What are the effects of unqualified food vacuum packaging bags? Which vacuum pump brands are suitable for food packaging machinery? Today, Xiaobian will take you a deeper understanding.
The substantial increase in the level of economic development has led to the continuous expansion of various domestic fast food and snack food markets. At present, vacuum packaging bags and food vacuum packaging machines are commonly used in the domestic food industry as food packaging bags and packaging equipment, and are not qualified. Vacuum packaging bags and vacuum pump packaging equipment will cause harm to human health. In order to be responsible to consumers, and also to occupy the food market, the quality of food vacuum packaging bags should be strictly controlled to ensure the quality of food packaging bags for food production. For the sales enterprise, the unqualified food vacuum packaging bag can not protect the food safety and hygiene, which is not conducive to the storage and transportation of food. At the same time, the unqualified food vacuum packaging bag will also have the color, fragrance and taste of the food. The impact is not conducive to the marketing of food. For ordinary consumers, unqualified food vacuum packaging bags can produce toxic substances that contaminate food and cause damage to the health of the consumer. Therefore, the harm of food vacuum packaging bags whose quality is not good is very large. In the production process, vacuum bag manufacturers should strictly control the quality and improve the quality of food vacuum packaging bags. In short, food vacuum packaging bags with unqualified quality are very unfavorable for food manufacturers and ordinary consumers. In order to be responsible for the vast number of consumers, and for the development of the company itself, the production of vacuum packaging bags should be strictly controlled. Quality control, improve the quality of food vacuum packaging bags.
At present, the vacuum pump equipment with good reputation is mainly Puxi vacuum pump and Laibao vacuum pump. The former has been involved in the vacuum packaging industry for many years, has a good reputation and a stable user base, while the Leybold vacuum pump is new. Dark horse, the momentum has been occupying the vacuum packaging market.
Various requirements in the production of food bags:
First, the requirements of the environment.
1. Before entering the food vacuum bag workshop, ask the workshop workers to change the overalls, change shoes, wash hands, and disinfect. If you are not a company employee who wants to visit, you have to wear a gown with a foot cover!
2. Before entering the food vacuum bag workshop, there is a device called “wind shower” which is used for disinfection. Everyone who enters the workshop must pass through here and disinfect it!
3, the overall hygiene requirements of the workshop clean, check every day, disinfect once a week! The ground is disinfected with 84, and the environment is disinfected with ultraviolet rays!
4: The workshop is required to be tightly sealed to prevent pests such as mosquitoes and mice from entering the workshop and polluting the environment!
Second, the requirements on the raw materials.
1. The food vacuum bag we produce, the PE raw material used is polyethylene resin. This raw material is non-toxic and tasteless, and is the best raw material for producing food vacuum bags.
2, food vacuum bag requirements is absolutely not added to the recycled material, because the recycled material is too dirty, and not pure PE material, there will be other harmful substances, so it is absolutely forbidden!
3, the production of food vacuum bags are not allowed to add "filling", "filling" is a kind of particulate-like substance added to save costs, is also harmful to the body, the way to distinguish is that the vacuum bag added will be whitish , the strength of the tensile strength and other aspects will be worse!
Three: Raw materials and finished products must have separate passages in and out of the workshop.
Food vacuum packaging bags are also called decompression packaging. What is ubiquitous in our lives is a symbol of the improvement of the quality of life, and the people who give it are more convenient.
Then the main definition of the food vacuum packaging bag is actually: refers to the gas in the bag, and then into the bag into the gas such as nitrogen, carbon dioxide. The main purpose of inputting nitrogen is because the nitrogen itself is actually an inert gas, which acts as a filling, so that the vacuum bag will maintain a positive pressure, so that the gas outside the vacuum bag will not enter the bag and can protect the food. And carbon dioxide is used to protect the food.
Food vacuum bags must have the conditions! Food vacuum bags are normal items for us, and they are used in life.
Then what are the conditions that a food vacuum bag must have! In order to ensure the safety of packaged foods, aromatic foods are required to have high aroma retention; fruit and vegetable fresh foods require packaging with high oxygen, carbon dioxide and water vapor permeability. In addition, the food packaging materials must have high tensile strength, tear resistance and impact strength. The oil and fat foods are required to have high oxygen barrier properties and oil resistance; dry foods are required to have high moisture resistance. Excellent chemical stability, no chemical reaction with foods to ensure food safety; in addition, high temperature resistance, to meet the requirements of high temperature sterilization and low temperature storage of food.
