Picture this: You’ve cooked a delicious meal, and now your refrigerator is a Tetris game of leftovers. Containers of all shapes and sizes are battling for space, threatening to topple over every time you open the door. Sound familiar? In the modern kitchen, plastic food tubs have become indispensable tools, storing everything from tonight’s dinner to tomorrow’s lunch. They offer convenience and organization, but understanding how to choose the right tubs, use them safely, and care for them properly is crucial for both your food and the environment. This guide provides a comprehensive overview to help you navigate the world of plastic food tubs and make the most of these kitchen staples.
Types of Plastic Food Tubs
The realm of plastic food tubs is vast and varied. They’re not all created equal. Different types of plastics offer distinct advantages and disadvantages, and understanding these differences will empower you to make informed purchasing decisions.
By Material
Polypropylene (PP): Polypropylene is a workhorse plastic. Often easily identifiable by the number five recycling symbol, it is known for its durability and heat resistance. Plastic food tubs made from polypropylene are generally considered microwave-safe, making them perfect for reheating leftovers directly from the refrigerator. Polypropylene can withstand higher temperatures without warping or leaching harmful chemicals. This is a huge plus. However, polypropylene isn’t always the most visually appealing. It can sometimes lack the clarity of other plastics. Some users have also reported it being more prone to staining with certain foods, such as tomato-based sauces.
Polyethylene (PE): Polyethylene is another commonly used plastic in the production of plastic food tubs. This plastic is characterized by its flexibility and lightweight nature. It is generally more affordable than other plastics. Because of its flexible nature, polyethylene is a great material for making lids. However, it’s important to note that polyethylene often isn’t as heat-resistant as polypropylene. Many polyethylene plastic food tubs aren’t suitable for microwave use.
Tritan: Tritan has emerged as a popular alternative in recent years, especially for those concerned about BPA. Tritan plastic food tubs are BPA-free, shatter-resistant, and boast exceptional clarity, rivaling that of glass. This material maintains its transparent look even after repeated use and washing. Tritan is also relatively resistant to staining and odors. However, Tritan is generally more expensive than polypropylene or polyethylene. Although durable, it can scratch more easily than some other plastics.
Other Plastics: While polypropylene, polyethylene, and tritan are the most common, other plastics may be used in specialty plastic food tubs. These might include polystyrene (often used in single-use takeout containers, but not recommended for long-term food storage due to potential chemical leaching) or high-density polyethylene (HDPE), which offers enhanced strength and chemical resistance.
By Design and Function
Basic Round or Square Tubs: These are the classic, all-purpose plastic food tubs you’ll find in most households. They are typically used for storing leftovers, packing lunches, or keeping pantry items fresh. Their simplicity makes them affordable and easy to clean, but they may not be the most space-efficient option, and often lack specialized features.
Divided Containers: These plastic food tubs are a game-changer for meal prepping and portion control. They feature separate compartments, allowing you to keep different food items separate and prevent them from mixing. These are perfect for packing balanced lunches or preparing meals ahead of time.
Stackable or Nesting Tubs: Space is often a precious commodity in kitchens. Stackable or nesting plastic food tubs are designed to maximize storage efficiency. When not in use, they can be stacked neatly inside each other, saving valuable cabinet space.
Leak-Proof Containers: Anyone who’s experienced a leaky food container in their bag knows the importance of a leak-proof design. These plastic food tubs feature airtight seals that prevent spills and leaks, making them ideal for storing soups, sauces, dressings, and other liquids.
Specialty Tubs: Beyond the basics, there’s a wide array of specialty plastic food tubs designed for specific purposes. These can include deli containers (for storing cold cuts and salads), ice cream tubs (designed to prevent freezer burn), and even containers with built-in measuring cups or graters.
Choosing the Right Plastic Food Tubs
Selecting the best plastic food tubs for your needs involves considering a few key factors. Asking the right questions will save you money, space, and peace of mind in the long run.
Consider Your Needs
Frequency of Use: If you plan to use your plastic food tubs daily, investing in durable, high-quality options is a smart move. If you only need them occasionally, more affordable options might suffice.
