Description
A zipper pouch 4 side sealing packing machine combines four-side pouch sealing with a zipper closing system. Compared with a standard 4 side sealing pouch, the zipper pouch can be opened and closed again after first use.
This makes it useful for products that may not be consumed in one time, products that need better storage after opening, or brands that want a more convenient retail package.
SUNSEE can customize the feeding method, zipper sealing system, pouch shape, pouch size and downstream connection according to your product sample and production capacity requirement.

How the Machine Works
- Product feeding
The product is fed into the packing section by a customized feeding system. For soft gel patches, SUNSEE can use a feeder designed to handle delicate products. For harder patches or sheets, a pick-and-place style feeder may be more suitable.
- Film unwinding and pouch forming
The machine uses roll film to form the pouch structure according to the required pouch width and length.
- Zipper application
The zipper strip is added to the pouch area so the final package can be opened and closed again by the consumer.
- Product placement
The product is placed into the pouch position before sealing.
- Four-side sealing and zipper sealing
The machine seals the pouch on four sides and uses ultrasonic sealing for the zipper section. This helps create a stable resealable package.
- Cutting and output
The finished zipper pouches are cut and discharged. The machine can also be connected with downstream equipment such as box packing.
