13 Micron Aluminum Foil Roll 30cm Width Food Contact

13 Micron aluminum foil is widely used as a packaging material for direct food contact due to its lightweight, malleability, barrier properties and recyclability. Thin 13 micron aluminum foil rolls in sheet widths suitable for foodservice and consumer packaging applications are in high demand. One such product specification is a 30cm wide roll of 13 micron aluminum foil for direct contact with food items. This article explores the characteristics and applications of 13 micron x 30cm aluminum foil rolls designed for safe food preservation and storage.

What is 13 Micron Large tin rolls used in the kitchen?

Large tin rolls used in the kitchen is measured in thickness using the metric unit of measurement known as a micron. One micron equals one millionth of a meter, or 0.001mm. A 13 micron thickness Aluminum foils 8001 therefore measures 0.013mm thick. This extremely thin yet robust grade is well-suited for direct contact with foods due to its lightweight and moldable nature.

In terms of its material properties, 13 micron Aluminum foils 8011 typically has:

Purity of 99% aluminum composition or higher as the main metal constituent.

Density of approximately 2.7g/cm3, contributing to an incredibly low material footprint.

High strength-to-weight ratio even at ultra-thin thicknesses.

Excellent corrosion resistance from a thin self-healing aluminum oxide barrier layer.

Barrier properties prevent gases, moisture, microbes from permeating through.

100% recyclable at end-of-life through aluminum recycling streams.

Processing 13 Micron Aluminum Foil Rolls

Raw aluminum ingots are continuously cast into thin strips or foils through hot and cold rolling processes. Foils are frequently annealed to soften the metal and impart smoothness. 13 micron aluminum foil strip is produced through the following manufacturing steps:

Melting and casting - High purity aluminum alloy melted and cast into strips or thin slabs.

Hot rolling - Heated aluminum work-hardens into thinner gauges through multiple rolling stands.

Cold rolling - Additional smooth reduction at ambient temps to final 13 micron thickness specification.

Coiling - Long foil ribbons are coiled into master log rolls weighing many tons each.

Slitting - Master coils slit into narrower "jumbo" or "conversion" rolls for secondary processors.

Inspection and testing - Foil undergoes inspections for thickness variation, imperfections.

Packaging and preparation for shipment in widths common for foodservice use.

The ultra-thin 13 micron gauge holds tight dimensional tolerances through repeat rolling passes and quality monitoring systems. Controlled processing yields a very consistent final product specification.

Food Contact Applications of 13 Micron Aluminum Foil Rolls

Common applications exploiting the characteristics of 13 micron x 30cm aluminum foil rolls for direct food contact include:

Foodservice foil wraps - Over wrapping meats, cheeses, prepared salads, bakery items at delis and takeaways.

Retail produce bags - Transparent bags for fruits, vegetables provide respiratory transmission barrier.

Sandwich/snack wraps - Aluminum laminated to paper or plastic films for food to go convenience.

Ice cream/frozen food wraps - Fragile frozen items protected through retail freezer shelves and home use.

Baked goods wrappings - Aluminum sheets to wrap or box fragile pastries, muffins, cookies, and prevent crushing.

Candy/snack wraps - Individually wrapping potato chips, nuts, trail mixes, confectionery items on production lines.

Catering and institutional use - Portioning and covering food dishes, pans for events, hospitals, nursing homes etc.

Home food storage - Stretching across bowls or repurposing containers preserves leftovers in the fridge.
