Metallized boPET film, 32 layers of ~14 μm thickness each. BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation.

Mylar balloons can cause headaches for linemen in a couple of scenarios: They can get caught between and make contact with wires, or they can float directly into transformers. A cluster of ...
The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil. This gives metallised films some advantages over aluminium foil and aluminium foil laminates.
Decoys such as mylar balloons that can be inflated in space and are designed to have the same radar characteristics as the warhead. As the warhead and the decoy balloons may be at different temperatures, the warhead and the balloons may both be surrounded by heated shrouds that put them all at the same temperature.
Mylar and paper balloons are far safer than latex balloons. Stay current on Infant and Child First Aid and CPR — the life you save may be very dear to you. Ultimately, McGloghlon hopes that by ...
Feb. 12—The Public Service Company of New Mexico has released a reminder to keep Mylar balloons away from power lines this Valentine's Day. "Mylar balloons are made of metallic materials that ...
The balloon law prohibits the sale or distribution of a balloon that is constructed of electrically conductive material (metallized Mylar or foil) and filled with a gas lighter than air (helium), without affixing an object of sufficient weight to the balloon to counter the lift capability, affixing a specified warning statement on the balloon ...
Perhaps counterintuitively, the surface area of the inflated balloon is less than the surface area of the circular sheets. This is due to physical crimping of the surface, which increases near the rim. "Mylar balloon" is the name for the figure given by W. Paulson, who first investigated the shape. The term was subsequently adopted by other ...
