Aluminum foil packaging film is a flexible packaging material made of high-purity aluminum foil as the barrier layer, composite with multiple layers of materials such as polyester (PET), polyethylene (PE), and nylon (PA). Its core function is to utilize the density and light-blocking properties of the aluminum foil layer to block external factors such as oxygen, moisture, odors, and light, thereby effectively extending the product's shelf life. Through multiple processes including surface printing, lamination, curing, and slitting, it forms a packaging material with excellent appearance and mechanical properties. As an important category of plastic flexible packaging, aluminum foil composite film not only possesses a metallic texture and high-end visual effect in appearance, but also embodies a comprehensive balance between sealing and hygiene safety, providing a high-performance solution for the modern packaging industry.

1. High Barrier Properties:

Printing Composite Aluminum Foil Packaging Film uses 6–9 μm thick high-purity aluminum foil, laminated to form an extremely low air permeability barrier layer. Oxygen permeability (OTR) is less than 0.01 cm³/m²·24h, and water vapor permeability (WVTR) is less than 0.01 g/m²·24h, almost completely blocking the penetration of air, moisture, and light, preventing oxidation or moisture absorption of the contents. This property makes it an ideal outer packaging material for easily oxidized and hygroscopic products, especially outstanding in vacuum and nitrogen-filled packaging.

2. High Mechanical Strength:

Through the synergistic structure of the PET and PA layers, the overall tensile strength of the film reaches ≥70 N/15 mm, and the peel strength is ≥4 N/15 mm. It remains stable and unbreakable even under automated high-speed packaging machine conditions (300 times/minute). Its excellent puncture resistance can withstand needle puncture loads up to 12 N, making it particularly suitable for packaging and transporting items containing hard particles or powders.

3. Stable Heat-Sealing Performance:

The inner layer of the Aluminum Foil Packaging Film is made of high-density PE or high-temperature resistant CPP material, with a heat-sealing temperature range of 110–135 ℃, ensuring a strong and uniform seal. Whether sealed at room temperature, heat-pressed, or vacuum-packed, it maintains excellent sealing performance. Tested on Zhongxing's production line, the film's heat-sealing strength is ≥40 N/15 mm, ensuring no leakage of contents during transportation, stacking, and in high-humidity environments.

4. High Printability and Lamination Suitability:

The Aluminum Foil Packaging Film uses a corona-treated PET surface layer with a stable surface tension of 38–42 dyn, suitable for gravure, flexographic, or digital printing. Ink adheres firmly, with saturated and vibrant colors, enabling 8–10 color precision printing. After printing and lamination, the film surface is smooth and has high gloss (≥90 GU), effectively enhancing the brand packaging's recognizability and aesthetics, meeting the packaging needs of high-end consumer goods.

5. Environmental Protection and Safety Compliance:

Aluminum Foil Packaging Film complies with GB 9685, GB/T 10004, FDA 21 CFR 177.1520, and EU 10/2011 standards, and is free of BPA, phthalate plasticizers, and heavy metals. Zhongxing employs a solvent-free lamination process, resulting in low VOC emissions. The product passes RoHS, REACH, and SGS testing, meeting the safety requirements of food, pharmaceutical, and infant product packaging, reflecting the company's green manufacturing philosophy.

1. Food and Beverage Packaging:

Aluminum Foil Packaging Film is widely used in high-end food packaging such as coffee beans, milk powder, nuts, baked goods, seasonings, instant soup packets, and infant formula. Its excellent barrier properties prevent oxidation, moisture absorption, and aroma loss, preserving the original flavor and nutrition of the food. The light-blocking properties of the aluminum foil layer effectively block ultraviolet rays, extending shelf life and improving shelf display. Zhongxing's high-precision printing process can also achieve visible windows or partial matte designs.

2. Pharmaceutical and Health Product Packaging:

Aluminum Foil Packaging Film is suitable for powders, capsules, granules, medical reagents, and other products requiring airtight moisture protection. The packaging film has extremely high cleanliness and sterility, meeting GMP standards for pharmaceutical packaging. It has strong chemical resistance, can withstand contact with substances within a pH range of 2–10, and does not leach harmful components. Zhongxing offers customizable antistatic, anti-counterfeiting printing, and UV-resistant composite films, providing comprehensive protection for the pharmaceutical industry.

3. Cosmetics and Daily Chemical Packaging:

Aluminum Foil Packaging Film is widely used in mask pouches, shampoos, conditioners, skin creams, and cosmetic sample packaging. The high-gloss aluminum layer provides a metallic visual effect, showcasing a high-end brand image. The composite film has excellent sealing and leak-proof properties, effectively preventing the evaporation or oxidation of essence ingredients. Its strong printability makes it suitable for small-batch, multi-style OEM packaging customization.

4. Industrial and Electronic Product Packaging:

Aluminum Foil Packaging Film exhibits excellent moisture-proof, anti-static, and anti-corrosion properties in the fields of chemical powders, solder pastes, electronic components, moisture-proof capacitors, and semiconductor chips. The conductive properties of the aluminum foil layer reduce static electricity buildup, preventing damage to delicate electronic components. Zhongxing's industrial-grade packaging film has passed a 48-hour aging test under conditions of 80℃ temperature and 90% humidity, demonstrating stable and reliable performance, suitable for export transportation environments.
