Vogelnest 8011 aluminum foil roll 250mm 8 mic is a thin, weich, fully annealed food-grade foil web. It is mainly used in flexible packaging, Laminierung, lidding and food wrapping. es ist 250 mm wide and 8 Mikrometer (8μm) thin—about a quarter of a household wrap—and is supplied to packaging converters, snack sachet makers, chocolate wrappers, dairy wrapping and lidding lines. Vogelnest 8011 O alloy thus gives the thin foil enough strength and formability without becoming brittle.
In der Praxis, thin foil rolls are the backbone of food packaging. They are laminated to plastic films or paper, printed, and heat-sealed into pouches, sachets and wraps. This guide covers what the roll is, why 8 micron and 250 mm, the alloy and specs, how it is made, Anwendungen, Leistung, Lebensmittelkontakt, QC, pricing and ordering.
Im Kern, the product is a coil of aluminum foil. es ist 250 millimeters wide, 8 Mikrometer dick, and wound on a paperboard or plastic core. In other words, it is a converter roll—not a retail kitchen roll. It is then laminated, printed, slit or heat-sealed by a packaging converter. Vogelnest 8011 alloy in O (fully annealed) temper is soft, ductile and food-contact safe.
Specified fully, the roll reads: Legierung 8011, temper O, gauge 8μm, Breite 250 mm, wound on a 76 mm or 152 mm ID core, with a set length or outer diameter. The converter runs it on packaging, printing or laminating lines. 250 mm is a common web width because it suits pouch and sachet lines without the waste of a jumbo roll.
The base material is 8011 O alloy foil; slightly thicker food-container foil is 8011 Ö 0.014 mm food container foil.
In der Praxis, eight microns sits in the thin-foil range. By comparison, it is thick enough to be pinhole-free for most packaging uses yet thin enough to be economical and flexible. Zum Beispiel, thicker foil (20μm plus) is used where stiffness or deep forming is needed. By contrast, 8μm is used where the foil is a barrier layer inside a laminate, not a structural wrap. The barrier value of aluminum is reached even at very thin gauges, so thin foil is preferred for lamination.
To start, 250 mm is a converter-friendly web width. For context, it suits vertical and horizontal form-fill-seal machines, pouch lines and sachet machines. It avoids the cost and trim of a jumbo roll. EIN 250 mm roll makes two or three typical snack sachets across the web, so there is little edge trim. It also fits laminating and printing machines.
In der Praxis, widths are slit to the customer’s line. 250 mm is generally common for small-to-medium runs. By contrast, 300–600 mm widths serve wider pouches and lidding. Ähnlich, 100–200 mm rolls serve sachets and blister webs. Vogelnest 250 mm choice balances line throughput, trim waste and handling—it is a standard packaging width, not a kitchen width.
Put simply, 8011 O is the standard thin packaging foil. Notably, its small iron content adds strength and pinhole resistance over pure foil. Full annealing also keeps it soft. For an 8μm lamination web, that balance matters. Pure 1235 is smoother but more delicate, and harder alloys do not conform. 8011 O thus runs on packaging lines without cracking and seals cleanly.
For composite and lidding, converters also use 1235 composite flexible packaging foil; for heavier structural foil, 3003 anti-rust aluminum foil is specified.
In der Praxis, the roll is defined by gauge, Breite, core, length/OD and surface. At 8μm, pinhole count and gauge consistency are the critical specs. A pinhole leaks the barrier and ruins the pack. Converters specify maximum pinholes per square meter and gauge tolerance. The surface—matte or bright—is chosen by the lamination and printing process.
In production, thin foil starts from thicker cold-rolled aluminum coil. Along the way, it is repeatedly cold-reduced on rolling mills down to around 8 Mikrometer. It is next annealed in a furnace to soften it back to O temper. Finally it is slit to 250 mm and rewound onto cores. Typisch, two thinner layers are rolled together to reach 6–8 microns. After annealing, the foil is separated (split), giving one bright and one matte side.
In der Praxis, reaching 8 microns without pinholes is a precision process. Rolling oil, roll finish, tension and annealing atmosphere all control surface quality and pinhole count. The finished web is then inspected for pinholes, gauge and edge before slitting. A clean, uniform 8μm roll thus runs reliably on packaging lines. Umgekehrt, a pinholed or uneven roll causes leaks and web breaks.
On the slitting line, width is set. Zuerst, a wide jumbo foil coil is run through rotary shear knives. These then cut it into 250 mm strips, each rewound on its own core. Edge quality matters: a burred or ragged edge catches on the laminator. The slitting line also sets tension so the roll winds evenly without telescoping. Thus, a well-slit 250 mm roll runs quietly; a poorly slit one jams.
Across all these uses, the foil is the barrier layer. Zuerst, plastic films provide strength and sealability. Nächste, paper provides print and stiffness. Endlich, the aluminum provides the oxygen, light and moisture barrier that keeps snacks fresh. At 8μm the foil is thin enough to laminate and seal cleanly. Trotzdem, it is thick enough to stay pinhole-free for most shelf-stable foods.
On the dairy side, wrapping is a separate use case. Butter and cheese are often wrapped directly, not laminated. It also must dead-fold and block air and light in the fridge. A slightly stiffer 12–15μm foil is common. That said, 8μm is used where the wrap is backed by paper or film. Again, Die 250 mm width suits small butter and portion packs.
In der Praxis, the gauge is matched to the job. For a lamination where plastic supports the foil, 8μm is enough and cheapest. Buyers sometimes over-specify thicker foil for lamination. jedoch, it adds cost and stiffness without barrier benefit, since even 6μm aluminum is a complete barrier.
