8079 Aluminum Foil for Flexible Packaging

8079 aluminum foil is an 8xxx-series alloy—composed primarily of aluminum, حديد, and silicon—frequently used in high-barrier composite structures for flexible packaging. It is characterized by its superior flexibility, استطالة, ثقب مقاومة, وقابلية المعالجة, making it well-suited for downstream operations such as printing, adhesive coating, تصفيح, slitting, and bag manufacturing.

In sectors including food, الأدوية, طعام الحيوانات الأليفة, قهوة, dairy, بهارات, personal/household care products, and industrial packaging, 8079 aluminum foil serves as a barrier layer. It helps protect contents by minimizing the impact of oxygen, بخار الماء, ضوء, والروائح. The actual barrier performance depends on factors such as foil thickness, pinhole density, the specific composite structure, the quality of edge sealing, and the environment in which the packaging is used.

Material Characteristics of 8079 ورق ألومنيوم

8079 aluminum foil is typically supplied in an “ال” (fully annealed/soft) لين، لطف، هدأ, which facilitates lamination and packaging formation. Compared to some types of pure aluminum foil, ال 8079 alloy maintains better toughness even at thinner gauges. بالتالي, it is frequently chosen for flexible packaging applications that require high resistance to flexing, creasing, and cracking, as well as strict control over pinholes.

Key performance of Haomei 8079 flexible packaging aluminium foil يشمل:

ليونة جيدة, making it suitable for lamination, النقش, قابلة للطي, and pouch making;

Strong puncture resistance, ideal for packaging items with sharp edges or granular contents;

High barrier properties against water vapor, أكسجين, زيوت, وضوء;

A surface suitable for printing, طلاء, and dry lamination;

The aluminium foil is non-toxic and odorless; ومع ذلك, compliance for food or pharmaceutical contact must be verified based on the final packaging system and the regulations of the target market.

Common Specifications of 8079 Flexible Packaging Aluminum Foil:

For flexible packaging, 8079 aluminum foil is typically produced in thicknesses ranging from 6 إلى 20 ميكرون, with 6 μm, 7 ميكرون, 9 ميكرون, 10 ميكرون, 12 ميكرون, 15 ميكرون, و 18 μm being the most common. Thicker gauges may be selected for applications requiring higher puncture resistance, a lower pinhole count, or greater stiffness; ومع ذلك, the specific thickness must be compatible with the packaging structure and processing equipment.

Master rolls can be supplied in widths tailored to the requirements of laminating machines, printing presses, or slitting machines, typically ranging from 200 إلى 1300 مم. Standard core inner diameters are 76 مم, 150 مم, أو 152 مم. Specific requirements regarding roll weight, القطر الخارجي, and the allowable number of splices should be clearly defined at the time of ordering.

Typical Laminated Packaging Structures

8079 aluminum foil is rarely used on its own to form packaging pouches; instead, it is laminated with plastic films, ورقة, or coating materials. Common industry structures include:

حيوان اليف / AL / PE: Suitable for general food products, التوابل, and personal care/household products;

حيوان اليف / AL / CPP: Suitable for certain high-temperature retort or heat-resistant sealing applications (temperature resistance depends on the specific films and adhesives used);

بوب / AL / PE: Frequently used for snacks, dry foods, and standard laminated pouches;

ورقة / AL / PE: Used for paper-aluminum laminates, as well as certain beverage and food packaging;

حيوان اليف / AL / السلطة الفلسطينية / PE: Suitable for packaging that requires high puncture resistance and mechanical strength. The design of a composite structure should be determined by considering the characteristics of the contents, shelf-life requirements, filling methods, sterilization conditions, transportation environment, and local regulations.
