Understand PE Coated Paper: Application And Future

In the wide application of modern packaging materials, PE coated paper was once favored by the market as a recognized environmentally friendly material and its superior performance. Whether it is to maintain the freshness of food, prevent liquid leakage, or provide product durability and easy-to-clean surfaces, PE coated paper can meet diverse needs. In this article, we will have an in-depth understanding of PE coated paper. Before understanding the characteristics, application fields and future development trends, we will first understand the basic information of the product.

Let's get started!

In daily life, everyone knows that paper absorbs moisture and is afraid of moisture. Why can the disposable paper cups and bowls we use can hold liquids without leaking?

This is because ordinary paper is made of wood fiber and has strong water absorption, while paper cups are made of moisture-resistant and anti-penetration PE-coated paper.

This coating enhances the paper's properties, making it more resistant to moisture, grease and other liquids. The PE coating forms a barrier that prevents liquids from penetrating the paper fibers, making it ideal for packaging and moisture and grease resistant applications. The paper bags, hamburger paper bags, melon seed bags, paper lunch boxes, food paper bags, and aviation garbage bags we see in our daily life are all made of this material.

Assume we put a paper cup in the alcohol and soak it for 3-5 minutes, after the paper fibers get soft, we can separate a thin LDPE film out.

Processing
In its processing, a laminating machine is used to hot-melt LDPE plastic particles and evenly coat them on the surface of the paper to form a very thin film. The two are firmly combined and difficult to separate. The entire process does not use any chemical solvents and is very environmentally friendly.

By type, the market is segmented into High-density Polyethylene (HDPE),Medium-density Polyethylene (MDPE), Low-density Polyethylene (LDPE), and Linear Low-density Polyethylene (LLDPE).

Amongst these, the HDPE segment holds the largest polyethylene market share owing to its characteristics such as low manufacturing cost, high strength-to-density ratio, and high-temperature resistance.

HDPE is highly resistant to various types of solvents and has a wide variety oapplications such as bottle caps, ballistic plates, food storage containers,and others.

LDPE is mainly used in food packaging industry due to its chemical resistance, flexibility, and softness. The rising demand for lightweight packaging in electronics, healthcare, and food &beverages is further surging the demand for LDPE in the market.

LLDPE has a structure similar to that of LDPE. The former is used to produce a wide range of products. lt is usually processed unaccompanied or blended with LDPE and HDPE. The properties of LLDPE, such as high tensile strength, high impact resistance, and flexibility,make it suitable for packaging, agriculture, healthcare, and construction industries.

Its processing raw material PE stands for polyethylene, which is odorless, non-toxic and waxy. It is the safest chemical in food processing.

PE paper cups are covered with a layer of PE lamination on the inside of the cup, which is waterproof and oil-proof in most circumstances. Its melting point is between 120° - 140°, so it does not dissolve in boiled water and is safer to use.
It does not cause any damage in contact with the skin. However, if an unexpected allergic reaction occurs, consult a doctor.

Good water resistance and grease resistance

The PE coating forms a barrier to effectively prevent liquids from penetrating the paper fibers, preventing the paper from becoming wet and soft, food staining and contamination. Making it ideal for packaging and moisture and grease resistant applications such as baked, fried, frozen and fast food products. Coating thickness can be customized according to usage. Its waterproof capabilities make it one of the most popular food wrappers on the market.
 

Good heat sealing capability

PE coated paper has heat sealability, and the heat sealer can remelt the plastic and seal the package. Provides a secure, air-tight seal that helps preserve food nutrients and flavor. Heat sealing also provides tamper-proof packaging to ensure food safety.

Good Chemical Stability

PE Coating Has Good Chemical Stability And Will Not React With Food Or Other Substances It Comes Into Contact With.
 

Durability

The combination of PE coating and paper not only improves the strength and stiffness of the paper material, but also gives it strong tear resistance. Make it meet most usage requirements in the packaging industry.
 

Printability PE
coated paper has excellent printability and waterproofness, which can improve printing quality and effect. It is used to produce various printed materials such as brochures, posters and magazines.

• Chemical industry: desiccant packaging, preservatives
• Food categories: bread bags, hamburger packaging, melon seed bags, sugar packaging, coffee packaging bags
• Paper: Copper paper packaging, light coated paper packaging, copy paper (neutral paper)
• Lifestyle categories: salt packaging, disposable paper cups, paper bowls
• Medical and sanitary material packaging: medical equipment packaging, traditional Chinese medicine packaging, pesticide packaging
• Other categories: aviation garbage bags, disposable travel supplies, 3C electronic low-viscosity protection field, copper-clad laminate outer packaging, silicon-coated release paper

The global PE coated paper market value in 2020 is US$18.7 billion, showing a year-by-year growth trend. It is expected that by the end of 2031, the global PE coated paper market value will exceed US$29.9 billion.

Main production capacity distribution areas:
North America: United States, Canada, Mexico
Europe: UK, Germany, France, Italy, Spain
Asia-Pacific: China, Japan, India, ASEAN, Australia
Latin America: Brazil, Argentina
Middle East and Africa: Saudi Arabia, United Arab Emirates, Nigeria, South Africa

As one of the origins of PE coated paper - China. The demand for PE coated paper has continued to grow since 2013. In 2021, the demand for laminated paper reached a new high in recent years, and then dropped slightly to 4.85 million tons in 2022.

From a supply perspective, China's PE coated paper production in 2022 will be approximately 5.19 million tons amid factors such as export obstruction and demand fluctuations.
