How do PE food wraps compare to aluminum foil for food storage?

When it comes to storing food, two of the most common options that come to mind are PE food wraps and aluminum foil. As a supplier of PE food wraps, I've seen firsthand how these products stack up against each other. In this blog, I'll break down the pros and cons of each, so you can decide which is the best fit for your food storage needs.

What Are PE Food Wraps?

PE, or polyethylene, is a type of plastic that's widely used in food packaging. PE food wraps are thin, flexible sheets that are designed to cling to surfaces, making them great for covering food containers, plates, and even bowls. There are different types of PE food wraps available, such as PE Kitchen Wrap, PE Cling Wrap, and PE Foodservice Film. These wraps are often transparent, which allows you to easily see what's inside without having to unwrap them.

What Is Aluminum Foil?

Aluminum foil is a thin sheet of aluminum metal that's been rolled into a very thin layer. It's a popular choice for food storage because it's durable, flexible, and can withstand high temperatures. Aluminum foil can be used to wrap food directly, cover baking dishes, or line pans. It's also great for keeping food warm, as it reflects heat.

Comparing PE Food Wraps and Aluminum Foil

Cost

One of the first things people often consider when choosing a food storage option is cost. PE food wraps are generally more affordable than aluminum foil. They're often sold in large rolls, which means you can get a lot of coverage for a relatively low price. Aluminum foil, on the other hand, can be more expensive, especially if you're using it for large items or on a regular basis.

Flexibility and Ease of Use

PE food wraps are incredibly flexible and easy to use. They can be stretched and molded to fit almost any shape or size of container. The clingy nature of PE wraps means they stick to themselves and the surface of the food, creating a tight seal. This makes them ideal for covering irregularly shaped items like leftovers on a plate or a half-eaten sandwich.

Aluminum foil is also flexible, but it can be a bit more difficult to work with. It doesn't have the same clingy quality as PE wraps, so you may need to use tape or fold it over itself several times to create a seal. However, it's great for wrapping large items like roasts or baking sheets because it can be easily shaped and folded.

Heat Resistance

If you're planning to cook or reheat your food in the oven, grill, or microwave, heat resistance is an important factor to consider. Aluminum foil is highly heat-resistant and can withstand temperatures up to about 660°F (350°C). This makes it a great choice for baking, roasting, and grilling. You can wrap your food in aluminum foil and cook it directly on the grill or in the oven without worrying about the foil melting.

PE food wraps, on the other hand, are not designed for high-heat applications. Most PE wraps can only withstand temperatures up to about 220°F (104°C). If you expose them to higher temperatures, they can melt or release harmful chemicals. However, some PE wraps are labeled as “microwave-safe,” which means they can be used in the microwave at low to medium temperatures. Just make sure to follow the manufacturer's instructions carefully.

Moisture and Air Barrier

Another important aspect of food storage is keeping your food fresh. Both PE food wraps and aluminum foil can help create a barrier against moisture and air, which can prevent food from drying out or spoiling.

PE food wraps are excellent at creating an airtight seal, which helps to keep food fresh for longer. They can also prevent moisture from escaping, which is great for keeping food moist and juicy. However, they're not completely impermeable to air and moisture, so over time, some air may still seep in.

Aluminum foil is a better barrier against air and moisture than PE wraps. It creates a more complete seal, which can help keep food fresh for even longer. It's especially good for storing foods that are prone to drying out, like bread or cookies. However, it's important to note that if the foil is not wrapped tightly enough, air and moisture can still get in.

Recycling and Environmental Impact

In today's world, many people are concerned about the environmental impact of the products they use. Both PE food wraps and aluminum foil have different considerations when it comes to recycling.

PE food wraps are made of plastic, which can be difficult to recycle. In many areas, PE wraps are not accepted in curbside recycling programs because they can get tangled up in recycling machinery. However, some companies are starting to offer recycling programs for their PE wraps, so it's worth checking to see if there's an option in your area.

Aluminum foil is more easily recyclable than PE wraps. It can be recycled over and over again without losing its quality. However, it's important to make sure the foil is clean before recycling it. If it's covered in grease or food residue, it may not be accepted at the recycling center.

When to Use PE Food Wraps

PE food wraps are a great choice for everyday food storage needs. Here are some situations where PE wraps shine:

• Covering leftovers: Whether it's a plate of pasta or a bowl of soup, PE wraps can easily cover and seal your leftovers, keeping them fresh in the fridge.
• Packing lunches: PE wraps are perfect for wrapping sandwiches, snacks, and other lunch items. They're lightweight and easy to carry, and they can help keep your food fresh until lunchtime.
• Storing delicate foods: The flexibility and clinginess of PE wraps make them ideal for wrapping delicate foods like berries or cheese without crushing them.

When to Use Aluminum Foil

Aluminum foil has its own set of advantages and is best used in certain situations:

• Cooking and baking: As mentioned earlier, aluminum foil can withstand high temperatures, making it a great choice for cooking and baking. You can use it to line baking sheets, wrap potatoes for roasting, or cover chicken for grilling.
• Keeping food warm: Aluminum foil's ability to reflect heat makes it perfect for keeping food warm for longer periods. You can wrap hot food in foil and transport it without it losing too much heat.
• Storing foods in the freezer: Aluminum foil is a good choice for storing foods in the freezer because it can help protect them from freezer burn. It creates a better barrier against air and moisture than PE wraps.

Conclusion

In conclusion, both PE food wraps and aluminum foil have their own unique benefits and drawbacks. PE food wraps are more affordable, flexible, and easy to use, making them a great choice for everyday food storage. They're also a good option for covering delicate foods or packing lunches. However, they're not suitable for high-heat applications and can be difficult to recycle.

Aluminum foil, on the other hand, is more heat-resistant, creates a better barrier against air and moisture, and is easier to recycle. It's ideal for cooking, baking, and keeping food warm. However, it can be more expensive and a bit more difficult to work with.
