The difference between aluminum and iron

Aluminum cans:

1. Convenience: Aluminum cans are now easy to store and carry because of their light weight.

2. Environmentally friendly: Waste aluminum cans can be processed into aluminum ingots, and then aluminum cans.

Therefore, it is a very environmentally friendly container material.

In addition, most aluminum cans are fitted with downforce safety tabs, which, in addition to being safer to open drinks, do not require environmental contamination by discarding the tabs.

3. High tightness: because it is easy to open the can and has excellent tightness, it is easier to preserve the flavor of drinks than ordinary packaging materials. Aluminum cans are designed for cold storage and normal temperature storage of drinks packaging, not designed for heating, especially aluminum cans containing carbon dioxide is definitely not suitable for direct heating drinking.

The barrier to air and other volatile gases in the packaging container is very important for the preservation of nutrients and sensory quality.

The comparison of various juice packaging containers showed that the oxygen transmittance of the container directly affected the Browning of juice and the preservation of vitamin C.

Low oxygen transmittance of metal cans, glass bottles and aluminum foil glue layer, cartons of vitamin C preservation is better, and the best with iron cans.

With regard to canned drinks, why do we need iron, aluminum cans?

Beverages are divided into acidic products and low-acid products, with PH4.6 as the boundary. Low-acid products such as coffee, tea and milk tea must be put into sterilization kettle for sterilization, and must rely on the strong support of tinplate to resist pressure.

So low acidity is mostly in cans.

Acidic products such as soda water, juice, etc. can be directly filled with aluminum cans can be used, but aluminum cans are too soft must be used for internal pressure support with nitrogen, acid can be used in aluminum cans, but can also be used in iron cans.

Recently, although there are a small number of nitrogenous can be added into the sterilization kettle products.

But generally the difference between the aluminum foil package and the tin can and the aluminum can is what?

Eating aluminum foil packaging often affects the nervous system. Eating, drinking and having fun are very convenient in Taiwan, but for the sake of convenience, they produce an amazing amount of garbage after the fun.

In the field of beverages, a significant number of plastic bottles and aluminum foil bags are discarded, in addition to valuable waste such as treasure bottles and tin cans.

The aluminum foil bag (Tetra Lant bag), which can be lost after drinking, occupies more than 60% of all drinks in supermarkets and other stores.

Coupled with low prices, such as paper packaging, more people mistakenly believe that in line with environmental protection.

In fact, the aluminum foil cladding material is not just paper, but a layer of aluminum foil, two layers of paper, four layers of plastic, the seven layers of material to make them stick with a polymer agent.

It takes seven layers of packaging to make an aluminum foil package, so it's no wonder it doesn't leak.

According to statistics, a staggering 3 billion aluminum foil packets are thrown away in Taiwan every year.

The composite material of aluminum foil packages is a thousand years of garbage that is difficult to recycle and difficult to bury. Even incineration takes a lot of effort, wasting resources that aluminum foil and paper can recycle.

Even the manufacture of the patent country - Sweden, also can only be used to pack fresh milk, and Switzerland, Austria and two countries are explicitly banned the use of aluminum foil package.

However, looking at our citizens, they use 3 billion every year, no wonder garbage is always our nightmare in Taiwan.

It is necessary for consumers to review the garbage disposal and pollution problems caused by aluminum foil package as a composite material.

For your health, drink plain water. If you must drink soft drinks, make your own or buy large containers of recycled drinks.

In the comparison of less difference between iron cans and aluminum cans, although the activity of aluminum is larger than the general metal, but easy to form a layer of aluminum oxide protective layer and oxygen, and used in food containers, the inner layer will have a layer of plastic film.

The advantages of aluminum soda cans are that aluminum is odorless, nontoxic, light, tasteless, and a good conductor of heat.

Why are some drinks packaged in aluminum cans?

Some of them are tin cans?

What's the difference?

Take with tin cans, for comparison, because is more malleable than tin cans, qualitative light, and produce tin can cost less than aluminum cans, so when it comes to food, the food should be considered in addition to access and preservation methods to select, manufacturers will consider the cost problems between the material and food more, easy open cans cans of drinks, for example, the tin paste
