Läpipainopaperi

Läpipainopaperi, also known as blister paper or pharmaceutical foil, is a packaging material commonly used for medicines and other small, sensitive items. It consists of a plastic or aluminum blister cavity that is sealed with a backing material, typically aluminum foil or a plastic film. This construction protects the contents from moisture, light, and air, thereby extending their shelf life and maintaining their efficacy.

The blister cavity is formed by a process called thermoforming, where plastic film is heated and then molded into the desired shape. This shape is designed to hold a specific number of doses, ensuring accurate and convenient dispensing. The backing material is then heat-sealed to the edges of the blister, creating a tamper-evident seal.

Läpipainopaperi offers several advantages. Its transparency allows consumers to visually inspect the product before purchase, and the individual cavities make it easy to track dosage and prevent accidental overdose. The protective nature of the packaging is crucial for pharmaceuticals, safeguarding them from environmental degradation. Furthermore, the compact and lightweight nature of läpipainopaperi makes it efficient for storage and transportation. It is widely used in the pharmaceutical industry for tablets, capsules, and other solid dosage forms.
