One side of the Aluminized Packaging Bags is a transparent film, and the other side is an opaque film of aluminized or aluminum foil. Its material composition usually includes PET+PE (vacuum film) or PE+PA (nylon vacuum film) as the transparent side, while the other side is composed of PET+AL+PE (aluminum foil) or PET+AL+CPP (high temperature resistant aluminum foil) or PET+aluminized film+PE.

Features and uses

High barrier property: Yin-Yang aluminized bags can isolate oxygen, water vapor, light, etc., thereby extending the shelf life of products. This feature makes it particularly suitable for packaging foods rich in moisture and sugar, such as dried fruits, to prevent oxidation and deterioration.

Beautiful and elegant: Yin-Yang aluminized bags have a metallic luster, which enhances the visual grade of the product, attracts consumers' attention, and increases the attractiveness of the product.

High temperature resistance and high heat sealing strength: Able to withstand high temperatures without deformation or rupture, ensuring the sealing of the package.

Lightweight and soft: Easy to transport and carry, reducing transportation costs and storage space.

‌High transparency‌: It allows consumers to clearly see the products in the package and increase the display effect‌.

Application scenarios

Yin-yang aluminized bags are widely used in various packaging occasions that require high barrier properties, such as dried fruits, tea, powder, electronic components, etc. Its good printability and flexibility make the packaging more attractive and beautiful, suitable for gift packaging and high-end commodity packaging‌.

2. Yin-yang gold-plated bags

‌ is a special packaging material characterized by a transparent film on one side and an opaque film with aluminum or aluminum foil on the other side. This material usually consists of PET+PE (vacuum film) or PE+PA (nylon vacuum film) on the transparent side, and PET+AL+PE (aluminum foil) or PET+AL+CPP (high temperature resistant aluminum foil) or PET+aluminized film + PE on the other side‌.

Uses and characteristics of Yin-yang gold-plated bags

‌Good sealing performance‌: Yin-yang gold-plated bags have good sealing performance and can effectively prevent the intrusion of external air and moisture.

‌Good puncture resistance‌: This material has a high puncture resistance strength and can protect the items in the package from damage.

‌Odorless‌: The material itself has no odor and will not have adverse effects on the products in the package.

‌Good light-proof performance‌: The opaque side can effectively block light and protect light-sensitive products.

‌Wide range of applications‌: Suitable for cosmetics, facial masks, medicinal materials, various solutions, food, PC boards, IC integrated circuits, optical drives, hard drives, electronic components, welding materials, electronic products, etc. ‌.

Manufacturing process and application scenarios of Yin-Yang gold-plated bags

The manufacturing process of Yin-Yang gold-plated bags includes multi-layer composite technology, which forms the desired characteristics by laminating different materials together. Its application scenarios are very wide, especially in packaging that requires good display effects and light-proof protection. For example, in food packaging, the transparent side can display the product, while the opaque side can effectively block light and extend the shelf life of the product.
