Brown kraft paper bags have become increasingly popular for storing everything from bulk grains to homemade treats. Their eco-friendly nature and rustic appeal make them a favorite among environmentally conscious consumers. But what happens when you want to extend the shelf life of items stored in these bags? Can your trusty FoodSaver vacuum sealer work its magic on brown kraft paper bags?
The short answer is: it's complicated. While FoodSaver sealers are designed primarily for plastic bags and rolls, many users have experimented with sealing brown kraft paper bags with mixed results. Understanding the limitations, techniques, and alternatives can help you make the most of both your FoodSaver and your kraft paper storage needs.
FoodSaver vacuum sealers operate on a straightforward principle: they remove air from specially designed bags and create an airtight seal using heat. The heating element reaches temperatures high enough to melt and fuse the plastic material of FoodSaver bags, creating a permanent seal that keeps air, moisture, and contaminants out.
The key to successful vacuum sealing lies in the material's ability to withstand heat and form a secure bond when heated. FoodSaver bags are made from multiple layers of plastic specifically engineered to work with the sealer's heating element and vacuum mechanism.
Brown kraft paper bags present several challenges when used with FoodSaver sealers:
Kraft paper is made from wood pulp and lacks the thermoplastic properties of FoodSaver bags. When exposed to the high heat of a vacuum sealer, kraft paper may scorch, burn, or simply fail to create a proper seal. The paper fibers don't melt and fuse together like plastic materials do.
Unlike plastic bags, brown kraft paper bags are porous. Even if you manage to create what appears to be a sealed edge, air can still pass through the paper fibers themselves. This porosity defeats the primary purpose of vacuum sealing, which is to create an airtight environment.
The vacuum process can cause kraft paper bags to collapse or tear due to their relatively thin construction. The bags weren't designed to withstand the negative pressure created during the vacuum sealing process.
While direct vacuum sealing may not work effectively, there are several workarounds and alternatives:
Place your brown kraft paper bag inside a FoodSaver plastic bag. This approach allows you to maintain the aesthetic and eco-friendly benefits of kraft paper while still achieving an airtight seal. The plastic bag provides the necessary barrier properties, while the kraft paper bag serves as an inner container.
Some users have had limited success using only the sealing function of their FoodSaver (without the vacuum feature) on kraft paper bags. This requires:
· Using the lowest heat setting available
· Placing parchment paper between the heating element and the kraft paper
· Working quickly to avoid scorching
· Accepting that the seal may not be as reliable as with plastic materials
For short-term storage, you can fold the top of the kraft paper bag multiple times and secure it with clips. While this doesn't create an airtight seal, it can help maintain freshness for items that don't require complete air exclusion.
Some manufacturers now offer vacuum sealer bags with kraft paper exteriors and plastic interiors. These bags combine the visual appeal of kraft paper with the functional benefits of vacuum sealing technology.
FoodSaver offers jar sealing attachments that can create vacuum seals in mason jars. You can place items from kraft paper bags into jars for longer-term vacuum storage while keeping the original packaging for reference.
Hard-sided vacuum containers work well for items originally stored in kraft paper bags. These containers can be vacuum sealed using FoodSaver handheld sealers or pump attachments.
While brown kraft paper bags may not work well with vacuum sealers, they have their own strengths:
Breathability: Some items like certain baked goods benefit from the breathability that kraft paper provides, preventing sogginess that can occur in completely airtight environments.
Eco-friendliness: Kraft paper bags are biodegradable and often made from recycled materials, making them an environmentally responsible choice.
Food Safety: High-quality kraft paper bags are generally food-safe and don't contain the chemicals sometimes found in plastic packaging.
If you prefer to stick with brown kraft paper bags, consider these freshness-extending techniques:
Store kraft paper bags in cool, dry locations away from direct sunlight. Consistent temperature and low humidity help maintain the quality of stored items.
Food-grade oxygen absorber packets can be placed inside kraft paper bags before sealing with clips or tape. These packets help reduce oxidation without requiring vacuum sealing.
Practice first-in, first-out rotation to ensure items in kraft paper bags are used while still fresh.
The decision between using FoodSaver vacuum sealing and brown kraft paper bags depends on your specific requirements:
Choose vacuum sealing when you need maximum freshness extension, are storing items long-term, or are dealing with foods prone to spoilage.
Stick with kraft paper bags when you want eco-friendly packaging, are storing items short-term, or are packaging items that benefit from some air circulation.
Rather than forcing incompatible technologies to work together, consider developing a storage system that uses each method for its strengths. Use brown kraft paper bags for short-term storage, gift packaging, or items that benefit from breathability. Reserve your FoodSaver for long-term storage needs using appropriate plastic bags or containers.
You might also explore hybrid approaches, such as using kraft paper bags inside vacuum-sealed containers or investing in specialized equipment designed for paper-based packaging.
The key is matching your storage method to your specific needs rather than trying to make one solution work for every situation. By understanding the limitations and strengths of both brown kraft paper bags and FoodSaver sealers, you can create an effective storage system that serves all your food preservation needs.
