Perfect inflatable packaging technology system and the use of efficient packaging machinery are also important conditions for the wide application of inflatable packaging. The application of vacuum unit in vacuum inflatable packaging meets the requirements of inflatable packaging. Inflatable packaging is a kind of packaging method that packs products into airtight packaging containers, vacuums (or not), then fills protective gases (generally N2, CO2), and then seals them. In short, it is a packaging method that removes oxygen from the packaging system by degassing or aerating technology, improves the atmosphere around the products in the packaging, prevents or weakens the chemical or biochemical reactions of the products, and thus achieves the purpose of protecting the products.
The principle of vacuum inflatable packaging is to put the package under the heating rod and put the air nozzle into the bag turn on the switch step on the foot switch slide the heating rod under the action of the cylinder to the sponge bar to press the bag mouth to stop vacuum inflatable air nozzle to retreat under the action of the cylinder. The heating rod continues to slide down to heat, seal and cool. _Finished product_Heating rod reset. Vacuum extraction can be completed by vacuum unit.
1. Eliminating part of the air (oxygen) in the packaging container can effectively prevent food spoilage.
2. The use of good barrier (air tightness) packaging materials and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid food weight loss, odor loss and secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat transfer. This can improve the efficiency of heat sterilization and avoid the cracking of the packaging container due to the expansion of the gas when heating sterilization.
In the food industry, vacuum packaging is widely used. Various kinds of cooked products such as chicken leg, ham, sausage, roast fish fillet, beef jerky, etc. and pickled products such as various pickles, bean products, preserved fruits and other foods that need to be kept fresh are increasingly using vacuum packaging. Vacuum packaged food has a long shelf life, which greatly prolongs the shelf life of food.
At the same time, the use value of the vacuum unit for inflatable packaging is as follows:
1. Cost savings: You can save a lot of money on similar products.
2. tailor-made: tailor-made for you according to the specifications of the goods, making the protection more perfect.
3. Increase the speed: the one-way check valve inflates or deflates more quickly when packing.
4. Cargo safety: fully fill the gap between cargo, support the weight of cargo caused by shaking, absorb vibration, protect cargo from damage in transportation.
5. Environmental protection and energy saving: With proper use, this product can be reused, that is, environmental protection and save your cost.
6. Fast Customs Pass: Save the company’s transportation and storage costs.
