Horizontal tension and pressure keeps the metal flat and still as the rollers press the metal. Mylar is actually not a form of metal at all.

Melinex and Hostaphan are two other well-known trade names for this plastic, which is more generally known as BoPET or biaxially-oriented polyethylene terephthalate. The Echo balloon was 40 meters in diameter and constructed of 9 micrometers thick Mylar film sandwiched between layers of 4.

Mylar and other BoPET films are used to make flexible packaging and lids for the food industry, such as yogurt lids, roasting bags, and coffee foil pouches. BoPET is used to package comic books and for archival storage of documents. It's used as a covering over paper and cloth to provide a shiny surface and protective coating. Mylar is used as an electrical and thermal insulator, reflective material, and decoration.

It's found in musical instruments, transparency film, and kites, among other items. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert. Helmenstine holds a Ph. She has taught science courses at the high school, college, and graduate levels. Facebook Facebook Twitter Twitter. Molten polyethylene terephthalate PET is extruded as a thin film onto a chilled surface, such as a roller.

The film is drawn biaxially. Special machinery may be used to draw the film in both directions at once. More commonly, the film is drawn first in one direction and then in the transverse orthogonal direction. Heated rollers are effective for achieving this.

Rubber elasticity

A pure film is so smooth it sticks to itself when rolled, so inorganic particles may be embedded in the surface.

Vapor deposition may be used to evaporate gold, aluminum or another metal onto the plastic.A former cake decorator and competitive horticulturist, Amelia Allonsy is most at home in the kitchen or with her hands in the dirt.

Helium balloons are a common decoration for all types of parties.

They float in the air, which allows for greater decorative versatility than air-inflated balloons that simply scatter on the ground. You can purchase inflated helium balloons or rent an inflation kit that allows you to blow them up right before the party for a longer-lasting decoration.

The main problem with helium balloons is that the helium loses its efficacy over a period of time, resulting in deflated balloons or balloons that won't stay in the air.

There are steps you can take to extend the length of helium balloons.

Inflate the balloons with air first, deflate them and then inflate with helium. By inflating the balloons with air first, you will stretch the balloon, which ensures that you are getting maximum helium coverage when it's time to inflate with helium. Store inflated balloons in a trash bag before and after use to protect from sunlight, dirt and wind. Oxygen will also corrode the balloon material, so the trash bag will help to protect it from oxygen damage.

Coat the inside of the balloon with Super Hi-Float gel and allow to dry before inflating. This gel is known to increase the length of helium balloons by several weeks. Spray the outside of the balloon with a protective coat to prevent oxidization, a major factor in balloon deterioration. You can use a product such as Hi-Float or a household product like hairspray to firm and seal the surface.

Inflate the balloons in an environment similar to the temperature where they will be used. If you are going to use the balloons in a warm room, inflate them in a room of about the same temperature to reduce the impact of expansion and deflation caused by temperature change. Use lighter colored balloons in place of dark balloons whenever possible. Light colors reflect light and heat, while dark colors absorb light and heat, increasing the risk of fading and deflation.

If possible, rent a helium tank and inflate the balloons on the day of the party to ensure that the helium is fresh inside the balloons.
