3 Things to Consider for Mylar Bags for Food Storage
Most people often ask, “How to properly use Mylar bags for long-term food storage?”. The answer is that one must consider the following factors when customizing food Mylar bags:
Thickness
You must understand your product packaging and storage needs to customize the Mylar bag with the right thickness. For example, if you want to customize small Mylar bags for single-serving food items for retail display, the standard thickness will be around 3-4 mil. Likewise, for long-term storage in large mylar bags, you must customize the 7-10 mil thickness.
Degassing Valve
Most food items release carbon dioxide, which may affect the quality and longevity of the product. This is why a degassing valve is added to mylar bags, especially those used for coffee, to release excess carbon dioxide (CO2). This one-way valve helps maintain the freshness and flavor of the food items by preventing the bag from swelling or bursting due to gas buildup. Also, it protects the products against oxidation.
Oxygen Absorbers
Oxygen absorbers are small packets designed to remove oxygen from sealed Mylar bags, extending the shelf life of perishable products by inhibiting bacterial growth.
Final Words!
Concluding the discussion with the fact that now industries are highly relying on the custom Mylar bags due to their excellent barrier properties, functionality, and versatility. So the significance of Mylar bags is completely undeniable!
Mylar bags are ideal for storing food for a longer period of time because they have excellent properties against oxygen, moisture, and air. They are also tear-resistant, ensuring food safety from contamination.
The longevity of custom mylar bag packaging depends on how you customize it and how you take care of it. Mylar bags with higher thickness are tear-resistant, ensuring durability. In short, a mylar bag lasts for up to 20 years if sorted and maintained well.
The following items should not be stored in custom Mylar bags:
- Moist and fresh food items.
- Sharp items with rough edges.
- Chemicals and Reactive Substances.
- Products that produce gas and ferment.
