FoodSaver bags are made of five layers of polyethylene and nylon, which makes them stronger than regular plastic bags and creates a complete barrier against air, moisture, and odours. Regular plastic bags are usually made of just one layer of polyethylene, which means they allow air to seep through. While it is possible to use a FoodSaver appliance to re-seal regular plastic bags without removing the air first, it is not recommended for vacuum packaging as the bags may melt or not seal properly.

Ziploc bags can be sealed using FoodSaver, but may leak after a few days
Ziploc bags can be sealed using a FoodSaver, but they may not be as effective as the official FoodSaver bags for long-term storage.
FoodSaver bags are made of five layers of material, including an outer layer of nylon, which completely prevents air and moisture from entering or exiting the bag. In comparison, Ziploc bags and other plastic bags are usually made of only one layer of polyethylene, which is a type of plastic. This single layer of plastic allows air to seep through, potentially leading to leaks over time.
Some people have reported success in sealing Ziploc bags with a FoodSaver, especially for short-term storage. However, it is important to note that Ziploc bags are not designed for vacuum sealing and may not provide an airtight seal. As a result, they may not be suitable for long-term food storage or for sous vide cooking, as the small amount of remaining air can cause the bags to float to the surface and cook unevenly.
Additionally, Ziploc bags may not be as durable as FoodSaver bags, which are designed to resist punctures and tearing. Therefore, using Ziploc bags with a FoodSaver may increase the risk of tears or leaks, especially when storing sharp or bulky items.
If you do choose to use Ziploc bags with your FoodSaver, it is recommended to cut off the zip top before sealing to ensure a better seal. It is also important to ensure that the bags are food-safe and do not contain any aluminum or metal liners, as these can be dangerous when used with a FoodSaver.

Regular plastic bags may melt when used with FoodSaver
Regular plastic bags are usually made of one layer of polyethylene, a type of plastic. In contrast, FoodSaver® Bags are made of five layers, including an outer layer of nylon, which makes the bags stronger and creates a complete barrier against air, moisture, and odours.
Some people have reported successfully using regular plastic bags with a FoodSaver. For example, one person reported using Ziploc bags with their FoodSaver sealer, noting that they needed to quickly push the seal button and release it manually. Another person reported sealing various types of bags, including potato chip bags, zip-locks, and regular supermarket generic brand food bags. However, they noted that they would not try it with a bag that had an aluminium or other metal liner.
Despite these reports of success, there are several reasons why using regular plastic bags with a FoodSaver may not be a good idea. Firstly, regular plastic bags are not as thick as FoodSaver bags and may not have as good side seals, which could affect the vacuum sealing process. Secondly, bags not intended for food use may be made of a different kind of plastic that is not as safe for food storage. Finally, the sealing bar on the FoodSaver unit may be too hot, causing the regular plastic bags to melt, or too cool, resulting in a bag that is not properly sealed.
Therefore, while it may be possible to use regular plastic bags with a FoodSaver in certain circumstances, it is not recommended due to safety and functionality concerns. It is always best to use FoodSaver-branded bags and rolls, which are designed specifically for use with FoodSaver units and are FDA-approved for food use.

FoodSaver bags are made of five layers, including nylon, which prevents air, moisture and odours from getting in or out
FoodSaver bags are designed to be used with FoodSaver machines. They are made of five layers, including an outer layer of nylon, which makes the bags stronger and creates a complete barrier against air, moisture and odours.
Other plastic bags are usually made of just one layer of polyethylene, which allows air to seep through. However, it is possible to use FoodSaver machines to re-seal other types of bags, such as Mylar (strong, thin polyester) or stiff plastic bags. For example, you can re-seal a bag of potato chips by gently pressing the top of the bag and then using the sealer with the dry vac seal.
Some people have also had success using their FoodSaver machines with Ziploc bags, generic bags bought online, and sandwich bags. However, Ziploc bags are not suitable for cooking sous vide, as they tend to leak after a day or two and float to the surface of the water, cooking unevenly.
FoodSaver bags are also reusable and can be washed and reused if they previously contained fruits, vegetables, breads, and dry goods. However, bags that contained raw meats, fish, eggs, or unpasteurized cheese should be discarded after use due to the risk of invisible bacteria.

Regular plastic bags are usually made of one layer of polyethylene
FoodSaver® Bags, on the other hand, are made of five layers, including an outer layer of nylon. This configuration completely prevents air and moisture from getting back into the bag and prevents odors from getting in or out. The nylon layer not only makes the bags stronger but also creates a complete barrier against air, moisture, and odors. FoodSaver® Bags can be simmered in water for sous vide cooking or microwaved for reheating leftovers or pre-cooked meals.
While you can technically use a FoodSaver® to re-seal regular plastic bags without removing the air first, it is not recommended. Regular plastic bags are not as thick as FoodSaver® Bags and may not have side seals that are as good or wide. Additionally, regular plastic bags may be made of a different kind of plastic that is not as safe for food use. There is also a risk of the plastic melting and creating a mess.
If you want to use your FoodSaver® to vacuum seal items, it is best to use the designated FoodSaver® Bags or rolls. However, if you simply want to re-seal a bag without removing the air, you can use Mylar-type (strong, thin polyester) or stiff plastic bags. For example, you can re-seal potato chip bags or Ziploc bags by gently pressing the top of the bag and then using the dry vac seal on your FoodSaver®.

FoodSaver bags are safe for food use and BPA-free
FoodSaver bags are designed to be used with FoodSaver appliances. They are made of five layers of polyethylene and nylon, which makes them stronger than regular plastic bags, which usually only have one layer of polyethylene. This multi-layer design also creates a complete barrier against air, moisture, and odours, helping to maintain freshness and flavour.
FoodSaver bags are safe for food use and are BPA-free. The materials used to make the bags have been determined by the U.S. Food and Drug Administration (FDA) to be safe for food use. Sunbeam Products, Inc., the company that manufactures FoodSaver products, is diligent in ensuring that their products comply with industry standards and regulations set by the FDA and Health Canada.
The bags are also versatile and can be simmered in water for sous vide cooking or microwaved for reheating leftovers or pre-cooked meals. They are also safe for use in the freezer and refrigerator.
While FoodSaver bags are designed for FoodSaver appliances, some people have reported using other types of bags with their FoodSaver machines. These include Ziploc bags, generic bags bought online, and even sandwich bags. However, it is important to note that using other types of bags may not provide the same level of vacuum sealing as FoodSaver bags, and there is a risk of the plastic melting and creating a mess.
Therefore, while it may be possible to use regular plastic bags with a FoodSaver appliance, it is not recommended. FoodSaver bags are specifically designed for this purpose and offer superior performance and safety features, ensuring that your food remains fresh and protected.
