Today, many industries rely on thermoforming as one of the main technologies in blister packaging. However, as business trends change, it has become imperative for leading packaging companies to revisit the way thermoforming is done. Within the pharmaceutical industry, thermoforming is the most prevalent method in blister packing machines. Currently, experts forecast the global market for thermoformed plastic products to grow at 4% CAGR from GBP 7 billion in 2012 to GBP 8.5 billion by 2017. The packaging segment of thermoforming plastic products, which accounts for 80% of the total volume consumed worldwide, is also projected to increase at 4% CAGR, from GBP 797 million in 2012 to GBP 971 million by 2017. In line with this growth, there are certain trends that are defining the future of thermoforming.
Completely Thermoformed Blisters: In the recent years, FMCG and medical device companies are switching to a completely thermoformed packaging as compared with pre-made or thermoformed blisters which were heat sealed to pre-printed backing cards.
Sustainable Thermoforming: Being an energy-consuming process, packaging equipment manufacturers are investing heavily in R&D to make thermoforming a better process – ecologically and economically. This has even called for a relook at design boards and reformatting of parts to see how sustainability can be built into the machine.
ACG has taken thermoforming technique to a new level by lowering the draw forming cavity angle of a blister. Traditionally, blister packing machines produce blisters that have a draw forming cavity angle of 8°-10°. ACG successfully reduced it to 3° by increasing the depth of the cavity and decreasing the corner fillet radius. This helps in achieving sharper draw cavity, making compact blisters and savings on films of up to 10-15 mm.
