There are a lot of customers in the use of food packaging, always reflect the vacuum bag is damaged, why our technicians, please?
In addition to edit before summary, some of the products will have edges and corners, which is the thickness of the vacuum bag is not enough, we will use stronger because the vacuum degree, so going on, if the bag is not thick, can cause damage, so for the vacuum packaging machine
, we still require the use of vacuum bag up to standard thickness, to ensure normal work of vacuum.
So how to choose the material of packaging?
Today, the editor brief introduction:
in order to maintain or to keep the atmosphere of the packaging container, food vacuum packaging puts forward different requirements on packaging materials.
Permeability and moisture permeability of plastic packaging materials by the molecular structure of polymer, film thickness, the influence of factors such as temperature and humidity changes.
After vacuum or inflatable packaging under the influence of atmospheric environment, packaging container or mixed gas of oxygen concentration in the concentration of each component in the change.
The choosing principle of packaging materials is to reduce the influence of the atmospheric environment, get the longest shelf life.
based on the characteristics of food preservation, used in vacuum and air permeability of packaging material requirements can be divided into two kinds: one kind is high barrier packaging materials, vacuum and inflatable packaging for food preservation, in order to reduce the oxygen content in the container and the change of the concentration of mixed gas composition;
The other is a breathable packaging materials, used to keep the fresh fruits and vegetables in lower respiratory rate when pneumatic vacuum packaging machine
Vacuum packing and air moisture permeability of packaging materials have the same requirement.
Resistance to water vapor, the better, the more conducive to the preservation of food.
vacuum packaging machine packaging information must have a high barrier property.
Food vacuum packaging machine out of air inside the bag, to the expected after vacuum sealing process.
Is used widely in food industry, vacuum packaging, all kinds of cooked products, such as chicken, ham, sausages, grilled fillet, beef jerky, etc;
Pickled products such as all kinds of pickled vegetables and soy products, dried fruit, etc are used more and more various need fresh food vacuum packaging.
After vacuum packaging of food freshness long, greatly extend the shelf life of food.
Greasy food requirements of high oxygen resistance and oil resistance;
Dry food are high moisture resistant, to ensure the smooth circulation of packaged food.
The fragrance of sweet food needs highly preserved;
Fruits and vegetables fresh food need high oxygen, carbon dioxide and water vapour permeability.
In addition, food packaging materials should also have high tensile strength, tearing strength, impact strength, good chemical stability, not any chemical reaction with food inside, in order to ensure food safety;
In addition, it also should has high temperature resistance, in order to meet the requirements of food of high temperature and low temperature disinfection storage.
as a result, for vacuum packaging machine, we should also pay attention to the choice of packaging, to ensure that we can normal vacuum, seal, and finish the packing work.
A kind of heat pumping air into vacuum state, sealing, cooling the one-time completed function, apply to food, aquatic products, chemical raw materials, electronic components, precision parts and other products of vacuum sealing, can prevent oxidation, mildew, corrosion, moisture, but also extend the product with good quality fresh storage life of the machine.
Recommended products are DZ600 today / 2 l single chamber vacuum packaging machine, belong to custom vacuum packaging machine.
Seal line length is 600 mm, can be used for both objects forming packaging, can also be used for packaging large objects.
The whole machine adopts 304 stainless steel liquid crystal panel, equipped with two sets of vacuum pump, can be used to improve the studio or concave surface.
Is the most popular single chamber vacuum packaging machines.
Applicable industries: food,
Meat products, bean products, pickles, etc. One, low moisture food)
