Injection molded plastic lunch boxes are a type of lunch box with good corrosion resistance. They are made by injection molding, which gives them high corrosion resistance. This means they will not be damaged by oil, sauces, or other food ingredients. This corrosion resistance allows food to retain its original taste and texture in the lunch box, ensuring that the food is fresh and delicious.
In addition to corrosion resistance, injection molded plastic lunch boxes also have high temperature and low temperature resistance. This means they can withstand high and low temperature environments and are suitable for refrigerating, freezing, and heating food. Whether it's refrigerating a lunch for a day or putting the lunch box in the microwave to heat it up, injection molded plastic lunch boxes can safely and effectively maintain the temperature of the food.
The corrosion resistance and temperature resistance of injection molded plastic lunch boxes are due to their manufacturing process and material selection. Injection molding is a common plastic processing technology that can inject molten plastic materials into a mold and solidify them by cooling. This process can produce lunch boxes with strong structure and good sealing, which can effectively prevent food ingredients from corroding the plastic.
The material selection of injection plastic lunch boxes is also a key factor. Generally speaking, plastic lunch boxes are usually made of food-grade polypropylene (PP) or polyethylene (PE). These materials have good corrosion resistance and temperature resistance, and will not release harmful substances to food and cause safety hazards.
In addition to corrosion resistance and temperature resistance, injection molded plastic lunch boxes also have other advantages. First, they are usually lighter than lunch boxes made of other materials, making them easy to carry. Second, injection molded plastic lunch boxes usually have good sealing performance, which can effectively prevent food from leaking. In addition, injection molded plastic lunch boxes have a longer service life and are not easily broken or deformed.
However, it should be noted that injection molded plastic lunch boxes also have some problems. First, some injection molded plastic lunch boxes may have the problem of plastic leachate release. It is necessary to choose food-grade materials and pay attention to correct use and maintenance. Second, since injection molded plastic lunch boxes are usually disposable, there may be environmental pollution problems. Therefore, we should advocate the use of recyclable injection molded plastic lunch boxes to reduce the impact on the environment.
