Types of Automatic Blister Packaging Machine
Rotary Blister Packaging Machine: Rotary blister packaging machines are high-speed machines that can produce a large number of blister packs per minute. They are suitable for mass production and are often used in industries such as pharmaceuticals, food, and consumer goods.
Flat-plate Blister Packaging Machine: Flat-plate blister packaging machines are versatile machines that can handle a wide range of products and blister pack sizes. They are suitable for small to medium-scale production and offer flexibility in terms of customization and changeover.
Thermoforming Blister Packaging Machine: Thermoforming blister packaging machines use heat to form the blister cavities on a roll of plastic film before filling them with products. They are ideal for packaging products with irregular shapes or sizes and offer good visibility of the packaged product.
Cold Forming Blister Packaging Machine: Cold forming blister packaging machines use pressure to form the blister cavities on aluminum foil before filling them with products. They are commonly used for pharmaceutical products that require protection from moisture, light, or oxygen.
Skin Packaging Machine: Skin packaging machines use a different technique where the product is placed on a card or film, and then a heated film is draped over the product, creating a skin-tight seal around it. This type of packaging is often used for displaying products in retail settings.
Blister Sealing Machine: Blister sealing machines are used to seal filled blisters with a backing card or film to create the final package. They come in various configurations, including manual, semi-automatic, and fully automatic models.
The working principle of an automatic blister packaging machine can be broken down into several key steps:
Feeding: The first step in the process involves feeding the packaging material, typically a roll of plastic film or aluminum foil, into the machine. The material is then guided through the machine using rollers to ensure smooth and consistent movement.
Forming: The packaging material is then heated and molded into the desired shape to create individual blister cavities that will hold the products. This forming process is usually done using heated molds or dies that shape the material into the required blister pack design.
Product Filling: Once the blister cavities are formed, the products are loaded into each cavity either manually or automatically using a product feeding system. The products are placed precisely in each cavity to ensure accurate filling.
Sealing: After the products are loaded into the blister cavities, a backing material (usually another layer of plastic film) is sealed over the top to enclose the products securely within each cavity. This sealing process can be done using heat sealing, pressure sealing, or ultrasonic welding depending on the type of machine.
Cutting and Packaging: Once sealed, the blister packs are cut into individual units using cutting tools integrated into the machine. The finished blister packs are then collected and packaged for distribution.
Materials Used In Blister Packaging
Packaging Film
A plastic film can be used for blister packaging because of its sufficient barrier performance to carbon dioxide, oxygen, water vapor, high mechanical strength, and high transparency for not easy to crack.
Besides, rigid plastic films like cellulose, vinyl resin, polystyrene, polyvinylidene chloride, polyvinyl chloride, and polystyrene, etc, can be used for blister packaging. Currently, the most widely used pharmaceutical blister packaging material is PVC plastic sheet because of its good barrier performance against the light, water vapor, and the unusual smell of plastic sheet. But, since PVC is not ideal for moisture resistance, it's advisable to use polyvinylidene chloride (PVDC) or its composite materials for future use.
Substrate
White cardboard is usually used for blister packaging. It's made of bleached kraft wood pulp, or can be made with the recycled board covering the base layer with white paper.
The size, shape, and quality of the cardboard are considered when using the white cardboard. The thickness range of the whiteboard substrate is 0.35-0.75mm, while it is 0.45-0.60mm for the normally used board. Also, make sure that the substrate surface is white and glossy, with good quality printability, and the heat sealing coating could be firmly coated. Make sure that the substrate and blister are combined closely after the heat seating coating is melted, to prevent the contents from falling out.
Coating Material
The coating material should be compatible with the substrate and the blister. Besides, the temperature should be relatively low so that it can be sealed quickly without damaging the blister film. As the soluble vinyl-resin and water-resistant acrylic resin have good transparency, good luster, and heat sealing capacity, they can generally be used.
