Temperature Limits Of Food Packaging Materials

Published on  Updated on  

“Can you put take out containers in the microwave?” or “Is this container safe for hot foods?” are questions you may oftentimes ask yourself when packaging take out orders. The answers to these questions will help you understand which materials should be used when packing certain types of foods to eliminate messy accidents during transport. Instead of having to constantly look up which container materials are appropriate for your meals, you can use our guide to help you decide what type of container is best for each dish.

Plastic

Known for being rigid and leak-resistant, plastic containers are extremely durable. They can take a few bumps in the road while still keeping your meals protected and intact. Great for hefty meals like pasta or rice dishes, this material can hold the weight of large to-go orders. However, not all plastic containers can endure the same temperatures.

Polyethylene Terephthalate (PET)

PET containers are often clear, durable, and not easily punctured, which means they can protect your foods from outside contamination. These take out boxes are also recyclable if disposed of properly. When exposed to high temperatures, food-safe PET can leach the contaminant, antimony, into your foods. On the other hand, cold foods such as salads and wraps can be packaged and stored into PET containers.

PET Temperature Limits:

  • Up to 120°F

Use PET containers for: 

  • Packaging cold foods
  • Storing meals in the fridge or freezer

Polypropylene (PP)

PET containers  are often clear, durable, and not easily punctured, which means they can protect your foods from outside contamination. These take out boxes are also recyclable if disposed of properly. When exposed to high temperatures, food-safe PET can leach the contaminant, antimony, into your foods. On the other hand, cold foods such as salads and wraps can be packaged and stored into PET containers.

PP Temperature Limits: 

  • Minimum temperatures: -4°F to 14°F
  • Maximum temperatures: 212°F to 266°F

Use PP containers for: 

  • Packaging hot and cold foods
  • Reheating meals in the microwave
  • Storing meals in the fridge or freezer

Polylactic Acid (PLA)

Eco-friendly and sustainable, PLA plastic containers are made from renewable sources, like cornstarch, sugarcane, and other plants. Derived from natural resources, this type of container is commercially compostable and biodegradable. The disadvantage of this material is that it can easily melt in high temperatures and should therefore not be left inside of a car on a hot day.

PLA Temperature Limits:

  • Up to 140°F

Use PLA containers for:

  • Packaging cold foods

Bagasse

Made from sugarcane pulp, bagasse containers are commercially compostable and biodegradable, making it the perfect option for eco-friendly restaurants. It is naturally grease-resistant and can retain the heat of your meals to a certain extent. This eco-friendly food packaging material can withstand a wide range of temperatures so you can package any type of meal.

Bagasse Temperature Limits:

  • Around -13°F to 428°F

Use Bagasse containers for: 

  • Packaging hot and cold foods
  • Reheating meals in the microwave
  • Storing meals in the fridge or freezer

Foam

Foam containers or polystyrene foam are used as vessels for take out containers, drinks, and retail packaging. They are lightweight and fairly sturdy and can be torn if not handled properly. The downside to these is that they are very harmful to the environment and are not accepted by curbside recycling programs because they are often contaminated with food, making them difficult to clean. Because they are harmful to the environment, an increasing amount of cities and states, such as San Francisco and New York, have banned foam containers or are in the process of banning them.

Use foam containers for:

  • Storing meals in the fridge

Paper

Many operators like to choose paper containers because they are available in a variety of colors that match the color scheme of their establishment. Some paper take out containers for restaurants even have a grease-resistant lining to prevent oils from soaking through and creating a mess. They retain heat fairly well but don’t expect paper containers to keep your food warm for an extended period of time. However, most are recyclable and eco-friendly. When using paper containers, check to see if they are microwave-safe. For example, paper containers with a PP liner are microwave-safe, but paper containers with a PE liner are not.

Paper Temperature Limits: 

  • Temperature limits depend on the type of plastic lining. Ask your vendor about your product’s temperature limit.

Use paper containers for: 

  • Packaging hot foods
  • Reheating meals in the microwave (if microwave-safe)

Aluminum

Aluminum containers allow prepacked entrees to be reheated in the oven and are typically used for packaging a large amount of food for take out or catering events. These containers are preferred by caterers because they find it convenient to cook dishes in the oven and simply take them out for serving all in the same vessel. Plus, they’re grease-resistant and flexible, making them great for holding hefty dishes.

Aluminum Temperature Limits: 

  • -20°F to 400°F

Use aluminum containers for: 

  • Baking dishes in the oven
  • Storing meals in the fridge or freezer
  • Packaging hot and cold foods

Advantages Of Tailored Food Packaging

In addition to understanding the right materials for packaging different foods, incorporating custom food packaging into your strategy can greatly benefit your business. Custom food packaging goes beyond practicality; it enhances your brand image, ensures better customer satisfaction, and provides an opportunity to stand out in a competitive market. Here's how:

1. Brand Recognition

Custom packaging with your logo, tagline, or brand colors can create a memorable impression on your customers. When people see your unique packaging, it reinforces your brand identity and helps them associate positive experiences with your food. Over time, this increases brand loyalty and word-of-mouth referrals.

2. Improved Customer Experience

Tailored packaging ensures your food arrives in the best condition possible. Custom features like compartments for sauces or vented lids for steam release can make meals more enjoyable for your customers, improving their overall dining experience.

3. Sustainability Appeal

Custom food packaging can also reflect your commitment to sustainability. By choosing eco-friendly materials such as PLA or bagasse, you can align your brand with environmentally conscious values, which is increasingly important to modern consumers. Highlighting these choices on your packaging can further boost your brand's appeal.

4. Enhanced Product Safety

With the right customization, your food packaging can ensure optimal safety for hot and cold foods. For instance, customized PP containers with leak-resistant seals are ideal for soups or curries, while custom aluminum trays can prevent spills during transport for baked dishes.

5. Marketing Opportunity

Your packaging can serve as a mobile advertisement. Whether customers carry it in public or share pictures of their meals online, your brand gets visibility. Incorporating QR codes or social media handles onto your custom packaging encourages digital engagement, helping you connect with your audience on multiple platforms.

6. Cost Efficiency

Custom food packaging can be designed to optimize material usage and reduce waste. Instead of one-size-fits-all containers, you can create packaging tailored to the size and shape of your portions, lowering costs and reducing environmental impact.

By combining material knowledge with custom packaging, you ensure not only that your food stays fresh and safe but also that your brand leaves a lasting impression on your customers. This blend of functionality and aesthetics makes custom food packaging an essential investment for any food business.
