Thickness prevents punctures, uneven sealing, and spoilage
Thickness plays a crucial role in the effectiveness of food saver plastic. While FoodSaver bags are designed with multiple layers of plastic to create a durable, airtight seal, their thickness varies. The smooth side of FoodSaver bags is typically 3 mils thick, while the textured side measures 11.5 mils. This thickness comparison also applies to GameSaver bags.
The thickness of food saver plastic is essential for preventing punctures and tears. Thicker bags, such as those with a gloss side of 4 mils and an embossed side of 10 mils, offer superior protection against punctures and wear and tear. This feature ensures that your food remains safely sealed and protected.
Additionally, thickness contributes to even sealing. Thicker bags provide a more consistent and durable seal, preventing issues like uneven sealing or leaks. This feature is especially important when vacuum sealing, as it ensures that air and moisture are effectively kept out, maintaining the freshness and quality of the stored food.
Thickness also plays a role in preventing food spoilage. By using thicker bags, you reduce the chances of punctures and uneven sealing, which can lead to air and moisture ingress. This barrier protection helps prevent food spoilage caused by oxidation, moisture, or bacterial growth. Thicker bags also enable better preservation of food during storage or cooking processes, such as sous vide cooking, where precise temperature control is required.
While thickness is important, it is also worth noting that the number of layers and the material used contribute significantly to the effectiveness of food saver plastic. Bags with multiple layers, including an outer layer of nylon, create a complete barrier against air, moisture, and odours. This multi-layer construction enhances the durability and sealing performance of the bags. Therefore, when selecting food saver plastic, consider both thickness and the number of layers to ensure optimal protection for your food items.

Bags are made of 5 layers of nylon and polyethylene
FoodSaver bags are made of 5 layers of polyethylene with an outer layer of nylon. Both nylon and polyethylene are synthetic polymers, but they have different structures. Nylon is a condensation polymer made from two different types of monomers, a diamine and a diacid, while polyethylene is an addition polymer made from a single monomer, ethylene. Polyethylene is lighter and has a lower melting point than nylon, making it more suitable for packaging. Nylon, on the other hand, is stronger and more flexible, which makes it ideal for textiles and industrial uses.
The bags are designed to be durable and BPA-free, resisting punctures and tearing to ensure that food remains protected. They are also reusable, providing an eco-friendly alternative to single-use plastic bags.
The safety of heating nylon and polyethylene bags has been a topic of discussion, with some people wondering if toxic chemicals like styrene can leach into food when the bags are heated. The consensus is that the bags are safe and do not pose any issues. The concern is related to the monomers used in the production of the polymers, as certain monomers can be toxic. However, if the bags are truly made of only polyethylene and nylon, they will not contain any styrene.
The heat resistance of polyethylene is also a factor to consider. While it is generally stable at temperatures below 195°F (91°C), it is important to note that it is not suitable for extremely high temperatures. This is where the outer layer of nylon in the FoodSaver bags comes into play, providing additional strength and heat resistance.
