a middle layer in PET/ALU/PE composite materials; which protects the sensitive aluminium and at the same time enables the best processing properties.

Barrier films

A barrier film is a barrier layer integrated into the packaging that protects food, cosmetic products or industrial goods from external influences such as oxygen, water vapour, UV radiation or even mineral oils.

Film thickness

The film thickness, also known as film thickness, is measured in micrometres (µm) and, depending on the application, is a decisive factor for film stability, product protection and printing and finishing options. Films are used in various areas such as logistics, packaging production and construction. Depending on the application, films have special properties such as:

Monomaterial

In the context of flexible packaging, a monomaterial refers to a material that is primarily made from one type of plastic – typically PE or PP-based. As a common rule of thumb for design for recycling, a structure is considered ‘mono’ if at least 90% of its total weight consists of the target polymer. The remaining portion may consist of printing inks, adhesives or thin functional layers such as barrier films – provided these do not interfere with the recycling process.

EVOH

The abbreviation EVOH stands for ethylene vinyl alcohol copolymer. In flexible packaging, EVOH is used as a thin, organic barrier layer to protect products primarily from oxygen (and thus oxidation and aroma loss). In packaging films, EVOH is usually transparent and is therefore suitable for clear high-barrier packaging.

Metallisation

Metallisation refers to aluminium-metallised barriers that are applied to a carrier film (e.g. BOPP or PET) in nanometre-thin layers using vacuum coating (PVD). This process enables very high oxygen, water vapour and light barriers to be achieved with minimal material usage.

PET - polyester

Polyethylene terephthalate (PET) is a dimensionally stable, highly printable type of plastic that is primarily used as a printing and outer film in flexible packaging. Its excellent thermal stability in particular enables high mechanical loads and ensures dimensionally stable repeats over long print jobs.

PE - polyethylene

Like PP, polyethylene (PE) belongs to the polyolefin group and is one of the most popular packaging materials due to its properties. Polyethylene is considered tough, stable and easy to weld. It is therefore mainly used as an internal sealing medium for various flexible packaging such as bags, flow packs and sachets. In modern mono-material structures, PE in the form of MDO-PE is also used as a PET substitute for printing films. So-called coex films are often used for flexible packaging such as stand-up pouches – in this process, EVOH barriers, for example, are already incorporated (extruded) into the PE film during film production.
