Which materials are recyclable and are there recycling certificates?

Some of our materials are fully recyclable and can be disposed of either via the yellow bag (for plastic) or the blue/green garbage can (for waste paper). The recyclability of our materials is confirmed by the Cyclos-HTP institute. Conformity with the following standards is also certified: Minimum standard for assessing the recyclability of the ZSVR (German Central Agency Packaging Register). DIN EN 13430 with regard to recyclability in the post-consumer phase. Below you will find a list of our materials that are certified as recyclable: Material designation Film thickness Disposal Recycling code Recycling certificate White PP mono film 116 & 46 µm Plastic (yellow bag) 5 PP in certification PP mono film, pearl white 123 µm Plastic (yellow bag) 5 PP in certification Transparent PP mono film 108 & 138 µm Plastic (yellow bag) 5 PP in certification PP mono film, metallic silver 106 & 136 µm Plastic (yellow bag) 5 PP in certification White PE mono film 95 & 125 µm Plastic (yellow bag) FULL-PE Yes Transparent PE mono film 95 & 125 µm Plastic (yellow bag) FULL-PE Yes White paper, without plastic 65 & 75 µm Waste paper (blue bin) 22 PAP Certified by manufacturer

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.
