Static electricity is undoubtedly an invisible killer for the enterprises using plastic flexible packaging. Some plastic bags bring static electricity in the process of use (Gu ò ch é ng), so how can plastic packaging bags and food packaging bags prevent static electricity?

The phenomena of solid charge and gas discharge in the process of printing and post-processing are called electrostatic theory;. Food packaging bag refers to the film container directly contacting with food and used for clothing and food protection. Its English name is food packaging pouch. Food packaging bag should be produced with food grade plastic film, generally more than two layers of composite material packaging bag. The food stored in the packaging bag needs to avoid extrusion, impact, shock, temperature difference and other phenomena. The outer shell of food packaging bag can separate food from oxygen, water vapor and stain. Anti leakage is also a necessary factor in packaging design. Some packages contain desiccants or deoxidizers to extend shelf life. Vacuum packaging or removing air from packaging bags is also a major food packaging method. Keeping food clean, fresh and safe within the shelf life is the primary function of the packaging bag.

The emergence of static electricity brings unexpected harm and inconvenience to the process of using plastic packaging bags, whether it is using, grounding, ion neutralization, environmental relative humidity, or electric eliminator, or adding in substrate and printing auxiliary materials, etc; Its fundamental purpose is to reduce the resistivity of the surface layer of the bulk resistance polymer packaging material to below 1010 Ω, so as to reduce the accumulation of static electricity in the plastic flexible packaging molding process, so as to promote the innovation of packaging technology. The outer shell of food packaging bag can separate food from oxygen, water vapor and stain. Anti leakage is also a necessary factor in packaging design. Some packages contain desiccants or deoxidizers to extend shelf life. Vacuum packaging or removing air from packaging bags is also a major food packaging method. Keeping food clean, fresh and safe within the shelf life is the primary function of the packaging bag. Plastic bags are essential items in people's daily life, and are often used to hold other items. It is widely used because of its cheap, light weight, large capacity and easy to store, but it is forbidden to produce and use because of its long degradation cycle and difficult handling problems. Printing material is the main carrier of commodity packaging, printing material is the main means of decorating packaging and disseminating new commodity number. In the future processing, effective measures to improve, make up and perfect (complete) the quality of commodity packaging (point to the solution to the problem) are brought about by printing material, printing material and post-processing. We all know that plastic flexible packaging or food packaging bags are made of two layers of multi-layer plastic film (thin and soft transparent sheet). The printing material mentioned above refers to the plastic film used for the substrate of printing and packaging; the printing material includes oil ink, adhesive, thinner, etc.; the post-processing includes (B ā o ā o) Ku ò) glazing, peritoneum, heat sealing, cutting, bag making, etc. In general polymer (high polymer) plastic molding composite, heat sealing and printing, static electricity will cause adverse processing consequences, so in daily production, how to eliminate the static electricity in plastic packaging bags? 1. Environmental relative humidity method: for example, in the work environment, the humidity in the air is relatively increased, and water can be sprayed in the air. 2. In order to transfer out the static electricity, we should install the device of corona discharge or eliminator or radioisotope surge apparatus on the printing or laminating machine of plastic bags. 3. In this paper, we introduce some organic antistatic agents into the system of plastics, substrate, printing ink, varnish, adhesive, etc. This is the simplest way to eliminate static electricity. It is necessary for safe production to eliminate the static electricity of plastic and food packaging bags.
