Charming Metallic Foil Mailers , Lake Blue Padded Envelopes 145x210mm #C For Lipstick
| Brief Introduction | |
| Metallic bubble mailers Product description: Metallic bubble mailers is made of low density polyethylene (LDPE). The features of low cost, large volume, good waterproof performance. Usually we receive the courier package, the package outside the black or gray bag is the courier bag. LDPE film flexibility, are not easy to be torn, comparison of bright color printing, many logistics companies in order to achieve the effect of publicity will custom printed graphic courier bags. Express bag also has anti theft special self-adhesive tape, the self-adhesive posts with a one-time, non recovery characteristics and prevent the parcel before delivery to the recipient is opened without authorization, using a very simple and convenient. Product principle: Metallic bubble mailers has self-adhesive tape, using a special glue, as long as mouth closed, then open it will damage opening or a mark was opened, which is prevention in parcel transport process is stolen. At the same time the bag is closed, the sealing property is good, effectively waterproof, sunscreen. Structure: The 1 layer is made of pure low density polyethylene film. Making method: Metallic bubble mailers use high quality low density polyethylene material by blow molding equipment to produce Poly film, then composite with self-adhesive tapes. Finally, making equipment produce finished bag. Production process: The blow molding process, composite process, bag making process Product parameters: Thickness of 11 wire size can be customized characteristic: 1 light weight, large volume. 2 strong flexibility, not easy to be torn 3 self adhesive tape, security and security open 4 waterproof, sunscreen Use: Express bag, mailing bag, Bao Guodai | |

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.
