Blister packaging is now a versatile and widely adopted option for packaging products that offers both protection and visibility. The efficiency of packaging with blisters is not just in its design, but also in the selection of appropriate materials. In this article, we’ll explore the details of blister packaging and examine the most important materials used, recent advancements as well as the increasing significance of environmentally-friendly alternatives.
Materials Used to make Blister packaging:
PVC (Polyvinyl Chloride): PVC is an extremely popular material used in blister packaging because of its clarity, flexibility, and cost-effectiveness. It provides excellent visibility for the product, allowing consumers to look at it without opening the packaging. PVC is also renowned because of its barriers that protect the contents from external and internal contaminants as well as moisture.
PET (Polyethylene Terephthalate): PET is another popular material for blister packaging. It has the same transparency as PVC however, it is much more environmentally green and recyclable. PET is known for its durability and strength and is suitable for packaging a range of items, ranging from food items to electronics.
RPE (Recycled PET): As sustainability is a major concern in packaging recycling, the use of recycled PET in blister packaging is gaining traction. RPET helps reduce the environmental impact by using recycled post-consumer content. This is in line with the increasing demand for eco-friendly packaging solutions.
The APET (Amorphous Polyethylene Terephthalate): APET is a clear and tough plastic that gives great strength. It is commonly employed in the manufacture of blisters for products which require a stronger and more secure enclosure. APET is renowned for its ability to maintain its shape even in different temperatures.
Biodegradable and Compostable Materials: With increasing awareness of environmental issues, blister packaging makers are looking into biodegradable and compostable options. These materials aim to minimize the environmental impact by breaking down naturally, contributing to a more environmentally sustainable packaging option.
Recent Advancements in Blister Packaging Materials:
Intelligent Packaging: Technology advancements have resulted in the introduction of smart packaging features into blister packs. It includes RFID (Radio-Frequency identification) tags and QR codes, which improve the traceability of packages and offering consumers an interactive and informative experience.
Antimicrobial Coatings: In response to increased health concerns, some of the packaging materials for blisters are now fitted with antimicrobial coatings. The coatings prevent any growth in bacteria and other microorganisms on packaging surface, adding an extra layer of protection for the item being packaged.
Lightweighting and Reduction of Material: Manufacturers are continuously seeking ways to decrease the amount of the amount of material used in blister packaging while maintaining its protective properties. This lightweighting approach does not just conserve resources, but also lowers the cost of transportation and environmental impact.
Customization Technologies: Advanced printing and customization technologies allow for intricate and high-quality graphics on the packaging of blisters. This improves the aesthetic appeal of products, making them more attractive to consumers. Customization also extends to unique designs and shapes that are tailored to specific items.
Environmental Concerns for Blister packaging:
Recyclability and circular economy: The push for recyclable materials used in packaging for blisters is in line with the larger objectives of an economy that is circular. Designing packaging that can be easily recycled contributes to the reduction of plastic waste and promotes the responsible utilization of resources.
Bio-based Plastics: Bio-based plastics derived from renewable sources are gaining recognition as an alternative to fossil fuels. These plastics, like PLA (Polylactic Acid) provide a smaller carbon footprint when compared to conventional plastics, and further support eco-friendly blister packaging.
Closed-Loop Systems: Certain manufacturers are implementing closed-loop processes, in which post-consumer recycled materials are utilized for the creation of new packaging for blisters. This method helps make an environmentally sustainable supply chain and decreases dependence on virgin materials.
Conclusion:
Blister packaging equipment plays crucial roles in the success of this method of packaging, influencing the product’s visibility as well as its protection and environmental impact. As sustainability and technology continue to impact the packaging industry, blister packaging is evolving with a focus on smart characteristics, antimicrobial properties and eco-friendly materials. The choices made in blister packaging supplies today not only affect the effectiveness of the packaging, but they can also help to create a more sustainable and responsible future for the industry.
