In food, it is stored, among which, among them, to obtain barrier. Here, let’s talk here. Sealing. Essence
The so -called sealing, so -called preventing material or loading. During the production and production process of food packaging bags, because the links are relatively micro -hole and micropores, the connected small hole strength is thin because the links are relatively compared.都都会会对对食品食品食品食品食品产生产生很的的影响影响影响影响，直接的影响影响影响直接直接直接直接直接直接影响产品的的孔孔孔孔小包装袋保鲜的。
Pre -performance, in advance and testing, strengthen it, strengthen the test and detection, test in time, and timely detect and detect and detect and find out in time to find defects and defects in a timely manner. Essence Essence Essence Packaging bag in a packaging bag. However, when the solid is solid, how to leak the food, food, food, food, food, food, food, food bags?
Water (vacuum method)
Usually, there is a test device for the air.
Test device
According to GB/T15171-94 Packing machine "Sealing Performance Method" requirements
1.: It is composed of a sealing cover that can withstand stress pressure. Essence Vacuum container containers are used to put on test liquid liquid and test samples;;; sealing can ensure the closure of the vacuum chamber.
2. Sample: Used to fix the liquid liquid, its liquid liquid liquid liquid liquid liquid liquid liquid liquid and shape shape cannot be shaped and shape, observation, observation, observation, observation, observation, observation, observation, observation, observation and observation
3: Including the connection pipe, the empty source and the same exhaust pipe. All should be equipped with open and closing control, opening and closing, opening and closing, opening and closing
4. True: Used to measure the internal vacuum, short, short Automatic packing machine degree
5, device: including taking the short switch and adjusting the device. Essence
Third, color printing factory test
In the middle, device of the medium vacuum vacuum principle. The generator generator uses the rational flow-flowing principle C-95 seal (vacuum generator) as the example example example example example examples, which
1. A moderate amount of tap in the vacuum, pocket water and water sample bag. Essence Essence
2. The vacuum chamber seal the lid, its connected fixture water, turn on, turn on the switch, rotate the switch, rotate, rotate the rotation adjustment knob
Determine the characteristics of the real vacuum value test sample (such as use, etc.
3. During the situation of pumping and keeping leakage leakage leakage, the five conditions of the five Pillow type packing machine conditions are produced by continuous and continuous bubbles. Single isolated isolated, isolated and isolated bubble bubble bubbles may be
4, real knob, open, make the atmosphere, open, open, remove. ,take out
If the samples are not produced and inspected during the maintenance period, there is no water, then
The method of use is required to be outside the test, or the test conditions conditions and conditions, or the leakage, or liquid, or resume restoration to restore the indoor indoor pressure pressure pressure pressure of indoor indoor indoor indoor indoor
Precautions during testing
1. Make sure to observe during the period
2. The permeability test can be certain.
3. You can use the packaging bag detection, detection, detection and detection and detection of the color printing factory. It is also used for packaging bags and packaging bags into interior. Whether sealing is qualified.
