Company profile
Paper packaging machinery built on standard platforms.
SINOTOP manufactures machines and complete production lines for paper protective packaging. The proven standard platform is the starting point, and the configuration is matched to the finished product, the plant and the grid it will run on. More than 95% of the machines are delivered overseas.

Company profile
A machinery manufacturer built around standard platforms.
The company sells standard machines and standard production lines, and adjusts the configuration to the customer instead of designing every project from zero.
What we manufacture
Paper angle board lines, paper honeycomb lines, solid cardboard lines and anti-slip paper lines, together with base paper slitting, die-cutting and cutting machines supplied as separate units.
The materials these lines produce are protective packaging: corner and edge protection, honeycomb cushioning and structural board, solid board and anti-slip paper wherever products need protection, transit packaging or structural packaging.
How an order is built
Machines are made to order rather than held in stock, because voltage, configuration and function requirements differ from country to country and from project to project.
Common adjustments are the national voltage, capacity, finished-product specification, line speed, function modules and electrical configuration. Requests outside the standard range are reviewed by the technical team before anything is promised.
Who we work with
Most customers are factories that produce paper packaging materials themselves: carton plants, paper tube plants, and producers adding a new paper packaging product or extra capacity.
A small number of customers are equipment agents working in the machinery trade.
Team and engineering
Engineering review before anything is quoted.
The company works with a technical team of about ten to twenty specialists, and configuration questions are checked technically before they reach a quotation.
Team
A technical team of about ten to twenty specialists, organised around export orders. More than 95% of the machines are delivered outside China.
Because machines are used for a decade or more, most repeat business comes from existing customers: another line of the same type when capacity runs short, or a different product family once the first line is running.
Configuration engineering
Voltage and electrical configuration, capacity, finished-product specification, line speed and function modules are fixed with the customer during the configuration review.
A requirement outside the standard range — a new mechanical structure, a new process, special raw paper or finished product, higher capacity, a linked line or a special certification — is evaluated by the technical team before it is quoted. Drawings or a target sample from the customer are part of that evaluation.
Control and electrical support
Machine issues most often concern the electrical system, the control programme or the PLC. Most of them are resolved remotely, through diagnosis and a programme update, without a service visit.
Production scope
Four standard production lines.
Each line is built on a proven standard platform, and the configuration is matched to the raw paper, the finished product and the output of the plant it is going to.
Paper honeycomb line
Produces paper honeycomb core and honeycomb board for cushioning and structural packaging.
HONEYCOMB CORE
HONEYCOMB BOARD
Solid cardboard line
Produces solid cardboard where a rigid protective material is required.
SOLID CARDBOARD
Anti-slip paper line
Produces anti-slip paper for palletised loads.
ANTI-SLIP PAPER
Base paper slitting, die-cutting and cutting machines are supplied as separate units alongside these lines.
Quality and delivery
How an order runs, from configuration to commissioning.
Every project follows the same checkpoints, and progress is reported with photos or video at each one.
01
Configuration review
Voltage, capacity, finished-product specification and function modules are confirmed, and anything outside the standard range is reviewed by the technical team.
02
Built to order
A large line takes roughly three to six months; a small machine is usually finished within a month. Machines are not kept in stock, because each order is configured for its market.
03
Milestone reporting
Photos and video are sent at the agreed milestones through assembly, debugging and the trial run, so the project can be followed from a distance.
04
Pre-shipment acceptance
The machine is run against the criteria agreed in the contract, verified either by inspection on site or through a live video acceptance.
05
Installation and warranty
Engineers are dispatched for installation and commissioning, usually within two weeks for a large project and three to five days for a small machine. The standard warranty framework is twelve months, with remote diagnosis and programme updates for support.
Export experience
An export-first business from the start.
More than 95% of the machines are delivered overseas. The early orders came from European and American customers and large groups, and India and South-East Asia are among the largest markets today.
European and American start
The business started with European and American customers and large groups. Working to those requirements raised the standard for machine finish, technical configuration and quality across the whole range.
Where the machines go
India and South-East Asia are among the largest markets today, alongside long-standing European and American customers.
India, South America and honeycomb machinery demand are the directions the company is watching next.
How a project is checked
A machine is not sent out as a sample. The technical discussion is supported with machine photos and running video, technical parameters, samples of the paper packaging product, customer evaluation emails and, where available, references from known converters.

Documents
Certificates and compliance documents.
Compliance documents are confirmed with the order. Electrical and safety requirements differ by destination market, so the documents that apply to a project are agreed for that project rather than advertised in general terms.
Company documents
The company documents that go out with an inquiry. The exact set is confirmed with the order.
Market compliance documents
