At present, high barrier and multi-functional films are developing to a new technical level. As for functional film, because of its special function, it can better meet the requirements of commodity packaging, or better meet the needs of commodity convenience, so the effect is better and more competitive in the market. Here, we will focus on BOPP and PET films
BOPP, or Biaxially Oriented Polypropylene, is a widely used plastic film in packaging and labeling. It undergoes a biaxial orientation process, enhancing its clarity, strength, and printability. Known for its versatility, BOPP is commonly used in flexible packaging, labels, adhesive tapes, and lamination applications. It offers excellent product visibility, durability, and is recyclable, making it a popular choice for various packaging needs.
PET, or Polyethylene Terephthalate, is a widely used thermoplastic polymer known for its versatility and clarity. Commonly used in the production of plastic bottles for beverages, food containers, and packaging, PET is transparent and has excellent barrier properties against oxygen and moisture. It is lightweight, durable, and recyclable, making it a popular choice for various packaging applications. Additionally, PET is used in fibers for clothing, as well as in the manufacturing of films and sheets for diverse purposes.
Difference
PET stands for polyethylene terephthalate, while BOPP stands for biaxially oriented polypropylene. PET and BOPP films are thin plastic films most commonly used for packaging. Both are popular choices for food packaging and other applications, such as product labels and protective wraps.
Regarding the differences between PET and BOPP films, the most obvious difference is the cost. PET film tends to be more expensive than BOPP film due to its superior strength and barrier properties. While BOPP film is more cost-effective, it does not provide the same protection or barrier properties as PET film.
In addition to cost, there are differences in temperature resistance between the two types of film. PET film has a higher melting point than BOPP film, so it can withstand higher temperatures without warping or shrinking. BOPP film is more resistant to moisture, so it can protect products that are sensitive to moisture.
Regarding the optical properties of PET and BOPP films, PET film has superior clarity and gloss, while BOPP film has a matte finish. PET film is the better choice if you’re looking for a film that offers excellent optical properties.
PET and BOPP films are made from plastic resins but contain different materials. PET comprises polyethylene terephthalate, combining two monomers, ethylene glycol, and terephthalic acid. This combination creates a robust and lightweight material highly resistant to heat, chemicals, and solvents. On the other hand, BOPP film is made from biaxially-oriented polypropylene, a combination of polypropylene and other synthetic components. This material is also strong and lightweight but less resistant to heat and chemicals.
The two materials have many similarities in terms of physical properties. Both are highly transparent and have excellent clarity, making them ideal for applications that require a clear view of the contents. Additionally, both materials are solid and flexible, making them suitable for various applications.
However, there are some key differences. PET is more rigid than BOPP film and is less susceptible to tearing or puncturing. PET has a higher melting point and is more resistant to UV radiation. On the other hand, BOPP film is more malleable and can be stretched and shaped to fit various applications.
summary
In conclusion, pet film and Bopp film have their differences. PET film is a polyethylene terephthalate film, making it a thermoplastic that can be heated and shaped without losing its structural integrity. It has excellent dimensional stability, optical properties, and chemical resistance, making it a great choice for many applications. The Bopp film, on the other hand, is a biaxially-oriented polypropylene film. It is a lightweight yet strong material with excellent optical, mechanical, and thermal properties. It is beneficial in applications where high clarity and superior strength are needed.
When choosing between these two films, it is essential to consider the application. PET film is ideal for applications that require a great deal of dimensional stability and chemical resistance. Bopp film is more suitable for applications that require high clarity and superior strength.
We hope this blog has helped you better understand the differences between pet and Bopp films and choose the one that best suits your application.
