Shrink films are commonly used in the packaging industry to wrap various products such as food items, pharmaceuticals, and consumer goods. One of the most advanced materials used in shrink film production is PETG, also known as PCTG.
PETG/PCTG is a high-performance copolyester that is produced by leading companies such as Eastman in the United States and SK Chemical in Korea. It is a top-of-the-line polymer material with excellent properties that make it suitable for use in shrink film applications.
One of the key advantages of PETG/PCTG is its exceptional clarity and gloss. This makes it perfect for use in packaging applications where appearance is important. The material is also highly resistant to impact, making it durable and able to withstand the rigors of transportation and handling. PETG/PCTG has excellent barrier properties that help to protect the contents inside the package from moisture, oxygen, and other contaminants.
Another advantage of PETG/PCTG is its ability to be easily printed on, which makes it ideal for branding and marketing purposes. The material has a good ink adhesion and can be printed on with a variety of printing technologies such as flexography, gravure, and digital printing.
In addition, PETG/PCTG has several environmental advantages over other materials. It is 100% recyclable and can be easily recycled into new products. It is also biocompatible, meaning that it can be used safely in direct contact with food and pharmaceuticals.
At Dawn Helf, we have developed proprietary technology for producing PETG/PCTG copolyester materials, filling a gap in the Chinese market for this high-performance material. Our PETG/PCTG products have passed FDA and other food contact certifications, making them suitable for use in food and pharmaceutical packaging applications.
Overall, PETG/PCTG is a versatile and high-performing material that has many advantages for use in shrink film applications. Its great clarity, durability, and environmental benefits make it an excellent choice for packaging products of all kinds.
