If you want to buy a lunch box and are health-conscious about cheap-quality plastic lunch boxes, Thervox's stainless steel lunch boxes are an excellent choice for you. Thervox sells lunch boxes and tiffin boxes for meals, made from high-grade steel such as 304 and 316, available in different sizes and suitable for every type of user — whether they are students, school-going kids, adults, office workers, travelers, or families who prepare all kinds of meals. In this guide, we look at why you should buy only Thervox lunch boxes instead of lunch boxes from other brands.
Which Tiffin Lunch Box Is Better: Stainless Steel or Plastic?
Durability and Lifespan
Tiffin boxes made from stainless steel are durable — they do not break when dropped and can last for years without cracking. Plastic lunch boxes, on the other hand, scratch quickly and can crack or even break under a little weight or when dropped, especially when used by young children.
Food Safety, Odor and Stains
When Pakistani families pack foods like biryani, spices, paratha curry, burgers, French fries, or oily meals in plastic lunch boxes, the plastic absorbs the smell of the food, and this odor does not go away even after washing. Stainless steel, on the other hand, does not absorb food odors, so no smell remains after cleaning. Steel tiffin boxes also do not stain after washing, while plastic containers often stain even after being cleaned.
Safe, Non-Toxic Food Storage
Food-grade stainless steel is BPA-free, which means it does not leach into meals when exposed to heat or acidic ingredients. Because of this, any kind of meal can be packed in it, and school-going kids' lunches remain completely safe. Plastic, on the other hand, is mostly not BPA-free, so meals packed in such plastic containers can be harmful to the health of both children and adults.
Rust and Corrosion Resistance
Quality stainless steel is treated to resist rust even with frequent washing, condensation, and exposure to salty or acidic foods common in Pakistani home cooking. This corrosion resistance keeps a lunch box looking and performing like new for years rather than months.
Heat Retention and Leak-Proof Design
Because of their gasket seal, stainless steel lunch boxes are leak-proof, and they can also keep food warm for longer since they retain heat well. Plastic lunch boxes, on the other hand, cannot hold heat for long, and the food inside cools down quickly.
Key Features of Thervox Lunchbox Containers
Thervox sells food-grade, high-quality lunchbox containers made only with 304 and 316 stainless steel, which places its lunchbox containers in the premium category. The key features of Thervox's lunch boxes are:
Durability and Material
We use high-quality material with a steel grade of 304 and 316, which makes the lunch box walls thick, protecting them from denting and allowing them to last for years.
Seals, Lids and Leak Protection
A reliable stainless steel lunch box uses a silicone gasket around the lid to create a tight seal that prevents curry, sauce, or dressing from leaking. This seal also helps keep food fresher for longer between packing in the morning and eating later in the day.
Lock and Clip Security
Metal or plastic clips lock Thervox lunch boxes tightly, so no matter what type of food is inside — whether it's liquid or something like ketchup — it does not leak into the bag. This especially protects school-going children's books and bags from getting spoiled.
Easy to Clean
Because they are made of stainless steel, our lunch boxes clean easily and do not let any food odor remain.
Multiple Compartment Options
Thervox's customers come from all walks of life, so our lunch boxes are designed with multiple compartment options, allowing users to buy according to their food portion needs.
Who Can Use Thervox Lunch Boxes?
Thervox sells lunch boxes for every person living in Pakistan — from a child going to school for the very first time to a person who goes to work and has lunch at the office. Our lunch boxes are also for children who go to madrassas to memorize the Quran and study for up to 12 hours, eating hot meals from our insulated lunch boxes, which are built to retain heat well. In short, Thervox sells lunch boxes for everyone.
How to Care for and Maintain a Tiffin Box
Although Thervox tiffin boxes are durable and resistant to many common stains and dents, using the right cleaning methods and storing the lunch box properly can help prevent discoloration, unpleasant odors, and damage to its components. Proper care and maintenance can help keep your stainless steel lunch box clean, hygienic, and in good condition for longer.
Wash the Lunch Box After Every Use
Clean your stainless steel lunch box after each meal to prevent food residue, grease, and odors from building up. Use warm water, mild dishwashing liquid, and a soft sponge to clean the inside and outside, then rinse thoroughly to remove any soap residue.
Avoid Abrasive Scrubbers
Many households in Pakistan use steel wool to clean utensils, but you should not regularly use steel wool, harsh scouring pads, or abrasive cleaning powders, as they leave scratches on the steel surface. Scratches may make the lunch box more difficult to clean and affect its appearance. A soft sponge or non-abrasive brush is usually a better choice.
Remove Stains and Food Residue
For stubborn stains, soak the lunch box in warm, soapy water for a few minutes before cleaning. A paste made from baking soda and a small amount of water may help with certain stains. Rinse thoroughly afterward and follow the Thervox care instructions.
Clean the Lid and Silicone Seal
If your lunch box has a silicone gasket, removable seal, or locking lid, clean these parts separately when possible. Food particles can collect around the seal and may cause odors or affect leak resistance. Therefore, do not reassemble the lunch box until all of its parts are thoroughly clean and dry.
Dry Thoroughly After Washing
Dry the lunch box with a clean towel or leave it open to air-dry. Avoid closing and storing it while moisture is trapped inside, as this can lead to unpleasant smells and may affect certain components of the lunch box over time.
Avoid Prolonged Contact with Certain Foods
If mostly acidic or salty foods are packed in the lunch box, it may affect the surface over time, particularly if the lunch box is not cleaned right after use.
Check Dishwasher Compatibility
Some stainless steel lunch boxes are dishwasher-safe, while others may have lids, painted finishes, insulation, or silicone components that require hand washing. So, if a lunch box is painted or has any kind of cartoon or character design on it, hand wash it instead, and use a soft cloth rather than steel wool.
