As an advanced packaging material, stick packaging composite film is widely used in the packaging of powder products, such as dietary supplements, milk powder, instant coffee, etc. These products are sensitive to air and are easily affected by oxygen, moisture and microorganisms and deteriorate. Therefore, stick packaging composite film effectively isolates air and protects the freshness and quality of powder products through its unique design and performance.Stick packaging composite film is usually made of multiple layers of materials, each of which has a specific function. Among them, the barrier layer is the key, which is usually made of high barrier materials such as aluminum foil, EVOH (ethylene-vinyl alcohol copolymer) or vapor-deposited film. These materials have extremely low oxygen and water vapor permeability and can effectively block the intrusion of air and moisture. Through a precise composite process, the barrier layer is closely combined with other functional layers (such as heat sealing layer, antistatic layer, etc.) to form a complete and efficient protective barrier.In addition to the barrier layer, stick packaging composite film also uses other technologies to enhance its air isolation ability. For example, coating the surface of the film with a layer of polyisobutylene or other waterproof coating can further improve its moisture resistance. At the same time, the internal structure of the film is also carefully designed, and by introducing structures such as micropores or airbags, the thickness and strength of the film are increased, thereby improving its barrier performance to gas.In practical applications, stick packaging composite film seals the powder product inside the package through heat sealing technology. The heat sealing layer is usually made of materials with excellent heat sealing and bonding properties to ensure that the package can fit tightly during the heat sealing process to avoid leakage. At the same time, the heat sealing layer can also provide additional barrier properties to further enhance the sealing of the package.While isolating the air, the stick packaging composite film also has good transparency and printing properties. This allows consumers to intuitively see the products in the package and enhance their desire to buy. At the same time, by printing exquisite patterns and texts, the stick packaging composite film can also enhance the brand image and market competitiveness of the product.In summary, the stick packaging composite film effectively isolates the air and protects the freshness and quality of the powder product through its unique design and performance. In future development, with the continuous advancement of material science and packaging technology, the performance of stick packaging composite film will be further improved, providing a more efficient and environmentally friendly solution for the packaging of powder products.As an advanced packaging material, stick packaging composite film is widely used in the packaging of powder products, such as dietary supplements, milk powder, instant coffee, etc. These products are sensitive to air and are easily affected by oxygen, moisture and microorganisms and deteriorate.
