Certain blister pack variations are designed to serve various purposes. These types include:
Standard Blister Packs
The standard type consists of a plastic formed shell and a paper or plastic sealant cover. This pack is used to package individual doses of medication and is thus mostly common in the pharmaceutical industry.
Clamshell Blister Packs
This type of blister pack is fully enclosed, with the blister and backing sealed together along a hinge. Such designs are more robust and allow better product visibility. This type of pack is widely used in the packaging of consumer electronics, toys, and hardware.
Slide Blister Packs
The slide blister pack consists of a blister mounted on a cardboard sliding base. This design allows for multiple items to be packed in a single unit, such as cards, tools, or accessories. Such packs provide both product visibility and easy storage.
Full-face Blister Packs
These packs have a plastic bubble that covers the entire front surface of the package. This design is ideal for showcasing products that need high visibility during display, such as cosmetics, jewelry, or small gadgets.
Shaped Blister Packs
Shaped blister packs are customized blisters that are molded into specific shapes to accommodate unique products. This design is often used for toys, promotional items, or specialized tools that require a captivating and distinctive packaging form.
Face Seal Blister Packs
This type of pack seals the plastic blister only on the edges to a paper or cardboard backing. This design allows for good product visibility and provides space for printing important product information on the back. Such packs are commonly used for small items like stationery, electronics, and batteries.
To create effective blister pack packaging, several important factors should be considered.
Sustainability
With the current increase in environmental concerns, the materials used in making blister packs must be recyclable or biodegradable. Eco-friendly packaging materials reduce carbon footprints and waste, positively impacting a company's image. In addition, using renewable materials helps contribute to environmental protection and conservation.
Regulatory Compliance
Depending on the industry, these packs may have to conform to certain governmental regulations. Such requirements ensure that the packaging contains proper labeling, child resistance features, or tamper-evident properties. To avoid incurring extra costs in redesigning the packs, such compliance considerations should be included in the design process from the outset.
Cost of Production
The design of the blister pack should be as efficient as possible to control production costs. While selecting premium materials and doing a detailed design may increase the total cost, efficient processes may lower it. Balancing design features with manufacturing capabilities is important to keep the cost within acceptable ranges to the consumer and supplier alike.
Material Properties
The selected materials for the blister pack should be able to provide adequate protection to the product. Such materials should be able to prevent moisture, air, and physical damage to the product, hence ensuring its longevity. Common materials used include PVC, PET, and thermoforming plastic, renowned for their durability and strength.
Design Functionality
Considerations of design must also address the functionality of the blister packaging. This includes the product protection, ease of opening, and whether the pack is able to extend the shelf life of the packed goods. Additionally, accommodating product display and ensuring that the package serves its primary function without difficulty are crucial.
Consumer Experience
Blister pack design should include considerations of user-friendliness and the overall customer experience. It considers how the packed product is well illustrated, instructions on using the product are accessible, and the packing process of the product is simple and easy. Good design also considers the aesthetic appeal of the package and the perceived value by the consumer.
Selecting an ideal blister pack design will require answering the following questions.
What is the nature of the product?
Some products require more protection than others, such as those that are fragile or perishable. For instance, selecting a robust blister pack would be more appropriate for electronics to protect them from physical damage. PETG plastic blister packaging provides a durable and protective encasement for sensitive items such as electronics, ensuring their safety during transport and storage.
How is the user experience important?
Consideration should be given to how consumers will access and use the product. Will the pack be easy to open, or will special techniques be required for such a simple process? Also, will the packaging enhance the display of the product, hence adding to its attractiveness and usefulness?
Are there specific regulations that have to be considered?
Various industries, such as pharmaceuticals, may have rules about packaging to ensure safety and proper product utilization. It is crucial to understand the regulatory requirements that apply to the product in order to incorporate necessary design elements, such as tamper-proof features or child-resistant packing.
What are the cost implications?
While a good blister pack design may require a significant investment, measures should always be sought to minimize the costs. A more complicated pack may be more expensive to design but could lead to enhanced product protection and marketing. Sometimes, too much emphasis on cost-cutting may affect the fundamental features of the blister pack and its selling appeal.
Blister packs offer versatile packaging solutions across various industries.
Pharmaceuticals
