BUYER GUIDE / INDUSTRIAL
10 China Custom Thermoformed Packaging Manufacturers to Evaluate
This is a non-ranked buyer research list, not an award, audit or recommendation. It compares ten China-based thermoformed packaging suppliers using public company pages or clearly identified marketplace profiles. Wenzhou Tonghou Plastic Products Co., Ltd. publishes the guide and appears in it; every supplier, including Tonghou, still requires project-specific verification.

- Publicly stated focus
- Public company pages describe heavy-gauge vacuum forming, industrial housings and custom thermoformed parts.

Dongguan, Guangdong
Dongguan Jiasheng Plastic Packaging Products Co., Ltd.
- Publicly stated focus
- Its company page states a focus on food and medical blister packaging and related packaging formats.
- Buyer follow-up

- Publicly stated focus
- Its public site describes heavy-gauge thermoforming, industrial parts and in-house plastic-sheet directions.

- Publicly stated focus
- Its custom-tray page covers packaging inserts, handling trays and applications including electronics, medical, food and industrial products.
- Buyer follow-up
- Use drawings or samples to verify material, geometry, tooling and sample checks; do not treat published timing or capacity statements as independently verified.
Shenzhen, Guangdong
Shenzhen Ameixin Plastic Co., Ltd.
- Publicly stated focus
- A public marketplace profile describes thick-sheet vacuum-formed parts, machine covers and display products.
- Buyer follow-up
- Confirm the current company identity and operating site directly. The domain ameixin.com.cn is excluded because it now identifies an unrelated audiovisual-technology company.

- Publicly stated focus
- Its public company page describes plastic blister trays, clamshell packaging and related plastic packaging formats.

- Publicly stated focus
- A public marketplace profile lists blister trays, clamshells, folding plastic boxes and related packaging.
- Buyer follow-up
- Confirm current operating status, factory location and which processes remain in-house because the former standalone website is not used as evidence here.

- Publicly stated focus
- Tonghou publishes owner-confirmed production categories including PP food and mooncake trays, PETG pharmaceutical and medical protective trays, PS antistatic electronics trays, flocked inserts, fabric-covered PVC inserts, industrial trays and transparent packaging.

Xiamen XieFa Vacuum Forming Packaging Co., Ltd.
- Publicly stated focus
- Its company page describes food-packaging products and multiple plastic or alternative-material directions.
- Buyer follow-up
- Request current certificates and reports for the legal entity, then confirm the exact food type, temperature, storage and market requirements for the project.
01
Applications
- Buyers building an initial China supplier shortlist
- Projects that need thin-gauge trays, blister packaging or presentation inserts
- Industrial projects comparing thin-gauge and heavy-gauge thermoforming sources
02
Selection criteria
- A public source that identifies the company and stated product direction
- A product focus that matches the intended packaging or industrial application
- Clear separation between company statements and independently verified evidence
- A practical follow-up question for drawings, samples, material and validation
03
Pre-production validation
Treat every entry as a research starting point. Before qualification, confirm the current legal entity, factory location, contact channel, relevant production process, sample plan and project-specific evidence. Request current documents directly rather than relying on an article, marketplace badge or undated website claim.
04 / DECISION MATRIX
Buyer decision table
| Project direction | Publicly stated suppliers to investigate | What the buyer still needs to verify |
|---|---|---|
| Food and disposable thin-gauge packaging | Xiamen XieFa; Dongguan Jiasheng | Material grade, intended contact conditions, current documents and representative samples |
| Custom trays, inserts and blister formats | Tonghou; Haixu; Stardeal; Keymy | Product fit, material direction, tooling path, sample checks and change control |
| Heavy-gauge industrial thermoforming | Ameixin; Yiyongli; Ditai | Current forming envelope, thickness range, trimming, tooling and project references |
| Blister packaging plus folding-box range | Wing Kam | Current operating status, production location and whether the required processes remain in-house |
05 / BUYER QUESTIONS
Common buyer questions
01Is this a performance ranking of thermoforming manufacturers in China?
No. It is a non-ranked research list based on public sources. No score, award, performance audit or recommendation status is assigned.
02Why is Tonghou included in a list published by Tonghou?
The publisher relationship is disclosed so buyers can judge the source. Tonghou receives no preferential score or placement and should be verified using the same project questions as every other supplier.
03Does a company website prove its certifications or capacity?
No. A website is a company statement. Request current documents that identify the legal entity, scope, issuer and validity period, and verify project-specific capability separately.
04How should I compare thin-gauge and heavy-gauge suppliers?
Start with the actual part. Packaging trays and industrial housings differ in sheet thickness, forming envelope, trimming, tooling, validation and downstream processes.
05What should I send to shortlisted suppliers?
Send the same drawing or sample, use conditions, quantity, outer-pack constraints and validation questions to each supplier so responses can be compared on equal assumptions.
