What is the difference between a frozen bag and a quick-freezing bag, so let's first understand what is frozen and quick-frozen.
Here, the freezing, we are talking about the freezing of food, freezing refers to the process of freezing the liquid water in the meat into a solid state by low temperature method, the low temperature here is usually controlled at -5 ° C ~ -1 ° C.
Then let's talk about quick freezing. Quick freezing refers to quickly freezing food into tiny ice crystals, and can not seriously damage cell tissue, preserve the original taste of food, and extend the shelf life of food. Quick freezing generally controls the temperature between -30 ° C and -18 ° C.
Let's talk about the difference between a frozen bag and a quick-freezing bag.
1. Different packaging materials, freezer bags only need food bags that are resistant to cold and water, and quick-freezing bags need not only resistance to cold and water, but also certain barrier properties.
2. Different packaging purposes, freezer bags are generally limited to the storage of meat, frozen can not only store meat, but also can store fruits, vegetables and other categories.
3. The price of the frozen bag is different than the price of the quick-freezing bag. Because the quick-freezing bag needs a certain barrier property, the material that can achieve the barrier property is more expensive.
The above is the difference between the freezer bag and the quick-freezing bag. I believe that everyone has a certain understanding of the difference between the freezer bag and the quick-freezing bag. So when you consult the bag, the freezer bag or the quick-freezing bag, you must ask what you want. The bag that looks like, what needs to be stored, whether it needs to be puncture-proof, and how much the temperature of the frozen product is, so that you can quote you more accurately.
