Petrolatum jelly products (such as petroleum jelly and medicated jelly) require specialized packaging due to their oil-based composition, semi-solid texture, and sensitivity to contamination. Our Petrolatum Jelly Flexible Packaging Wrappers are designed to provide superior oil resistance, strong sealing integrity, and high barrier protection to maintain product purity and stability.

These wrappers are suitable for:

• Petroleum jelly sachets

• Medicated petrolatum products

• Cosmetic-grade petroleum jelly

• Sample-size travel packs

• Pharmaceutical petrolatum applications

• Bulk refill packaging

Because petrolatum is oil-rich and can migrate into low-quality films, we use carefully engineered multilayer laminates to prevent leakage, grease penetration, and packaging deformation.

🏭 Step-by-Step Production Process

1. Raw Material Selection & Oil Compatibility Testing

Petrolatum jelly is highly oil-based, which means ordinary packaging films can weaken or delaminate over time. We use multilayer structures such as:

• PET / PE

• BOPP / CPP

• PET / Aluminum Foil / PE

• Nylon / PE laminates

Each material undergoes:

• Oil migration testing

• Heat resistance testing

• Chemical stability evaluation

• Seal strength validation

This ensures the packaging remains stable even in warm climates and during transportation.

2. Product & Packaging Engineering Design

Our team works with clients to determine:

• Sachet size and thickness

• Required barrier level

• Seal type (3-side seal, 4-side seal, pillow pack)

• Shelf-life requirements

• Regulatory labeling compliance

We also ensure that the packaging supports easy tearing and consumer convenience.

3. High-Resolution Printing

We apply advanced rotogravure or flexographic printing to achieve:

• Clear medical-grade labeling

• Premium cosmetic branding

• Smudge-resistant surface

• Fade-resistant ink

• Oil-resistant ink adhesion

All inks used are non-toxic and compliant with pharmaceutical and cosmetic packaging standards.

4. Lamination & Barrier Protection

The printed films are laminated using high-performance adhesive systems. This step:

• Enhances oil resistance

• Strengthens mechanical durability

• Improves puncture resistance

• Prevents leakage

• Protects from oxygen and moisture

Bond strength is tested to ensure the layers remain intact throughout the product lifecycle.

5. Slitting & Conversion

After lamination:

• Rolls are slitted into precise widths

• Converted into sachets or roll stock

• Heat-sealed using temperature-controlled equipment

Seal strength is critically important for petrolatum packaging to prevent leakage in high-temperature environments.

6. Strict Quality Control Testing

Each production batch undergoes:

• Oil penetration testing

• Seal integrity testing

• Burst strength testing

• Drop testing

• Thickness and GSM measurement

• Visual inspection for defects

• Migration and compliance checks

We ensure every package meets safety, hygiene, and durability standards.

🛡 Quality Assurance & Compliance

Our manufacturing process follows strict hygiene and safety standards suitable for cosmetic and pharmaceutical packaging applications. We ensure:

• Non-toxic material usage

• Controlled production environment

• Batch traceability

• Consistent barrier performance

• Leak-proof reliability

This makes our packaging ideal for both domestic and export markets.
