Metal container from the stuffing to the temporary storage
function, the evolution to today's food cans, beverage containers, transport
and packaging, from production to allotment and consumption from a flow of
container contents to become a means of long-term protection can be said that
the metal to the human everyday life is a big change and progress.
Aluminium packaging materials, esp. metal protect film application
in fast development, variety, is generally used in industrial products,
packaging, transportation, packaging and sales packaging, packaging materials,
mainly because aluminium has the following characteristics:
1. Aluminium packaging materials, outstanding mechanical
properties, high strength, aluminium containers can be prepared so thin, high
strength, unbreakable containers. This makes packaging products with consistent
security protection, and easy to store, carry, transport, handling and use.
2. The processing of aluminium packaging material
performance, processing technology development, continuous, automated
production. Aluminium packaging material with good ductility and strength, can
be rolled into a variety of thickness of the plate, foil, plates can be stamping,
rolling, stretching, welded containers of different shapes and sizes; foil with
plastic, low for complex, which in a variety of forms metal can give full play
to excellent, comprehensive protection performance.
3. Aluminium packaging material has an extremely good
overall protection performance. An extremely low water vapour conduction rate
of aluminium, completely thick, and can effectively avoid the harmful effects
of ultraviolet light. The gas-barrier, moisture, shade and fragrance preservation
is much higher than the plastic, paper, and other types of packaging materials.
Therefore, gold aluminium apparatus for a longer time to maintain product
quality and long shelf life, which are particularly important for food
packaging.
4. Aluminium packaging material has a separate metallic shine,
but also easy-to-print decoration, it will give the product the emergence of
Huagui Fu Li, good-looking and marketable. In addition, the foil material is a
very good mark.
5. Aluminium has frequent respectability of packaging
materials, from the environmental protection viewpoint, is the green ideal
packaging material.
