Compare Mepal Campus stainless steel and plastic bento boxes for kids. Learn material trade-offs and find the best fit for your child's lunch needs.
Quick answer
For most kids, a Mepal Campus plastic bento is lighter, more affordable, and easier for small hands to open. Choose stainless steel if you prioritize durability and avoiding plastic contact with food, but expect a higher price and heavier weight.
When choosing a lunchbox for your child, the material matters more than you might think. Mepal offers both stainless steel and plastic options in its Campus range, each with distinct benefits. This guide compares them based on practical factors like weight, durability, and ease of use.
We'll look at specific Mepal Campus products to help you decide which material suits your child's age, lunch habits, and your family's priorities.
Material differences at a glance
Stainless steel lunchboxes are known for their durability and resistance to odors and stains. They don't absorb food smells and are often preferred by parents who want to avoid plastic in direct contact with food. However, they tend to be heavier and more expensive than plastic alternatives.
Plastic lunchboxes, like many Mepal Campus models, are lightweight, affordable, and often feature fun designs that appeal to kids. They are also less likely to dent if dropped. The trade-off is that plastic may retain odors over time and some parents prefer to minimize plastic use for environmental or health reasons.
Weight and portability for small kids
Younger children, especially in preschool or early elementary, have to carry their lunchbox to and from school. A heavy stainless steel box can be a burden. Plastic lunchboxes are significantly lighter, making them easier for little ones to manage independently.
If your child walks or bikes to school, weight becomes even more critical. A lighter plastic box reduces strain on their back and makes it more likely they'll carry it properly. For older kids who don't mind the extra weight, stainless steel's durability can be a plus.
Durability and maintenance
Stainless steel is virtually unbreakable and resists dents and cracks better than plastic. It also doesn't stain from foods like tomato sauce or berries. However, it can dent if dropped on a hard surface, and it's not microwave-safe. Plastic Mepal boxes are microwave-safe (check the base), but they can crack if dropped repeatedly or exposed to extreme temperatures.
Cleaning is easy for both: they are dishwasher-safe. Stainless steel may show water spots if not dried promptly, while plastic can fade or become cloudy over time with high-heat washing. Consider how much maintenance you're willing to do.
Design and fun factor
Kids are often drawn to colorful, themed lunchboxes. Mepal's plastic Campus range features popular characters like Little Dutch, Barbie, and PAW Patrol, making lunchtime exciting. These designs are printed on the exterior and are resistant to wear.
Stainless steel lunchboxes typically have a sleek, minimalist look, which some older kids may prefer. But if your child loves a specific character, a plastic box with that design might encourage them to eat their lunch. There's a trade-off between aesthetics and material preference.
Trade-offs to consider
- Weight vs. durability: Plastic is lighter and easier for kids to carry, but stainless steel is more resistant to cracks and long-term wear. Choose plastic for younger kids, stainless for older ones who can handle the weight.
- Price vs. longevity: Plastic Mepal boxes are more affordable upfront, but stainless steel may last longer if not lost or dented. If budget is tight, plastic is cost-effective; if you want a long-term investment, consider steel.
- Design appeal vs. material preference: Plastic offers character-themed designs that excite kids, while stainless steel has a neutral look that some parents prefer for health reasons. Let your child's interests guide design, but weigh your comfort with plastic contact.
