Are Resealable Zip Lock Bags Food Safe?

Zip lock bags are fast becoming a perfect and versatile packing option for food and non-food items for different industries and private companies.

However, many people are still skeptical about using resealable zip lock bags hence the question; are resealable zip lock bags safe for food items?

The simple answer to this question is YES; they are safe for food storage because they are made from virgin LDPE material.

Low-Density Polyethylene (LDPE) is one of the most inexpensive and versatile plastics. It possesses high ductility, more flexibility, and high impact strength.

An LDPE material is softer than High-Density Polyethylene (HDPE) due to its increased branching characteristic. Although this gives it a lower tensile strength, it has greater ductility. It has a high resistance to moisture and chemicals and is commonly found in plastic bags.

LDPE is typically used as a film in food packaging for storing different food items such as meat, frozen foods, bread, bakery goods, and liquid packaging such as milk cartons.

Awesome Pack Ziplock Bags

Businesses in Australia, such as frozen foods manufacturing companies, bakeries selling bread, and liquid packaging companies, can use Zip lock bags when packaging food items.

It's a no-brainer that zip-lock bags are an excellent item to have in your kitchen. They can be used to store practically any food, from cereal to lunch, fruit and vegetables and of course, leftover curry.

Most people don't know the vast number of benefits these little packages can offer you. Zip Lock bags are easy to use, versatile, low maintenance, and can save you time and money in the long run.

Let's take a look at some advantages of using Ziplock bags.

1. They are inexpensive and help you to save money.

We've all been there. We go to the supermarket, buy our favourite food, take it home and realise we have no way of storing it properly. We don't have enough containers and don't want to let the food go to waste. Both are common dilemmas, solved by zip lock bags!

They are extremely low maintenance, so you will not be wasting money on expensive storage containers (that most likely will never be used again after the first use) but on bags that you can use again and again!

And if you still aren't convinced they are worth it, compare how much they cost with other options: Zip Lock bags are generally less than $10 for 50 pieces. That's a small fraction of the cost of containers!

They can be purchased at just about any supermarket or department store and are usually sold in large packs. This means you don't have to worry about buying too many or leaving some stuck at the back of a kitchen drawer and forgetting them.

Most people will already have a pack of these lying around their house, just waiting for an opportunity to use them.

2. They provide a versatile way to store food

They're the most versatile bags around. Use them to store food in the fridge and freezer, or take them out with you on short-term trips and use them as a cooler bag. You can also use them to store toys, clothes, and knick-knacks in your style! Just be sure not to mix different types of foods in one bag! That wouldn't be a great idea, would it?

3. They are easy to clean

As mentioned above, zip lock bags are usually sold in packs of 5 or 10, making tracking the bags and contents very easy.

When used, you can drop them into a bin or sink and then wash and sterilise the bag for reuse later. You don't have to worry about keeping track of individual bags because they're only sold in large packs!

4. They are easy to save time cooking your food

When cooking or preparing healthy ingredients daily, they mustn’t go off before being consumed.

Using zip lock bags ensures your food is fresh and ready for preparation. Put all the ingredients into a separate bag, close it, throw it in the fridge, and you're done!

No need to worry about keeping track of individual ingredients or storing them properly because they've already been packaged up in a zip lock.

5. They are perfect for storing any food

Compared to plastic bags, zip lock bags can store various types of food. This makes them a perfect item in your kitchen because you'll have the snug fit you need when drying out fruit or vegetables or keeping leftovers.

Disadvantages of using Zip lock bags

The Zip lock bags are convenient because they keep your food fresh without extra containers. Yet despite this convenience, there may be some drawbacks that outweigh these benefits; let’s check them out.

1. They are not eco-friendly.

The most apparent drawback of zip lock bags is that they cannot be recycled, unlike glass or other materials. Such bags have a lot of plastic, making it hard to recycle efficiently.

This is why it would be more advantageous to use other storage methods instead of zip lock bags because they are not biodegradable.

Additionally, you do not know how long the chemicals from the plastic will stay in your food after being heated because many of these chemicals leach into your food easily when heated.

2. They can explode when heated.

The chemicals from the plastic can leach into your food whenever it is heated. Those chemicals can be highly volatile and might not just leak out of the zip lock; if they do, they may build up to a dangerous level.

This might lead to explosions or even food poisoning. The best way to prevent these explosions is not to heat your food in zip lock bags, always use other storage means, like glass containers or pottery, and avoid using the zip lid altogether!

3. They may not be microwave safe.

The problem with zip lock bags is that they are not protected from heat; even if you use the best bags, there is no guarantee of safety.

It may be that the strength of heat used depends on other factors such as what materials you are using and what type of food is being enclosed. The best thing to do is to never use the zip lock bag for microwaving food and always use other storage means.

4. They are not suitable for liquids or detergents.

Some chemicals from the plastic can get into your foods when heated using zip lock bags. These chemicals might also be consumed in large quantities while eating, which would cause some health issues.

Furthermore, these chemicals can leach into your food through your fingers while touching the bag, which threatens the safety of these foods. It would be best to avoid using zip locks to store these foods as they may easily come off through the holes.
