In the field of pharmaceutical packaging, aluminum barrier foil for pharmaceuticals plays a vital role. It can effectively protect drugs and extend their shelf life. There are many types of pharmaceutical aluminum foil, among which PTP aluminum foil, cold-formed aluminum foil and tropical aluminum foil are more common.
PTP blister foil, also known as heat-sealable pharmaceutical aluminum foil, is one of the most widely used pharmaceutical aluminum foils. One side of it is coated with a heat-sealable material. Under the action of heat and pressure, it can be tightly bonded with hard sheets such as polyvinyl chloride (PVC) and polyvinylidene chloride (PVdC), thereby forming a blister package and sealing the medicine in it.
Features
Good barrier properties: The aluminum foil itself has excellent barrier properties, which can effectively block oxygen, water vapor and light, prevent the medicine from getting damp, oxidized and deteriorating, and provide a stable storage environment for the medicine.
Easy to heat seal: The coated heat-seal layer enables PTP aluminum foil to be quickly and firmly heat-sealed with the pharmaceutical hard sheet to form a well-sealed blister, which is simple to operate and has high production efficiency.
Clear identification: The surface of PTP aluminum foil is suitable for printing, and important information such as the name of the drug, specifications, production date, expiration date, and method of administration can be clearly printed, which is convenient for patients and medical staff to identify and use.
Easy to use: The blister packaging design allows patients to take medicines one by one according to the dosage, avoiding secondary contamination of the medicines. It is also easy to carry and suitable for daily use.
Specifications
The thickness of PTP aluminum foil is usually between 0.02mm and 0.03mm, and the width varies according to different production requirements and packaging equipment. Common specifications include 100mm-1000mm.
Price
The price of PTP aluminum foil is affected by factors such as raw material cost, market supply and demand, production process and quality requirements. Generally speaking, the price of ordinary quality PTP aluminum foil is about 3000 to 4000USD per ton. If there are higher requirements for the purity, coating quality, printing effect, etc. of the aluminum foil, the price will increase accordingly.
Cold forming aluminium foil is a kind of medicinal aluminum foil that can be stamped and formed at room temperature without heating. Its unique forming method makes it occupy an important position in pharmaceutical packaging.
Features
High strength and good formability: Cold-formed aluminum foil usually uses specific alloy such as 8021-O aluminum foil, 8079-O aluminum foil, etc., with high strength and good cupping value. It can be stamped into various shapes at room temperature, and the formed blisters have good stiffness and are not easy to deform.
High barrier performance: Cold-formed aluminum foil has excellent barrier properties against gas, water vapor and light. Compared with some other types of pharmaceutical packaging materials, it can provide better protection for drugs, especially suitable for drug packaging that is sensitive to environmental factors.
Strong puncture resistance: Aluminum foil itself has a certain hardness and toughness, so that the packaging made of cold-formed aluminum foil can effectively resist external puncture and extrusion during transportation and storage, reducing the risk of damage to drugs.
Customizability: Cold-formed aluminum foil can be customized in a variety of ways according to the shape, size and packaging design requirements of the medicine to meet the personalized packaging needs of different medicines.
Specifications
The commonly used thickness range of cold-formed aluminum foil is 0.025mm - 0.08mm. Its width specification is similar to that of PTP aluminum foil and can be customized according to actual production needs, generally between 100mm - 1000mm.
Price
Due to the high requirements for materials and production processes, the price of cold-formed aluminum foil is relatively more expensive than PTP aluminum foil. The market price is roughly around 4000-6000 USD per ton, and the specific price will also fluctuate due to different alloy composition, quality grade and purchase volume.
Tropical aluminum foil, also known as tropical medicinal composite aluminum foil, is mainly used for drug packaging with high requirements for moisture and heat resistance. It is widely used in tropical and high temperature and high humidity areas.
Features
Super strong moisture resistance: Tropical aluminum foil usually adopts a multi-layer composite structure, in which the aluminum foil layer is composited with materials with excellent moisture resistance, which can effectively block the intrusion of water vapor and ensure that the drugs remain dry in high temperature and high humidity environments.
Good thermal insulation performance: It can block external heat transfer to a certain extent, reduce the impact of temperature changes on drug quality, and maintain the relative stability of the drug storage environment.
Reliable barrier properties: In addition to moisture and heat insulation, tropical aluminum foil also has a good barrier effect on oxygen and light, and fully protects drugs from interference from various adverse environmental factors.
Corrosion resistance: For special environments such as corrosive gases that may exist in tropical areas, tropical aluminum foil has been specially treated and has certain corrosion resistance, which extends the service life of the packaging.
Specifications
The thickness of tropical aluminum foil is generally between 0.03mm and 0.06mm, and the width specifications are also quite diverse, with common widths of 100mm to 800mm to meet the needs of different packaging production lines.
Price
Due to its special performance requirements and complex production process, the price of tropical aluminum foil is relatively high, about 5,000 to 8,000 USD per ton. The price will vary depending on the number of composite layers, material quality and market conditions.
