Blister pack

A blister pack is a type of packaging used for small consumer goods, food, and pharmaceuticals. Blister packs are useful for protecting products against external factors, such as humidity and contamination, for extended periods. They are also used to provide a degree of tamper resistance and to improve the shelf life of products.

Components

Blister packs typically consist of two main components:

• The blister, which is a cavity or pocket made from a formable web, usually a thermoformed plastic.
• The lidding, which is a material that seals the blister. This is often made from aluminum foil, paperboard, or a combination of both.

Types of Blister Packs

There are several types of blister packs, including:

• Face-seal blister: The blister is sealed to a piece of cardboard.
• Full-face seal blister: The blister extends to the edge of the card, providing a more secure seal.
• Trapped blister: The blister is trapped between two cards, which are sealed together.
• Slide blister: The blister is not sealed to the card but rather allows the card to slide in and out.

Applications

Blister packs are widely used in various industries:

• In the pharmaceutical industry, they are used to package tablets, capsules, and other dosage forms.
• In the food industry, they are used for packaging items like cheese, meat, and snacks.
• In the consumer goods sector, they are used for packaging items such as toys, hardware, and electronics.

Advantages

Blister packs offer several advantages:

• They provide a high level of product protection.
• They are tamper-evident, which helps in ensuring product safety.
• They are cost-effective and can be produced in large quantities.
• They offer good visibility of the product, which can enhance marketing efforts.

Disadvantages

Despite their advantages, blister packs also have some drawbacks:

• They can be difficult to open, especially for elderly or disabled individuals.
• They are not always environmentally friendly, as they often use non-recyclable materials.

Manufacturing Process

The manufacturing process of blister packs involves several steps:

• Thermoforming: The plastic film is heated and formed into the shape of the blister.
• Filling: The product is placed into the blister.
• Sealing: The lidding material is sealed to the blister, usually using heat and pressure.
