Q1: What is PET material?
PET (also abbreviated PETE) is short for polyethylene terephthalate, the chemical name for polyester. The basic building blocks of PET are ethylene glycol and terephthalic acid, which are combined to form a polymer chain. The resulting spaghetti-like strands of PET are extruded, quickly cooled, and cut into small pellets. The resin pellets are then heated to a molten liquid that can be easily extruded or molded into items of practically any shape.
PET was first synthesized in North America in the mid-1940s by DuPont chemists searching for new synthetic fibers. DuPont later branded its PET fiber as "Dacron." Today, more than half of the world's synthetic fiber is made from PET, which is called "polyester" when used for fiber or fabric applications. When used for containers and other purposes, it is called PET or PET resin.
Q2: What is mylar paper?
Mylar paper is paper that is coated with or made from a polyester film BoPET (Biaxially-oriented polyethylene terephthalate). Mylar isn’t the polyester film itself but the brand of BoPET manufactured in the United States and the UK. Mylar is durable and has a high tensile strength; meaning it can be stretched for a long period of time without breaking. Its reflective and transparent nature make it a great accent for decorative projects as well as many other practical uses.
Q3: What is PET coating?
Coated PET film
PET coating, also called coated PET film, is a plastic film that has been coated with material on one or two sides of the film. The type and amount of coating applied to determine the physical, mechanical, optical, thermal, electrical and chemical properties. Coated films may also be a combination of coatings and treatments, such as coating one side / treating the other side depending on end-use application requirements.
Q4: How many types of PET film are there?
• PET high-gloss glossy film
• PET film
• PET transfer film
• PET Reflective Film
• PET chemical coated film
• PET anti-static film
• PET Heat Seal Film
• PET heat shrink film
Q5: Can you print on PET film?
There are many different grades of polyester film, and some are produced specifically to be printable, using specific methods particular to those film’s chemical properties. Firsta has a number of specific polyester film solutions for many different printing methods, both conventional and digital. If you’re looking for laser-printable or inkjet-printable films, please check out our product page.
Q6: What is PET film used for?
PET film is often an excellent choice for more demanding applications in food and nonfood-film applications. Major uses include microwave, and medical packaging, plastic wrap, tape backing, printed films, plastic cards, protective coatings such as solar and safety window films, release films, transformer insulation films and flexible printed circuits. PET is also used as an aroma barrier film (e.g. coffee and tobacco packaging). This type of film is sometimes metalized by vapor deposition of metals, which further improves the barrier against oxygen, water vapor and aroma loss.
Due to the low odor, high chemical resistance and inertness, many PET grades are suitable for packaging applications under FDA regulations.
Polyester film is sold in various types, thicknesses, widths with properties tailored to meet specific requirements of particular end uses.
Q7: What is the difference between BOPET(BOPP) and PET?
Coated BOPP film
BOPET(BOPP) film literally means biaxially stretched polyester film, and PET means polyester chips, which are divided into three categories, large bright polyester chips, full matte polyester chips, semi-matte polyester chips, these three It is the raw material for the production of polyester film (PET film). BOPET film and PET film can be said to have no difference because the production process of PET film is bidirectional stretching, which is the industry standard for BOPET film.
Q8: Is PET a moisture barrier?
PET commonly is used for water bottles, but also is FDA-approved for food packaging, so it can be used to create some clamshell packaging. It provides strong moisture resistance and it’s a strong, shatterproof plastic and an affordable option as well.
