What is PET Film products used for?
Jul 24, 2023|
View:2205PET film products are widely used in various industries and applications due to their versatility and popularity. This is a strong, flexible and transparent type of plastic, known as polyethylene terephthalate (PET), used to make many types of films, including packaging films, protective films and display films.
We have met the needs of our clients with quality PET film products. We build and supply durable, flexible, and high-performance products used in many applications.
1.What is PET Film?
PET(Polyethylene terephthalate) film also known as a polyester-based polymer material which is produced by the process of biaxial orientation(Biaxially Oriented PET, are called BOPET) It consists of straight-chain and rigid phenylene groups, polar ester groups, and flexible aliphatic hydrocarbon groups. This gives PET film its characteristic strength and dimensional stability. In 2024, the global PET film market size was 24.5 billion US dollars according to data from Smithers, a global market research institution. Among them, more than 45% came from the Asia-Pacific region and accounted for 60% of the production capacity in the world with China as the world's largest producer.
2.The Properties of PET films
PET film is a kind of synthetic polymer, with excellent characteristics of a variety of excellent materials. First of all, it has very strong mechanical properties, with good tensile strength and tear resistance, which can withstand a relatively large external force and is not easy to damage. Second PET film transparency and gloss enough can effectively improve the appearance texture of products. PET film is also very excellent in heat resistance, chemical corrosion resistance and barrier properties. It can reserve the properties to hinder substances like oxygen and water vapor from penetrating, and prolong the shelf life of the products.
The following are some detailed properties of PET film:
Mechanical Properties: The tensile strength can reach 200-300MPa (glass fiber reinforced type), the impact strength is 3 to 5 times that of PVC film, the flexural modulus is 4000MPa, and it can withstand extreme temperatures ranging from -70°C to 150°C.
Barrier Properties: The water vapor transmission rate is ≤ 3g/m²·24h, and the oxygen transmission rate is ≤ 5cm³/m²·24h·0.1MPa, which is comparable to the protective performance of aluminum foil composite materials.
Optical Properties: The light transmittance is > 90%, and the haze is < 1.5%, making it suitable for optical precision fields such as the reflective film of liquid crystal display screens.
Safety Certifications: It has passed food contact material certifications such as FDA and EU 10/2011, and the migration amount of heavy metals is < 0.01ppm.
3.Advantages of PET film products
One of the key benefits of PET film products is their versatility. They can be manufactured in a wide range of thicknesses, widths, and lengths, catering to diverse applications from food packaging to industrial uses. Additional advantages include:
Moisture and Chemical Resistance: PET films are highly resistant to moisture, chemicals, and UV radiation, making them an ideal choice for products requiring high levels of protection and durability.
Customization: PET films can be tailored to specific requirements, including coatings and finishes that enhance their functionality.
There are several types of PET films available, each with its own unique properties and applications.
Common Types of PET Films
Packaging Films: Ideal for food, beverages, and consumer goods.
Protective Films: Designed to safeguard surfaces from scratches and abrasions.
Display Films: Used in electronic displays and touch screens requiring high clarity.
Lamination Films: Strengthen and enhance durability by bonding materials.
Release Films: Facilitate the easy release of adhesives and other materials.
4.Application of PET film products
PET film products are incredibly versatile and can be used in a wide range of applications. Some of the most common applications of PET film products include:
Packaging - PET films are commonly used in food packaging, beverage packaging, and other consumer goods.
Industrial applications - PET films are used in a variety of industrial applications, including insulation, electrical components, and automotive parts.
Displays - PET films are used in electronic displays, touch screens, and other applications that require high levels of clarity and resolution.
Labels and decals - PET films are commonly used for product labels, decals, and other branding materials.
Protective films - PET films are used to protect surfaces from scratches, abrasions, and other damage.
5. Precautions for Customizing PET Film Products
When customizing PET film products, consider several critical factors:
Type and Thickness: Choose the appropriate type and thickness based on your application needs.
Desired Protection Level: Assess the environmental conditions and required durability.
Application Requirements: Collaborate with an experienced supplier to ensure the film meets specific requirements and standards.
6.Summarize
