Jul 08, 2024

Speaking of bubble cover packaging, many people may not be familiar with what it is. However, blister packaging this packaging method has been widely penetrated into various areas of our daily life. For example, from small to street convenience stores, large shopping supermarkets, hardware stores, hospitals, pharmacies, stationery and daily products, blister packaging can be seen everywhere in our lives. Then why is this packaging so popular and widely used? Then let me explain in detail what is blister packaging and its advantages and disadvantages.

 

What Is Blister Packaging?

Blister packaging is a modern common and widely used packaging method, especially suitable for small goods, such as drugs/health products, disposable medical equipment, solid food and liquid food, cosmetics, biochemical and daily chemical products, stationery, small hardware accessories, toys, auto parts, agricultural seeds, electronic products and other products. The basic principle of blister packaging technology is to encapsulate the product in a pre-formed transparent plastic blister, and then seal the blister and a backplane (bottom plate) together. Below I will give you a detailed introduction to the blister packaging.

The Composition Of Blister Packaging

1. Blister cap:

It is generally made of plastic material (PVC) or metal material (aluminum foil) by heating blow molding or mold pressing, so that it forms one or more raised cavities to accommodate the product. The blister can also be customized according to the shape of the product mold to form a special shape of the cavity to meet different needs. The following is the introduction of common materials for blister molding.

1.1 Plastic material of bubble cap:

Polyvinyl chloride (PVC) : high transparency, easy to form, cheap.

Polyethylene terephthalate (PET) : good barrier, strong chemical resistance.

Polypropylene (PP) : Good heat resistance, suitable for high temperature sterilization.

1.2 Metal material of bubble cap:

Aluminum foil: the most commonly used backplane material, excellent barrier, easy to open after sealing.

Aluminum-plastic composite material: combining the advantages of plastic box aluminum foil.

2. Back Plate:

The backplane of drug blister packaging is commonly used as aluminum foil material, and can also be used according to the needs of different products, such as plastic, cardboard, dialysis paper or other composite materials, as the support and closed surface of the blister can also print display information, such as brand name and logo, promotional activity information, product information, instructions for use, warning information, etc.

3. Sealing Layer:

The connecting part between the blister cap and the back plate is tightly combined by using heat sealing, cold sealing or bonding to ensure the tightness and integrity of the package.

In the selection of blister packaging, the choice of material should consider a number of factors, such as product characteristics, size and shape, shelf life requirements, production processes, use of the environment, regulatory requirements, cost, environmental factors and consumer convenience.

 

What Are The Advantages Of Blister Packaging?

Blister packaging, as a practical and economical packaging solution, can meet the needs of different industries to protect and display products and achieve mass production. Next, let's understand what advantages blister packaging has.

1. Product Display Visibility:

Through the transparent bubble cover, customers can directly see the product, which can fully display the information of the product, thereby increasing the trust and confidence of customers. This not only improves the purchase rate of customers, but also reduces the problem of after-sales service.

2. Safety Protection:

Blister packaging provides a safe protection space for the product due to the material and raised structure, reducing the damage that may be caused by the product during transportation and storage. Ensures the integrity of the product into the hands of the customer.

3. Extend Shelf Life:

Blister packaging because of its material has excellent barrier effect, can effectively moistureproof, anti-light, anti-oxidation, reduce product contact with the outside world, maintain the stability of the product, thereby extending the shelf life of the product.

4. Tamper-proof Security Function:

The transparent blister and aluminum foil sealed back make it easy to identify any signs of tampering, ensuring product integrity and safety from the time of purchase to the consumer. Can significantly improve consumer confidence in the product, thereby increasing product sales.

5. Product Health and Safety:

Each individual blister allows the product to be sealed individually, and the opening of one blister will not affect other blisters, reducing the risk of cross-contamination, and facilitating the long-term use of consumers who will not affect the quality and shelf life of other independent blister products because of the opening of a package.

6. Easy to Carry:

Because the blister packaging is light and smooth, and can be easily torn through the design, it is convenient for consumers to divide the products of the whole board into multiple independent small packages according to their needs, which is convenient to carry out daily use and storage.

7. Quantitative Control:

For drugs and health care products, the independent blister design is convenient for consumers to access on demand, which helps patients to use drugs for a long time according to the doctor's advice.

8. Information Display:

The backplane of blister packaging provides sufficient space for printing display information on the back, such as brand information, product information, instructions for use, precautions, bar code/two-dimensional code for information traceability.

9. Personalized Customization:

Blister packaging because the general use of plastic (PVC) material, through heating blow molding or mold pressing molding characteristics, so as to meet the shape, size and personality design requirements of different products. The backplane of the blister packaging can be fully printed to display different information, highlight the characteristics of different products and promotional information, attract customers' attention and improve customers' willingness to buy.

10. High Production Efficiency:

The standardized design of blister packaging is convenient for mass production, and large-scale production can be achieved with automated production line equipment such as aluminum-plastic blister packaging machines, thereby reducing unit costs and a large number of human resource costs. Blister packaging machine integrates material conveying, heating or mold cold pressing forming, filling (rotary disc feeding, orbital station feeding, mechanical hand feeding, etc.), heat sealing, blanking and cutting, forming a complete automatic production process. This integrated design greatly simplifies the production process and reduces the material handling and manual intervention in the intermediate links, thus significantly improving production efficiency.

 

 

What Are The Disadvantages Of Blister Packaging?

Blister packaging is widely used in the process but also because of its shortcomings can not be ignored, next, let us understand this information together, so that you can choose to use more fully understand and choose.

1. Environmental Impact Issues:

Most of the blister packaging materials often use composite materials, resulting in its components are difficult to separate and recycle, and traditional plastic materials are difficult to degrade themselves in the natural environment, long-term use of large amounts of pollution of the natural environment is difficult to solve. This problem has also prompted the continuous development and updating of materials to achieve the purpose of environmental protection.

2. High Cost:

When packaging smaller products such as drugs, compared with bags or bottles, blister packaging because the unit area is larger, and the packaging cost of each plate of pills is relatively fixed, resulting in a large number of unit costs will not be significantly reduced, packaging materials and consumption costs are higher. Because different products need different sizes and shapes of molds, once the mold is completed, the cost of change is relatively high, so blister packaging is not suitable for small batch or customized production.

3. Volume Increase:

Blister packaging because of the need to form a raised cavity to accommodate a single drug and part of the backplane of the extended safety area, resulting in the same number of drugs, blister packaging takes up more space. As a result, more space is taken up for shipping and product storage.

4. Open Inconvenience and Safety:

For the elderly and consumers with inflexible hands, it may be difficult to remove the medicine. And blister packaging due to heating or pressing molding resulting in sharp edges of the blister plate, if improperly operated when opened, may cause minor scratches.

5. Irreparable Damage:

Due to the tamper-proof characteristics of blister packaging, once the blister packaging products are improperly handled in the production, transportation and storage process, the blister may be damaged beyond repair due to extrusion, and usually can only be scrapped, resulting in an increase in finished products and waste to a certain extent.
