While choosing lunch boxes, many people will consider the safety of the materials. In recent years, stainless steel lunch boxes have gradually become the first choice for many families and offices, especially after plastic lunch boxes have been gradually questioned for their safety. So, are stainless steel lunch boxes safer than plastic lunch boxes?
En tant que professional lunch box manufacturer, I will analyze the advantages and disadvantages of stainless steel and plastic lunch boxes in detail for you to help you make a wise choice.
Advantages of Stainless Steel Lunch Boxes
No harmful substances released
Stainless steel is a resistant metal that does not normally emit harmful substances into food.
On the other hand, most plastic lunch boxes can emit harmful chemicals like BPA and phthalates during use due to high temperatures or long-time use. These substances are linked to health problems such as endocrine disorders and cancer. Especially when heated, harmful substances are more likely to migrate into food in the case of plastic containers.
Forte durabilité
Stainless steel lunch boxes are much more durable than plastic lunch boxes. Even if used for a long time or washed, they are not easily damaged or deformed. Plastic lunch boxes may crack or deform due to high temperature, bumps or a long time, reducing their safety.
Antibacterial
Stainless steel itself has natural antibacterial properties, which can effectively prevent the growth of bacteria. However, if plastic is not cleaned thoroughly, it is easy to become a breeding ground for bacteria and mold, especially when there are scratches on the surface of the plastic lunch box, bacteria are easy to accumulate in it.
The Risks of Plastic Lunch Boxes
High Temperature Releases Harmful Substances
Plastic lunch boxes are easily deformed or release harmful substances under high temperatures, especially for low-quality plastic lunch boxes. In cases of holding hot food or under long-time high temperature, some harmful chemical substances, like BPA, may be released. Although it’s true that many plastic lunch boxes are advertised as “BPA-free,” there’s still some low-standard product existing in the market, which probably contains other similar harmful chemical substances that threaten human health.
May contain unknown chemicals
In order to enhance flexibility, some plastic containers may add various chemical additives, such as plasticizers, stabilizers, etc. These substances may affect the safety and quality of food when they are in contact with food for a long time.
Easy to absorb odor and pigment
Plastic lunch boxes easily absorb food odors and pigments. After long-term use, they may produce marks that are difficult to remove, affecting the original flavor and hygiene of the food.
Other Advantages of Stainless Steel Lunch Boxes
Facile à nettoyer
The surface of stainless steel is smooth and does not easily absorb oil and bacteria, making it very easy to clean. In contrast, the surface of plastic lunch boxes sometimes becomes difficult to clean due to scratches or stains, especially after long-term use, the plastic surface may become discolored or stained.
Environmentally friendly and recyclable
Because stainless steel is an eco-friendly recyclable material. Using stainless steel lunch boxes will help reduce plastic usage and decrease environmental pollution. Although plastic lunch boxes are at a state where they can be recycled, with their high frequency of use, they are usually thrown away without caring, which is contributing to an increase in plastic waste accumulation.
Conclusion: Stainless Steel Lunch Boxes Are Safer
On the whole, the stainless steel lunch box is far safer than a plastic lunch box, since it doesn’t have any harmful chemical composition, is long-lasting, anti-bacterial, and easy to clean, which meets modern family food safety requirements.
Although plastic lunch boxes may have their advantages in terms of portability and appearance design, if your first consideration is food safety and long-term health, then choosing a stainless steel lunch box is undoubtedly much wiser.
