DPH390H3 | Tropical Rotary
In pharmaceutical packaging, blister packs traditionally fall into two main categories: thermoforming (Alu-PVC) and cold forming (Alu-Alu). Thermoforming offers highly cost-effective production, utilizing universal feeders and transparent PVC that simplifies faulty blister rejection via cameras or visual inspection. However, it provides a limited barrier against moisture and oxygen. Conversely, cold forming Alu-Alu provides a near-complete barrier to extend product shelf life, but it increases packaging costs, reduces production speed, and requires complex dedicated feeders due to its opaque, oversized pockets.
To eliminate these compromises, the industry introduced the third format: the Tropical Blister (Alu-PVC-Alu). This innovative solution adds a tropical aluminum forming and second sealing station to the traditional process. The product is filled into a transparent thermoformed PVC cavity—allowing for universal feeding and easy camera inspection—before being sealed again with formed tropical aluminum. This delivers the ultimate combination: the high efficiency, visual clarity, and low cost of thermoforming, combined with the near-absolute moisture, light, and oxygen barrier of cold-formed aluminum.
The Tropical Blister Machine DPH390H3 (Alu-PVC-Alu) stands as the flagship model within our tropical blister portfolio, engineered specifically to deliver massive capacity for ultra-high volume mass production. Featuring an unprecedented 390mm web width, this robust rotary packaging system utilizes an enlarged forming area and a high-performance rotary sealing station to maximize throughput. Furthermore, the system incorporates an advanced crossing punch technology that reduces trimming waste between blisters to just 1mm, significantly saving packaging materials while delivering pristine pharmaceutical protection.
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
The punch station can adopts the crossing type, the trimming waste is about 1mm between two blisters; it can save more material
There are two waste tanks collect waste material alternatively
The machine adopts the enclosed structure and safety cover

Blister Pack & Blister Packaging Machine Guide
Blister packaging is widely utilized across the pharmaceutical industry, where traditional packs force a compromise between transparency and barrier performance.
While standard thermoforming offers high-speed visual clarity, it lacks absolute moisture and oxygen barriers. Conversely, cold-formed Alu-Alu provides ultimate protection but increases footprint, eliminates bottom-up vision inspection, and reduces line speed.
The Tropical Blister (Alu-PVC-Alu) packaging machine cleverly resolves this dilemma. By integrating a secondary tropical forming and sealing station, it overlays a protective layer of cold-formable tropical aluminum over standard thermoformed blisters. This delivers near-absolute barrier protection matching cold-forming while retaining visual inspection capability and high output efficiency.
