Description
4 side sealing packing machine is used to make individual sealed pouches with a strong seal on all four sides. It is commonly used when the product needs protection from moisture, air, dust or outside contamination.
SUNSEE can recommend the feeding method, pouch size range, sealing configuration and optional functions according to your product sample, packaging material and required capacity.

How the Machine Works
- Product feeding
The machine feeds flat products into the packing position. The feeding system can be customized for different product types, such as patches, strips, sheets or test kit components.
- Pouch forming
The packaging material is unwound from roll film and formed into the pouch structure.
- Product filling
The product is placed into the film before sealing.
- Four side sealing
The machine seals the pouch on all four sides to protect the product and keep the package stable.
- Cutting and output
The sealed pouch is cut into individual packs and sent to the next process, such as coding, inspection, labeling or cartoning.
Compatible Packaging Materials
The 4 side sealing packing machine can work with many flexible packaging materials. Common choices include:
| Material Type | Examples | Common Reason for Use |
|---|---|---|
| Plastic film | PE, PP | Cost-effective packaging and basic sealing |
| Laminated film | PET/PE, PET/PP | Better stiffness, clarity and barrier performance |
| Metallized film | MET-PET, MET-PP | Improved light, oxygen and moisture barrier |
| Aluminum foil laminate | Foil composite materials | Strong protection for medical and pharmaceutical products |
| Paper-based material | Kraft paper, coated paper | Printed or eco-positioned packaging |
| Specialty material | Biodegradable film, nylon composite | Special barrier, puncture resistance or sustainability requirements |
Material selection should be based on product sensitivity, seal strength, storage condition, print requirement and industry compliance.
Machine Configuration Options
| Option | Purpose |
|---|---|
| Automatic feeding system | Reduces manual labor and improves packing consistency |
| Date coding or batch coding | Prints production date, batch number or traceability code |
| Easy-tear notch | Helps consumers open the pouch |
| Customized sealing mold | Matches pouch size and product shape |
| Multi-lane design | Increases output for high-volume production |
| Cartoning connection | Connects pouch packing with downstream box packing |
When to Choose This Machine
Choose a 4 side sealing packing machine when your product is flat, thin or sheet-like and needs a sealed individual pouch. It is a good choice for medical, healthcare, personal care and light industrial products where clean sealing, stable packaging and repeatable output are important.
For irregular products or products that cannot be fed automatically, the packing speed may be lower. SUNSEE can check your sample first and suggest whether automatic feeding, manual placement or a customized feeding system is more suitable.

FAQ
What products can a 4 side sealing packing machine pack?
It can pack flat products such as transdermal patches, hydrogel patches, cooling patches, medical plasters, rapid test kits, teeth whitening strips, cosmetic patches, small medical sheets and similar products.
What is the normal output speed?
The standard output range is about 80-150 pcs/min. Actual speed depends on product shape, pouch size, material, feeding method and machine configuration.
Can the machine use aluminum foil material?
Yes. Foil laminate can be used when the product needs stronger protection from light, moisture or oxygen. The sealing temperature and pressure should be tested according to the material structure.
Can SUNSEE customize the feeder?
Yes. The feeding system can be designed according to the product sample. For flat and regular products, automatic feeding is usually possible. For irregular products, SUNSEE can check the sample and recommend a suitable feeding method.
What information is needed before quotation?
Please send the product sample or photo, product size, pouch size, packaging material, required speed, feeding method and optional functions. This helps SUNSEE recommend the right machine model and configuration.
