Small Custom Printed Food Packaging Bags Self Adhesive Seal
Moisture Proof | | | Speciallity | | Packaging is a series of activities that design and produce
containers or bandages. Packaging as the national economy service
industry, with Chinese socialist construction development,
especially since the reform and opening up, under the socialist
market economy system, the rapid development of packaging industry,
is in the form of a paper, plastic, metal, glass, printing,
machinery as the main form, with modern technology and equipment. A
modern industrial system is complete. | | | | Brief Introduction | Custom Printed Packaging
Now a day, the Custom Printed Packaging is very popular all over
the world,it's use colorful print technology on the suraface of the
packing materials, In the same pages with different color version
printing, color picture effect will reach text, picture, etc. the
plate, ink, pressure and other processes, so that the ink
transferred to the surface of paper, textiles, leather and other
materials, bulk copy the content of technology. Now color printing
generally uses flat printing.
Color printing is a direct or indirect way to make images or text
originals as a printing plate, coated with ink on the printing ink,
the ink is transferred to the paper or other substrates by
pressure, and a large number of rapid replication of an industrial
engineering.
Now color printing generally uses flat printing.
Lithographic printing is sometimes called chemical printing, which
means that the printed image is in the same plane as the printing
plate. It is based on "water immiscible" principle of printing.
This type of printing is done by mechanical or manual means on the
stone or metal surface, and then the surface of the chemical
treatment, so that the image part of the ink, while the other blank
part is not ink. When printing, only the ink image part is
transferred to the paper to form the imprinting. Photographic
printing, photocopying and printing are lithographic printing. | | | | Data Sheet | | Optional Materials: | AL | | Melting Point : | 660℃ | | Working Temperature : | -180~240℃ | | Material Density : | 2.7g/cm³ | | Common Size : | 6"x10" #0 | | Sample Color : | Maroon | | Basic Material : | Aluminum Foil | | Protruding Characteristics : | Moisture Proof | | Typical Application Industry : | Apparel | | Shape Style : | Hand Length Handle | | Classification: | Custom Printed Packaging Bags | | | | | Materials introduction | | Aluminum is a silvery white light metal. Ductility. The products
are usually columnar, rod, flake, foil, powder, ribbon and
filiform. A layer of oxide film to prevent metal corrosion can be
formed in humid air. The acid treated aluminum powder heated in the
air can burn violently and emit a dazzling white flame. Soluble in
dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium
hydroxide and potassium hydroxide solution, insoluble in water, but
can react with hot water slowly to produce aluminum hydroxide, the
relative density of 2.70, elastic modulus 70Gpa, Poisson's ratio
0.33. Melting point 660. Boiling point 2327. It is widely used for
its light, good conductivity and thermal conductivity, high
reflectivity and oxidation resistance. Do the daily dish aluminum
is usually called "steel" or "steel". The thermal expansion
coefficient of Al at (25) Shi Wen is 0.0000236mm/ C or 23.6ppm*k-1. |
