EnglishThis Heat Seal Flexible Shiny Metallic Flat Pouch is typically made from a multi - layer composite material. The outer layer usually consists of a high - quality polyester film, which provides the shiny metallic appearance and good printability. The middle layer often includes an aluminum foil layer, offering excellent barrier properties against moisture, oxygen, light, and odors. The inner layer is generally a heat - sealable polypropylene or polyethylene film, enabling easy sealing during the packaging process.
Superior Barrier Properties: The aluminum foil layer effectively blocks out external elements such as moisture, oxygen, and light, ensuring the product inside remains fresh and protected for an extended period. This makes it ideal for packaging food items, pharmaceuticals, and other products sensitive to environmental factors.
Attractive Appearance: The shiny metallic surface gives the pouch a luxurious and eye - catching look, enhancing the product's shelf appeal and making it stand out among competitors. It can attract customers' attention and increase the perceived value of the packaged product.
Flexibility and Durability: The flexible nature of the pouch allows for easy handling, storage, and transportation. It can conform to the shape of the product, reducing wasted space. Despite being flexible, it is also durable enough to withstand normal handling and prevent punctures or tears.
Heat - Sealable: The heat - sealable inner layer ensures a secure and tight seal, preventing leakage and maintaining product integrity. This makes the packaging process efficient and reliable, suitable for various automated packaging lines.
Customizable: It can be customized in terms of size, shape, printing, and additional features like zippers, tear - notches, or hang - holes, meeting the specific needs of different products and branding requirements.
