Hangzhou Zhongheng Packaging Machinery Co., Ltd.
Hangzhou Zhongheng Packaging Machinery Co., Ltd. makes automatic weighing and quantitative packaging systems in Hangzhou, Zhejiang. Its catalogue covers multihead and linear weighers, vertical baggers, premade-pouch machines, can-filling and integrated systems, and inspection and auxiliary equipment. The best-documented model is the ZH-GD8-200, an eight-station rotary pouch machine that takes bag widths of 100–200 mm and lengths of 100–350 mm, rated at up to 50 bags/min. Zhongheng is a good fit for buyers who want the weigher and the packer supplied together for granular, flaked, strip-shaped, spherical or powder products.

SECTION 01
What Zhongheng makes
The company page describes a manufacturing operation in Hangzhou built around automatic weighing and quantitative packaging. [1] Each product family does a different job in a line, so the first step is knowing which ones your project needs.
Swipe or scroll the table to compare all columns.
| Product family | Job in the line | What to tell Zhongheng |
|---|---|---|
| Multihead and linear weighers | Portion the product before discharge | Material behaviour, target portion and the packer it feeds |
| Vertical packaging machines | Form bags from roll film and pack the dose | Film structure, bag style and forming arrangement |
| Premade-pouch equipment | Open, fill and seal bags bought ready-made | Bag opening, zipper type and seal material |
| Can-filling and integrated systems | Link dosing with containers or a full line | Exact container, closure and downstream equipment wanted |
| Inspection and auxiliary equipment | Support the main packing machine | Which devices are included and what each one checks |
For tins and jars, compare the can-filling range against other filling equipment on the site. For bags, pick the packaging route first and the dosing set-up second. [1] [2]
SECTION 02
Featured model: ZH-GD8-200
The ZH-GD8-200 rotary pouch packer is Zhongheng's most fully specified machine and a sensible starting point for a quote. It handles flat bags, stand-up bags and zipper stand-up bags in composite, PE and PP films. Zhongheng lists motor-driven bag-width adjustment and a bag-opening check that stops filling and heat sealing when a bag fails to open. [2]
Within the listed sizes, ask Zhongheng to approve your own laminate and filled-bag weight with samples. The full specification table and a suggested trial plan sit on the machine page.
SECTION 03
Vertical bagger or premade pouch
Zhongheng sells both routes, and each one buys a different packaging material. A vertical machine forms every bag from roll film, so you specify a film. A premade-pouch line takes finished bags with the zipper and gusset already made, so you buy pouches. Decide on the finished bag first, then compare machine prices. [1]
Wolf's VCI series shows the roll-film approach. It forms bags from film and starts filling after each bag-bottom seal.
SECTION 04
Matching the weigher to your product
The ZH-GD8-200 page names granular, flaked, strip-shaped, spherical and powder materials. [2] These behave very differently on a weigher. A fragile chip and a dense plastic pellet can both count as granular in a catalogue, yet one breaks easily and the other makes a heavy bag.
Send Zhongheng your real product and ask for a test that records breakage, bridging, product in the seal area and dose stability. Dusty, cohesive or sensitive powders each need a dosing arrangement chosen for that powder.
SECTION 05
Getting a complete line quotation
Zhongheng can quote the weigher, bagger and handling as one system. Ask for a single offer that follows the whole product path: feed into the weigher, dosing, transfer into the bag, bag handling, sealing, discharge and any checks after packing. Preparing a packaging brief explains how to set out each step for a supplier.
Request an equipment list and a layout that name who supplies each connection. A quote for the bag machine alone will look cheaper than one that includes lifting, weighing, platforms and inspection, so compare offers with the same scope.
Ask how cleaning access, product changeovers and bag-format changes work. The motor-driven width adjustment covers one task. A change of material, dose, film or upstream feeding can add others. [2]
SECTION 06
Service and training
The company website includes service videos for weighers, vertical machines, elevators and pouch machines. [1] They help with operator training. Agree local engineer support, spare-parts stock and response time for your country as separate items in the contract.
SECTION 07
Confirm before ordering
Ask Zhongheng to confirm these points in writing for your order:
The product page carries a CE label. Request the declaration and technical documentation for the exact machine you order and for your destination market.
Company size, customer numbers and rankings appear in Zhongheng's own promotion. Ask for references in your industry if they matter to your decision.
For pharmaceutical, aseptic or hazardous-material work, ask whether Zhongheng has supplied a line for that use and request the documents.
Price, current lead time, installation supervision, utility use under load and accepted output for your recipe all belong in the proposal.

SECTION 09
Buyer questions
Does 50 bags/min describe a complete Zhongheng line?
No. It is the rating of the ZH-GD8-200 pouch machine. The product feed, weigher and downstream equipment need to run at one shared speed. [2]
Does Zhongheng make both the weigher and the bagging machine?
Yes. The catalogue lists multihead and linear weighers alongside vertical and premade-pouch machines, so one supplier can quote both. [1]
Can Zhongheng handle powders?
Powder appears in the material list for the ZH-GD8-200. Send a sample of your powder so Zhongheng can propose a dosing unit that suits its flow and dust level. [2]
