Hey there! As a supplier of fish food blister packaging machines, I often get asked about how these nifty devices work. So, I thought I’d take a few minutes to break it down for you in a way that’s easy to understand. Fish Food Blister Packaging Machine
Let’s start with the basics. A fish food blister packaging machine is designed to package fish food in those little plastic blisters you’ve probably seen in pet stores. It’s a key part of the packaging process and can make a huge difference in how long the fish food stays fresh and appealing to customers.
The Overall Process
The working principle of a fish food blister packaging machine can be divided into a few main steps: plastic sheet heating, blister forming, product filling, sealing, and cutting. Let’s dig into each of these steps a bit more.
Plastic Sheet Heating
The first thing that happens in the process is the heating of the plastic sheet. This sheet is usually made of PVC, PET, or some other type of thermoplastic material. These materials are great because they can be easily softened when heated and then harden again when they cool down.
The plastic sheet is fed into the machine and passes through a heating section. Here, heaters are used to warm up the sheet to a specific temperature. The temperature is super important – if it’s too low, the plastic won’t be soft enough to form the blisters properly. If it’s too high, the plastic might melt or get damaged. Most machines use infrared heaters or hot air to heat the plastic sheet because they’re efficient and can heat the sheet evenly.
Blister Forming
Once the plastic sheet is nice and soft from the heating process, it’s time to form the blisters. This is done using a mold. The softened plastic sheet is placed over the mold, and then either air pressure or vacuum is applied.
If air pressure is used, compressed air is forced against the plastic sheet, pushing it into the cavities of the mold. This creates the shape of the blisters. On the other hand, if vacuum is used, air is sucked out from under the plastic sheet, and the atmospheric pressure pushes the sheet into the mold cavities.
The mold is designed to have the exact shape and size of the blisters you want for your fish food. So, whether you need small, medium, or large blisters, the mold can be customized to fit your requirements.
Product Filling
After the blisters are formed, it’s time to fill them with fish food. This is usually done using a filling system, which can vary depending on the type of fish food. For dry fish food, a volumetric filling system is often used. This system measures a specific volume of the fish food and then dispenses it into each blister.
For example, if you’re packaging fish flakes, the volumetric filling system will use a rotating disk or a piston to measure out the right amount of flakes for each blister. For wet or semi – wet fish food, a different type of filling system might be used, like a pump – based system that can handle thicker substances.
The filling process needs to be accurate to make sure that each blister has the right amount of fish food. This is not only important for the customer but also for the overall quality and consistency of your product.
Sealing
Once the blisters are filled with fish food, the next step is to seal them. A lidding film is used for this purpose. The lidding film is usually made of aluminum foil or a plastic – based material. It’s placed on top of the filled blisters.
The sealing process involves applying heat and pressure to the lidding film and the plastic blisters. This melts the surfaces of the two materials together, creating a strong seal. The sealing temperature and pressure need to be carefully controlled. If the temperature is too low, the seal might not be strong enough, and the fish food could be exposed to air and moisture, which can reduce its shelf – life. If the temperature is too high, it could damage the fish food or the packaging materials.
Cutting
The last step in the process is cutting. After the blisters are sealed, the continuous sheet of blisters needs to be cut into individual packages. A cutting die is used for this purpose. The cutting die is designed to cut through the plastic sheet and the lidding film along the edges of each blister.
There are different types of cutting methods, including mechanical cutting and laser cutting. Mechanical cutting uses sharp blades to cut through the materials, while laser cutting uses a high – intensity laser beam. Laser cutting is often more precise and can create cleaner edges, but it can also be more expensive.
