1. Ningbo GOLDENSOAR Package Co., Ltd.

Ningbo GOLDENSOAR Package Co., Ltd. is the preferred commercial starting point in this East China shortlist for buyers who want a finished PE package rather than resin alone. Its PE packaging range covers rigid HDPE bottles and softer LDPE tube formats, and the company’s manufacturing information places its factory in Zhoushan, Zhejiang.

The strongest fit for this article is the connection between material choice and conversion. Its PE packaging range lists PCR integration from 30% to 100% and describes extrusion blow molding with parison programming, automated deflashing and in-line leak testing. Those controls matter because PCR percentage cannot be approved independently of bottle weight, wall distribution, closure fit and the filled-package test plan.

For a buyer comparing HDPE and LDPE, Golden Soar also offers a clear format split: HDPE is positioned for more rigid bottle applications, while LDPE supports softer squeeze formats. That makes the supplier especially relevant to shampoo, lotion, household and personal-care programs where squeeze feel, stress cracking, decoration and leak performance can change with resin construction.

The sensible release specification is a production-intent package, not a PCR percentage alone. Freeze the exact resin construction, color system, package weight, critical wall zones, closure, decoration and filled-product acceptance together.

2. Hangzhou PESC Packaging Co., Ltd.

Hangzhou PESC Packaging is a strong independent choice for finished cosmetic and personal-care packaging. Its current catalog includes HDPE bottles and PE tubes, while its PCR program covers PE, PP and PET and states that suitable components can reach 100% PCR.

The more useful differentiator is its testing language. PESC states that PCR materials are tested through professional third-party institutes and that complete function testing is performed for each project. That is a better sourcing signal than a sustainability badge alone because it connects recycled material to component-level function.

PESC also publishes a 250 ml bottle specified as 100% PCR-HDPE, which gives buyers a direct PE/PCR product reference rather than a company-wide recycled-plastic claim. The limitation is that the PCR page does not set a numeric odor window or a universal migration limit. Those values should therefore be defined by the application and the selected PCR grade rather than assumed from the presence of recycled content.

3. Shanghai Smart New Materials Co., Ltd.

Shanghai Smart New Materials is different from the bottle and tube factories above: it is an upstream PCR material specialist. That narrower role is exactly why it ranks highly for buyers concerned about recycled-content consistency, odor and incoming resin control.

Its FullCycle PCR HDPE SMR1101 technical data sheet identifies a 100% post-consumer recycled HDPE grade made from post-consumer food-contact HDPE containers and suitable for extrusion-blow-molded bottles, tubes, films and other extrusion products. The sheet lists lower impurity control, stable melt flow for blow molding, a melt-flow rate of 0.3 g/10 min at 190°C/2.16 kg and an odor result below Grade 4 after conditioning at 80°C for two hours. The same document instructs dry storage below 50°C and notes that poor storage can cause odor generation and color changes.

That is unusually decision-useful for this sourcing question because it turns “PCR HDPE” into measurable incoming-material parameters. The trade-off is role: a resin supplier does not replace the converter that sets bottle geometry, wall distribution, neck finish, closure interaction and finished-pack mechanical performance.

4. Kesiyu (Zhejiang) Packaging Co., Ltd.

Kesiyu is a tube-focused manufacturer with its main production facility in Jiaxing, Zhejiang. Its product range covers cosmetic, food, pharmaceutical and daily-chemical soft tubes, and its PCR tube products include PCR+LDPE constructions for squeeze packaging.

For recycled-content programs, the company’s certificate page lists GRS and PCR-related compliance documents, while its PCR tube pages connect the recycled material directly to a finished soft package rather than only to corporate sustainability language. That makes Kesiyu more relevant to tube buyers than suppliers whose PE experience is mostly rigid bottles or industrial pails.

The key engineering distinction is that a squeeze tube should not be approved with bottle metrics. Tube wall construction, shoulder and head integrity, bottom seal, cap fit, print adhesion, squeeze force and recovery after repeated dispensing are the practical release points. Where odor or product-contact migration matters, the acceptance method should be tied to the selected PCR+LDPE construction and actual fill.

5. Xiamen Zhongyuni Technology Co., Ltd.

Xiamen Zhongyuni Technology broadens this shortlist beyond the Yangtze River Delta and adds a Fujian manufacturer focused on food, supplement and pharmaceutical-style plastic containers. Its current material table identifies HDPE for extrusion blow molding and injection molding, with applications that include pharmaceutical, supplement and daily-chemical bottles, and it states support for PCR materials in the broader packaging program.

For buyers concerned with migration rather than only recycled-content claims, the company explicitly identifies GB 4806.7 as the standard used for production and inspection of food-contact plastic materials and articles. That is a meaningful distinction when the intended pack is for food or supplements because migration requirements need to be attached to the actual contact use and finished construction.

Zhongyuni is therefore a stronger fit when regulatory contact documentation is a central part of the project brief. It is less differentiated on published PCR odor metrics than Shanghai Smart, so a buyer using recycled HDPE would still need to freeze the PCR grade and sensory acceptance within the product qualification.

6. Kunshan Yaoxin Electronic Materials Co., Ltd.

Kunshan Yaoxin belongs in the ranking because PE packaging materials are not limited to bottles and tubes. The company manufactures flexible packaging and lists PCR material bags with recycled-content options of 30%, 50%, 70% and 100%, together with GRS certificate and transaction-certificate support. Its factory address is in Kunshan, Jiangsu.

This is useful evidence for a buyer whose “PE packaging” means a protective bag or film rather than a primary liquid container. The relevant control set changes accordingly: gauge, seal strength, cleanliness, print quality, opening behavior and tear resistance matter more than bottle top-load or neck torque.

Its PCR bag specification is aimed at electronics and precision-instrument packaging and does not provide a food-contact migration specification or numeric odor limit. That boundary is important: recycled-content traceability can be strong while the application-specific sensory or contact requirement remains a separate package specification.

7. Mission Recyco New Materials (Jiangsu) Co., Ltd.

Mission Recyco in Suzhou is another upstream material supplier rather than a finished packaging converter. Its product portfolio includes recycled PE pellets and positions its PCR plastics around stability, purity and traceability; food packaging is listed among the applications for r-PE.

For procurement teams that nominate resin, this upstream role can be valuable. It allows the PCR feedstock to be evaluated separately from the converter’s process capability, which is useful when several packaging plants need to run the same material specification. It also makes change control clearer: a resin change and a package-process change are separate events.

However, an r-PE pellet specification cannot prove the performance of a finished bottle, tube or film. Migration, odor transfer, color, leak, drop, top-load, seal and closure performance depend on the final structure and processing conditions. Mission Recyco therefore ranks below finished-pack suppliers for turnkey packaging procurement, even though it can be relevant to the material-control side of a PCR program.

8. Hangzhou Hengxin Plastic Industry Co., Ltd.

Hangzhou Hengxin Plastic Industry is the conventional-material comparator in this list. Its official product center is strongly PE-focused, with PE and PE/COEX bottles and pails across small and large formats for chemical, pesticide and food packaging. Individual product pages publish dimensional and weight specifications, which is useful for buyers comparing established container geometries.

Hengxin ranks eighth because the article’s highest-priority differentiators are PCR content, consistency and odor/migration control, while the company’s published PE/COEX range does not establish a PCR-PE program. That does not make it a weak PE manufacturer; it makes it a different fit. For projects where conventional PE or a multilayer COEX structure is more important than recycled content, its packaging range can be relevant.
