This innovative packaging form is not only beautiful and practical, but also shows extraordinary ability in protecting product quality. And all of this is inseparable from the multilayer composite materials used in stand-up pouches.
As the name suggests, the multilayer composite materials of stand-up pouches are made of a variety of materials with different functions stacked and composited. This design is not a simple stacking, but is carefully selected and scientifically proportioned to achieve the best packaging effect. Each layer of material plays a specific role, and together they build an indestructible barrier to provide all-round protection for the product.
First of all, these materials have excellent mechanical strength. Stand-up pouches need to withstand a certain amount of weight and pressure to ensure that they do not deform or break during transportation and storage. The high-strength layers in the multilayer composite materials, such as polyester (PET) and nylon (Nylon), provide a solid skeleton for stand-up pouches, enabling them to easily cope with various challenges.
However, mechanical strength alone is far from enough. The real charm of stand-up pouches lies in their excellent barrier properties. The barrier layers in these multi-layer composite materials, such as aluminum foil and polyvinyl alcohol (PVA), can effectively block factors such as oxygen, carbon dioxide, and moisture that may affect product quality. Oxygen is the main culprit for the deterioration of many products. It can accelerate the oxidation reaction of food, leading to the loss of nutrients and the deterioration of taste. Carbon dioxide may change the acid-base balance of the product and affect its stability. Moisture is a hotbed for the growth of microorganisms, which can easily lead to the corruption and deterioration of the product. By blocking these unfavorable factors, the self-supporting bag creates a stable and safe storage environment for the product, effectively extending the shelf life of the product.
In addition, the multi-layer composite material also gives the self-supporting bag good weather resistance and chemical resistance. Whether it is high temperature, low temperature or humid and dry environment, the self-supporting bag can maintain its stable performance and will not affect the quality of the product due to changes in external conditions. At the same time, it can also resist the erosion of various chemicals to ensure that the product is not contaminated.
The multi-layer composite material used in the self-supporting bag is the cornerstone of its excellent performance. These materials not only give the self-supporting bag good mechanical strength, but also show extraordinary advantages in barrier properties, weather resistance, chemical resistance, etc. Together, they build an indestructible barrier, providing a stable and safe storage environment for products, effectively ensuring product quality and safety. In the future, with the continuous advancement of material science and continuous innovation in packaging technology, we have reason to believe that the multi-layer composite materials of stand-up pouches will become more advanced and more complete, providing better packaging solutions for products in more industries.
