In fact, the production of vacuum bags must follow a basic principle, that
is, their thickness should not be too thick, in the appearance of transparent
and opaque two kinds. Transparent means that the food inside can be seen from
the outside, while the food inside cannot be seen from the outside if it is not
transparent. Today, the editor will analyze the thickness of qualified vacuum
bags for you: the vacuum bag range is very wide. With the change of production
technology and materials, the problem of thickness gradually appears. The
thickness of vacuum bags produced by many manufacturers is too large to be
accepted by consumers when they enter the market.
Production should pay attention to the thickness of the suitable vacuum
bag, also is not too thick nor too thin, too thin is not packaging protective
effect, meet some tearing force could easily damaged, and if too thin the inside
of the packages have oil food, oily be soiled will through inside permeate
outside, this is to influence the quality of it. In addition, the vacuum bag
that is too thin is greatly affected by the environment. It is easy to decompose
under the sun exposure and rain immersion. Its thickness should be strictly
controlled.
Too thick vacuum bag also has many disadvantages, too thick is easy to
affect the shelf life of food, that is to say, it can shorten the storage time
of food, food has a shelf life, but this kind of vacuum bag will make the actual
shelf life and food quality does not meet. In addition, it is very harmful to
the environment. If it is discarded outside, it will not rot away after many
years, which is inconsistent with the proposal to advocate energy conservation
and environmental protection, and does not belong to the environmental
protection products supported.
In short, the thickness of the vacuum bag should not be too thick or too
thin. Only those with moderate thickness can be really used. People should
choose according to the actual needs when purchasing, do not blindly choose,
when purchasing to see its quality and design, and then in the choice, otherwise
it is self-defeating to choose less than they want the product is
outweighed.
