Aluminium Foil for Medicine Packaging

 Metal packaging material refers to a material that is rolled into thin sheets after special treatment and used for product packaging. It is also known as the "four major packaging materials" along with glass, plastic, and paper. It is one of the commonly used packaging materials for pharmaceuticals. Tin-plated iron sheets appeared in Czechoslovakia as early as 1200 AD; British tinplate technology was born in Britain in 1810; aluminum plates and aluminum foil for medicine packaging appeared in the early 20th century.

Metal packaging materials mainly include low carbon steel sheets, tinned steel sheets, non-tinned steel sheets, aluminum foil and aluminum alloy sheets. However, due to the particularity and strict requirements of pharmaceuticals, low carbon thin steel sheets and non-tinned steel sheets are used in food, beverage and industrial fields, but has few applications in the medical field. There are two main types of commonly used medicinal metal packaging materials:

1. Tin-plated steel plate: It is often used for packaging of sprays and aerosols;

2. Aluminum products( medicine aluminum foil and aluminum tubes): It is widely used in the packaging of tablets, capsules, granules, creams, ointments, gels and other solid or semi-solid preparations; aluminum products can also be combined with aluminum-plastic combination cover and the glass container.

Tablet bottles are used to package solid drugs such as tablets and capsules. These drugs are easily affected by moisture and may become ineffective or even deteriorate when exposed to water vapor. How to ensure the stability of the drugs within the validity period and avoid being affected by external moisture and deterioration? Its packaging can meet this demand very well.

Tablet bottles are generally made of plastic materials processed through various processes. First of all, these plastic products have good barrier functions against external water vapor, impurities, etc., and are good materials for pharmaceutical packaging, especially tablet drugs that are afraid of moisture.

Secondly, the caps of tablet bottles are generally sealed with pharma lidding foil. Aluminum foil is a hot stamping material that is directly rolled into thin sheets of metallic aluminum. Adding an aluminum foil sealing gasket between the body and cap of the medicine bottle can ensure the sealing of bottles.

The gasket of this sealing method is composed of adhesive sealing layer, aluminum foil, weak adhesive layer, cardboard elastomer, etc. The aluminum foil gasket is embedded in the bottle cap to expose the aluminum foil, and then applied to the bottle body to tighten the bottle mouth, using electromagnetic induction.

Medicinal sealing aluminum foil gaskets are mainly used inside various types of medical bottle caps. Its main function is to block direct contact between the bottle mouth and the inside of the bottle cap, thereby preventing contact between the inside of the bottle cap and the outside air. It can keep the quality of medicines unchanged for a long time. The aluminum foil 1100 is chosen.
