Main Applications
1. Producing resealable zip bags for folded clothing and knitwear packaging
2. Manufacturing garment bags for apparel exporters and textile wholesalers
3. Making zip-top bags for food packaging where resealing matters
4. Producing stationery and small retail item packaging with a zip closure
Core Functions
The zipper welding system is the defining feature of this machine — a forged copper heating knife attaches the top button zip strip to the film, while a separate forged steel knife and cold knife handle bag cutting, keeping the heat-sensitive welding step apart from the cutting step.
Unwinding runs on a 600mm-diameter system with automatic deviation correction, magnetic-particle constant tension control, automatic feeding, and automatic shutdown when the film roll runs out — reducing the amount of manual monitoring needed during a production run.
Two pneumatic punch stations are built in: one for round holes and one with an interchangeable head for portable-style holes, letting the same machine handle different hole styles without a separate punching unit.
A Mitsubishi PLC paired with a Taiwan-made touch screen controls the whole line, while photoelectric tracking (imported from Germany) keeps film alignment accurate as it moves through zipper welding and cutting.
The drive system uses a stepping motor as standard, with the option to upgrade to a servo motor for buyers who need tighter precision at higher output.
Practical Solutions
Converters new to zip-bag production often run two separate machines — one for zipper attachment, one for bag forming — which adds handling steps and machine costs. This machine combines both into a single line, cutting out that extra step entirely.
Zip strip welding quality is a common failure point on lower-grade equipment, where uneven heat can weaken the zipper seal. The forged copper welding knife on the WY-800 Automatic Top Button Zipper Bag Making Machine is built specifically to keep that weld consistent across a full production run.
Buyers looking for zip bag machinery can benefit from a reliable export supplier that provides efficient zipper-welding solutions, stable production performance, and flexible shipping options. This machine delivers the zipper-welding functions required for modern bag manufacturing while helping international customers optimize procurement processes and improve production efficiency.
OEM/ODM Support
Wenzhou Chaoshun Machinery offers OEM and ODM adjustments on this machine, including drive system upgrades (stepping motor to servo motor), punch head configuration, and accessory brand selection. Buyers producing a specific garment bag size range or targeting a particular film type can work with the factory to configure the WY-800 Automatic Top Button Zipper Bag Making Machine before delivery.
