There are many differences between sealed bags and vacuum bags.
First of all, they are made of different materials: sealed bags are usually made of tumbling plastic or polyethylene materials, while vacuum bags are usually made of polyethylene, vinyl vinyl alcohol (EVA), or polyester fibers.
Secondly, they are used for different purposes: dense messy sealed bags can be used to preserve food, medicines, clothes, etc., to prevent moisture, while vacuum bags can be used to preserve food, clothes, etc., and are large to prevent rot or deterioration.
Finally, they are also sealed differently: the sealed bag can be sealed with hot melt adhesive, while the vacuum bag can be sealed with a vacuum machine.

Sealed bags work better than vacuum bags.
The sealed bag can be used instead of the vacuum bag, and the sealed bag is also very good, which can prevent moisture from entering the socks.
Sealed bags can be used for the inner and outer packaging of various small items (jewelry, small hardware, toys). The sealed bag produced with food-grade raw materials can store all kinds of small food, tea, seafood, etc., moisture-proof, anti-cross-smell, anti-water, anti-insects, and prevent things from scattering; Sealed bags can also be used for the packaging of clothing and other everyday items, and are used in a wide range of applications. The sealed bag can be produced by adding anti-static masterbatch during film blowing production, which is generally used in the electronics industry.

The vacuum packaging machine is to pump the inside of the packaging bag into a low vacuum, and then automatically seal it immediately. Due to the high vacuum degree in the bag, there is very little residual air, which can inhibit the growth of microorganisms such as bacteria. For some fluffy items, the volume can be reduced after vacuum packaging.
In this way, the packaged items can achieve the characteristics of "four prevention, two provinces, and one quality": that is, moisture-proof, mildew-proof, pollution-proof, anti-oxidation, volume-saving, freight-saving, and prolonged storage period.
The vacuum packaging machine is suitable for all kinds of plastic composite film bags or aluminum foil composite film bags, such as polyester polyethylene, nylon polyethylene, polypropylene polyethylene, polyester aluminum foil polyethylene, nylon aluminum foil polyethylene and other composite materials, for a variety of raw and cooked food, fruits, native products, medicinal materials, chemicals, precision instruments, clothing, hardware products, electronic components, military products and other solid, powdery objects, liquid, solid-liquid mixtures for vacuum packaging.
In the food industry, vacuum-packed food is very common, and various cooked products such as: chicken legs, ham, sausages, etc.; Pickled products such as various pickles, various soy products, preserved fruits and other kinds of food that need to be kept fresh are increasingly using vacuum packaging, and the food that has been vacuum packaged has a long shelf life, which greatly extends the shelf life of food.

Cylindrical roller bearings Luoyang Longma Bearing **** There are many types of cylindrical roller bearings, which are distinguished by structure, including N, NF, NJ, NU, NUP, NCL, RN and RNU types. In terms of load capacity, there are ordinary and reinforced cylindrical roller bearings. The dimensions of the reinforced cylindrical roller bearing are the same as those of the ordinary type, but the diameter, length and number of rollers have increased, so the load bearing capacity has increased. >>>More
When the air passes through the material layer in the state of random filling of solid particles from bottom to top, and the air velocity reaches or exceeds the critical fluidization velocity of the particles, the particles in the material layer are churning up and down, and some particles are entrained by the air flow and the state of the material layer is called the fluidized bed. >>>More
