What Is Mylar Bag?
Mylar bags are a kind of flexible packaging that is created using a specific type of polyester film known as BoPET (Biaxially Oriented Polyethylene Terephthalate).
This material is famous for its exceptional features. Such as its high tensile strength, chemical stability, and great capabilities as a gas and moisture barrier. Because of its remarkable capacity to block out external elements that might damage the quality of the contents, custom mylar bags are used widely to keep the fresh. And the integrity of a wide variety of goods. This is mostly because mylar bags are very durable.
What Is The Function Of A Mylar Bag
A Mylar bag’s major purpose is to provide a packaging solution that is both protective and long-lasting. This solution shields the contents of the bag from any external influences that might compromise its freshness, integrity, or durability.
Mylar bags are used for many important purposes, including the following:

When Was Mylar Invented
In the middle of the 20th century, the DuPont firm developed a form of polyester film that later became known under the brand name Mylar. Initial development for it took place during the 1950s, and was first shown to the public for display at an exhibition held that year.
Mylar is well-renowned for its remarkable qualities, such as high tensile strength, chemical stability, transparency, and resistance to moisture effects. Due to these properties, Mylar quickly found applications across an array of fields – the packaging industry, electronics industry, and insulation sector, to name but a few – quickly becoming popular throughout its use; today it continues to serve an integral role in cutting edge tech as well as commonplace goods alike.
Mylar Bag Size Chart
Mylar bags come in various sizes to accommodate different products and purposes. While specific size options can vary depending on the manufacturer and supplier, here is a general mylar bag size chart that includes common dimensions:
Small Mylar Bags
- 3 x 5 inches
- 4 x 6 inches
- 5 x 7 inches
Medium Mylar Bags
- 6 x 9 inches
- 7 x 10 inches
- 8 x 12 inches
Large Mylar Bags
- 10 x 12 inches
- 12 x 16 inches
- 16 x 24 inches
Extra-Large Mylar Bags
- 18 x 24 inches
- 20 x 30 inches
- 24 x 36 inches
Remember that there is the option to purchase mylar bag dimensions in either a flat or a stand-up form. The kind of goods you wish to package. And the space required for display or storage will guide your decision between these two formats.
In addition, the thickness of a bag can vary (it is measured in mils), which can affect its ability to operate as a barrier. Because of this, it is vital to pick the suitable mylar bag food storage chart for the product depending on the requirements for its preservation.
How To Choose The Correct Thickness
Determine the appropriate thickness based on the dimensions of your package. Thicker mylar bags may be necessary when storing merchandise over longer time frames; I advise against snack size mylar bags thinner than 4.5 mile as these tend to tear more easily than thinner versions. Extra large sizes range in thicknesses between 4.5-6.5 miles thicker mylar bags might be wiser in such circumstances. The reason for this is that the thicker bags provide superior insulation, preventing your goods from being damaged by the environment.
Thinner Mylar bags (less than 4.5 miles) do not insulate or protect as well and should not be used for long-term storage.
The 3.5 gram mylar bag size is a good option if you’re on a tighter budget. Care should be used while storing and handling to prevent ripping.
As a general rule of thumb, it’s best to use the heaviest mylar bag that can fit your goods. Check that items of any weight can be stored in their original containers. Choose packaging that is both strong and protective of your goods.
Can A Mylar Bag Be Used In Cooking?
Many customers that I know who reheat food in an oven while it is still packaged use RCPP instead of LDPE as material specification because when exposed to heat LDPE can generate strong plastic scents which could damage food components.
As such, mylar bags that will be used in cooking environments must utilize special RCPP material – customers should ensure they fully comprehend why these particular bags exist prior to buying anything! This serves as a good reminder for them when purchasing any product – they should make sure that their understanding covers both packaging and use before purchasing something from stores or websites.
How To Confirm If Your Mylar Bag BPA Free Or FDA Food-Grade?
Because of this, mylar bags are often manufactured using a lamination process that involves many layers of film. We need to make certain that LDPE or RCPP material is used in all areas of the product that comes into direct touch with food.
You should make it clear to your manufacturers that the film-blowing process must solely include the usage of raw materials. In addition, to demonstrate that it is safe for use in food items, they are required to provide a BPA and food-grade testing pass report from the FDA to guarantee that your mylar bag satisfies the necessary test criteria.
You always have the option of requesting that your manufacturers offer you samples from the same batch that contains the inner layers, which are either LDPE or RCPP. After that, you have the option of sending the samples on your own to the SGS laboratory in your area, or if you are located in the United States, you can submit them to the FDA for testing.
How To Use Mylar Bags For Food Storage Properly?
Proper storage of perishable items such as food requires placing them into Mylar bags to preserve freshness for as long as possible. Mylar bags provide the optimal environment to do just this as they block air, light, moisture, and pests from reaching perishable products.
The following is a detailed explanation of how to store food in mylar bags:
- What You’ll Need is
- Mylar bags (in whatever size you’ll need to store your foodstuff).
- Oxygen removers and/or desiccant packets (to manage humidity and oxidation).
- Bag heat sealer (to keep the contents safe).
- (Optional) Food-grade buckets or containers (for extra safety)
- Get Your Food Ready
Be sure that all food you are storing is clean, dry, and free from bacteria or pollutants before placing it in Mylar bags for storage.
Mylar bags can help store various kinds of foods ranging from grains and rice, beans, and pasta as well as dry fruit Mylar storage bags – flour sugar etc can often become spoilt when exposed to moisture; packaging them correctly prevent this happening.
- Insert Oxygen Absorbers or Desiccant Packets
By removing oxygen from the r bag, deterioration and the development of germs can be avoided with the use of oxygen absorbers.
Desiccant packets remove moisture from food, maintaining its dryness and freshness. Before putting food in the bag, add the required amount of oxygen absorbers or desiccant tablets. For the suggested serving size, have a look at the food’s packaging or ask the maker.
- Fill The Mylar Bag
Fill the bag with your food supplies. Allow for sealing and some expansion of the contents if they require it. If you overfill the bag, it will be more difficult to close.
- Seal The Mylar Bag
Close the Mylar bag with care using a heat sealer. Keep out air, water, and vermin by making sure the seal is tight. Apply steady pressure as you run the heat sealer along the open end of the bag. For extra safety, you can use two seals.
- Excess Air Must Be Eliminated
After closing a bag, if there is still air within, you can either push down on the contents to release the air or use a vacuum sealer attachment.
Food held with less air has a longer shelf life.
- Bag Must Be Dated And Labeled
Clearly mark the contents and packing date on the mylar packaging bag. The “first in, first out” (FIFO) concept dictates that the oldest things are used first, therefore keeping track of how long they’ve been in storage is essential.
- Put Away Somewhere Cool And Dark
Maintaining food quality requires a cold, dark, and dry environment for the sealed mylar bags. Avoid exposure to extreme temperatures and direct sunshine. Food-safe containers or buckets should be used to further insulate the sealed bags from environmental elements and pests.
- Inspect For Leaks And Breaks On A Regular Basis
Check your mylar bag sizes regularly for tears, punctures, and broken seals. If there are problems, put the contents in a fresh Mylar bag and seal the old one.
Depending on the kind of food and the circumstances under which it is maintained, the shelf life of food kept in mylar bags can be prolonged to several years. It’s important to keep food fresh by replacing oxygen absorbers and desiccant packets regularly. By following these instructions, you can keep food in bags. And utilize them whenever you choose.
Have a good day ahead!
