WHY METAL? Metal is one of the world’s most abundant raw materials, superior content protection and boast a very low environmental impact.

Types of Metal Liners:
C-Enamel liner works with low acidic foods “Think C is for Corn”. For prolonged stored foods with low acidity, but have the ability to discolor a raw metal can surface.
White Enamel liner works with higher acidic foods “Think Red”, like beets, berries, tomatoes, etc.
Epoxy liner is suitable for most latex and water based solvents and increased chemical compatibility.
Laquer liner is FDA approved and for more acidic foods and aggressive solvents.

FAQ's About Metal:
Heated? Tinplate can be heated up 450°F (230°C). Carbon and Stainless Steel can be heated up to 2600°F.
Rust? Much of our metal is treated with a rust inhibitor, but not rust preventer. Rust is based on moisture and oxygen and however much exposure a container gets to either one of these post manufacturing is what will determine if any, how much rust you will incur. Testing is recommended with your product.

TERMS AT A GLANCE Bead: concave (interior bead ) or convex (exterior bead ) area usually 1/8" wide spanning the circumference of the tin to provide additional strength and stability to the tin body Body: a can without a cover (lid); the base of a container Cover: a can’s lid or closure Curl: area of tin turned in on itself to provide a safe, finished curved edge Dome: a type of cover characterized by a flat horizontal surface (top) that tapers smoothly onto the skirt (vertical surface) Drawn: see seamless End: the area of a tin also known as the bottom. Coffee-style hermetic tins generally have two ends. Ends can be attached by seaming them on or crimping Full friction: a plug-style metal cap fits snugly to the interior of the can Hem: similar to a curl, an area of tin turned in on itself to provide a safe, finished flattened edge Interior Friction: Cover/closure option in which a pliable ring fits to the interior of a tin allowing for a straight-sided slender profile can

Lock-seam: side walls meet and attach by hooking onto one another to form a tin body Multiple friction: a plug closure fits into a “well” of a seamed-on ring. The plug is pressed into the ring and the two surfaces (the outside and inside edge) come into contact with the ring, creating multiple sealing surfaces on the plug/ring combination Seamless: a tin that is constructed from a single piece of tin drawn to form the body of the can Single friction: a plug-style metal cap fits snugly into a seamed on ring. The outside edge of the plug presses against the interior edge of the ring, creating one sealing surface Slip cover: cover/closure style in which the cover’s skirt (vertical surface) slips over and to the outside of the can body Stepped cover: type of slip cover in which a “step” is created between the horizontal surface and vertical surface of the cover so that stacking tins is possible with less likelihood of toppling over Welded Seam: seam type in which side walls attach to one another through the use of heat to form a tin body White Coat: entire surface of the metal is coated with white before applying other printing ink colors Thanks to Allstate Can Corporation for this great can anatomy information.
