Food vacuum bag safety hazards and causes

Food vacuum bags have many advantages such as light weight, convenient transportation, chemical stability, and easy production. They are widely used in food packaging. By adding a certain amount of auxiliary polymer materials such as antioxidants and preservatives to the plastic, the food has a good protective effect. However, the surface of the plastic packaging is prone to food contamination due to frictional electrification and adsorption of fine dust impurities. Unpolymerized free monomers such as ethylene and ethylbenzene in the plastic packaging may increase the risk of migration to the food as the contact time prolongs, thereby causing food contamination. Stabilizers and plasticizers added to plastic packaging products are carcinogenic and teratogenic, and plastic packaging is used in large quantities to increase the recycling pressure and pollute the environment.

2, paper packaging and its harm

In recent years, paper packaging has been widely used in food packaging due to its advantages in various forms such as bags, boxes or cans, boxes, and the like. However, since most of the paper packaging raw materials are derived from the recycling of paper or paperboard, bacteria, chemical residues and some impurities are often attached to the produced paper packaging, increasing the risk of paper packaging contaminating food. In addition, most of the brighteners and fluorescent chemicals used in paper packaging are potential sources of food contamination.

3, glass containers and their harm

With the diversification and individualization of food vacuum bags, many glass containers made of silica are widely used in food packaging. In order to increase the gloss of glass containers, manufacturers often add arsenic. As a clarifying agent, hydrazine can even increase lead. In addition, glass containers of various colors are also used for containers for food packaging, in which foods are contaminated with substances such as silica which are easily eluted by glass.

On the other hand, more and more metals, ceramics, rubber monomers, etc. are applied as packaging or gasketing and sealing materials to food packaging, which may cause potential harm if not handled properly.

Food vacuum bag safety hazard reasons

The transportation and storage of food are inseparable from the application of various packaging materials, and the reasons for the packaging materials harming food mainly include the following aspects.

1. Production factors

The production enterprises of food packaging materials or containers are not strictly controlled in quality at the production stage. The raw materials used for production contain toxic and harmful waste materials. Some packaging materials used by enterprises are backward due to the application technology in production and printing, and quality management is not Problems such as regulation have buried hidden dangers of food safety.

2 use link factors

The use of food packaging materials is paying more and more attention to sensory effects. Enterprises are pursuing the shape of packaging materials or excessively pursuing practicality, while ignoring the safety functions and hygiene standards of food packaging materials, and the problems with people's methods of use, increasing foods. Security risk issues.

3 management link factors

In recent years, relevant departments have increased safety supervision in the field of food safety packaging, and a series of standards and rules have been introduced. However, the development of new materials and new raw materials has been introduced, and the phenomenon of lax supervision and lagging standards has existed to varying degrees, which has also increased food safety risks.