At the performance level, aluminum is a near-perfect barrier: it blocks 100% of light, Sauerstoff und Feuchtigkeit. That is why even thin foil is used for long-shelf-life snacks and dried goods. In der Tat, no plastic film matches it. Vogelnest 8011 O temper gives softness and dead-fold, so the web wraps around products and seals. Thin foil also heat-seals well when laminated to a heat-seal film.
That said, the limits are mechanical. Bare 8μm foil punctures easily, which is why it is laminated rather than used alone. jedoch, it is not for oven use or formed trays. Rather, it is a cold packaging web. For packaging converters, the key properties are pinhole count, tensile strength on the line, flatness and sealability—not raw stiffness.
On top of barrier, dead-fold is a valued property. Soft O-temper 8μm foil holds a crease. So a wrapped chocolate bar stays wrapped and a lidding foil folds back cleanly. Thicker or half-hard foil springs back and unwraps. This softness is why 8011 O is preferred for wrapping and lamination. It behaves like a conformable barrier, not a stiff sheet.
On food contact, 8011 O thin foil is an approved food-contact material under FDA and LFGB frameworks. The converter controls those layers. Bezogen auf 0,002 mm dicke Aluminiumfolie, the foil itself is inert and safe against snacks, Schokolade, dairy and dried foods. Exporters should provide food-contact declarations and migration test reports for the destination market.
That said, as with all aluminum, long contact with highly acidic or salty foods is not the use case. Here, the 8μm packaging is for sealed, shelf-stable snacks and dry goods, not long-term storage of tomato sauce. The foil is also microwave-unsafe bare. Laminated packaging is then heated only as directed. Food-contact documentation is part of the sale.
On the surface, thin foil has a matte side and a bright side. This is a natural result of rolling two layers together and splitting them after annealing. Infolge, the bright side is smooth and reflective. The matte side is softer and better for lamination adhesion and printing. Converters specify which side faces the lamination adhesive or the food.
Beyond look, surface cleanliness matters. Thin foil must be free of rolling oil, stains and pinholes for food packaging. A clean surface also ensures lamination bond strength and print quality. The mill then controls this through cleaning and controlled annealing. The converter in turn rejects oily or stained rolls that delaminate or print poorly.
For printing, the bright side accepts ink well and gives a reflective premium look. The matte side offers a softer, less reflective finish. Converters choose the printed side based on brand design. The two sides differ, so winding orientation must be specified. A roll wound matte-out instead of bright-out causes re-threading and rejects on the press.
Surface roughness is measured for premium print and lamination. A bright side with low roughness gives high reflectivity. A matte side with controlled roughness bonds better to adhesive. Converters running high-speed printing or deep laminating specify roughness along with gauge. A surface that is too smooth delaminates. One that is too rough loses print definition. The mill controls this through roll finish and annealing.
On the mill side, the converter’s QC focuses on pinholes, gauge and winding. The mill’s QC, dagegen, focuses on alloy, temper and surface. Incoming, converters run the web on a trial laminator. If it delaminates, prints poorly, or breaks under tension, the roll is rejected. Pinholes are the hidden killer—an otherwise good roll thus leaks oxygen and spoils the pack.
On the incoming side, a simple audit catches most risks. Zuerst, weigh a roll against declared gauge. Then run a length through the laminator to check delamination. Also inspect the surface for oil or stains, and count pinholes on a sample. A consistent supplier that passes these on every shipment is worth more than the cheapest per-kilo roll. Winding tension also matters. An overly tight roll telescopes or crushes the core on the line.
Pinhole testing is done with a light table. The web is illuminated and holes counted per square meter. For shelf-stable products, a low pinhole count is essential because each pinhole is a path for oxygen. The mill guarantees a maximum count, and the converter verifies on receipt. This is the single most important spec for thin foil—more than gauge, more than width, more than surface.
In der Praxis, 250 mm is a standard, but converters order slit widths matched to their line. Widths from 100 zu 600 mm are common. Roll length or outer diameter is then set by the core and line capacity. Kern-ID (76 mm or 152 mm) must also match the converting machine. Custom gauge (6–20μm) and surface are likewise available. Slitting is low-tooling, so width is flexible. Gauge and alloy are instead set at the mill.
Beyond standard widths, private-label and packaging brands specify the full roll: Legierung, Temperament, Messgerät, Breite, core, Länge, surface and packaging. Standard 250 mm 8μm rolls are fastest. Custom gauges and widths carry a small setup. Buyers should sample a roll on their actual laminator before volume, because line speed and tension vary.
In transit, export packing protects thin foil from moisture and edge damage. Because 8μm foil is thin, water marks or crushed edges cause rejects. Good export packing is part of the product, not an afterthought.
On arrival, the converter should inspect each roll before loading it. Check the outer diameter against the spec, confirm core ID, and run a short length off the roll to confirm the matte/bright orientation. Also look for edge crush or moisture marks.
The price sits on the aluminum base (LME-linked) plus cold rolling, annealing and slitting. Thinner gauge still costs more per kg but covers more area per kg. MOQ is typically a pallet per size. Custom gauges and slit widths then run to a tonne or container. The web is light and rolls are dense, so freight is reasonable. Thin foil thus covers much area per kilogram.
Beyond headline price, total cost includes yield. A pinholed or uneven roll causes lamination rejects that far exceed the per-kg saving. Buyers should ask for a delivered cost per thousand square meters of usable, pinhole-free web. They should not look at just the foil price per kg. Consistent gauge and low pinholes are worth more than the cheapest roll.
On top of that, aluminum price tracks the LME, so quotations carry a short validity. Thin foil rolls are light but dense, so container loading is efficient. A 20-foot container carries many rolls. Buyers should ask for a delivered cost per thousand square meters in their chosen core and width. Two suppliers with similar foil price can differ on slitting yield, packing density and freight.
