PTP aluminum foil pharmaceutical structure
Aluminum foil pharmaceutical includes protective layer (OP), outer printing layer, aluminum foil substrate (AL), inner printing layer, adhesive (VC), etc. At present, bubble cover packaging is becoming more and more common in health food and drug tablet and capsule packaging, and aluminum-plastic bubble cover, also known as water bubble eye packaging, is abbreviated as PTP. The aluminum foil used in bubble cover packaging is the sealing material on the medicinal plastic polyvinyl chloride hard sheet, so it is also called cover material. Almost all products in modern packaging that require opaque or high barrier composite materials use aluminum foil as a barrier layer, because aluminum foil has a highly dense metal crystal structure and can completely block any gas, so it is widely used. It is expected that packaging materials used for drug bubble covers will account for about 60% to 70% of the tablet and capsule packaging of future drugs, and is one of the best drug packaging materials with the best development prospects. Executable standards: national standards, American standards, European standards, Russian standards, Japanese standards, etc.
Advantages of pharmaceutical PTP aluminum foil
High-precision printing, rich colors, and clear patterns. The plain foil can be printed online by automatic drug bubble cover packaging machine.
PTP aluminum foil has good oxygen resistance, moisture resistance, and can avoid light and maintain quality by sealing with molding material.
The protective layer of PTP aluminum foil has excellent high-temperature resistance, and the adhesive layer has good heat sealing performance and good sealing performance.
Using aluminum foil as the base material, it is easy to push or puncture, convenient for consumers to take, the packaging bubble cover board is easy to carry, easy to transport and store, and prevents pollution.
It is suitable for high-speed automation production, and manufacturers can provide products of various widths according to the user's packaging machine model.
Drug PTP aluminum foil is non-toxic, tasteless, lightweight, and has excellent light-shielding performance, high moisture resistance, and barrier properties
The base material of PTP aluminum foil pharmaceutical can be divided into hard aluminum foil and soft aluminum foil. The former is mostly used for vacuum packaging of tablets and capsules, and the latter is generally used for outer packaging of powder particles and powder composite soft packaging. Drug PTP foil is generally made of aluminum alloy, which has excellent mechanical and pinhole properties, and the roughness and glossiness are better than pure aluminum foil, which is beneficial to printing and decoration. With the development of the pharmaceutical industry, the quality requirements for pharmaceutical aluminum foil are becoming higher and higher. For example, as the types of printing colors increase, the surface quality requirements of pharmaceutical aluminum foil are also getting higher and higher. With the increase of the speed of coating and coloring equipment, higher requirements are put forward for the mechanical properties of pharmaceutical packaging aluminum foil.
Aluminum foil produced by PTP is non-toxic and tasteless, and does not cause any harm to the human body. It also has good conductivity and sunscreen performance. Aluminum foil used for drug packaging also has high gas barrier, moisture resistance, and flavor protection properties. No matter what kind of metalized film or coated special film, it cannot completely replace aluminum foil. PTP aluminum foil not only has the above advantages, but also has the characteristics of lightweight, certain strength, and good printing performance. Using aluminum foil as a drug bubble cover packaging, it is very convenient for patients to take medication, so pharmaceutical companies will choose aluminum foil as a pharma packaging material.
