What is the smallest size available for Flat Pouches?

Our online calculator offers a wide range of options for flat pouches, but not all combinations can be covered online. The minimum size varies depending on whether a zipper is to be integrated into the pouch or not. Contact our customer service for a quote outside of our online options. Minimum size stand-up pouch: Flat pouch without zipper: 57 mm x 70 mm (width x height) Flat pouch with zip: 70 mm x 100 mm (width x height)

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 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 is the actual fill level for my bag?

Depending on which additional components (zippers, tear tabs, and hangers) you choose, the actual fill height of your bag will differ from the height in the calculator. Please consider the following dimensions when configuring your bag packaging: Distance top edge to zipper: 40 mm Distance top edge to tear flap: 21 mm Distance top edge to Euro hole / hole suspension: 16 mm

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 .

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.

How do I get a pouch pattern?

We offer comprehensive sample boxes for all our products, containing a wide selection of materials and sizes. This allows you to get a first impression of our range of materials, the different bag volumes and our printing and finishing quality. If you would like an individual sample print of your design, this is also possible. Simply contact our customer support for further information.

Where can I get a declaration of conformity and other documents?

We provide the following documents for all our materials and other components of the bags: Technical data sheet NIAS declarations REACH declaration PFAS statement declaration of conformity We will be happy to send you the relevant documents upon request.

INTERESTING FACTS

Guide to seal edge bags

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.

Sealed edge bags: versatile packaging solutions

Sealed-edge bags are extremely versatile packaging solutions that are widely used in various industries thanks to their high puncture resistance and good oxygen and moisture barrier properties. Their applications range from the food industry to pharmaceuticals and cosmetics. These bags are characterised by their double-sided sealed edge, which ensures a secure and permanent seal of the selected material without the need for an additional closure mechanism.

Sealed edge bags: structure and properties

The structure of a seal-edge bag usually consists of several layers of high-quality materials such as PE, PET, aluminium or natural paper, which provide an optimal barrier against moisture, oxygen and other external influences. These multi-layer material composites not only ensure a high level of product protection, but also a long shelf life of up to 24 months for the packaged products. This is supported by various barrier layers made of aluminium, EVOH or AlOx, for example.

In addition, the seal edge bag is designed to offer various additional options, including a tear tab, a press seal / press seal, a Euro hole for easy retail presentation and multi-colour printing for attractive product presentation. The alternative option of labelling on the seal edge bags allows for easy identification and brand boosting for manufacturers and retailers. Printed labels can also be found in our shop.

The manufacturing process involves folding a long strip of material in the middle, followed by creasing. The left and right sides are then welded together by machine, while the top remains open to allow filling.

Possible applications for seal edge bags

Sealed-edge bags have a wide range of applications. They are ideal for packaging foodstuffs such as coffee, snacks, dried fruit and frozen products, as they enable safe and hygienic storage. They are also used in the pharmaceutical industry for packaging tablets, capsules and powders, as they provide a reliable barrier against moisture and light. In the cosmetics industry, they are used for packaging creams, lotions and other liquid or semi-liquid products. They are also often used for single-use portions, which further expands their range of applications.

Sealed edge bags in cannabis and CBD packaging

The growing legalisation and acceptance of cannabis and CBD products have led to an increasing demand for high-quality packaging solutions. Seal edge bags perfectly meet these requirements by not only ensuring safe storage, but also preserving the freshness and quality of the products. Thanks to their versatility, seal edge bags can be manufactured in various sizes and shapes to meet the different requirements of cannabis and CBD packaging. They are user-friendly and offer practical features such as resealable zippers and tear-off tabs. The aesthetic design of so-called Flat Pouches, with multi-colour printing and labelling options, helps to strengthen the brand image and present the products in an appealing way. This is crucial in a competitive market where packaging has a significant influence on consumers' purchasing decisions.
