Milk packaging is mostly 250ml why

[Chinese Packaging Network News] In the purchase of milk, taste, brand, shelf life will become a nightmare for people with difficulty, but when it comes to capacity, it is much simpler.

In addition to the home-mounted version, most common milk is 200 to 250 ml, of which 250 ml is more. Not only the milk on the supermarket shelves, but also the amount of milk mentioned in various recipes and nutritious meals, all read “milk: 250ml”.

Are these seemingly coincidental numbers hidden in mystery? Today, we come to talk to you about 250ml milk packaging.

Milk packaging size related to?

In milk sold in supermarkets, milk is not the only value, and most of its selling price comes from packaging costs. In other words, the size of milk packaging is related to the cost.

Taking a box of 250ml of plain milk as an example, the market price is generally 3 to 5 yuan, and the price of Tetra Pak's packaging accounts for about 40% of the selling price.

Generally speaking, large-capacity milk (as we often call home) is more affordable than small-sized milk. Because of the same volume of milk, household packaging requires less packaging than small-volume milk. But for most people, small-capacity milk with a straw is more convenient and quicker.

The 250ml number has a secret?

Before answering why most of the commercially available milk is 250ml, we must first understand whether this is the case. For example, in Europe and the United States, the volume of milk is calculated as a pint, and a pint is equivalent to approximately 568 ml.

In many cases, the packaging of goods is closely related to the unit of measurement.

For example, referring to the capacity of 1 pint, many bottled water in China is generally 550ml in size. The daily use of cup capacity is related to the “ounce” (oz), the European and American unit of measurement.

Take the Starbucks cup type we are familiar with as an example, there are 8/12/24/31 four options, of which the smallest 8 oz is about 230ml converted.

The packaging of milk is also referenced to the "ounce" standard in the production process. Earlier, according to the standard of “8 ounces equals 230 ml,” milk packaging manufacturers in addition to producing 250 ml of this kind of packaging, there are also numbers such as 200ml, 280ml, 150ml, and all kinds of mess, but for the sake of convenience, they are mostly unified into 250ml. .

And a box of milk is usually 12 boxes, from Europe and the United States "dozen (dozon) twelve" concept. As a result, a box equals 250ml*12=3000ml, which is also more convenient to calculate.

250g milk has "delicious"?

In China, in addition to the popularity of 250ml packaging, there is also a portion of 250g of milk packaging. So what's the difference between 250ml and 250g?

In general, when choosing a unit of measurement, taking dairy products as an example, liquid milk uses more volume, which is ml, L, etc., while solid yogurt has g, kg, and other mass units because of inconvenient capacity measurement.

So when a bottle of milk is dressed in a liquid coat, what's the trick behind it when using a quality unit?

Simply put, because the density of milk is slightly greater than the density of water, a glass of 250g of milk is generally only 243ml, a full 7ml less than a cup of 250ml milk.

From the aspect of milk quantity alone, it does not seem to have much effect, but a dairy enterprise that annually produces 1.5 billion Tetra Pak covered milk, filling 1 ml of milk per box means at least reducing costs by 5 million yuan. A large part is the cost of packaging.

Oh, why do we have to specify 250ml of milk in a nutritious meal? Perhaps the biggest reason is that this type of milk is most likely to be bought in supermarkets.

Foreign milk prefers 200ml

Compared to the 250ml bottle of milk on the Chinese market, foreign milk is a lot of “stingy”, except for the large 1L package, which is mostly 200ml.

Because foreigners are more tricky?

In general, a person's amount of water is 200-250ml at one time. Considering that you may need to eat breakfast, snacks, or fruit when you drink milk, 200ml is actually more in line with eating habits. Your mother will never have to worry about drinking. The next whole bag of milk bulges.

At the same time, a small tip to share with everyone is that the milk packaging box, regardless of the net content of 200ml or 250ml, refers to the volume of milk in the box. Because there is room for filling milk, the volume of the box will be larger than that of milk.
