Why is aluminum foil in high demand in the pharmaceutical industry? – Observational Research
The use of high-quality medicine requires special care to ensure its effectiveness. As a result, their packaging must be safe and protected from moisture, oxygen, and the environment. The pharmaceutical industry uses blister packs for their medicines. “Blister” (push-through blister) is a molded plastic with cavities inside for each medicine. Aluminum foil is use to create a push-through closure called lid film or blister film. As a result, the tablets and capsules are well protect and hygienically protect. Bulk blister packs are portable, compact, and easy to handle. The aluminum foil protects tablets from external factors that could reduce their effectiveness until they are consumed. To ensure that in the future, the products meet all the requirements such as quality, reliability, and hygiene, they are still being improve. Apply the same medical-hygienic standards use in the pharmaceutical industry for the production of tablets and other related products in the production of coated or printed blister films.
Heat-sealing lacquer for sealing blisters with blister films
For effective protection of tablets, the plastic push-through blister has to seal with an Aluminum cover. Heat seal lacquer or any other suitable sealing agent is appli to the aluminum foil for this purpose. Aluminum foil is app after the tablets are place in the individual cavities of the blister mold. The blister material combines with the heat seal lacquer on the aluminum foil when the right pressure, heat, and time are appl. The tablets are perfectly seal against any environmental influences. A primer is printe on the blister package often along with other markings or the manufacturer’s logo to help the consumer recognize the drug.
Blister cover foil made of aluminum
Hard and soft Aluminum is use for push-through packaging. In the past, only hard aluminum foil was use because it could break easily and release the medicine easily. Soft aluminum foil is considered child-resistant because its high stretching power makes it more difficult to open with just one hand. The effect can be intensified by using a laminate of aluminum and PET or paper.
Cover material made of hard Aluminum
A hard aluminum foil with a thickness of approximately 25 micrometers is preferre by the European pharmaceutical industry. If the drug is to be taken, it can simply push through the aluminum opening. The seal on the outside is usually print. In some cases, there could also be writings on the inside of the heat seal lacquer. A double coat of heat seal primer and heat seal lacquer must apply. The primer’s purpose is to ensure that the heat seal lacquer adheres securely to the aluminum foil and is in line with it. Dye is sometimes add to the primer for marketing purposes. The primer is follow by a heat seal lacquer in such cases. If the medicine is dyed, the heat sealant protects it from the color pigments in the primer. Color pigments are placed between the heat sealant lacquer and the Aluminum Blister Foil Manufacturer in India. The heat seal lacquer, color pigments, and prime must be perfectly matche.
Cover material made of soft Aluminum
It is similar to the use of hard Aluminum foil when using soft Aluminum. To prevent children from accessing tablets, it is use. It is preferable because it is soft and requires a lot of force to open. Children have a hard time opening aluminum foil because of its flexibility and thickness
Composite blister film made of aluminum, paper, and PET
Aluminum and paper composite films and PET are use as cover films in the pharmaceutical industry. The paper is laminate with aluminum foil with a weight of 40-50 g/m2. Paper and foil cover foils can print directly on the outward-facing surface of the paper. The aluminum with paper is use in Europe as children’s protection, whereas in the USA it is use as a peel-off foil that must remove in one piece from the blister pack. The packaging is referre to as peel-off-push-through, in which the composite of PET and paper must first remove before the tablet is force out. The aluminum foil has to be thicker so that the paper can peel off in its entirety.

Trends in pharma-industry
Pharmaceuticals are growing fast with many people being able to afford medicine. As technology develops, companies want diversified products. Due to this, technicians have had to be creative with their products while still maintaining high quality standards.
