PE Film

Your Professional PE Film Supplier

 

 

PLA Shrink Film refers to a type of shrink film that is made from polylactic acid (PLA), a biodegradable polymer derived from renewable resources such as corn starch or sugarcane. PLA shrink film is widely used in packaging applications due to its environmental friendliness and ability to shrink tightly around products, providing secure and tamper-evident packaging.To facilitate seamless global transportation, the company maintains warehouses in Qingdao Free Trade Zone and Shanghai Free Trade Zone, situated near ports for convenient shipping worldwide.

Types of PE Film
 

Low-Density Polyethylene (LDPE) Film: LDPE is the most flexible and commonly used type of PE film. Its lightweight nature makes it perfect for applications like plastic bags, shrink wraps, and food packaging. The film offers excellent clarity, is easy to process, and has a high resistance to moisture.

 

High-Density Polyethylene (HDPE) Film: HDPE is much stronger and more rigid than LDPE, making it a preferred choice for more demanding packaging needs. This type of film is often used in applications where strength is a priority, such as heavy-duty industrial packaging, milk jugs, and detergent bottles.

 

Linear Low-Density Polyethylene (LLDPE) Film: LLDPE strikes a balance between the flexibility of LDPE and the strength of HDPE. It offers superior tensile strength and impact resistance, making it a preferred material for stretch films and heavy-duty liners.

 

Medium-Density Polyethylene (MDPE) Film: MDPE offers a middle ground between LDPE and HDPE, combining moderate strength and flexibility. It is often used for specific applications like carrier bags, and shrink wrap. While not as common as LDPE or HDPE, MDPE is useful when both flexibility and strength are required.

 

Advantages of PE Film

 

Good Transparency

PE film has excellent transparency, allowing ample light transmission and a favorable lighting environment. It is suitable for applications such as greenhouse covering materials and packaging.

Corrosion Resistance

PE film exhibits excellent corrosion resistance and is not easily corroded by chemicals such as acids, alkalis, and salts. Therefore, in certain special environments, PE film can act as a protective barrier, extending its lifespan.

Heat Resistance

It has high heat resistance and is capable of withstanding usage in high-temperature environments without melting or deformation. It is suitable for protective materials in high-temperature regions.

Cold Resistance

PE film demonstrates good cold resistance, maintaining flexibility even in frigid environments. It is suitable for freezer packaging.

Lightweight High Strength

It is a lightweight material with high strength, resisting easy breakage. It possesses a certain degree of toughness and elasticity, making it suitable for packaging and strapping applications.

Abrasion Resistance

The smooth surface of PE film is resistant to wear, ensuring a longer lifespan through good abrasion resistance.

 

 
 
PE Film Manufacturing Process

01.

Blown Film Extrusion (PE Blown Film)

In the PE blown film extrusion process, molten polyethylene resin is blown into a bubble and cooled by air. The bubble is then collapsed and formed into a continuous sheet. Blown PE film is highly durable and resistant to punctures, making it suitable for wrapping sharp or irregularly shaped loads. However, this PE blown film is more opaque compared to cast films and has a rougher texture. Its strength and elasticity make it ideal for heavy-duty packaging.

02.

Cast Film Extrusion

The cast film extrusion process involves forcing molten polymer through a slot die, which determines the film’s thickness. The film is then cooled on a roller, which creates a smooth and transparent material. Cast PE film is known for its clarity and consistent thickness, making it ideal for packaging products where visibility is important. It’s also quieter during application, which is a benefit in noise-sensitive environments like offices or retail spaces.

PE Film Properties
 

Lightweight: Despite its durability, PE film is remarkably lightweight. This helps reduce shipping and transportation costs while still providing sufficient protection for the goods.

 

Elasticity: PE film, especially LLDPE film and LDPE film, has a high level of elasticity. This means it can stretch and conform to the shape of the product, ensuring a secure wrap without the need for excessive material.

 

Transparency: Many types of PE film, particularly LDPE and cast films, are highly transparent. This allows easy identification of the packaged contents, which is an essential feature for retail and food packaging.

 

Chemical Resistance: One of the most valuable properties of polyethylene is its resistance to a wide range of chemicals. This makes PE film particularly useful in the packaging of industrial chemicals or products that need to be kept free from contamination.

 

Waterproofing: PE film is impermeable to water, making it an excellent choice for protecting products from moisture, whether it’s food items or goods being shipped in wet conditions.

 

Tear Resistance: HDPE and blown PE films are highly resistant to tears and punctures, even when subjected to sharp objects or rough handling. This durability is why PE film is often used for heavy-duty applications like pallet wrapping and protective covers.

Applications of PE Film
 

Packaging

PE film is commonly used for food packaging, shrink wraps, and stretch films, offering moisture resistance and transparency. It is also a popular choice for consumer goods and industrial packaging, helping to secure products during shipping and storage.

 

Agriculture

In agriculture, PE film is used for greenhouse covers, mulch films, and silage wraps. These films enhance crop growth, control soil conditions, and protect fodder, helping farmers achieve better yields while reducing water and herbicide use.

 

Construction

PE film acts as a moisture barrier in buildings and serves as protective sheeting for surfaces during construction. It also forms temporary enclosures on job sites, protecting equipment and workers from environmental factors.

 

Healthcare

PE film is vital in medical packaging, providing a sterile barrier for equipment and supplies. It is also used to make disposable healthcare products like gloves, gowns, and drapes due to its liquid-resistant properties.

 

Industrial applications

PE film serves in industrial settings for protective packaging of machinery and as a release film in manufacturing processes. It safeguards components and ensures efficient production.

 

Retail and E-commerce

PE film is essential in e-commerce, used in mailing bags and protective covers for electronics. Its durability ensures items are protected during transport, making it indispensable for online retail.

 

FAQ

Q: What are the advantages of polyethylene poly film?

A: Product developers choose PE because it is versatile and durable, resistant to impact and chemicals, features low moisture absorption, and doesn't retain bacteria.
