8079 aluminum foil is an 8xxx-series alloy—composed primarily of aluminum, железо, and silicon—frequently used in high-barrier composite structures for flexible packaging. It is characterized by its superior flexibility, удлинение, устойчивость к проколам, и обрабатываемость, making it well-suited for downstream operations such as printing, adhesive coating, слоистость, slitting, and bag manufacturing.
In sectors including food, фармацевтические препараты, Корм для животных, кофе, dairy, приправы, 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, водяной пар, легкий, и запахи. 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.

8079 aluminum foil is typically supplied in an “О” (fully annealed/soft) характер, which facilitates lamination and packaging formation. Compared to some types of pure aluminum foil, в 8079 alloy maintains better toughness even at thinner gauges. Следовательно, it is frequently chosen for flexible packaging applications that require high resistance to flexing, creasing, and cracking, as well as strict control over pinholes.
Хорошая пластичность, making it suitable for lamination, чеканка, складной, and pouch making;
Strong puncture resistance, ideal for packaging items with sharp edges or granular contents;
High barrier properties against water vapor, кислород, масла, и свет;
A surface suitable for printing, покрытие, and dry lamination;
The aluminium foil is non-toxic and odorless; тем не мение, compliance for food or pharmaceutical contact must be verified based on the final packaging system and the regulations of the target market.
For flexible packaging, 8079 aluminum foil is typically produced in thicknesses ranging from 6 к 20 мкм, with 6 μm, 7 мкм, 9 мкм, 10 мкм, 12 мкм, 15 мкм, а также 18 μm being the most common. Thicker gauges may be selected for applications requiring higher puncture resistance, a lower pinhole count, or greater stiffness; тем не мение, 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 к 1300 мм. Standard core inner diameters are 76 мм, 150 мм, или 152 мм. Specific requirements regarding roll weight, внешний диаметр, and the allowable number of splices should be clearly defined at the time of ordering.
8079 aluminum foil is rarely used on its own to form packaging pouches; instead, it is laminated with plastic films, бумага, or coating materials. Common industry structures include:
ПЭТ / Алабама / PE: Suitable for general food products, приправы, and personal care/household products;
ПЭТ / Алабама / CPP: Suitable for certain high-temperature retort or heat-resistant sealing applications (temperature resistance depends on the specific films and adhesives used);
БОПП / Алабама / PE: Frequently used for snacks, dry foods, and standard laminated pouches;
Бумага / Алабама / PE: Used for paper-aluminum laminates, as well as certain beverage and food packaging;
ПЭТ / Алабама / А / 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.
