Soft tempered aluminum foil is annealed during the manufacturing process, giving it excellent formability and ductility. Soft temper tempering makes the foil easy to work on the lamination line and allows it to form strong adhesion bonds when laminating to a variety of substrates. HTMM's Soft Tempered Foil Aluminum Roll 8079 Alloy undergoes rigorous quality control and testing to ensure these properties are optimized for reliability in lamination.
Excellent formability
The soft temper annealing process produces a highly formable malleable cast foil during lamination. Soft Tempered 8079 aluminum foil from HTMM can be strongly thermoformed around curves and contours without any cracks or splits in the foil. This makes it ideal for applications requiring tight packaging, such as candy packaging.
The superior formability of soft tempered aluminum foil 8079 also allows for complex designs. Lamination converters can convert foil into complex shapes with sharp angles and details. This expands innovation possibilities for products such as flexible food packaging, pouches and pharmaceutical secondary packaging.
The soft and pliable nature of the foil means it hugs the substrate smoothly without any wrinkles, even when stacked in multiple layers. This results in a beautiful finished lamination free of defects.
Robust ductility
Another key property of soft tempered aluminum foil is its high ductility. Ductility refers to the ability of a material to undergo significant plastic deformation before fracture.
HTMM's soft tempered aluminum foil 8079 has been tested to consistently achieve over 35% elongation per ASTM standards. This level of ductility allows the foil to be stretched and bent repeatedly without damage.
The strong ductility of Soft Tempered Food Packing 8079 Aluminum Foil makes it a very durable laminated wire. It can undergo painstaking processing such as drawing, creasing, scoring and die-cutting while still maintaining its integrity. Even after multiple deformations, the foil undergoes minimal work hardening.
This maximizes lamination equipment uptime because the soft-tempered foil is less likely to break or tear during high-speed operations. Reduced downtime for repairs and maintenance, increased lamination throughput and efficiency.
The ductility also extends the life of the finished product. Soft tempered aluminum foil 8079 reliably withstands the stresses of bending, folding and distribution and use without damaging the lamination bond.
Excellent adhesion
Good adhesion is critical to the aluminum foil used for lamination. HTMM's soft tempered aluminum foil 8079 provides best-in-class adhesion due to its smooth, defect-free surface and optimal annealing.
The soft tempering process produces a virtually pinhole-free foil surface. This provides a larger contact area for the adhesion promoter and adhesive.
In HTMM's state-of-the-art production facility, soft tempered aluminum foil 8079 also undergoes strict quality control to maintain ultra-low levels of surface oxides, silicones and oils that can hinder bonding.
As a result, the foil achieves reliable, uniform adhesion to a variety of substrates such as paper, polymer films and laminating resins. According to FINAT standards, bond strength tests are consistently above 30N/15mm - well above the industry requirement of 15N/15mm.
This ensures that laminate converters can rely on void- and bubble-free components time and time again. The strong adhesion also enables excellent workability in wet glue, extrusion coating and other application lines for finished laminated products such as labels and heat transfers.
Excellent printability
Premium grade soft tempered foils such as HTMM's Soft Tempered Aluminum Foil 8079 also offer printing advantages. Its smooth, refined surface accepts brilliant applications of a variety of printing inks, including direct printing onto foil layers. Whether on narrow web, wide web or digital presses, soft tempered foils deliver high fidelity color and fine detail. It handles rigorous printing operations smoothly and without breakage.
After printing, the foil maintains its ink adhesion through lamination, slitting, die-cutting and other conversion steps. The finished laminate retains its vibrant, crisp printed graphics throughout its ultimate service life. This maximizes the impact of graphics and branding on products. It also supports innovations such as integrated digital printing and conversion to mass customization solutions such as variable data security labels.
Rigorous testing and certification
As a leading manufacturer, HTMM's Customized 8079 O Lamination Aluminum Foil undergoes strict quality assurance protocols to ensure consistent quality performance. In addition to regular indicator monitoring, aluminum foil also undergoes:
