Preserving the quality and integrity of the food you're storing away is what's most important. For this reason, choosing a food processing bag is an important step. All bags have different characteristics, but the most important difference seems to be material. Before making your selection, make sure you know what material options are available so that you can make the best choice.
Low Density Polyethylene
Low density polyethylene is a widely used food processing bag option because it's all about value. This material option is highly flexible, allowing you to get more food items in a single bag than you would other options. Its low price also makes it more cost effective when purchasing bags in bulk.
Lastly, low density polyethylene is also designed in a clear form, making it easier to see the contents inside the bag. The only real drawback this option presents is that it is not airtight. Unless you are placing the bag in a refrigerator, the contents of the bag likely won't last very long.
High Density Polyethylene
In terms of popularity, high density bags are the most commonly used option. This is due in part to their lightweight design and the fact that this material is highly resistant to a number of different concerns, including water and heat exposure.
High density bags can be stored in high heat areas or areas with excess moisture without the risk of the bag deteriorating. However, unlike low density polyethylene, high density bags are not as clear so you may have to label your bags in order to be sure you know exactly what's inside them.
Polypropylene
Similar to both low density and high density polyethylene bags, regular polypropylene offers superior durability and chemical resistance. However, unlike the other options, this material type is not breathable. When it comes to food storage, this is an excellent quality because the airtight style helps the food inside the bag last longer.
If you need to store away food for a long period of time or plan to store it in a retail location where it can sit on the shelf for an extended period – this serves as an excellent option. Additionally, bags made in this fashion also have a higher melting point, allowing them to be used for heat sealing or other warm applications without fear of damage.
Choosing a food processing bag that is best suited to meet your needs will ensure you get the most use out of the bag so ensure you're choosing wisely.
