Ruizhuo PET Packaging
Clear thermoformed containers — hinged clamshells, round and square tubs with separate lids, and flat trays — mostly in PET, made by a Dongguan limited company registered in 2011 whose scope covers plastic-products manufacturing and import/export. The catalogue gives sizes, gram weights and carton packs for 52 item families; food-contact documents are not yet on file. All of it is below.
Clear boxes, by the carton.
Hinged PET Clamshells
The largest group in the catalogue: one-piece clear boxes with a hinged lid, from about 16 × 11 cm up to 46 × 10.5 cm, most weighing 14–37 g and packed 200–800 to a carton. Several carry vent holes. The catalogue does not name an application; by shape they are the boxes used for salads, cut fruit, sandwiches and baked goods — confirm with the factory which one was designed for what.
Round Tubs & Domes with Separate Lids
Round PET bases with separate lids from Ø17.8 cm to Ø32 cm, some 13 cm deep. The heaviest base in the book is 99.2 g (Ø32 × 7.5 cm, RZ-HB005). Lids and bases are packed separately for some items and as sets for others; check which before you count cartons.
Square Containers & Shared Lids
Square bases of 13 × 13, 16 × 16, 22 × 22 and 26 × 26 cm in several depths, with one lid fitting a whole family (for example one 16 × 16 cm lid across RZ-HB014, 015 and 016). A shared lid is useful for a buyer running several portion sizes.
Black-Base Containers
Three items pair a black base with a clear PET lid: two with black PP bases (RZ-HB018, RZ-HB036) and one with a black PET base (RZ-HB049). PP and PET behave differently with heat and are recycled in different streams; ask which base suits your filling and reheating.
Flat Trays & Inserts
Shallow trays such as 32.5 × 27 × 4 cm (34 g) and 31.2 × 22.7 × 3 cm (29 g), and one BOPS tray (RZ-HB007, 34 × 12.5 × 5.7 cm, 12 g). BOPS is an oriented polystyrene — a different resin from PET with its own food-contact rules.
What the Catalogue Does and Does Not Say
Every page gives item number, material, dimensions, gram weight, quantity per carton and carton size. None gives a price, MOQ, lead time, temperature range, food use, recycled content or certificate. A few entries disagree with themselves: RZ-SL044 is listed 40 cm tall where its twin RZ-SL045 is 3.9 cm; RZ-SL047 has no weight; and several pages print one prefix in the heading and another in the specification (SL038 / HB038, HB048–HB050 / SL048–SL050). Ask for a corrected sheet before quoting from it.
What the registry confirms, and what stays open.
Plastics Manufacturing Is in Scope, in Its Own Words
The registry read (2026-09-29, official source) gives the scope as 塑料制品制造；塑胶表面处理；塑料制品销售；新材料技术研发；箱包制造；箱包销售；皮革制品销售；皮革制品制造；包装材料及制品销售；货物进出口；技术进出口 — plastics manufacturing, plastic surface treatment, sale of packaging materials, bag and leather goods, and import/export. A manufacturing clause is present and is quoted as written.
Import and Export Is in Scope
Goods import/export and technology import/export are both in the registered scope, so the company can in principle export under its own name. Confirm that the customs registration is active and that the name on the commercial invoice is the name on your contract.
Above the Industrial-Statistics Threshold Since 2018
A public notice of the Dongguan Bureau of Industry and Information Technology dated 19 June 2020 lists 东莞市瑞卓塑胶制品有限公司 (Daojiao, credit code 91441900579652330H) among firms that were “newly above threshold” in 2018 and grew industrial value added by more than 10% in 2019, with a proposed grant of RMB 100,000. In China the above-threshold line for industrial firms is annual main-business revenue of RMB 20 million. The notice is a government document read in the original.
27 Insured Staff, Capital Part Paid In
The registry read records 27 people on social insurance. Registered capital is RMB 1 million, of which RMB 300,000 is recorded as paid in. There is also a branch office in Wanjiang, Dongguan, registered under the same name.
Court Records: Two Current, One Historical Penalty
Two current own-risk items: one judgment document in a contract dispute in which the company was sued, and one case filing in which it is the party being sued. In the historical items there is one administrative penalty for breaching tax-administration rules. One company it invested in has a deregistration filing. None of this is a conclusion about the company; it is what the register returned on 2026-09-29.
Changes on the Record
The advisory notices record three changes of registered address, one change of registered capital, one investor change and one change of key personnel, plus a name change and an address change at the Wanjiang branch. The current registered address is a street number in Daojiao Town rather than a unit in a named industrial park; ask to see the forming line on video.
What was checked — and what the check found.
The registry read is done: status, scope, capital, paid-in capital, insured headcount, address and the full risk scan come from an official registry source read on 2026-09-29 and are quoted as recorded, including the items that do not flatter the company. The 2020 government notice was read in the original PDF. Everything about the products — item numbers, materials, sizes, weights and carton packs — comes from the company’s own 54-page catalogue, which names no application and carries no price, MOQ, lead time or certificate. No website, test report or food-contact declaration was supplied. This page is updated when documents arrive.
