How we work
From requirement review to delivery in China
Materials and finishes differ in colour, feel, cost and production constraints. We define the project boundaries first, then use physical samples to turn the desired result into a repeatable production standard.
- 01Requirement review
Confirm the product, dimensions, quantity, budget, target date and delivery location.
- 02Material and structure proposal
Recommend options based on presentation, use, transport and cost requirements.
- 03Artwork check and sampling
Review production files and prepare the relevant structural, printed or finish sample.
- 04Production and quality checks
Produce against the approved sample and inspect key processes, finished goods and packing requirements.
Quality focus
Define acceptable standards within the project
- Verify dimensions, thickness and seal strength
- Check zipper or closure stability
- Test ink adhesion and print registration
- Validate with actual packing and transport conditions
Buyer FAQs
Plastic & E-commerce Bags FAQ
How should PE, PP and PET be selected?
They differ in transparency, softness, stiffness, heat response and converting method. Selection should follow the product and use environment.
Can bags carry custom brand printing?
Yes, subject to material, quantity and print requirements. Please provide print area, colours, front/back layout and references.
How do zipper bags and self-adhesive bags differ?
Zipper bags are generally reclosable; self-adhesive bags seal with a glue strip. Cost and user experience differ.
Are these products made by JC Packaging in Haining?
Plastic and laminated bags are mainly made by specialist partner suppliers. Sincere Packaging manages supplier matching, sample coordination, project control and delivery.
Can materials be described as biodegradable or eco-friendly?
Only when the actual material, tests, standard and supplier documentation support the claim. Environmental claims cannot rely on a material name alone.
