Flexible Food Packaging With Aluminum Foil 7 Micron
As a highly formable yet barrier material, 7 micron aluminum foil is well-suited for flexible food packaging applications. The ultra-thin gauges allow for downgauging and lightweight packaging designs while still providing the key functional benefits of aluminum. Due to its composition of 12% silicon and trace amounts of magnesium, alloy 1235 aluminum foil 7 micron exhibits excellent resistance to corrosion, is odorless and tasteless. These attributes make it fully compliant for direct food contact use.
The gauge of 7 microns offers an optimal balance between packaging performance and material cost savings vs thicker foils. At this thickness, aluminum foil 7 micron still maintains excellent gas and moisture barrier properties to protect product freshness. It is impermeable to air and water vapor, which helps extend shelf-life of packaged foods. The jumbo roll width of 1220mm supports high-speed, automated foil printing and lamination lines commonly used in the food and pharmaceutical industries.
Key advantages of using aluminum foil 7 micron for flexible food packaging include:
Lightweight and downgauge packaging designs
Superior barrier to gases, moisture, greases and flavors
Reclosability and resealability
Cost-effective material at 7 micron gauge
Compliant for direct food contact and FDA approved
Wide roll width of 1220mm for high-speed conversion lines
Common flexible food packaging applications that benefit from aluminum foil 7 micron alloy 1235 width 1220 include:
Confectionery wrappers
Baked goods trays and sleeves
Snack and cracker pouches
Fresh meat, poultry or seafood wraps
Cheese slices or shreds
Powdered drink packets
Frozen food containers or pouches
Pharmaceutical and nutritional supplement foils
With increasing global demand for convenient, on-the-go packaging lightweight aluminum foil rolls are indispensable to the flexible packaging industry. Manufacturers favor customized 7 micron specifications that deliver the right performance at optimal costs.
Aluminum Foil Factory Made Jumbo Rolls
For flexible packaging and other industrial converting lines, pre-slit and factory-made aluminum foil jumbo rolls offer key productivity advantages over sheet or cut-to-size foil materials. The 1220mm width integrated with 7 micron gauge aluminum foil alloy 1235 supports high-speed, automated processing on roll-to-roll equipment common in volume manufacturing environments.
Some key benefits of using factory produced aluminum foil jumbo rolls in production include:
Consistent roll quality ensures smooth conversion throughput
Precise width slitting for optimum yield and material savings
Large roll diameters provide extended run times vs small rolls
Integrated with required specification - 7um x 1220mm
Tailored logistics for jumbo rolls like customizable cores
Sustainable packaging reduces material handling and waste
Tighter thickness tolerance vs cut-to-size materials
Customizable logistics like smaller inner diameter cores
Cost-effective solution for high-volume production lines
Aluminum foil rolls factory made to specification eliminate inconsistencies associated with converted sheet or hand-slit materials. Their compatibility with automated machinery is indispensable for the type of high-speed packaging lines common in food, pharmaceutical and other mass production environments.
Industrial Uses For Aluminum Foil 7 Micron
Beyond flexible packaging, ultra-thin and formable 7 micron aluminum foil also enables innovative solutions in other industries due to its unique combination of properties. Here are some examples:
Electrical component insulation - Very thin gauges provide compact solutions while repelling moisture.
Lamination substrates - Used as a carrier or transfer layer during the production of multilayer flexible printed circuits.
Thermal management - Excellent heat dissipater for electronics, LED lighting and other applications.
Barrier laminates - Combined with plastics, paper or film to construct high-barrier packaging for food, personal/home care and more.
Medical device packaging - Sterile foils and lidding materials protect medical instruments, implants and pharmaceutical products.
Graphic arts - As an economical print substrate or overlay protective layer for labels, posters and promotional materials.
Decorative foiling - Adds eye-catching metallic surfaces and special effects to various substrate materials.
Industrial barrier packaging - Heavy duty foil provides durable protection for industrial/machinery components or hazardous materials.
The formability and barrier properties of 7 micron alloy 1235 allow it to be thermoformed, extruded, printed, laminated or otherwise converted into a wide array of finished parts, components and applications beyond food packaging. Consistency in gauge and width supports high-volume manufacturing across multiple industries.
Wholesale Requirements for Aluminum Foil Roll Specification
To support the needs of volume flexible packaging producers and other industrial converters, aluminum rolling mills offer customized wholesale programs for the 7 micron x 1220mm aluminum foil specification. Here are some key sourcing considerations:
Minimum order quantities - Typically amounting to multiple metric tons to qualify for favorable pricing based on roll weights.
Packaging & handling - Standard practice involves wrapping foil rolls individually in plastic before stacking on wooden pallets secured with strapping.
Pricing models - Based on current LME aluminum prices, quantity ordered and market supply/demand factors. Long term supply agreements offer the most competitive unit pricing.
Logistics - Delivery primarily by truck, arranged FOB (free on board) from mill sites. International supplier sourcing may involve ocean containerized freight as well.
Technical support - Application engineering assistance provided through in-person visits and digital/phone liaising as needed to address manufacturability or quality issues.
Quality assurance - Certification documents like material COAs, ISO quality management certifications help vet suppliers. Approval sampling may be required for new partners.
Establishing consistent long term supply through pre-negotiated pricing models is preferable to the volatility of spot market purchase orders. Partnering directly with aluminum foil mills allows flexible packaging manufacturers to leverage wholesale bulk aluminum supply chain efficiencies. Having an approved domestic or overseas supplier streamlines procurement of the customized 7 micron x 1220mm aluminum foil roll specification for high-volume production.
In conclusion, the customized 7 micron aluminum foil alloy 1235 width 1220 has become an in-demand specification for the packaging converting industry. Its optimal gauge and width support higher line speeds suited for large-scale flexible food, medical and various other packaging applications. Sourcing pre-slit foil rolls from aluminum mills as opposed to cut sheet or hand-slit materials eliminates inconsistencies while promoting lean manufacturing. With strengths like downgauging possibilities, barrier properties and recyclability, 7 micron foil rolls fulfill key technical requirements in a cost-effective solution. Establishing approved supplier partnerships ensures volume buyers have reliable access to this strategically important roll stock specification.
