2 Foil Materials
This foil material features a reinforced PA/AL/LDPE structure, offering excellent protective performance for seafood preservation powder packaging. The multi-layer composition provides a strong barrier against moisture, oxygen, and light, helping maintain the freshness, flavor, and nutritional quality of the product. The smooth surface ensures a premium visual appearance while supporting clear and detailed graphic printing, making your packaging both functional and visually appealing.
Let’s first get a further understanding of each substrate layer material.
PA, short for Polyamide, is a high performance material widely used in flexible packaging structures. It is commonly applied as a functional barrier layer, helping to enhance the overall strength and protective performance of the packaging. With its dense and stable molecular structure, PA plays an important role in preserving product quality and extending shelf life, especially for products that are sensitive to oxygen and external impact.
One of the key advantages of PA is its excellent oxygen and odor barrier properties, which help slow down oxidation and maintain freshness and original flavor. PA also offers outstanding mechanical strength, with strong resistance to puncture and tearing, providing reliable protection during transportation and handling. In addition, PA performs well under low temperature conditions, making it suitable for refrigerated and frozen applications. Its good compatibility with other materials allows flexible lamination structures to meet different packaging requirements. PA is also chemically stable and resistant to oils, making it a versatile choice for a wide range of food and non food packaging uses.
AL, short for Aluminum foil, is a widely used barrier material in flexible packaging applications. It is typically incorporated as a core barrier layer to provide maximum protection against external factors. With its dense and non porous structure, Al plays a critical role in preserving product freshness, stability, and shelf life, especially for products that are highly sensitive to light, oxygen, and moisture.
One of the main advantages of Al is its excellent barrier performance. It offers near complete protection against oxygen, moisture, light, and aroma transfer, effectively preventing oxidation and flavor loss. Al also helps maintain product integrity by shielding contents from environmental changes. In addition, it contributes to the overall strength and dimensional stability of the packaging when laminated with other materials. Its high temperature resistance makes it suitable for applications requiring thermal processing. Due to its reliable barrier properties and wide compatibility in laminated structures, Al is a preferred material for high protection packaging needs.
LDPE, short for Low Density Polyethylene, is a flexible and widely used material in packaging applications. It is commonly applied as a sealing or inner layer in laminated structures, providing softness, flexibility, and reliable heat sealing performance. LDPE helps ensure package integrity while offering a smooth and consistent contact surface for the product.
One of the key advantages of LDPE is its excellent heat sealability, allowing strong and stable seals even at lower sealing temperatures. It also offers good flexibility and toughness, making the packaging resistant to cracking or stress during handling. LDPE has reliable moisture resistance, helping protect products from humidity. In addition, it is chemically stable and safe for direct food contact, making it suitable for a wide range of food and non food packaging applications. Its good processability and compatibility with other materials make LDPE an essential component in many flexible packaging structures.

In our manufacturing plant, we take serious measures to achieve high color fidelity and consistency for repeated printed orders, and here we are going to give a basic introduction.
a. Color Analyzer
Color Analyzer Checking
This color analyzer is one of the auxiliary tools in our system to achieve the highest standard for color fidelity. The eXact Advanced doesn’t just validate the color of CMYK and spot color inks, it can simultaneously measure four M modes to visualize the spectral reflectance of a substrate or ink, measure the concentration of a specific ink, and measure the difference of a substrate or ink over white and over black.
b. Pantone Color Code
Pantone-color-print-examine-coffee-bag
Pantone color guide would be so helpful to locate a specific color for the pring service supplier and the customers, especially there is a large area printed in single Pantone color. For many Pantone colors, the accurateness may be influenced by the printer, paper substrate and environmental factors when it is printed onto physical photo paper. We will locate the Pantone Color Code with the customers in their artwork design before the order is put into produce.
c. Physical Printed On Photo Paper
Print-proofs-printed-on-photopaper
The computer files such as JPG, PDF, PSD, AI etc can not be taken as the guide to determine the color in print produce, as they present the colors through electronic screening devices. And different electronic screens may be set in different parameters by the various manufacturers, which will inevitably interfere with the colore presentation. Artwork can only be a reliable guide when printed on physical substrate, with the most common photo paper applied.
