What are the applications of plastic blow molding products in the food industry?
Blow molding products are widely used in the food industry. What are the applications of extrusion blow molding machines in the food industry?
Food, beverages, and glass bottles are permanent barrier containers and are not restricted by the 84 disinfectant and aseptic disinfectant. However, co-extrusion blow-molded multi-layer bottles are not easy to break, can be extruded, are light in weight, and have good barrier properties; and can freely design multi-layer structures with different capacities, specifications, and complex shapes, and the combination of layers The thickness and thickness can also be determined independently, making it an ideal food and beverage packaging product. It can be used as packaging for ketchup, rapeseed oil, jam, milk, orange juice, carbonated drinks, beer, etc.
Multi-layer co-extruded bottle products include three-layer combination, five-layer combination, and six-layer combination. There are more plastic bottles with six-layer combination of common materials. The three-layer bottle with EVOH or PA as the barrier layer has low moisture sensitivity and can be used for food packaging. The three-layer combination bottle of PE/PET/PC has transparency, high-efficiency barrier properties, excellent heat resistance and mechanical properties, and does not use adhesive materials, which has attracted widespread attention.
The main function of blow molding products used in the food industry is to ensure the preservation of various products, avoid food weight loss, loss of taste, and secondary pollution.
