Hey there! I’m a supplier of fish food blister packaging machines, and I often get asked about the drying time of the blisters produced by these machines. In this blog post, I’m going to share with you everything you need to know about the drying time, factors that affect it, and how to optimize the process.

What Is Blister Packaging?<\/h3>\n

First things first, let’s talk a bit about blister packaging. It’s a popular way to package all sorts of products, including fish food. The process involves creating a cavity in a sheet of plastic\u2014usually PVC or PET\u2014and then sealing a paperboard or another plastic layer over it to enclose the product. The plastic blister protects the fish food from moisture, air, and dust, keeping it fresh for longer.<\/p>\n

Why Drying Time Matters<\/h3>\n

Drying time is crucial in the blister packaging process. If the blisters aren’t dry enough, the packaging may not seal properly. That can lead to all sorts of issues, like the fish food getting contaminated by air or moisture, which shortens its shelf life. On the other hand, if you over – dry the blisters, it can waste energy and time, driving up production costs.<\/p>\n

Factors Affecting Drying Time<\/h3>\n

1. Material of the Blister<\/h4>\n

The type of plastic used for the blister has a big impact on drying time. For example, PVC has different moisture absorption and evaporation properties compared to PET. PVC typically has a higher moisture content and may take longer to dry. PET, on the other hand, dries a bit faster in general. But it can also be more sensitive to temperature changes during the drying process.<\/p>\n

2. Thickness of the Blister<\/h4>\n

As you’d expect, thicker blisters take longer to dry. Thicker plastic has more material that needs to have its moisture removed. So, if your fish food blister packaging uses a thicker plastic sheet, you’ll need to factor in a longer drying time. For instance, a 0.5 – mm thick blister will dry much faster than a 1 – mm thick one.<\/p>\n

3. Drying Method<\/h4>\n

There are several ways to dry the blisters, and each method has its own drying time. The most common methods include hot – air drying, infrared drying, and microwave drying.<\/p>\n
