Unraveling the Dimensions: A Comprehensive Guide to Blister Pack Sizes

Hello everyone,

Today, we delve into the world of packaging, specifically focusing on blister packs. The question at hand is, What size are blister packs? While it may seem straightforward, the answer is far from simple. Blister pack sizes are as diverse as the products they protect, ranging from small pharmaceutical tablets to large consumer electronics.

Blister packs, also known as clamshell packaging, are pre-formed plastic packaging used for small consumer goods, foods, and pharmaceuticals. The primary component of a blister pack is a cavity or pocket made from a thermoformed plastic. This usually has a backing of paperboard or aluminum foil or plastic.

The size of a blister pack is determined by several factors, including the size of the product, the required barrier properties, the intended market (pharmaceutical, food, etc.), and the necessary information that needs to be printed on the pack.

In the pharmaceutical industry, for example, blister packs are typically small, designed to hold a specific dosage of medication. These packs are usually around 2.5 inches by 3.5 inches, but can vary based on the size and quantity of the pills.

In the consumer goods industry, blister packs can range significantly in size. For small items like batteries or toys, the packs might be as small as 3 inches by 4 inches. For larger items like power tools or electronics, the packs could be as large as 12 inches by 15 inches or more.

It’s also important to note that the size of the blister pack can impact the product’s visibility, security, and the amount of information that can be displayed. Larger blister packs allow for more product visibility and more space for product information, but they also take up more shelf space and may provide less product security.

In terms of the thickness of the blister pack, it generally ranges from 0.020 inches to 0.030 inches for standard applications. However, for heavier items, the thickness can go up to 0.040 inches to 0.060 inches.

In conclusion, the size of blister packs is not standardized and can vary greatly depending on the product, industry, and specific requirements. As such, it’s crucial for manufacturers and retailers to work closely with packaging professionals to determine the most appropriate size for their blister packs.
