Easy Tips to Pack and Seal Food in Mylar Bags

The longevity of food items depends on various factors, however mylar bag sealing is one of the major determinants. The reason is that the sealing of these bags blocks the moisture, dirt and other contaminants from food. Here are some of the easiest tips that can help you seamlessly pack and seal your mylar bags for food packaging:

 

1. Print or Label Mylar Bags

Before packing food items in your mylar bags, you need to print product information on them. Doing so will help you comply with the regulations of the state and prevent legal issues. You should print the ingredients, manufacturing date, and expiry date on these bags. You can also paste labels of such information on your mylar bags without any hassle.

By benefiting from printing, you can use mylar food bags to boost your brand. To do so, you can print custom mylar bags with logo to enhance brand recognition. Color schemes of these bags can also be tailored to your specific preferences.

 

2. Fill Bags with Food Products

Once you have designed your mylar bags, it’s time to fill them with your food products. Although packaging bags are personalized in accurate sizes to pack the product portions, you need to standardize the quantity. For instance, to pack the powder in 250 g mylar bags, measure the weight after filling every bag.

Some items aren’t measured in weight or volume; they are packed in numbers. For example, mylar packaging bags for cookies and candies come with a specific number of items. If you are selling a pack of 12 cookies, you must carefully include 12 pieces in every packaging bag to ensure quantity standardization.

 

3. Add Oxygen Absorbents to Packaging Bags

Mylar packaging bags are quite durable and resistant enough to keep products packed in them pristine. However, added features make these bags more suitable for keeping food items fresh for a long time. Some of such features are vacuum sealing and oxygen absorbents.

To create vacuum-sealed mylar bags, you need to extract air from the bags after packing products inside. Afterwards, seal these bags tightly. Without the air the shelf-life of food items can be extended by many folds.

You can also add oxygen absorbers to these bags that help keep food items fresh for a long duration. In the absence of oxygen, microbes can’t grow in food items. You can use iron-based powder sachets as an excellent oxygen absorber in your food mylar bags.

 

4. Use Heat-Sealing or Add Zip Locks

Finally, seal the loaded mylar bags using a reliable sealing mechanism. You can choose from various options in this regard. The most reliable ones include heat-sealing and zip locks.

Heat-sealing is suitable for one-time-use items or products with shorter consumption lives. To heat seal mylar bags, thermoplastic materials are attached at the opening of bags. Some common thermoplastic materials include EVA (Ethylene Vinyl Acetate) and EAA (Ethylene Acrylic Acid). These materials melt and firmly stick on the surface under high temperature and pressure creating a water and air-resistant seal.

For reusable products, ziplock mylar bags are more suitable. The reason is that such sealing can be reopened and closed with a breeze. Bags with such sealing mechanisms are more suitable for packing food items like legumes, oats, nuts, etc.

 

Wrap Up

Packing and sealing mylar bags appropriately is essential to enhance the shelf life of food products packed inside them. By not following the right steps, you may leave holes or tears in these bags that expose food to environmental contaminants. We hope the above tips on packing and sealing mylar bags for food packaging help make it easier for you.
