Three Y Flexible Packaging PLC manufactures advanced coffee and tea packaging films engineered to protect against oxygen, moisture, light, and aroma loss. Coffee and tea are highly sensitive products that require superior barrier performance to maintain freshness and flavor integrity throughout their shelf life.

Our packaging solutions are designed for roasted coffee, ground coffee, coffee powder, tea leaves, and tea blends. We provide multi-layer laminated films that ensure long-lasting aroma retention, structural durability, and premium shelf presentation.

🔹 Product Engineering & Development

Before production, our technical team carefully evaluates:

• Product type (roasted beans, ground coffee, tea leaves, tea dust)

• Aroma sensitivity level

• Shelf-life requirements

• Storage and transportation conditions

• Filling and sealing machine specifications

• Required barrier performance (oxygen & moisture protection)

Based on this analysis, we design optimized multi-layer structures using:

• PET (Polyester) for strength and print quality

• BOPP (Biaxially Oriented Polypropylene)

• PE (Polyethylene) for sealability

• CPP (Cast Polypropylene)

• Laminated combinations for enhanced barrier properties

Our goal is to ensure maximum aroma retention while maintaining strong sealing performance.

🔹 Step-by-Step Production Process

1. Raw Material Selection & Inspection

• Procurement of food-grade certified films

• Thickness and micron verification

• Surface smoothness and clarity inspection

• Roll uniformity and tension control

• Supplier compliance documentation review

Only approved materials proceed to the next stage.

2. Barrier Structure Engineering

• Oxygen transmission rate (OTR) analysis

• Moisture vapor transmission rate (MVTR) evaluation

• Shelf-life simulation planning

• Selection of appropriate laminated structure

This ensures optimal protection for aroma-sensitive products.

3. Artwork Preparation & Cylinder Engraving

• Professional color separation

• Design optimization for high-resolution printing

• Precision rotogravure cylinder engraving

• Pre-production sample proofing

• Client approval

4. Rotogravure Printing Process

• High-definition multi-color printing

• Ink adhesion monitoring

• Registration alignment control

• Continuous inline print inspection

This guarantees vibrant branding and long-lasting graphics.

5. Lamination Process

• Controlled adhesive application

• Pressure bonding of multi-layer films

• Temperature-regulated curing

• Lamination peel strength testing

This step enhances barrier performance and structural integrity.

6. Slitting & Conversion

• Precision roll width cutting

• Edge trimming and finishing

• Tension adjustment for machine compatibility

• Batch labeling and identification

7. Quality Control & Testing

Each batch undergoes strict verification:

• Seal strength testing

• Oxygen and moisture barrier testing

• Burst strength testing

• Lamination bond strength verification

• Thickness consistency check

• Visual inspection for defects

Only products that pass all quality tests are released for delivery.

🔹 Quality Assurance & Certification
