Mylar’s Origin & History
When Mylar was developed in the 1950’s it is doubtful that the inventors realized that Mylar would one day be a very important material for the recreational and medical cannabis industry. Mylar was developed to be a superior alternative cellophane and quickly replaced cellophane. Mylar has been used in many applications including by NASA. for space suits and in experimental balloons Mylar is technically a BoPET plastics, which is basically a specially designed polyester. Marijuana and cannabis packaging is only one of the uses for Mylar, it is used in many applications because of its unique barrier properties.
Mylar as a Barrier Packaging Solution
Mylar can be combined with other materials to produce packaging with very special characteristics.
- Heat Resistance
- Smell and Odor Proofing
- Moisture control
Mylar is Great For Weed Packaging
Economical: Mylar bags are more economical that plastic vials.
Moisture Control For Edibles: Mylar prevents the transmission of moisture into and out of the bag. Moisture Transmission is very important for edibles.
More Child Resistant: Mylar bags have many child resistant features. Unlike cheaper bags, it is harder for children to rip or tear Mylar especially when combined with Nylon.
Common Questions about Mylar Bags
- What Color is Mylar, is it silver? No actually Mylar is not silver, Mylar is translucent. Mylar can be coated with a metalized film to make it appear silver. Mylar films come in many colors including white, black, silver, gold. blue, clear, brown, and other custom colors.
- Why do Mylar bags extend shelf life? Mylar slows and prevents the migration of oxygen and moisture through the bag, then control prevents things from drying out or getting soggy, which ensures peak freshness.
- Is Mylar safe? Properly sourced Mylar is very safe for food and doesn’t pose a health risk.
- Can You Print On A Mylar bag? Yes, you can print on a Mylar bag.
