Identifying which is best for your food packaging and storage needs requires in-depth knowledge of both materials.

In this article, we’ll list materials for food storage and discuss the advantages and disadvantages of plastic and glass containers. We’ll also improve your knowledge by comparing both materials and let you decide. Let’s get started.

What Types of Plastic Can Be Used for Food Storage?

Keeping water and food free of toxins and unhealthy chemicals released by certain plastic types promotes a healthy life. Many materials are difficult to disinfect and harmful to health. But a few are safe for food storage, and they include:

Polyethylene Terephthalate (PET): It’s a versatile plastic polymer with dimensional stability and excellent chemical and thermal resistance.

High-density polyethylene (HDPE): This thermoplastic material is famous for its tensile strength that can withstand high temperatures.

Low-Density Polyethylene (LDPE): It’s a lightweight plastic material with toughness and low-temperature flexibility.

Polypropylene (PP): The resin is inexpensive and resistant to heat, chemical leaks, electricity, and fatigue.

Polyvinyl Chloride (PVC): This synthetic polymer has high impact strength, offers long-term stability, and is easy to mold or extrude.

Thermoplastic elastomer (TPE): This material is supple, pliable, and simple to work with. TPEs are also extremely elastic owing to their molecular composition.

The Pros of Plastic Containers and Cookware

Affordability and accessibility with durability and convenience are benefits of plastic cookware and containers. Lightweight with size and shape versatility are also advantages. Let’s dig into the details:

Affordability and Accessibility

Plastic containers are inexpensive compared to metal, glass, and other food storage options. You can buy these materials in bulks or per pellet with favorable discounts, which is ideal for those on a budget.

Accessibility is another benefit of using plastic cookware for storing food. These reusable containers are readily available, and anyone can use them repeatedly. They can serve as a lunchbox preserving snacks, spices, rice, tea, grains, sandwiches, flour, and vegetables.

Durability and Convenience

Food storage containers are durable and long-lived because they don’t crack or break easily. Manufacturers designed these materials to withstand harsh conditions. That’s why they’re suitable for preserving meals and other everyday products.

Plastic packaging offer convenience as they’re portable, less expensive, and easy to handle or move between locations. They also don’t interact with the items they contain, making them suitable and safe for users.

Lightweight and Unbreakable

These durable containers offer high strength but are usually low in weight. You can carry plastic cookware easily without worrying about leakage. Its lightweight nature also allows quick food packaging, saving time and energy.

Plastic food storage containers are rigid and unbreakable, so you don’t have to worry about cracking. They’re recyclable and might be around for a long time if you don’t dispose of them.

Versatility in Shape and Size

Plastic food storage containers are widely used for kitchenware and meal packaging due to their versatility. They have high versatility and can serve various purposes.

These materials are moldable into solid objects with different sizes and shapes for various purposes. They can serve as milk jugs and ice cream pails, perfect for keeping bagels.

The Cons of Plastic Containers and Cookware

The potential release of toxic chemicals and not being ecofriendly are disadvantages of plastic food containers. Other cons include inadequate heat resistance and a tendency to absorb stains and odors.

Potential Release of Harmful Chemicals Like BPA and Phthalates

Plastic products release harmful chemicals like bisphenol A (BPA) and phthalates when heated. These compounds can leach into food and beverages when used for a long time.

Phthalates and BPA interfere with body hormones and affects the organ system. They might cause obesity and asthma or increase certain cancer risks.

Not Heat-Resistant and Not Recommended for Hot Food Storage or Microwave Use

Not all plastic bags or containers are heat-resistant, and microwaving with them may not be ideal. You may end up with food waste and damaged material instead of storing leftovers.

Avoid storing hot meals or beverages in plastics as they may melt, releasing harmful chemicals. These reusable containers are sensitive and aren’t a good combination with heat.

Not Eco-Friendly and Contributes to Plastic Waste

These petroleum-based storage containers aren’t biodegradable. These materials don’t break down into natural substances. Instead, they degrade into fragments called nano plastics with potential contamination properties.

Most food packaging in grocery stores is usually single-use containers and not reusable. They end up as discarded materials contributing to public waste.

Tendency to Absorb Odors and Stains

Food plastic containers and cookware tend to hold onto stains and odor, especially when kept for a long time. Since aroma molecules can travel through solid packaging, these porous materials may absorb the properties of meals stored inside them. 

Pros and Cons of Glass Containers and Cookware

Glass Containers and Cookware

Easy management, heat resistance, and oven suitability are benefits of storing food with glass packaging. Their non-toxic and eco-friendly nature are other advantages of choosing these products over plastic.


Safe and Non-toxic for Food Storage. Glass containers are perfect because they’re non-toxic and not detrimental to your health. Their non-porous surface doesn’t absorb germs, food, or stains, making them hygienic.

A glass container is safe because it doesn’t leach toxic chemicals into your meals, even when stored for an extended period. It’s also dishwasher safe and won’t contaminate your water.

Heat-Resistant and Suitable for Oven Use. Glass food storage containers contain soda lime or silica, which are heat-resistant compounds. These materials have low expansion coefficients, meaning they don’t change when the temperature fluctuates.

Glass jars are suitable for oven to use at any time due to their thermal shock resistance and high durability. You can store frozen foods in these materials and put them in a toaster, convection, or microwave oven.

Easy to Clean and Maintain. Since glass bottles are non-porous and less likely to absorb stains, they’re easier to manage and clean. They don’t have pores like plastic, so they don’t entertain food particles or allow bacteria to grow inside them.

Glass containers are sustainable, reusable, refillable, and keep food fresher. They don’t break down over time and can survive years of regular cleaning, making them easy to manage.

Eco-Friendly and Recyclable. Glass containers are materials that are easy to recycle. You can reprocess them endlessly by melting, blending, and crushing them with proper equipment.

These materials have an environmental impact as manufacturers don’t have to extract natural resources from the earth for reproduction. They also reduce waste since you don’t need to dispose of them after usage.

Glass containers


Fragile and Prone to Breaking. These materials require careful handling as they’re delicate and easily breakable. Accidentally dropping the container on the floor could shatter it.

Heavy and Bulky. Glass containers have more weight than plastic materials of similar sizes. They require more effort when transporting packaged goods.

More Expensive Than Plastic Alternatives. Glass containers usually cost more than plastics. Although they last longer and offer excellent heat resistance, they’re not cheap.

Glass vs. Plastic Container: Which Is Better?

Glass food storage containers are non-porous and don’t interact with the final product.

With glass food storage containers, your food will be safe from discoloration, odors, and the growth of microorganisms. The material is also stable when exposed to varying temperatures, ensuring that it releases no harmful chemicals. You can be assured that your food will remain fresh and safe for consumption with these food storage products.

Because of its heat resistance, you can microwave food and preserve meals in a freezer using a glass container. It’s attractive, elegant, fragile, and breakable when placed on the counter or dining table.

Plastic containers are lightweight and durable, offering tensile strength to withstand high temperatures. They are readily available and accessible to anyone on a budget. They’re unbreakable and might serve you for a long time.

Are you still wondering which is better, plastic and glass containers? Let personal needs dictate your choice, as both materials have unique properties.
