Product Overview
Different packaging materials and principles of forming, Blister packs may be divided into mainly two types: aluminum/plastic (thermoforming) blister pack and aluminum/aluminum (cold forming) blister pack.
Thermoforming Blister Pack Analysis
✔Advantages: Visual examination through transparent plastic makes it easy to reject faulty cards; low-cost PVC material; compatible with universal feeders for easy operation.
✘Disadvantages: Poor barrier properties against moisture and oxygen ingress.
Cold Forming Blister Pack Analysis
✔Advantages: Aluminum offers a nearly complete barrier for water, light, and oxygen, extending product expiration dates.
✘Disadvantages: Slower production speeds; lack of transparency; larger card size increases material and operational costs.
The Advanced Solution: Aluminum/Plastic/Aluminum
To maximize advantages, this industry launched the third type: aluminum/plastic/aluminum blister pack. This machine adds one tropical aluminum forming station and a second sealing station. It offers the visibility of thermoforming during inspection and the high protection of cold-forming aluminum for the final seal.
Key Characteristics
◈High Speed: Adopts larger forming areas and rotary style sealing to significantly increase output.
◈Material Efficiency: The punch station uses crossing type technology, with trimming waste of only 1mm between blisters.
◈High Capacity: Output reaches up to 180 cards/min (DPH260H3) and 270 cards/min (DPH350H3).
◈Advanced Cartoning: Intermittent style with rotary pick-up device and continuous motion conveyor chain for superior speed.
Frequently Asked Questions
What are the main types of blister packaging this machine handles?
The production line is designed for Aluminum/Plastic (thermoforming), Aluminum/Aluminum (cold forming), and the hybrid Aluminum/Plastic/Aluminum (tropical) blister packs.
How does the tropical aluminum station benefit the product?
It combines the visibility of PVC packs for inspection with the superior barrier properties of aluminum to protect medicine from water, light, and oxygen.
Is the machine material-efficient?
Yes, the punch station utilizes a crossing type design which reduces trimming waste to approximately 1mm between blisters, significantly saving material.
What is the production speed of the DPH series?
The DPH260H3 can produce up to 180 cards per minute, while the larger DPH350H3 reaches up to 270 cards per minute for standard sizes.
Can the machine handle leaflet insertion?
Yes, the integrated cartoning system can fold leaflets in one to four folds according to specific customer requirements before insertion.
Does the machine support computerized operation?
Absolutely. The system is fully computerized and utilizes servo-motors for precise counting and blister card transfer.