A Dongguan thermoformer since 2011, with the whole record shown.
Ruizhuo is 东莞市瑞卓塑胶制品有限公司 (registered English name Dongguan Ruizhuo Plastic Products Co., Ltd.), registered on 14 July 2011 in Dongguan with registered capital of RMB 1 million, of which RMB 300,000 is recorded as paid in. An official registry read on 2026-09-29 confirms active status, 27 insured staff, a scope covering plastic-products manufacturing, plastic surface treatment and packaging-materials sales, and goods and technology import/export. The registered address is in Daojiao Town, and there is a branch office in Wanjiang.
A Dongguan Bureau of Industry and Information Technology notice of 19 June 2020 lists the company among firms that were newly above the industrial-statistics threshold in 2018 and grew industrial value added by more than 10% in 2019. Its 54-page catalogue shows 52 families of clear thermoformed containers — hinged clamshells, round and square lidded containers and trays — almost all in PET, with item numbers, sizes, gram weights and carton packs. It names no application and gives no price, MOQ, lead time, temperature range or certificate.
The register also carries two current court items (a contract dispute and a case filing, both with the company as defendant), a historical penalty for breaching tax-administration rules, three changes of registered address and a change of registered capital. None of that is a verdict; it is the reason to confirm the contracting entity and payment terms before a first order, and to ask for the food-contact declaration your market requires.
Registered 2011, above threshold by 2018.

Frequently Asked Questions
What does Ruizhuo make?
By its catalogue: clear thermoformed containers — hinged clamshells, round and square bases with lids, and flat trays — in 52 item families, almost all in PET. Its registered scope covers plastic-products manufacturing and import/export. The catalogue gives dimensions, gram weights and carton packs, but no application, price or lead time.
Is this listing CMH-verified?
Yes, on the registry check: an official read on 2026-09-29 confirms active status since 2011, plastics manufacturing and import/export in scope, and 27 insured staff. It does not confirm the forming line, the resin or any food-contact compliance — none of those documents has been supplied.
There is a lawsuit and a tax penalty on the record — should that stop me?
Not by itself, and the page prints them rather than hiding them so you can decide. The two current items are one contract dispute in which the company was sued; the tax penalty is historical. What it means in practice: put payment, quality and delivery terms in writing, and pay against inspection on a first order.
What name should go on the contract?
The registered name 东莞市瑞卓塑胶制品有限公司 with credit code 91441900579652330H. The registry also records the English name Dongguan Ruizhuo Plastic Products Co., Ltd. Other companies with “Ruizhuo” in their English name exist elsewhere in China — match the credit code, not the name.
What food-contact paperwork should I ask for?
It depends on the market. In the United States, PET intended for food contact is covered by FDA regulation 21 CFR 177.1630 (polypropylene by 177.1520, polystyrene by 177.1640), and buyers normally ask the packaging maker for a letter of guaranty or compliance statement tied to the resin. In the European Union and Great Britain, plastic food-contact materials fall under Regulation (EU) No 10/2011 and the good-manufacturing-practice rule (EC) No 2023/2006, and a written declaration of compliance backed by migration testing must travel with the goods. None of these documents is on file for this factory yet. Which tests apply to your food and temperature was not confirmed when this page was written (September 2026) — ask a laboratory.
Does recycled content matter?
Increasingly. The United Kingdom taxes plastic packaging that contains less than 30% recycled plastic, charged to the UK manufacturer or importer; the EU Packaging and Packaging Waste Regulation (EU) 2025/40 phases in recycled-content and recyclability requirements. Recycled PET in food contact needs its own authorised process. Ask whether rPET grades are available and what documentation comes with them; the rates and dates for your market were not confirmed here.
Are single-use plastic rules a problem for clear PET boxes?
Some are. The EU Single-Use Plastics Directive (EU) 2019/904 covers certain food containers for immediate consumption, with consumption-reduction and producer-responsibility obligations set by each member state, and several countries and US states run their own packaging producer-responsibility schemes. Whether a given container is caught depends on how it is used and sold — check with your importer of record.
Which HS code usually applies?
Plastic boxes and containers for conveyance or packing of goods usually fall under HS 3923.10; plastic tableware and kitchenware under 3924.10. Which one applies to a food container depends on how it is presented and used. National tariff lines differ and classification is decided by customs at import; confirm before shipping.
Talk to Ruizhuo PET Packaging directly.
Send the item number from the catalogue (RZ-HB, RZ-SL, RZ-JG, RZ-JD or RZ-SN), the food it will hold and whether it is chilled, frozen or hot-filled, your order quantity in cartons, and whether you need recycled PET content, anti-fog film or a tamper-evident closure. Ask in the same message for a food-contact declaration of compliance for your market (FDA 21 CFR 177.1630 for PET in the United States; Regulation (EU) No 10/2011 in the EU and GB), for the resin supplier’s certificate, and for the unit price per carton. ChinaMakersHub will route the request.
