Quick answers
Facts buyers most often verify
What is the relationship between Sincere Packaging and JC Packaging?
Haining Jiecheng Printing Industry Co., Ltd. is the parent company of Shanghai Sincere Packaging Co., Ltd. and the core manufacturing supplier.
Are all eight locations Sincere-owned offices or factories?
No. Shanghai is the Sincere office and Haining, Zhejiang is the JC Packaging factory. Wenzhou, Changshu, Huzhou, Jiaxing, Dongguan and Jinhua are specialist partner-supply locations.
Can you really start from one piece?
One-piece personalised sampling and suitable short runs are supported. Bulk MOQ is confirmed according to material, print method, tooling and finishing.
How long do samples and bulk production take?
Typical projects take 3–7 days for sampling and 7–15 days for bulk production. Complex structures, special materials, outsourced finishes and approval delays affect actual timing.
Can the food packaging directly contact food?
Our current scope is outer packaging that does not directly contact food. Food-contact inner packaging must come from an appropriately qualified manufacturer with relevant compliance documents.
Where do you mainly deliver?
Primary domestic delivery regions are the Yangtze River Delta and Pearl River Delta. Other Mainland China locations can be evaluated by project.
Are all products FSC certified?
No. An FSC claim requires the actual manufacturer, certificate scope, product group list, material source and order requirements to align.
