How are stand up pouches made?

In short, stand up bag is a pouch that can stand by itself without other support. Until the 1980s and 1990s, with the development of materials, design, and equipment, the application of bags increased. Today, standing bags have become the first choice for many well-known brands. The company uses these sealed bags for weed, coffee, tea, pet food, beauty product packaging, etc.

Basic Material Structures

The standing bag is made of multiple layers of barrier materials laminated together. The performance of packaging is related to the quality of barrier material and the structure of the bag. Therefore, choosing a higher-quality bag ultimately means fewer problems. There are usually 2-3 layers in the construction of a stand-up pouch, including the outer layer, middle layer, and inner layer. Each layer has different structures and provides a protective barrier to protect the contents from factors including oxidation, moisture, light, odor, or a combination of these.

Outer Layer

  • OPP (Oriented polypropylene)
  • Kraft paper
  • PET (Poly (ethylene terephthalate))
  • PE (Polyethylene)

Middle Layer

  • Kraft paper
  • PET(Poly (ethylene terephthalate))
  • VMPET (metalized PET film)
  • AL (Aluminum Foil)

Inner Layer

  • CPP (Cast polypropylene)
  • PE (Polyethylene)
  • PET(Poly (ethylene terephthalate))

For kraft paper film structure, PackagingBest offers several exterior options, including natural kraft paper, white kraft paper, black kraft paper. Excellent appearance is good for developing your brand and can attract customers to buy your product. Natural kraft paper is environmentally friendly and all-natural. White and black kraft paper stand-up pouches give a sense of atmosphere and effectively combine with the natural feel of kraft paper. Kraft paper is not only chosen for its good appearance but also for its durable quality. In addition, a kraft paper stand-up bag is a good choice for customers who need labeling and hand stamping. Please promise me that when you want to build your brand, you must avoid inferior packaging, even if it is cheaper. Quality packaging will bring you quality customers.
