Questions You Should Know about stand up pouches manufacturer

Stand-up pouches can be produced in many different ways. There are different production techniques, especially regarding the bottom fold. A difference is made above all between a normal Doyen bottom and a so-called K-seal bottom.

The two variants differ in the way the bottom fold of the pouch is integrated between the front and the back. The Doyen bottom has the disadvantage that a format-specific tool has to be ordered for it in each case. The K-seal bottom, on the other hand, has the advantage that any format can be produced with one and the same tool.

HaiPak supply professional and honest service.

We use both manufacturing variants in our production. We always produce our Doypacks in fixed formats with a Doyen bottom. Orders with a pouch in the desired format, we always produce with the K-seal bottom.

Plastic or paper stand-up pouches

A stand-up pouch can be made from a wide variety of materials. The most common material combinations are:
 

• Composite plastics such as PET/PE
• Kraft papers such as KRAFT/PET/PP

Depending on the material, different properties result in terms of feel, print image, food compatibility and recycling. Especially pouches made of kraft paper are very popular, provide a very high-quality feel and always convey a sustainable image. In most cases, however, the material combinations of paper and plastic used are not officially recyclable (in Germany).

In order to be able to recycle a stand-up pouch, the material used must be made of a so-called mono-material (e.g. PE/EVOH/PE). It is important that both the foil and components such as the zipper are made of one and the same material (PE foil + PE zipper). The most common mono materials are made of mono-PE and mono-PP.

Plastic-free or industrially compostable stand-up pouches are also available, but these do not meet the same high requirements for the necessary barrier functions as, for example, an EVOH barrier does. The inner coatings of these pouches often consist of ultra-thin varnishes or organic coatings. These pouches usually also have significantly lower stability and durability.

Stand up pouch with viewing window

Pouches with a viewing window are particularly suitable for optimum presentation of goods at the point of sale. The viewing window is highly transparent, can be specified in variable size and all barrier properties of the material are of course still fully retained.rlich weiterhin voll erhalten. 

For an individual viewing window, it is necessary to select a transparent foil. This foil is the requirement for transparent / see-through areas. A viewing window is automatically created in all areas that are not printed. However, so that the printed areas of the pouch do not also appear slightly transparent, an additional opaque ink is often printed under the printed image. We use a so-called opaque white for this, which ensures that the background of the printed areas is no longer transparent. For this option, you can select in our calculator the color "4-color Euroscale + white".

You can find out how these requirements must be technically implemented in the print data in our print data instructions for stand-up pouches.

Unique metallic effects

In order to be able to implement more eye-catching packaging designs, we also offer our standard pouch foil in a silver metallic version. The surface of the foil is double-sided metallic and allows special metallic effects. The resulting effect is comparable to hot foil stamping. The advantage, however, is that any desired color can be metallized. The structure of the print data is very similar to the structure of the stand-up pouches with viewing window.

All printed areas that are not backed with opaque white (HPI-White) automatically appear metallic. All elements with opaque white background (images, texts, shapes, etc.) have no metallic effect.

Because most stand-up pouches are intended for direct contact with food or pet food, the pouch materials must meet many different requirements. The main concern is the protection and durability of the contents. The contents must be protected from the following influences:
 

• UV radiation
• Humidity / water vapor
• Oxygen

Depending on the contents, the flexible packaging market uses either materials with no barrier, materials with a low barrier, or materials with a very high barrier. The barrier layers used for this purpose are divided into organic and inorganic barriers. Each barrier must be of sufficient thickness to ensure adequate protection for the contents.

• Inorganic barriers: e.g. aluminum foils, silicon oxide (SiOx), etc.
• Organic barriers: e.g. polyamide (PA), ethylene vinyl alcohol (EVOH), etc.

The industry standard barrier film thicknesses are between 2-8 µm. The EVOH barrier is one of the most effective barriers against oxygen, aromas and water vapor.

We offer a wide range of stand-up pouch sizes, including 250ml, 500ml, ml, and various width options such as 80mm, 100mm, and 120mm. We can provide the most suitable size based on your specific requirements.

We offer customized manufacturing services for stand-up pouches, including custom design and sample development. Typically, the lead time for custom orders is 10-15 working days. We will assign a dedicated person to follow up and ensure on-time delivery.

Our stand-up pouches are primarily made of PE, PET, and VMPET materials. PE is lightweight and durable, PET has high transparency and excellent moisture barrier properties, while VMPET composite film offers superior oxygen and light barrier performance. You can choose the material that best suits your product characteristics and budget.

We provide printing services for our stand-up pouches, including single-color, multi-color, and hot-stamping options. The printing quality is precise and realistic, allowing you to effectively showcase your brand image. The printing costs will be determined based on the specific techniques and order quantities, and we can provide you with a professional pricing proposal.
