Different packaging materials and forming principles: Blister packs may be divided into two main types: aluminum/plastic (thermoforming) blister packs and aluminum/aluminum (cold forming) blister packs.
The advantages of thermoforming blister pack:
It can visually examine the product through the transparent plastic; it is easy to reject the faulty blister card by inspecting with a camera or the naked eye.
The most basic material for the forming web is PVC; it is low-cost and offers the ease of thermoforming.
Because the cavity or pocket contains the item snugly, it can use a universal feeder, making it low-cost and easy to operate.
The disadvantages of thermoforming blister pack:
> The poor protective properties because of poor barrier against moisture ingress and oxygen ingress;
The advantages of cold forming blister pack：
The use of aluminum provides a near-complete barrier to water, light, and oxygen, extending the product’s shelf life.
The disadvantages of cold forming blister pack are:
> The slower speed of production compared to thermoforming;
> The lack of transparency of the package increases the difficulty for the inspection system to reject the faulty blister card;
The larger size of the blister card (aluminum cannot be formed with near-90-degree angles) increases the cost.
> The material of forming aluminum film is more expensive than PVC.
Because the cavity or pocket is larger than the item, the feeder should be dedicated, which increases cost and operational difficulty.
To take advantage of the above and overcome the disadvantage, this industry launched the third type of blister pack: aluminum/plastic/aluminum blister pack.
This type of Blister Machine adds one tropical aluminum forming station and a second sealing station, allowing the plastic thermoforming blister package to be sealed with the formed tropical aluminum again.
Because the item is filled in a a thermoforming pocket or cavity,, it can use a universal feeder; making it low-cost and easy to operate.
The inspection camera can easily detect the blister card fault because of the transparency of the thermoforming plastic.
The tropical aluminum has the same properties as cold-formed aluminum and can offer a nearly complete barrier to water, light, and oxygen, perfectly protecting the medicine.
The characteristics of Blister Packaging Line
The alu/PVC unit features a larger forming area and a rotary-style sealing station, thereby increasing speed.
The tropical alu forming station has a larger forming area, which requires a higher output capacity.
The second sealing station has a larger sealing area, allowing the plastic thermoforming blister package to be sealed with formed tropical alu at higher output capacity.
> The punch station can adopt the crossing type; the trimming waste is about 1mm between two blisters; it can save more material.
Thanks to the rotary sealing style (alu-PVC) and the larger tropical aluminum forming and sealing area, the machine achieves high output. For the size of 98mm*70mm, the output can reach 180 blister cards/minute (DPH260H3) and 270 blister cards/minute (DPH350H3).
The Caroning Machine is an intermittent-style machine, but thanks to its rotary carton pick-up device and continuous-motion blister conveyor chain, the machine can run at a higher speed than traditional cartoning machines.
> Adopt a long carton magazine.
The PVC thermoforming station
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).
