Choose TRADSARK for Premium Films—Long-lasting Protection, Doubled Benefits

CPE films, also known as cast PE film or cast polyethylene film, made of polyethylene as the primary material, are formed through a casting process. This film-making technology uses molten polymer extruded through a hole of a die and cooled on a cooling roller to form a film. Unlike the blow molding process, the casting process uses higher temperatures, which results in faster production speeds, better film strength, and elongation. Our cast polyethylene products are widely applied in diverse areas, including food packaging, drug packaging, and construction supplies. With our wide experience and expertise, we can provide the cast films of different types you require. CPE films are known for their high strength, high transparency, and excellent sealing features, which make them particularly popular in the food packaging industry. They keep food safe from moisture and oxygen, yielding a clear visual display. Furthermore, CPE films are widely used in pharmaceutical packaging, where these non-toxic and odorless properties ensure drug safety. The BOPE/CPE composite structure has a unique monoolefine structure, which makes it recommended for applications requiring high strength, weather resistance, and barrier properties. Functional requirements of CPE combined with other plastic films, including nylon, PET, and BOPP, are also possible. Tradsark was established in 2016 and is now one of the largest suppliers of cast polyethylene film (CPE) in China. We have six major warehouses nationwide, allowing us to process big orders and deliver them quickly.

PE Film: Features and Advantages

PE film is produced using polyethylene resin, which can be processed through various techniques such as casting and extrusion to achieve different types of films. It can be produced in different thicknesses and grades, depending on the intended application. This film is lightweight yet durable, offering significant flexibility, moisture resistance, and excellent sealing properties.

Key Advantages of PE Film:

  • Excellent Barrier Properties: PE film effectively blocks moisture, dust, and contaminants, ensuring the freshness and longevity of packaged products.

  • High Flexibility: Offers flexibility to adapt to different product shapes and sizes, making it ideal for various packaging applications.

  • Durability and Strength: Resistant to tears, punctures, and physical damage, ensuring that products remain intact during transportation and storage.

  • Transparency: Provides high clarity, making it perfect for showcasing the product inside, enhancing visual appeal for consumers.

  • Environmentally Friendly Options: Available in recyclable and biodegradable variants, PE film supports eco-conscious packaging practices.


Key Applications of PE Film

PE film’s broad range of applications showcases its importance in many industries. Here’s how PE film is used across different sectors:

Food Packaging

PE film is widely used in food packaging to extend shelf life, maintain freshness, and protect food from external contaminants. Its ability to act as a moisture and oxygen barrier helps preserve the product’s quality for longer periods. Common applications include:

  • Fresh Produce Packaging: Protects fruits, vegetables, and herbs from moisture and bacteria.

  • Snack Packaging: Provides a durable seal for snack bags, preventing air and moisture from affecting the contents.

  • Frozen Foods: Keeps frozen foods protected from environmental factors while maintaining visibility.

Pharmaceutical Packaging

PE film plays a critical role in the safe packaging of drugs and medical devices, offering essential protection from moisture, dust, and other contaminants. It ensures the integrity and safety of the pharmaceutical products, keeping them in a sealed, sterile environment.

Agricultural Uses

In the agriculture industry, PE film is used as a protective covering for crops, preventing exposure to harmful environmental factors such as extreme weather, pests, and diseases. It is especially valuable for greenhouse films and crop protection sheets.

Industrial Product Packaging

PE films are commonly used to package various industrial components and products to protect them from physical damage. Whether used for packaging machinery parts, components, or hardware, PE film ensures durability and maintains product quality during handling and transportation.

Consumer Electronics Packaging

PE film provides protection for electronic devices and accessories by offering anti-static properties, moisture protection, and durability. It is widely used for packaging mobile phones, laptops, and other sensitive electronic products, ensuring they remain safe during shipping.

Household Goods Packaging

PE film is used for packaging a wide variety of household items and consumer goods, such as cleaning agents, toiletries, and personal care products. The film’s resistance to moisture, dust, and contamination helps maintain the integrity of these products during storage and transport.
