Specification and performance of pharmaceutical aluminum foil

Pharmaceutical aluminum foil is used for pharmaceutical packaging aluminum foil, referred to as medicinal foil. Aluminum foil is one of the main packaging trends of medicines nowadays. It is the only metal material in packaging materials. Medical aluminum foil is a kind of medicinal packaging material which has not been replaced so far.
Aluminium foil in flexible food packaging started relatively late in China, accounting for about 25% of the total drug packaging, of which aluminum-plastic blister packaging accounted for 20%. Therefore, the market capacity of pharmaceutical aluminum foil packaging in China still has great room for development.
Specification and performance of pharmaceutical foil
(1) aluminum alloy grades: 1070, 1145, 1235, 8011, 8021, 8079, etc.
(2) state: O, H14, H16, H18, H19, H22, H24, main state H18.
(3) thickness: 0.018-0.5 + 0.002mm. Main thickness: 0.02mm, 0.021mm, 0.022mm, 0.023mm, 0.024mm, 0.025mm, 0.026mm, 0.030mm, etc.
(4) width: 100~1650 + 0.5mm, main width 300~600mm.
(5) the tensile strength of the medicinal foil is 98Kpa and the rupture strength is 90Kpa.
(6) good thermal stability in the range of 130 to 200 c.
(7) pharmaceutical aluminum foil requires a good version without wrinkles and no lotus leaves.
(8) the holes and holes of medicinal foil are strict. The requirement for needle holes of aluminum foil for medicinal and health food is that the pinholes of 0.1 to 0.3mm diameter are not more than 1 /m2.
(9) medical foil requires no bright spots on the dark side, and highlights defects affect aesthetics and printing performance.

(10) The surface is clean and free of grease, aluminium ash, black thread and grease stains, and the wetting tension is greater than 32 dyne.

What is the difference between aluminium foil and sheet

What is the difference between aluminium foil and sheet ? aluminium foil is any thickness of material thinner than .006". Material thinner than .0005" thick, has become more known as converter foil and can be manufactured down to .00015" thick. In contrast, sheet material ranges from .006" up to .080" thick, regardless of the metal type. If you are looking for thickness greater than .080", the product you desire is considered metal aluminum  sheet. When it comes aluminium foils specification: Alloy:8011/1235/1100/1145/3003 Temper: O/H32/H18 Width:200-1300mm Thickness:0.006mm -0.2mm when it comes aluminium sheets specification: Grade: Series: 1050, 1060, 1070, 1100, 1200 and 1235 Series: 3003, 3004, 3005, 3104, 3105 and 3A21 Series: 4045 and 4343 Series: 5005, 5052, 5083, 5086, 5154, 5182, 5251 and 5754 Series: 6061, 6063, 6082 and 6A02 Series: 7005 and 7075 Series: 8006, 8011 and 8079 Continuous casting and hot rolled both available We cr

Application of aluminum plate in different industries

图片
Aluminum plates are widely used in various fields, such as ships, refrigerators, dies, aerospace equipment and so on. Applications of Alloy Aluminum Sheet : Ships The most important feature of shipbuilding is that the material used should have good performance, not easy to wear and corrosion, so alloy aluminum plate is the best choice of materials. Because the alloy aluminium plate is mainly made of aluminium material, it has good performance, is not easy to damage, has a long service life, and can meet the requirements of ship production. Application of Alloy Aluminum Plate: Refrigerator The most important feature of refrigerator production is to have good sealing. Refrigerators need refrigeration and fresh-keeping effect in the process of using, so the material used can meet these two requirements, so alloy aluminum plate is the best choice. Because the sealing performance of alloy aluminium sheet is very good, it can meet the manufacturing conditions of refrigerato

Auminium sheet 5083 H116 VS H321 in marine application

图片
Which of the properties of 5083 H116 and H321 aluminium alloy sheets is better in marine application? It is necessary to know the difference between alloy 5083 aluminum plates H116 and 5083H321 aluminum alloy sheets. According to the contents of CCS Code for Materials and Welding: 1. H116: Aluminum alloy with magnesium content not less than 3.0% after corrosion protection treatment. 2. H321:Magnesium content not less than 3.0% of the aluminium alloy after work hardening and stabilization treatment. Look at the relevant definitions of anti-corrosion treatment and hardening treatment (also refer to the national standard GB): H1* - Hot rolling, strong tension; H2* - Continuous casting and rolling, strong tension and partial toughening; H3* - After internal stress treatment, stable performance; H4* - Painted or coated; H*2-25% hardness treatment, H*4-50% hardness treatment; H*6-75% hardness treatment; H*8-90 hardness treatment. H116: Suitable for 5000 seri
