8079 H14 Heat-Sealable Aluminum Foil
In the sectors of food, Фармацевтика, pet food, and daily chemicals, the barrier properties, heat-sealing stability, and mechanical reliability of packaging materials directly determine product shelf life, transportation safety, and end-user quality. As a representative product of the 8XXX series high-end alloy aluminum foils, 8079 H14 Heat-Sealable Aluminum Foil stands out with balanced mechanical properties, ultimate barrier protection, and stable heat-sealing adaptability. It serves as the preferred substrate for high-speed automated packaging lines and the core functional material for high-end composite soft packaging, offering significant advantages over traditional 8011 және 1235 сериясы.
Мен. Core Product Definition
8079 H14 Heat-Sealable Aluminum Foil is a functional aluminum foil made from an 8079 aluminum alloy base and processed via the H14 semi-hard temper. It is specifically engineered for composite heat-seal packaging.
H14 мінез: The Golden Balance
The H14 semi-hard state is the key to its performance, achieving a perfect equilibrium between material strength and processing toughness. It effectively avoids the insufficient strength and vulnerability to breakage found in soft-tempered foil (O-quck), while solving the poor processability and unstable heat sealing often seen in full-hard temper foil.
Microstructural Advantages
Салалық стандартпен салыстырғанда 8011 легирленген фольга, 8079 features a superior iron content range, a lower pinhole rate, and a more uniform microstructure. It possesses stronger puncture resistance, tear strength, және ерекше кедергі қасиеттері, making it the exclusive choice for high-end, high-barrier packaging scenarios.

В. Жиі қойылатын сұрақтар (Жиі қойылатын сұрақтар)
Q1: мүмкін 8079 H14 be used for direct heat sealing?
Ешқандай. This product is a base foil and does not have a built-in heat-seal layer. It must be laminated with films like PE, Кәсіпкер, or VMCPP to achieve a stable seal. It serves as the core middle layer of multi-layer packaging.
Q2: Is it suitable for vacuum and nitrogen-flushed packaging?
Иә. Its dense structure and high mechanical strength effectively maintain a sealed environment, preventing gas penetration or bag inflation.
Q3: Does it support customization?
Иә. We offer full-spec customization for thickness (0.006–0.050mm), ені, and surface status (single/double light, coating-grade, т.б.).
