Where is the difference between body heat shrinkable film packaging machine and vacuum packaging mac
Vacuum packaging machine everyone not unfamiliar, this is a commonly used in all walks of life to the type of packaging machinery, after vacuum packaging products, not only can play a protective role of product, and prolong the shelf life of the food products, and vacuum packaging machine have a stick put oneself in the heat shrinkable film packaging machine, while also using vacuum packaging, but after the stick put oneself in heat shrinkable film packaging machine for packaging of products, from the appearance on the vacuum packing more than ordinary class, especially the packaging some lobster, lobster lifelike appearance, as if a visual feast, which can attract the attention of consumers, So what is the difference between the body heat shrinkable film packaging machine and vacuum packaging machine? Let's analyze it in detail.
First, the working principle is different
The working principle of close-fitting heat-shrinkable film packing machine and vacuum packing machine is different. Stick put oneself in the working principle of heat shrinkable film packaging machine is in a heated to melt the critical stick put oneself in the membrane when close to the product, and form a seal between the product environment, electronic control system to trigger the vacuum source release, stick put oneself in the membrane was instant quick vacuum stretching, stop heating heating system at the same time, stick put oneself in membrane against packaged products, cooling, finalize the design. The main role of ordinary vacuum packaging machine is to remove oxygen, the oxygen in the packaging bag and food cells, so that microorganisms lose the "living environment". Thus to achieve the effect of preventing food deterioration.
Two, the packaging appearance is different
A significant difference between the body heat shrinkable film packaging machine and vacuum packaging machine is that the packaging appearance is different. Ordinary vacuum packaging is bag, the product is put into the vacuum bag, and then vacuum, the effect is that the bag is attached to the product surface. And after stick put oneself in heat shrinkable film packaging machine for packaging of the product appearance is almost can't see the outer packing, this is because at the time of packaging products is a appear a higher degree of membrane, and this film is very thin, after packing, membrane fit tightly on the surface of the product, so if you don't watch carefully, is can't see the film, and after a stick put oneself in heat shrinkable film packaging machine products, stereo sense is stronger, from appearance to see alone than ordinary vacuum packaging machine to promote the grade of the product.
The ordinary vacuum packing machine is bonded together by sealing, while the close-fitting vacuum packing machine is ironed off by heating wire. The two-chamber vacuum packing machine has only one studio, and the body-fitting vacuum packing machine is divided into two vacuum chambers through the body-fitting film. The membrane is fitted through the pressure difference between the two vacuum chambers.
3. Different packing methods
Body shrinkable film packaging machine and vacuum packaging machine of different packaging methods. General vacuum packaging is the packaging bags commonly used, and generally, stick put oneself in heat shrinkable film packaging machine USES box or plate to in the food packaging, from packaging, stick put oneself in stick put oneself in heat shrinkable film packaging machine cost is higher than ordinary vacuum packaging machine, and stick put oneself in heat shrinkable film packaging machine for equipment processing technology, the more complex than ordinary vacuum packaging machine, so the equipment cost is higher than the general vacuum packaging machine, now stick put oneself in heat shrinkable film packaging machine is mainly for some seafood, steak with higher grade products for packaging.
To sum up, there are a lot of differences between close-fitting heat-shrinkable film packaging machine and vacuum packaging machine. When we pack different types of products, we should look at the product positioning and the product put on the market for the crowd to conduct a preliminary survey, and then choose the packaging equipment through this!
