Plastic Free Bento Box

Yes. The Plastic Free Bento is designed for reheating food in the microwave. Before microwaving, release the lid from its sealed position and place it loosely on top of the container. This allows the lid to cover the food without remaining sealed while heating. Reheat food for a maximum of 1 minute at a time at 1000W. Check and stir the contents between intervals, then continue reheating in 1-minute increments as required. Frozen food should be fully defrosted before microwaving.

Yes. The Plastic Free Bento contains zero plastic. It is made from 304-grade stainless steel, tempered glass and premium food-grade silicone. The Plastic Free Bento was developed as an alternative for people who want to store, carry and reheat their food without using plastic food containers. Smash's Zero Plastic Lunchware range was also recognised with an Australian Good Design Award.

The Plastic Free Bento is made using 304-grade stainless steel, tempered glass and food-grade silicone, with no plastic components. The stainless-steel base provides a durable food-contact surface, while the tempered-glass lid and silicone components create the pressure seal. The removable internal divider is also made from food-grade silicone.

Yes. The Plastic Free Bento is BPA-free and contains no plastic at all. The product uses food-grade 304 stainless steel, tempered glass and food-grade silicone. Smash food-storage products are tested to applicable food-contact and safety standards as part of our product compliance and manufacturing process.

The Plastic Free Bento is designed to resist spills when kept upright, but we don't recommend treating it as leakproof. The outer lid uses a pressure seal, while the internal compartments are not individually sealed. Low-viscosity liquids, oils and particularly liquid-heavy foods may leak through the outer seal. For best results, keep the Bento upright when carrying it and use it for solid or thicker foods rather than liquids.

The Plastic Free Bento can hold moist foods and thicker sauces, but it is not designed for carrying liquids or particularly runny foods. Low-viscosity liquids and oils have a greater chance of passing through the pressure seal, so we recommend keeping the Bento upright and carrying very liquid-heavy foods in a purpose-designed sealed container.

The Plastic Free Bento has a 1.3-litre capacity and is designed to hold a generous packed lunch. For example, it can accommodate: • A large sourdough sandwich with room for a piece of fruit when the insert is removed. • A wrap alongside cherry tomatoes, cut carrots and a small treat using the insert. • Around 200g of stir-fry, with the insert used separately for rice, vegetables or something sweet. The removable insert gives you flexibility to create separate sections or maximise the available space for larger foods.

Yes. All components of the Plastic Free Bento are dishwasher safe, including the stainless-steel base, tempered-glass lid and silicone components. This makes the Bento suitable for everyday use without needing to hand wash individual components.

The food-grade silicone components can be removed and washed in the dishwasher along with the rest of the Plastic Free Bento. Removing the components when cleaning also makes it easier to thoroughly clean the surfaces and edges where food residue can accumulate.

Yes, although we generally recommend the Plastic Free Bento for older children and adults. The Plastic Free Bento uses a pressure-seal lid that some younger children may find more difficult to open and close independently. For children under approximately 10 years old, our Classic Bento with clips or Bento Flex with multiple compartments may be easier to use.

The 1.3L Plastic Free Bento is a zero-plastic lunch box designed for a generously sized main meal, while the 1.8L Bento Flex provides more capacity and multiple compartments for an all-in-one packed lunch. The 1.3L Plastic Free Bento works particularly well when you're happy to carry some items separately - for example, packing your main lunch in the Bento and carrying a piece of fruit separately. The larger 1.8L Bento Flex is better suited to people who want to pack their sandwich or main meal, snacks, fruit and other items together in a single lunch box.

Yes. Hot food can be placed directly into the Plastic Free Bento. The food-contact surfaces are made from food-grade 304 stainless steel and food-grade silicone, so there's no need to wrap your food or place another material between the food and the container. As with any hot food container, take appropriate care when handling hot contents.

No. We don't recommend using the Plastic Free Bento in an oven or air fryer. The product has been designed and tested for its intended food-storage and microwave-reheating applications. It has not been tested for the higher temperatures or heating conditions associated with ovens and air fryers. For reheating, follow the microwave instructions provided with the product.

We do not recommend freezing the Plastic Free Bento. While customers may choose to do so, freezing is outside our recommended use of the product. For best results and to maintain the product as intended, use the Plastic Free Bento for storing, carrying and reheating non-frozen food.

Food-grade 304 stainless steel is commonly used for food-contact applications and provides a durable, non-reactive surface for storing food. The Plastic Free Bento uses a raw stainless-steel interior with no additional coating or lining applied to the food-contact surface. This differs from our Classic Bento, which features a ceramic lining, giving customers a choice between the two constructions.

The Plastic Free Bento uses 304-grade stainless steel. 304 stainless steel is a food-grade material widely used in food-storage and kitchen products because of its durability and suitability for repeated food contact.

The Plastic Free Bento has been specifically designed and tested for microwave reheating, despite its stainless-steel construction. When microwaving, release the lid from its sealed position and place it loosely on top of the container. Reheat for a maximum of 1 minute at a time at 1000W, checking and stirring the food between intervals. Frozen food should be fully defrosted before reheating.

Yes, but the lid must not be sealed or fixed in place while microwaving.| Release the lid and place it loosely on top of the container during reheating. Reheat for a maximum of 1 minute at a time at 1000W, checking and stirring the food between intervals.

Yes. The silicone components used in the Plastic Free Bento are food-grade and tested for food-contact use. The silicone allows the product to create its pressure seal and removable internal division without introducing plastic components into the product.

The Plastic Free Bento is a 1.3L zero-plastic lunch box made from 304-grade stainless steel, tempered glass and food-grade silicone. Unlike many traditional lunch boxes that use plastic for the container, lid or internal components, the Plastic Free Bento contains no plastic. All components are dishwasher safe, and the product has been designed for microwave reheating when the supplied instructions are followed. Smash's Zero Plastic Lunchware range has also been recognised with an Australian Good Design Award.
