Are stainless steel lunch boxes and disposable lunch boxes good for food?
The stainless steel lunch box can prevent the dishes from deteriorating, and the disposable lunch box is suitable for the packaging of meals
The stainless steel lunch box is made of stainless steel fully automatic argon arc welding, which is made with precision. It is sanitary, non-toxic, durable, and has high internal and external brightness. It is used to contain food to achieve antibacterial and heat preservation effects. And it is sanitary, comfortable, convenient and more reassuring. It is applicable to office workers and students.
Disposable lunch boxes have been changed from foam lunch boxes to environmental protection lunch boxes. The original foam lunch boxes have been eliminated because they are not resistant to high temperature and the production process has caused damage to the environment. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes and so on have been taken away. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, simple production and low relative cost, so it has become the mainstream material for manufacturing disposable fast food boxes.
PP polypropylene, with mechanical and thermal properties, is suitable for packaging of meals. Dining boxes are divided into environmental friendly ones, mainly including plastic, paper, starch and rare metals.
