Airtight Seal & Freezer Safe Reusable Food Storage

Take a big step towards a plastic free kitchen with MasterClass’s reusable silicone food bags. They work much like the typical sandwich bags you buy from supermarkets, but with one important difference - they’re washable, resealable, and reusable many times. Use them to freeze leftovers that would otherwise end up in the bin, or as meal prep bags to organise a full week’s worth of dishes - their translucent design means you can always see what’s inside. They make excellent reusable sandwich bags too. You can seal up your snacks, then heat them directly in the microwave when you get to work or school. The bags are made of thick, flexible, LFGB grade silicone, and have a robust sliding seal mechanism that creates an airtight, leakproof lock - ideal for carrying in your bag, or eliminating spillages in the fridge or freezer. This listing is for a single 1.5 litre reusable sandwich bag.

This robust, leakproof mechanism keeps food fresh without relying on fiddly press seals or fragile zippers. Instead, it uses a simple slider to create an airtight lock. It can be opened and resealed many times over, without breaking or wearing away. The slider glides on and off easily, yet is totally leakproof, so your food won’t spill in your freezer or bag.

Keep your lunch fresh and cool all day long with this insulated lunch bag. A food-safe, BPA-free PEVA lining ensures chilled goods are kept cool for a minimum of two hours and hot foods stay warmer for longer, too! Spills are contained within the bag, thanks to the smart leak-proof lining, while the shower-resistant polyester exterior stops water from getting inside and ruining your lunch. TIP: Add a couple of ice packs inside the cooler bag when in use for extra coolness! Check out BUILT’s range of lunch wraps, bottles, food jars and ice packs to upgrade your meals on-the-go.

Hate food waste? So do the folks at MasterClass. That's why they created these clever reusable freezer bags. Made of strong, flexible plastic, they're perfect for cutting down on waste and organising your culinary life. You can use them for all sorts of storage jobs. Freeze leftovers to reheat later. Prepare tasty, healthy meals in advance. Seal up sandwiches for low-cost workday lunches. Then use them again and again, thanks to their robust and dishwasher safe design. Best of all, when they do eventually wear out, they can be recycled with carrier bags at many local supermarkets. Take that, single-use plastics! These plastic sandwich bags feature innovative nano-microporous vents that let food breathe. These tiny holes let food breathe and control moisture for long-lasting freshness, while also preventing nasty bacteria from getting inside. Each bag features an easy-close locking seal too, which is leak-proof to avoid messy spills. The translucent plastic design means it's easy to see what's inside (so no more mistaking last night's curry for tomorrow's casserole). Explore the MasterClass collection to discover more eco-savvy food storage solutions, including Eco-Snap containers made of Eastman Tritan copolyester. You get 20 in the set.
