What is Carrageenan‑Based Hydrogel Patches blister packaging machine?
This automatic carrageenan‑based hydrogel patches manufacturing machine is a complete turn‑key production line specially optimized for seaweed‑derived carrageenan hydrogel formulations, including kappa‑carrageenan and iota‑carrageenan raw materials. The integrated system covers vacuum homogenizing mixing, precise hydrogel filling, cooling-forming and sealing packaging, solving special rheological requirements of carrageenan hydrogel with high water‑holding performance. It supports mass production of cosmetic hydrogel eye patches, facial gel masks, cooling compress patches, transdermal medical hydrogel plasters and biodegradable seaweed‑based hydrogel products. Built‑in PLC touch‑screen control allows adjustable filling volume, production speed and patch dimension. Modular configuration is available for small‑batch pilot workshop and large‑scale industrial factory. We deliver custom hydrogel patch manufacturing equipment with full‑process technical support from formulation test to on‑site commissioning.
Application of blister packing machine
This custom‑modified blister packing machine is specially developed for the production of carrageenan‑based hydrogel eye patches. Different from standard blister equipment, it integrates an extended freezing cooling tunnel to realize in‑line gel condensation after hydrogel filling, solving the problem of low‑viscosity carrageenan hydrogel flowing and shape‑loss before gelling.
It is applied to mass production of single‑unit blister‑packed carrageenan hydrogel eye patches, seaweed‑derived cooling gel patches and small‑size cosmetic hydrogel plasters. The machine works as a key downstream unit matched with carrageenan hydrogel batching system. After hydrogel filling and in‑situ cooling solidification, finished individual eye‑patch blister units are output. It meets cosmetic‑grade hygiene requirements and supports continuous industrial production. This is a non‑standard customized blister solution, the extended freezing cooling tunnel is the core difference against general‑purpose blister machines.
Structure of blister packaging machine
The non‑standard customized blister machine for carrageenan‑based hydrogel eye patches consists of the following core functional sections, the whole machine frame is lengthened to accommodate the freezing cooling tunnel:
Blister Cavity Forming StationHeats thermoforming base film, thermo‑forms individual blister cavities for eye patches by vacuum/pressure forming. The cavity dimension is customized according to eye‑patch outline. It provides fixed‑shape packaging containers for subsequent hydrogel filling.
Carrageenan‑based Hydrogel Filling StationPrecise quantitative filling unit dispenses liquid carrageenan‑based hydrogel into each pre‑formed blister cavity. Filling volume is adjustable to match target gel weight of eye patches.
Extended Freezing Cooling Tunnel（Core Non‑standard Module）This is the key customized section which makes the whole machine longer. Liquid carrageenan hydrogel inside blister cavities passes through this low‑temperature channel to complete condensation and gel solidification. It prevents hydrogel flow, overflow and deformation before sealing, guarantees stable gelling performance for carrageenan system.
Aluminum Lidding Foil Heat‑sealing StationAfter hydrogel fully condenses into solid gel patches, aluminum lidding foil is covered on blister base. Controlled temperature and pressure heat‑sealing achieves hermetic sealing for each cavity, avoiding moisture loss of carrageenan hydrogel.
Punching & Die‑cutting StationThe sealed web is fed into punching unit to cut apart continuous web into single independent blister‑packed hydrogel eye‑patch products. Optional waste edge collection is equipped.
Auxiliary UnitsIncludes PLC servo control system, film unwinding modules, batch coding device, waste trimming & collection mechanism.
