In the ever-evolving wave of innovation in the packaging industry, side-sealed pouches are gradually becoming the market's favorite due to their unique advantages and wide range of applications.

Structure and Characteristics of side-sealed pouches

As the name suggests, side-sealed pouches have a sealed edge structure on the side of the bag. This structure provides the bag with excellent stability and a larger capacity. Generally, the side-seal edge of side-sealed pouches can increase the bag's width, allowing it to maintain a good shape after filling with products and preventing deformation. Moreover, compared to ordinary packaging bags, side-sealed pouches can hold more products under the same plane size, improving packaging efficiency. At the same time, side-sealed pouches are typically made of multilayer composite materials, such as PET or BOPP on the outer layer, which provides good printability and gloss, a barrier layer like aluminum foil or VMPET in the middle that can effectively block oxygen, moisture, and light, and an inner layer of LLDPE that has good heat-sealing performance and flexibility, ensuring the bag can safely encapsulate products.

Applications of side-sealed pouches

* Food Industry: Side-sealed pouches are widely used for packaging coffee beans, tea, and other perishable goods that require superior freshness preservation. Their barrier properties effectively retain flavor and block external contaminants. Products like grains, nuts, and candies also benefit from side-sealed pouches due to their high capacity and stable shelf presence, enhancing both usability and visual appeal.

* Chemical Industry: Powdered or granulated chemicals, including fertilizers and pesticides, leverage the durability and sealing integrity of side-sealed pouches to prevent leaks, ensuring safety during transport and storage.

* Daily Necessities Industry: Everyday products such as laundry detergents, fabric softeners, and smaller household items (e.g., toothpaste and toothbrushes) also use side-sealed pouches. These pouches are designed to stand out on shelves, attract consumers, and offer convenient portability and usage.
