Cold rolled steel coils are often used in the steel industry and are different from hot rolled coils. It refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole roll with a winder. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but generate more internal stress, and are often annealed after cold-rolling.

(1) Aluminum foil surface is clean, sanitary, no bacteria or micro-organisms can not grow on its surface.
(2) aluminum foil is a non-toxic packaging material, it can directly contact with food without any harm to human health.
(3) aluminum foil is a kind of tasteless odorless packaging material, will not make the packaging of food have any peculiar smell.
(4) aluminum foil itself is not volatile, it itself and packaged food will never dry or shrink.
(5) at high temperature or low temperature, aluminum foil will not have the phenomenon of oil permeability.
(6) aluminum foil is a kind of opaque packaging material, so it is a kind of good packing material for the products of sunlight irradiation.
(7) aluminum foil has good plasticity, so it can be used to pack all kinds of products. Can also cause any shape containers.

Metal extrusion is the manufacturing process of choice when producing high volumes of material with a constant cross-section. With the extrusion process, metal material is forced through the shaped opening of a die using high pressure, resulting in an extruded profile. These profiles range from simple shapes like round or rectangular tubes, U- or H-channels, or more complex profiles with multiple internal hollows and external features, such as 80/20 and T-slot framing bar. Extrusion is also standard for wall and window trim as a cosmetic and structural framing component. The raw material typically comes in billet form, which is heated and placed into part of the extrusion press called the container. A die stack sits on the other end of the container, forming the opening, which shapes the material to the desired shape using direct or indirect extrusion methods. The extrusion is then quenched, straightened, sawed to the specified length, and inspected for dimensional consistency and accuracy. Extruded products can easily be post-processed to add features outside the channeled profile.
