What is the reason for the increase in bags for plastic corn processing?

1.For the reasons of the food itself, such as incomplete food sterilization, dry food is not fully dried, etc., in the environment of trace oxygen or high humidity, microorganisms multiply, which is easy to lead to mold, mildew, and bag expansion.

2.Substandard quality outer packaging can make oxygen or water vapor.

It enters the inside of the finished product packaging and promotes the reproduction of microorganisms, resulting in mold, mildew, and bag expansion of food. The quality problems that are prone to occur in packaging are generally concentrated in the following aspects:

1) Poor barrier - such as poor oxygen and water resistance of packaging materials, resulting in oxygen and water vapor slowly infiltrating into the packaging during long-term storage of finished products.

2) Poor sealing - such as poor sealing caused by poor sealing, resulting in outside air and moisture entering the packaging from the heat sealing part.

3) Physical and mechanical properties.

Inferior – such as poor toughness of packaging materials, resistance to puncture of contents, or production and storage processes.

Kneading or squeezing, so that the finished packaging in the process of storage and transportation on the packaging bag pinholes, creases or broken bags without timely detection, resulting in food contact with a large amount of oxygen, water vapor and mildew.

Extended information: There are many varieties of vacuum packaging machines, and the following factors should be considered when selecting.

a) Packing speed. In order to improve production efficiency, a vacuum packaging machine with two chambers or multiple chambers can be selected to improve the progress of the whole production.

b) Whether the packaged items need to be filled with other protective gases. A multi-functional vacuum packaging machine with an inflator is available.

c) The vacuum level of the packaged goods.

requirements. If the packaged items need to be stored well under high vacuum conditions, a cavity vacuum packaging machine needs to be selected.

d) Requirements for vacuum packaging machines for the composition status of packaged items.

When purchasing, aluminum alloy can be used for packaging solids, particles and other relatively dry and non-corrosive materials, and stainless steel can be used for packaging materials with soup and high salt and acid content.

or aluminum-magnesium alloy.

Seals. Silicone rubber is generally used.

Black rubber, a few low-grade products use foamed rubber, silicone rubber high temperature resistance, corrosion resistance, good sealing, long service life, foamed rubber poor sealing, easy to fall off, short service life.

This situation is likely to be caused by the high humidity of the corn, in this case, you must pay attention to it after drying, otherwise it is easy to have problems.

The reason for the processing of long belts of plastic corn may be that the material really looks similar.

The reason why Shuomi processed the bomb was that it was not sealed well and there was a leak.

It means that the fermentation is not complete, and after bagging, the fermentation will continue before the bag is expanded. If you want to solve the problem of bulging bags, there are two ways. The first is to continue fermentation until the fermentation is completed. The second is frozen packaging. At low temperatures, stop fermentation!

Food packaging is inedible after flatulence, the reason for flatulence is that when the food is spoiled, the carbon dioxide produced by bacteria multiply, and the vacuum-packed food, as long as it is flatulence, it has been damaged on the surface.

The reason for the bag expansion is very simple, it is very troublesome to solve, and mass production must have a sterile room, a high-temperature furnace, etc.

It is relatively simple to process a few bags at home: quickly put the freshly cooked corn or corn cob into a clean plastic bag and seal it, and at room temperature (25), the bag will not rise for 3 days. If you vacuum and then seal, boil in more than 80 water for another 30 minutes, and it will not deteriorate for 20 30 days at room temperature.

Theoretically: a spoonful of broth, in a sterile, vacuum (room temperature) state, will never spoil (swollen bag). Therefore, at room temperature, the length of time it takes to expand the bag depends on the number of bacteria in the plastic bag.

Summary. It is not edible.

After the food is spoiled, the microorganisms will decompose the organic matter in the food to produce gas, so it will reduce the volume of solids and increase the gas, forming the phenomenon of bulging outer packaging.

Because the food does not contain preservatives, microorganisms enter the food bag, decompose the organic matter in the food to produce gas, and there is a peculiar smell, this food has been rotted and can not be eaten.

Can you still eat bagged cooked corn when the bag is up.

It is not edible. After the food is spoiled, the microorganisms will decompose the organic matter in the food to produce gas, so it will reduce the volume of the solid slim body and increase the ignorant gas, forming the phenomenon of bulging the outer packaging. Because the food does not contain preservatives, microorganisms enter the food bag, decompose the organic matter in the dry air of the food to produce gas, and there is a peculiar smell, this food has been rotted and can not be eaten.

When I brought it in, it was cooked frozen corn on the cob, and it was in an ordinary bag, not vacuum packed, and I forgot to put it in the freezer, only in the refrigerator.

Within the expiration date, and there is no odor.

Can't you eat it too?

That's right. Thank you!

Try not to eat it. Good.

You are welcome.

Grain moisture is generally placed in a sunny place, not only to drive away moisture, but also to prevent insects.
