Customer Requirement

Why Petroleum Jelly / Vaseline Gel Needs a Dedicated Sachet Packing Solution

Petroleum jelly, also known as petrolatum gel or Vaseline gel, is different from ordinary liquid products. It has higher viscosity and does not flow as smoothly as water-based liquid. During high-speed sachet packaging, the main challenges are:

1. Stable 5g dosing accuracy
   Petroleum jelly can create resistance during filling. A piston pump is more suitable than a simple liquid pump because it can push viscous gel more consistently into each lane.

2. Clean sealing area
   If gel sticks to the sealing area, it may cause weak sealing, leakage or dirty sachet edges. The filling nozzle and sealing timing must be coordinated to reduce product contamination around the seal.

3. Reliable heat sealing for composite film
   Cosmetic sachets often require good appearance and leak resistance. For this project, the machine was designed with 5mm vertical sealing and 5mm horizontal sealing, helping maintain stable seal strength.

4. Small sachet forming stability
   The sachet width is only 42mm, so film tracking, lane alignment and cutting precision are important for finished sachet appearance.

Machine Solution: SF720Y-5 5-Lane Liquid Sachet Packaging Machine

For this Netherlands petroleum jelly project, Samfull selected the SF720Y-5 5-lane liquid sachet packing machine. The machine uses roll film to automatically complete:

• Film unwinding

• Multi-lane film splitting

• Sachet forming

• Piston pump dosing

• Vertical sealing

• Horizontal sealing

• Tear notch cutting

• Flat cutting

• Finished sachet discharge

The 5-lane configuration provides a balanced solution for cosmetic gel sachet production. It is more efficient than a single-lane machine, while still remaining compact and cost-effective for medium-capacity personal care production.

Key Configuration Details

1. Piston Pump Dosing for Viscous Gel

The production order specifies piston pump dosing. This is suitable for petroleum jelly and petrolatum gel because the piston structure can provide stable filling volume for semi-solid gel products.

For 5g cosmetic gel sachets, the dosing system needs to avoid dripping, stringing and inconsistent filling. The piston pump helps improve filling stability, especially when the product is not free-flowing.

2. Siemens Control System

The machine uses a Siemens control system, which is important for multi-lane packaging stability. It helps coordinate the main movements, including film pulling, filling, sealing and cutting.

For cosmetic sachet packaging, stable control is not only about speed. It also affects sachet length consistency, sealing timing and long-term production reliability.

3. 304 Stainless Steel Machine Frame

The production order requires a 304 stainless steel frame. For cosmetic and personal care products, stainless steel structure provides better hygiene, corrosion resistance and long-term durability compared with painted steel frames.

This is especially suitable for products such as:

• Petroleum jelly sachet

• Vaseline gel sachet

• Petrolatum gel sachet

• Skin care gel sachet

• Personal care cream sachet

• Cosmetic sample sachet

4. 440mm Film Width for 5-Lane Production

The machine is designed for 440mm total film width. With 5 lanes and 42mm sachet width, the machine can support compact sachet production while maintaining enough space for sealing, lane separation and cutting.

5. Easy Tear and Flat Cut Design

The order includes straight tear notch and flat cut. This is practical for single-use cosmetic sachets because end users need to open the package easily without scissors.

For retail samples, travel packs and promotional cosmetic sachets, easy tear performance directly affects user experience.

Production Capacity Analysis

The required speed is 30–40 cuts per minute. Since this is a 5-lane machine, the estimated output is:

The final speed depends on product viscosity, filling temperature, film material, sachet length and sealing performance. For petroleum jelly products, stable filling and sealing are usually more important than simply chasing maximum speed.

Application Range

Although this project is designed for 5g petroleum jelly / Vaseline gel, the same machine concept can also be used for other cosmetic and personal care gel products, such as:

• Petrolatum gel sachet

• Vaseline gel sample sachet

• Skin care cream sachet

• Hand cream sachet

• Moisturizing gel sachet

• Cosmetic lotion sachet

• Personal care ointment sachet

• Hair care cream sachet

• Body care gel sachet

For different viscosity levels, the dosing pump, hopper, filling nozzle and sealing parameters should be adjusted according to the actual product test.

Why the Customer Chose This Solution

This project required a practical balance between accuracy, sealing reliability, machine cost and production capacity. A 5-lane configuration was suitable because the customer needed higher output than single-lane packaging, but did not require a very large 10-lane or 12-lane system.

Samfull provided a solution based on the actual production order rather than using a generic liquid machine configuration. The main advantages were:

• Suitable for viscous petroleum jelly gel

• Piston pump dosing for 5g filling

• 5-lane structure for higher efficiency

• 304 stainless steel frame for cosmetic production

• Siemens control system for stable operation

• Compact sachet size support: 42mm width, 80–160mm length

• Easy tear notch for consumer convenience

• Composite film support for leak-resistant sachets

Final Solution Summary

For this Netherlands cosmetic customer, Samfull supplied one set of SF720Y-5 5-lane liquid sachet packaging machine for 5g petroleum jelly / Vaseline gel / petrolatum gel sachets.

The solution focuses on stable piston pump dosing, reliable 5mm sealing, clean sachet appearance and efficient 5-lane production. It is suitable for cosmetic sample packs, personal care sachets and small-dose gel packaging applications.
