What are the composition and properties of PE coated paper?
PE coated paper combines the structural integrity of paper with the protective qualities of polyethylene, creating a versatile packaging material used across multiple industries.
Manufacturing process of PE coated paper
Two primary methods are used to create PE coated paper:
- Extrusion Coating: Molten polyethylene is applied directly to the paper surface as it passes through specialized machinery, creating a strong bond between the paper and coating.
- Lamination Process: Pre-formed PE film is pressed onto paper under controlled heat and pressure, resulting in a secure adhesion between layers.
Composition of PE coated paper
| Component | Function | Characteristics |
|---|---|---|
| Base Paper | Provides structure and stability | Typically kraft, white, or bamboo-based |
| PE Coating | Delivers protective barrier | Usually LDPE, thickness 10-20 GSM |
Properties of PE coated paper
PE coated paper offers multiple performance advantages:
- Water resistance: Creates an effective barrier against moisture, preventing the paper from becoming soggy

Moisture Resistance Advantage
PE coating creates a near-impermeable barrier against water, preventing paper from becoming soggy or deteriorating when exposed to liquids. At just 10 GSM coating thickness, PE coated paper provides sufficient waterproofing for most applications.
Protection from Oils and Grease
The polyethylene layer effectively blocks oils and greases from penetrating the paper structure, keeping exteriors clean and preventing staining—crucial for food service packaging.
Additional Performance Benefits
- Heat sealability: Enables secure package closure without adhesives
- Chemical inertness: Remains stable when contacting various substances, making it food-safe
- Flexibility: Maintains structural integrity while allowing easy folding and shaping
- Branding excellence: Supports high-quality printing for vibrant logos and marketing messages
What are the disadvantages of using PE coated paper?
While PE coated paper offers numerous benefits, it also comes with several limitations that manufacturers and consumers should consider before choosing this material for their applications.
Key Limitations of PE Coated Paper
- Gas Permeability Issues: Despite excellent moisture resistance, PE coating offers poor oxygen barrier properties, making it unsuitable for long-term food preservation
- Odor Transmission: The coating allows odors to pass through, potentially affecting product quality and user experience
- Temperature Sensitivity: Limited heat resistance (80-100°C), restricting use in microwave and high-temperature applications
Environmental Challenges
| Challenge | Description | Impact |
|---|---|---|
| Recycling Complexity | Requires specialized hydro pulping to separate PE from paper | Increases recycling costs and reduces recovery rates |
| Non-biodegradable Nature | PE coating persists in the environment for hundreds of years | Contributes to long-term environmental pollution |
| Fossil Fuel Dependency | Production requires petroleum-derived resources | Increases carbon footprint and resource depletion |
Practical Considerations
- Production & Processing Challenges:
- Difficulty in printing without special treatments or inks
- Requires specialized equipment for manufacturing and processing
- More expensive than uncoated paper alternatives
- Sustainability Concerns:
- Not compostable in standard facilities
- Contributes to plastic waste accumulation
- Challenging to incorporate into circular economy models
How does PE coated paper compare with other types of coated and uncoated papers?
Comparative Analysis of Paper Types
| Performance Factor | PE Coated Paper | Wax Coated Paper | Clay Coated Paper | Uncoated Paper |
|---|---|---|---|---|
| Water Resistance | Excellent | Good | Poor to Moderate | Poor |
| Grease Resistance | Excellent | Good | Poor | Poor |
| Structural Integrity | High | Moderate | Moderate | Low |
| Printability | Good (requires special inks) | Limited | Excellent | Very Good |
Water and Moisture Resistance
PE coated paper significantly outperforms other options in moisture protection. While uncoated paper absorbs water immediately and loses structural integrity, PE coating creates a nearly impermeable barrier that maintains the paper's form and function even when exposed to liquids.
Grease and Oil Resistance
- PE coated paper: Prevents oil penetration completely
- Wax coated paper: Provides temporary resistance
- Clay coated/Uncoated: Quickly absorbs oils, causing staining
Structural Integrity Benefits
PE coating enhances paper's durability by:
- Preventing fiber separation when wet
- Adding tensile strength
- Improving tear resistance
- Maintaining shape under stress
Printing Capabilities Comparison
Though PE coating presents some printing challenges compared to clay-coated papers, modern printing technologies have largely overcome these limitations. While uncoated papers offer excellent ink absorption, they lack the protective qualities essential for many applications.
What are the quality control and testing methods for PE coated paper?
Ensuring PE coated paper meets strict quality standards is essential for maintaining product integrity across various applications. Comprehensive quality assurance protocols safeguard both performance and safety.
Quality Control Process Flow
Quality assurance for PE coated paper follows a systematic approach:
- Raw Material Inspection
- Verification of paper base quality (tears, wrinkles, contaminants)
- PE resin testing for molecular weight and melt flow index
- Additive quality assessment for consistency
- Process Control Measures
- Continuous monitoring of extrusion temperature profiles
- Coating weight measurement and adjustment
- Adhesion parameters verification during production
- Finished Product Inspection
- Visual examination for coating uniformity
- Dimensional stability checks
- Surface quality assessment
Critical Testing Methods
| Test Type | Procedure | Acceptance Criteria |
|---|---|---|
| Water Resistance | Sample submersion for specified time period | No penetration, minimal softening |
| Grease Resistance | Application of standardized oils at controlled temperatures | No staining or penetration after set period |
| Tensile Strength | Controlled force application until material failure | Meets minimum strength requirements |
Regulatory Framework
PE coated paper must adhere to multiple regulatory standards:
- FDA Regulations: Materials must be food-safe with approved additives for food contact applications
- ASTM Standards: ASTM D6868 for compostability; ASTM F119-82 for steam resistance
- European Regulations: EU 10/2011 on plastic materials contacting food; EFSA guidelines on migration limits
Is PE coated paper safe?
Yes, PE coated paper is safe for food contact. Polyethylene is chemically inert and doesn't react with food or alter flavor. Manufacturers must pass rigorous FDA and EU certification processes before their products can be used for food packaging applications.
Is PE coated paper recyclable?
PE coated paper is technically recyclable but requires specialized processing:
- Requires hydro pulping to separate PE coating from paper fibers
- More complex and expensive than standard paper recycling
- Not accepted in all recycling programs
- Check local recycling guidelines before disposal
What is the difference between single-side and double-side PE coated paper?
| Feature | Single-Side PE Coated | Double-Side PE Coated |
|---|---|---|
| Coating Location | One side only | Both sides |
| Primary Uses | Hot beverage cups, burger wrappers | Cold drinks, ice cream containers |
| Moisture Protection | Internal only | Both internal and external |
| Condensation Handling | Limited | Excellent |
| Cost | Lower | Higher |
Can PE coated paper be used in the microwave?
No, PE coated paper is not microwave-safe. The coating has low temperature resistance (80-100°C) and may release potentially harmful substances when heated beyond this threshold.
How does the thickness of the PE coating affect the paper's properties?
Coating thickness (measured in GSM) directly impacts functionality:
- 10 GSM: Basic water/moisture resistance
- 12-15 GSM: Suitable for adhesive applications
- 18-20 GSM: Optimal for heat-sealing capabilities
What is PE-lined paper?
PE-lined paper is another term for PE coated paper. Both refer to paper with a polyethylene layer applied to one or both surfaces to enhance water resistance and other protective properties.
Is PE coated paper biodegradable?
No, PE coated paper is not biodegradable. While the paper substrate would naturally decompose, the polyethylene coating persists in the environment for hundreds of years. For eco-friendly alternatives, consider papers with PLA or other biodegradable coatings.
