Reduce the quality accident of deoxidizer "leakage"

The deoxidizer can absorb the oxygen in the sealed container, inhibit the quality deterioration caused by oxygen, and achieve the effects of anti-mildew, anti-insect, anti-oxidation and color protection.

"Leaked powder" refers to the leakage of the contents of the deoxidizer during production or use

How to reduce the "powder leakage" phenomenon of the deoxidizer, especially the coil deoxidizer, has always been the focus of the industry.

This requires efforts in the selection of deoxidizer packaging materials, production mode, matching equipment selection, and use process

First of all, the deoxidizer packaging material should be "displaced perforated film".

Secondly, the production mode of deoxidizer is investigated and a better scheme is selected

Vertical machine: adopts the heat sealing mode of "heat sealing while cutting", the heat sealing area is mixed with dust, and the heat sealing is not strong enough to leak powder when the dust is long; Powder leakage caused by poor sealing; the "slicing" area is not completely consistent in size, and there are "long and short bags", which are easy to cut when used

Horizontal heat-sealing high-speed machine: adopt the heat-sealing mode of "heat-sealing first, then unloading", which eliminates powder leakage caused by "clamping"; the cutting and heat-sealing time is as long as 2-3 seconds, and the cutting time is sufficient , The heat sealing is firm, which can effectively avoid powder leakage caused by poor heat sealing; the "slice" area has the same interval size, and there is no "long and short package", which reduces the probability of powder leakage caused by wrong cutting

Blister machine: First, the ingredients of deoxidizer are punched into round sheets, and then packaged with a "blister machine" (a packaging equipment for making milk tablets and tablets)

Third, the selection of supporting "slicing" equipment also needs to be screened

At present, there are two types of roll deoxidizer layouts on the market: "cursor" (also called "electric eye") and "non-cursor"

There is also a slicing mode of the slicing machine, which is "on the material level".

In addition to the slitting mode, other performances of the slicer also need to be considered, such as: tape draw accuracy, paper film transfer synchronization, mis-cut alarm shutdown,

Finally, it is necessary to strengthen management during production and use to avoid artificial "powder leakage".

In summary, to effectively reduce the probability of "powder leakage" of deoxidizers, attention should be paid to product selection and use
