Major Stages of Sachet Packaging
| Stage | Purpose |
|---|---|
| Material Preparation | Product readiness |
| Film Feeding | Packaging material supply |
| Forming | Sachet creation |
| Filling | Product dosing |
| Sealing | Product protection |
| Quality Inspection | Compliance verification |
Step 1: Product Preparation
The first stage of the sachet packaging process involves preparing the product according to approved manufacturing specifications. Powders, granules, liquids or semi-solid formulations are checked for quality before packaging.
Pre-Packaging Checks
- Appearance Verification
- Weight Confirmation
- Moisture Testing
- Microbial Compliance
- Batch Approval
Step 2: Packaging Material Selection
Appropriate packaging films are selected based on product characteristics and shelf-life requirements. The packaging material must provide excellent barrier protection against moisture, oxygen and light.
Common Sachet Packaging Materials
- PET Film
- Aluminium Foil Laminates
- LDPE Layers
- BOPP Film
- Multilayer Laminates
Step 3: Forming and Filling Process
During this stage, automated packaging machines convert packaging film into sachet shapes. The product is accurately filled according to predefined weight or volume specifications.
A properly controlled sachet packaging process ensures precise filling, reduced wastage and consistent product quality.
Step 4: Sealing Process
After accurate filling, the sachets undergo a sealing process where heat and pressure are applied to create airtight seals. Proper sealing protects the product from moisture, contamination and environmental exposure.
A well-controlled sachet packaging process ensures leak-proof packaging and maintains product integrity throughout its shelf life.
Types of Sealing Methods
- Heat Sealing
- Impulse Sealing
- Ultrasonic Sealing
- Continuous Band Sealing
Step 5: Coding and Printing
Each sachet is printed with important product information such as batch number, manufacturing date, expiry date and regulatory details. Coding ensures traceability and compliance with packaging regulations.
Step 6: Quality Inspection
Quality inspection is a crucial stage of the sachet packaging process. Finished sachets are inspected to verify packaging integrity, weight accuracy and overall product quality.
Quality Checks Performed
- Seal Integrity Testing
- Leak Testing
- Weight Verification
- Print Verification
- Visual Inspection
- Packing Accuracy Check
