Complex membrane seed packaging

Seeds are a sensitive product that needs to be protected during storage. Seeds are very "fragile" and easily damaged by factors from the surrounding environment. So they need to be preserved in high-class packaging, made from more special materials. Seed packaging must be moisture-proof, insect-proof, or sun-damaged. The most important thing is to avoid damaging the seed.

To do this, the packaging must combine several layers of materials. Each class has its function. The combination brings out the most outstanding advantages of each material in the structure of the packaging. This type of packaging is called composite film packaging.

The composite film, also known as multilayer film, is a combination of the superior properties of each different single film to create a perfect packaging structure that meets most of the product requirements that it requires. Contains.

Structural characteristics of seed packaging film

Aluminum Film (AL)

Aluminum foil (Al foil) is a form of aluminum that is laminated into aluminum foils with a thickness of 0.004mm (4 mics) or more and not exceeding 0.2mm (200 mics). Depending on different uses, aluminum films have different thicknesses. The aluminum film used in film lamination has a common thickness of 6mic, 7mic, and 9mic… An aluminum film thickness of 25mic or more can completely prevent air and water vapor. Thinner aluminum films have lower permeability.

Aluminum films are widely used for packaging, as they can easily be converted into thin films, bags, rolls, or packages. The aluminum foil acts as a barrier against light and air, preventing odors, moisture, and bacteria. Therefore, aluminum film is widely used as packaging for food, and pharmaceutical products, containing products with long shelf life such as drinks or milk, etc., without needing to be stored in the refrigerator. Aluminum foil is also used in compound film seed packaging because of this special feature.
