What problems are prone to occur in frozen food packaging?

1.The impact resistance of the bag is poor, and it is easy to be damaged by external forces in the process of transportation, loading and unloading, and shelf placement, and it is very easy to break the bag and open the bag, which not only affects the appearance of the packaged product, but also cannot play the role of the packaging itself.

2.The smoothness of the packaging bag itself is not good, and the opening is poor in the production process, and the production efficiency is low, which will also reduce the utilization rate of the packaging bag and cause waste of cost.

3.The heat sealing strength of the packaging bag is not enough, and the heat sealing temperature is too high, resulting in the damage of the heat sealing layer, resulting in the reduction of the protective performance of the packaging bag, and the shelf life of the contents is greatly shortened, so that the contents can not reach the corresponding shelf life.

4.The peeling strength between the layers of the packaging bag is small, the tensile force is not enough, and the mechanical properties of the packaging bag are poor, resulting in the delamination of the packaging bag, the packaging bag can not achieve the due load-bearing effect, and the content can not play an effective protective role.

5.The cold resistance of frozen food can not meet the requirements, in the case of low temperature, can not maintain the original performance of the material, the packaging material is brittle, so that the mechanical strength of the packaging material decreases, resulting in the cracking and cracking of the packaging bag, and can not meet the protective effect of the contents.

6.The role of the easy-to-tear mouth of the packaging bag can not be effectively played, the tear strength is too large to cause the packaging bag is not easy to open, and the tear strength is too small to reduce the mechanical properties of the packaging bag, so it is necessary to meet the humanized design of the easy-to-tear mouth of the packaging bag, and at the same time to complete the protective effect of the product.

7.The puncture performance of the packaging bag, frozen food is generally hard after freezing, especially fish and meat products, containing bones and hard objects, and the product extrusion during transportation and stacking is easy to make the packaging bag pierced, so that the sealing of the packaging bag is damaged, so the puncture of the packaging bag is very high for frozen food.

I am a life answerer, Liu Xin, who is good at food! Traffic housekeeping! As well as clothes and jewelry!

Pre-packaged food includes frozen food, pre-packaged food: refers to food that is pre-packaged or prepared in packaging materials and containers. Frozen food is considered pre-packaged food, and the food circulating in the general market is pre-packaged food.

Traffic is empty and hail dry housekeeping! As well as clothes and jewelry! Pro-oh pre-packaged food including stool frozen food, pre-packaged food:

Refers to food that is pre-dosed or prepared in packaging materials and containers. Frozen food is considered pre-packaged food, and the food circulating in the general market is pre-packaged food.

<> pre-packaged food includes frozen food, can you sell packaged beef and mutton slices?

Dear, you're getting the best of luck. If the food circulation license contains pre-packaged food, including frozen and refrigerated food, it can be sold raw meat, I hope it can help you, thank you, I wish you a happy life and prosperous business.

1. One is vacuum packaging;

2. Second, after vacuum packaging, it will be stored in a foam box, which is filled with ice cubes, and the holes outside the vacuum packaging should be filled with ice cubes;

3. The third is to seal the foam box and send it to the cold storage to be stored until it is to be delivered.

4. It is best to use professional fresh food express for fresh products: for example: I love ice cream express and black cat express.

However, the delivery area is limited to land and file. Because of the characteristics of fresh food itself, express delivery is indeed very difficult, it depends on the distribution area, at present in the developed areas are more reliable, if you are not very developed in the place, to analyze your type of frozen food, and choose different types of express delivery.

5. Ordinary express delivery: If it is quick-frozen cold food, it can be stored at about 0 degrees in the morning, such as salmon, put some ice cubes when the quick-frozen food is expressed, as long as the express delivery is delivered, the ice cubes can not melt, so according to the cold and fresh food, you can choose ordinary express delivery according to the arrival time of the express.

6. Professional fresh product express: frozen food such as ice cream, imported meat food, rice and flour products, etc., the best storage conditions are minus 18 degrees, ice cream at minus 12 degrees, such as tuna needs to be stored at minus 60 degrees, and the temperature of the ice cubes is only about 0 degrees, so the use of ice cubes to preserve frozen food is not good, and such express delivery for your customers to refuse, express delivery to the home is not at home can maintain the quality of your quick-frozen food.

Need. Vacuum oxygen removal can inhibit the growth and reproduction of most microorganisms (such as molds and yeasts), but it cannot inhibit the multiplication of anaerobic bacteria, so it also needs to be refrigerated or frozen to inhibit anaerobic bacteria at low temperatures.

Vacuum packaging is not a substitute for refrigerated or frozen preservation, and any perishable food that requires refrigeration must still be refrigerated or frozen after vacuum packaging. Moreover, the vacuum freshness period of ingredients stored at different temperatures is different.

No, freezing is to keep fresh, the principle is that the activity of bacteria is very low at low temperature, so the food is not easy to spoil, vacuum packaging isolates the air, there will be no bacterial contact, so it can also be kept for a long time,

No, it can be stored at room temperature.

Summary. Hello, vacuum-packed food still needs to be frozen!

In fact, vacuum-packed food is not completely safe. The safety of vacuum packaging is affected by a variety of conditions, and any unqualified link will affect the safety of food. Food still needs to be sterilized after vacuum packaging, and perishable food must be refrigerated after vacuum packaging.

Recently, the Anhui Provincial Consumer Protection Committee issued a consumer reminder that any perishable, food that needs to be refrigerated or frozen after vacuum packaging, vacuum packaging is not an alternative to refrigeration or freezing preservation, vacuum packaging is to extract the air in the completely sealed packaging bag, and complete the sealing process after reaching the predetermined vacuum degree, so that the items in the bag can be stored in a vacuum environment for a long time.

Whether vacuum-packed food products need to be frozen.

Hello, vacuum-packed food still needs to be frozen! In fact, Zhenheng leaked empty packaged food is not absolutely safe. The safety of vacuum packaging is affected by a variety of conditions, and any unqualified link will affect the safety of food.

Food still needs to be sterilized after vacuum packaging, and perishable food must be refrigerated after vacuum packaging. Recently, the Anhui Provincial Consumer Protection Commission issued a consumer reminder, any perishable, need to refrigerate food in vacuum packaging must still be refrigerated or frozen, vacuum packaging is not an alternative way of refrigeration or frozen preservation, vacuum packaging is to completely enclosed the air in the bag to extract away, after reaching the predetermined vacuum degree to complete the sealing and disturbing process, so that the items in the bag in the vacuum environment for long-term storage.

I hope mine can help you.
