Custom Mylar Bags

Mylar bags are flat bags and stand up bags. Generally, it is composed of two or three layers of materials with aluminum plating, which can be matched with windows, zip lock (ordinary zip lock, child-resistant zip lock, etc.).

Mylar bag was originally derived from Smell proof bag. Mylar bag is generally suitable for Cannabis Food Packaging. From the change of materials, one side is transparent, one side is aluminum foil, and then through changes in printing process, so as to attract customers’ desire to buy.

Mylar bags provide an efficient and effective way to preserve long-term food products. Mylar bags are ideal for long-term food storage because they offer protection and storage for any food product by blocking out light while reducing the amount of oxygen and moisture that can enter the bag over time.

In its basic form, mylar is a clear material made from polyester resin. Mylar contains many desirable properties for emergency long-term food storage such as gas and moisture resistance, chemical stability, and high tensile strength.

1) Oxygen Protection
Regular plastic bags and Ziploc plastic bags in seeps oxygen back into food products and does not provide any light protection compared to Mylar Bags. Oxygen and sunlight can cause discolorations, loss of taste, compromise product freshness and allow insects to breed. Mylar Bags provides an effective oxygen barrier to help preserve your food longer while maintaining its freshness. The thicker the Mylar Bag, the lower the oxygen transmission rate.

2) Light Protection
Some types of food are more sensitive to light. When exposed to light, the temperature of the product can increase. Oil based products such as nuts, biscuits, crisps, and chocolate will be more vulnerable to rancidity and discolorations. Mylar Bags that are 4.0 and above can completely block out light. By keeping the light out, the product can stay cooler and reduce the risk of rancidity.

3) Odour
Most foods absorb odour, which affects the taste of food products and the viability of your food storage. Plastic and paper absorb Odour which can affect the quality of your food storage. Mylar bags are laminated to aluminum which creates an oxygen barrier that prevents contamination against odour and gases.

4) Moisture Protection
Moisture can destroy your food when in storage. Dampness created by moisture can cause mould, fungus, insects, and bacteria to thrive and negatively affect your food.
Mylar Bags are laminated in several layers with aluminum foil and are waterproof. Food stored in a properly sealed Mylar Bag would remain completely dry from any external water sources.

The two most commonly used sizes for storing food products are the one-gallon size Mylar bag (about 10” x 14”) and the five-gallon size (about 20” x 30”).

The gallon bags are ideal for grains, dried powdered foods (like powdered milk), spices, hard candy, salts, and other baking ingredients. In addition, gallon bags are useful for protecting valuables including ammo and medical supplies. When shopping for gallon sized bags, you should look for a minimum thickness of 3.5 to 4 mil.

The large, 5-gallon bags are typically used to line a 5 or 6-gallon plastic bucket. You will want to be sure to use food-grade buckets as well as food grade mylar foil. The bag is first placed in the bucket and then filled with the product. The bag is sealed before closing the bucket with a tight-fitting lid.

Dry pack pouches, metalized storage bags and Mylar have something in common- they are all alike! Don’t be confused when your seller refers to Mylar bags as such. All of these are made from the same Mylar material. Mylar is just one brand of polyester film, like Xerox is a brand of a copier machine.
