Most of the drugs are easy to oxidize, absorb moisture, decompose and deteriorate, and the aluminum foil packaging has good shading and compactness, can protect the inner packaging medicine from oxidation, moisture absorption and deterioration, and has good calendering property and is easy to produce and easy to disassemble. The aluminum foil is light in weight, has metallic luster, good light-shielding property, high reflection ability to heat and light, good insulation and strong protection. It is non-breathable and water vapor, free from bacteria, mold and insects; it has good shape stability and is not affected by temperature changes. Most of the medicinal aluminum foils are in the form of aluminum-plastic composite film to achieve better moisture resistance and flexibility, and also consider the hygienic properties of the drug.
The aluminum foil for medical packaging is mainly used for packaging of liquid and injection, and PTP aluminum foil for easy opening of bottle cap and pharmaceutical packaging. In particular, PTP aluminum foil has the advantages of moisture-proof, safe and hygienic, and easy to carry, and aluminum foil is widely used in packaging fields such as food and medicine.
Say a few aluminum foil features:
(1) The surface of the aluminum foil is clean and hygienic, and its surface does not grow any bacteria or microorganisms.
(2) Aluminum foil is a non-toxic packaging material that can be in direct contact with food without any health hazards.
(3) Aluminum foil is an odorless and odorless packaging material that does not impart any odor to the packaged food.
(4) If the aluminum foil itself is not volatile, it and the packaged food will never dry or shrink.
(5) There is no oil penetration of the aluminum foil at high temperatures or at low temperatures.
(6) Aluminum foil is an opaque packaging material that can be used to package foods that are afraid of the sun, such as butter.
(7) Aluminum foil has good plasticity, so it can be used to package products of various shapes.
(8) Aluminum foil has high hardness and large tension, but its tear strength is small, so it is easy to tear, that is, the anti-support is not resistant to tearing.
(9) When aluminum foil is in contact with other heavy metals or heavy metals, chemistry may occur, so it is necessary to store aluminum foil to separate it from other metals.
