I. Starch meal box
Starchy lunch boxes are made of starchy materials, the most common of which are corn starch and cassava starch. This kind of meal box is environmentally friendly, safe, degradable and recyclable. It is suitable for microwave heating, but because of the fragile material, it often leaks or deforms.
II. Polyester lunch box
Polyester lunch boxes are made of polyester plastic, which can resist high temperature, have high transparency, and also have the characteristics of moisture-proof and oxidation-proof. However, polyester lunch boxes are generally non-degradable, although there are also a small number of degradable materials.
III. Cellulose meal box
Cellulose lunch boxes are usually made of natural materials such as wood fiber, which have certain mechanical strength and thermal insulation. This kind of lunch box can be recycled and degradable, but it should be noted that it needs to avoid high temperature or high humidity when using it, otherwise it is easy to deform.
IV. Biodegradable lunch boxes
Biodegradable lunch boxes refer to plastic materials that can be completely degraded by the natural environment. This kind of meal box is widely used in catering takeaway and other environments. The advantages are good heat resistance and ultraviolet stability, and it can be recycled, but its disadvantage is that the cost is higher than other types of lunch boxes.
Summary: Degradable lunch boxes have gradually become common items in people’s lives. Different types of lunch boxes have different characteristics and scopes of application. Choosing the right lunch boxes can not only contribute to environmental protection, but also ensure food safety and convenience.