Types of Food You Store: Different foods have different storage requirements. If you frequently store oily or acidic foods, choose plastic food tubs that are stain-resistant and won’t react with the food.
Space Constraints: Assess your storage space. Stackable or nesting tubs are essential if you have limited cabinet space. Also, consider if you want to be able to store your tubs in the freezer.
Key Features to Look For
BPA-Free Certification: BPA (Bisphenol A) is a chemical that has been linked to potential health concerns. Always choose plastic food tubs that are clearly labeled as BPA-free. This ensures that the plastic won’t leach harmful chemicals into your food.
Microwave and Dishwasher Safe: For maximum convenience, opt for plastic food tubs that are both microwave and dishwasher safe. This will save you time and effort in both reheating and cleaning. Always check the manufacturer’s instructions to confirm safe usage.
Leak-Proof Design: If you plan to store liquids, a leak-proof seal is a must-have feature. Look for plastic food tubs with tight-fitting lids and silicone gaskets that prevent spills and leaks.
Durability: The durability of a plastic food tub will determine how long it lasts. Look for sturdy plastics that can withstand repeated use and washing without cracking or warping.
Clear vs. Opaque: Clear plastic food tubs allow you to easily see the contents without having to open them. Opaque tubs can protect food from light, which can help preserve its freshness.
Budget Considerations: The price of plastic food tubs can vary widely depending on the material, features, and brand. Set a budget before you start shopping and prioritize the features that are most important to you. Remember that investing in higher-quality tubs can save you money in the long run by reducing the need for frequent replacements.
Safe Usage of Plastic Food Tubs
Even the best plastic food tubs can pose risks if not used properly. Following these food safety guidelines will ensure that your food stays fresh and safe to eat.
Food Safety Guidelines
Proper Food Cooling: Always cool food completely before storing it in plastic food tubs. Hot food can create condensation inside the container, which can promote bacterial growth.
Avoiding Overfilling: Overfilling plastic food tubs can prevent the lids from sealing properly, increasing the risk of spills and contamination.
Understanding Food Storage Timelines: Familiarize yourself with recommended food storage timelines. Even in airtight containers, food will eventually spoil.
Microwave Safety
Checking for Microwave-Safe Symbols: Before microwaving food in plastic food tubs, always check for the microwave-safe symbol (usually a picture of a microwave). Not all plastics are microwave-safe.
Proper Venting Techniques: Vent the lid of the plastic food tub slightly before microwaving to allow steam to escape. This will prevent pressure from building up inside the container.
Avoiding Prolonged Heating of Fatty Foods: Fatty foods can reach extremely high temperatures in the microwave, which can cause some plastics to melt or leach chemicals.
Freezing Food
Choosing Freezer-Safe Tubs: Not all plastic food tubs are suitable for freezing. Look for tubs that are specifically designed for freezer use. These tubs are typically made from more durable plastics that can withstand extreme temperatures.
Leaving Room for Expansion: When freezing liquids or semi-liquids, leave some headspace in the container to allow for expansion as the food freezes.
Labeling and Dating: Always label and date your plastic food tubs before freezing them. This will help you keep track of how long the food has been stored and prevent freezer burn.
Cleaning and Maintenance
Proper cleaning and maintenance will extend the lifespan of your plastic food tubs and prevent the buildup of bacteria and odors.
Dishwashing vs. Handwashing
Many plastic food tubs are dishwasher-safe, but handwashing is often gentler and can help prevent warping or discoloration. If you choose to wash your tubs in the dishwasher, place them on the top rack to avoid direct heat from the heating element.
Dealing with Stains and Odors
Baking Soda Paste: A paste made from baking soda and water can effectively remove stubborn stains from plastic food tubs.
Vinegar Soak: Soaking plastic food tubs in white vinegar can help neutralize odors.
Sunlight: Exposing plastic food tubs to direct sunlight can help fade stains and kill bacteria.
Proper Storage
Store your plastic food tubs with the lids off to allow air to circulate and prevent the buildup of moisture. Nesting tubs or stacking lids can save space.
Replacing Tubs
Even with proper care, plastic food tubs will eventually wear out. Replace tubs that are cracked, warped, or heavily stained.
