Stand Up Pouches: Análise completa desde o material até à aplicação

stand up pouches-guide

As a typical representative of modern packaging, stand up pouches occupy a critical position in the flexible packaging industry with their unique inclusiveness and functionality. As people’s expectations for packaging continue to increase, stand-up pouches have become the only choice for major manufacturers due to their convenience, unique appearance, and energy-saving and environmentally friendly characteristics.

Stand up pouches first appeared in the early 20th century. At that time, the technology was relatively simple and the application of materials was relatively simple, to meet the packaging and transportation needs of products. However, with the improvement of people’s requirements for packaging and the development of plastic science, composite materials came into being and were applied in the production of stand up pouches. The multi-layer composite structure improves the barrier properties of stand up pouches. As people’s environmental awareness gradually increases, more and more packaging bags use recyclable or biodegradable materials, which promotes the sustainable development of the packaging industry. An environmental protection journey has begun.

The Material Structure of Stand Up Pouches

  • Single-layer plastic: including low-density polyethylene (LDPE), high-density polyethylene (HDPE), polyethylene terephthalate (PET), and biaxially oriented polypropylene (BOPP). These materials are widely used due to their good barrier properties and good processing properties.
  • Folha de alumínio: The barrier property is better than that of single-layer plastic packaging film, which can block the entry of oxygen and water vapor and has stronger light-shielding properties.
  • Paper: Some countries that implement the “plastic ban” will use paper to make packaging bags, which are green, environmentally friendly, and recyclable.
  • Multilayer composite materials: Multilayer composite materials combine the characteristics of different materials and combine them into a film to achieve a better barrier effect. For example, for the packaging of coffee beans, to better preserve the quality and flavor of coffee, we generally need to add an extra layer of aluminum to the composite material, such as PET/Al/PE or BOPP/Al/CPP, which not only plays a better barrier role but also prevents coffee from deteriorating when it gets wet.

Composite Material Combination

  • PET/FOIL/PE: Provides good barrier, sealing and mechanical properties.
  • PET/VMPET/PE: VMPET stands for aluminum-coated polyester film, which provides metallic luster while maintaining certain barrier properties.
  • PE/PE: Simple and economical, suitable for products that do not require high barrier properties.
  • PET/PE or NY/PE: Provides good transparency or strength, suitable for products that do not require extremely high barrier properties.

Special Functional Materials

  • Antistatic materials: Used for products that require antistatic protection, such as electronic parts.
  • UV-resistant materials: Used for products that need to be protected from UV damage, such as certain cosmetics or medicines.
  • Moisture-proof materials: Used for products that require strict control of humidity, such as certain foods or medicines

Printing Technology and Surface Printing of Stand Up Pouches

  • Printing technology: including gravure printing, screen printing, offset printing digital printing, etc. You can choose the corresponding printing technology according to the printing effect you want to achieve. Customized printing can achieve better brand promotion.
  • Surface treatment: such as lamination, hot stamping, UV varnish, etc., can improve the beauty and personality of the packaging.
  • Printing technology: including gravure printing, screen printing, offset printing digital printing, etc. You can choose the corresponding printing technology according to the printing effect you want to achieve. Customized printing can achieve better brand promotion.

Design and Function of Stand Up Pouches

The design of each packaging bag should not only consider the appearance, but also the practicality, and stand up pouches are no exception. For example: How can a bag stand steadily after being filled with things? We can design a bottom for it. How can the bag be sealed again after being opened? You can add a zipper on the top to prevent the product from being quickly oxidized and deteriorated. For the bag of coffee beans, how can the air inside the bag be expelled after being sealed? Then we can install a one-way air valve on the bag.

Application Fields of Stand Up Pouches:

Due to their uniqueness and advantages, stand up pouches are widely used in many fields.

  • Food packaging: Applicable to almost all kinds of food, such as snacks, coffee, tea, etc.
  • Beverage packaging: Applicable to juice, powdered beverages, etc., easy to transport and strong softness.
  • Daily chemical products: Used for skin care products, washing products, etc., saving packaging costs compared to hard packaging
  • Other products: Such as electronic products, medical fields, etc., provide additional protection for them.

Future Development of Stand Up Pouches:

  • Material cost: The cost of environmentally friendly composite packaging materials is relatively high, which may affect the cost of packaging
  • Environmental protection: Although environmental protection has been advocated and a series of environmentally friendly materials have been developed, the recycling and disposal of stand up pouches is still a problem.

With the continuous emergence of new materials and technologies, stand up pouches in the future will be more intelligent and environmentally friendly. For example, the application of intelligent packaging technology can achieve product tracking and tracing and improve food safety.

In addition, as consumers pay more and more attention to sustainability, the use of environmentally friendly materials and recyclable designs will become the mainstream trend of future development.

As a flexible packaging solution, stand up pouches can not only meet the packaging needs of products but also adapt to the diverse needs of the market and consumers. With the advancement of technology and the enhancement of environmental awareness, stand-up pouches will play a greater role in the packaging industry in the future.
