The Tropical Blister (Alu/PVC/Alu) format was developed to combine the operational advantages of standard thermoforming with the premium protection of cold forming. It utilizes PVC thermoforming for cost-effective universal feeding and transparent camera inspection, followed by an additional tropical aluminum sealing station that provides a near-complete barrier against moisture, light, and oxygen.
Engineered specifically for this advanced packaging format, this dedicated Blister Line features enlarged forming and sealing areas to maximize output capacity. It successfully addresses the traditional drawbacks of cold-forming—such as slower speeds and expensive dedicated feeders—while delivering the ultimate shelf-life protection for critical pharmaceutical products.
Because the item is filled in thermoforming pocket so it can adopt universal or vibratory feeder, it is low cost and ease of operation
The alu/pvc sealing station adopts rotary style thus increase the machine speed
While alu/pvc sealing and embossing the tropical alu is transferred to tropical alu forming station
The tropical alu forming station has larger forming area archive larger output requirement
The second sealing station has larger area to allow the plastic thermoforming blister package to be sealed with formed tropical alu at higher output capacity
After second sealing, the alu-pvc-alu web moves to punch station
There are two waste tanks collect waste material alternatively
The punch station can adopts the crossing type, the trimming waste is about 1mm between two blisters; it can save more material
Inside the magazine, the blister cards are counted when they free fall via the servo-motor, and are then held in position by the transfer belt.
The Leaflet are isolated from the bottom from a pile magazine, then pulled off and folded. It can make the leaflet fold one to four folds according to customer’s demand
The rotary carton pick-up suck the cartons from the carton magazine
The inserter device can push the blister cards and leaflet into the carton.
The rotary carton pick-up suck the cartons from the carton magazine then places them in carton conveyor chain
Long carton magazine
In carton conveyor chain the cartons are closed automatically. Adopts digital position indicator achieves straightforward adjustment
After actions of inserting of blister cards and leaflets into cartons, embossing and closing, the cartons were discharged automatically
Pinhole detection system for quality assurance of blister packaging (optional).
