Types of Blister Packaging Machines
Packaging machinery is one of the essential core production equipment in modern manufacturing, especially in industries such as pharmaceuticals, health products, food processing, and chemicals. Among them, blister packaging machines are widely used in the pharmaceutical industry for blister packaging of solid tablets, capsules, pills, and oral liquids. Due to the high customizability of the forming molds, blister packing machines can accommodate different shapes and sizes of pharmaceutical products. Finished capsules and solid tablets produced by capsule filling machines and tablet presses can be integrated into a production packaging line with blister packaging machines. In this article, you will learn detailed information about blister packaging equipment, including its types, applications, and how to choose the right one. 1. What is a Blister Packaging Machine? A blister packaging machine is an equipment encapsulates products in transparent plastic or aluminum foil, commonly used for packaging pharmaceuticals, food, and small consumer goods. These machines use thermoforming or cold forming processes to shape plastic or aluminum foil into blisters, which are then used to enclose the products. This type of packaging not only protects the products but also effectively extends their shelf life, making it convenient for product display and transportation. 2. What is the Difference Between Thermoforming and Cold-Forming Blister Packaging Machines? You may have heard the terms "thermoforming" and "cold-forming." Choosing the right forming process depends on the product's characteristics and packaging requirements. Thermoforming Blister Packaging Machine Thermoforming blister packaging machines form blisters by heating plastic films, typically used for packaging with high transparency, commonly seen in the packaging of tablets, capsules, and similar products. This equipment heats the plastic and uses molds to shape the blisters, creating a uniform packaging structure. The main advantage is the high transparency, making it ideal for display packaging. Cold-Forming Blister Packaging Machine Cold-forming blister packaging machines use materials like aluminum foil, shaping them through a cold-pressing process. This method is particularly suited for products that are sensitive to light or prone to oxidation, such as certain pharmaceuticals. Cold-formed packaging is typically non-transparent but offers superior barrier protection, effectively shielding products from light, oxygen, and moisture.
