Zhejiang Rocket Packaging Technology CO.,Ltd. was established in 2018 with an annual output of over 100 million sets and a construction area of 16,000 square meters. We are located in Taizhou City, Zhejiang Province, China. We are a food packaging manufacturer specializing in the production of PET plastic bottles.
We are committed to the construction of professional brand of "fashion, beauty and cleanliness", always adhering to the concept of "innovation, win-win, integrity and service", and strive to provide our customers with high-quality and more cost-effective plastic products service.
Factory Capacity Statement: We have 2 domestically leading fully automatic feeding systems, 26 injection blow molding production lines, and 38 injection molding equipment to ensure an annual production capacity of 100 million sets of packaging containers.
In industrial B2B procurement, the selection of black plastic bottles bulk is rarely just an aesthetic choice. Black PET (Polyethylene Terephthalate) and HDPE (High-Density Polyethylene) play a pivotal role in preventing photo-degradation. Many premium organic compounds, chemical formulas, essential oils, and nutritional supplements are highly sensitive to ultraviolet (UV) radiation.
By utilizing advanced black masterbatches during the injection blow molding stage, manufacturers ensure that the final container acts as a complete physical barrier to light waves ranging from 200 to 400 nm. This preserves the efficacy of active ingredients, prevents oxidation, and significantly extends the shelf life of food, cosmetic, and industrial products.
As environmental regulations tighten across the European Union (EU) and North America, the sourcing landscape for bulk plastic packaging is undergoing a profound transformation. There is a massive rise in demand for PCR (Post-Consumer Recycled) black PET bottles.
Historically, standard black carbon pigment restricted plastic sortability at municipal recycling facilities. Today's industry-leading exporters, particularly in China's manufacturing hubs like Taizhou, are integrating NIR-detectable (Near-Infrared) black colorants. This breakthrough allows sorting systems to classify and recycle black plastics, helping global brands meet strict sustainability quotas.
| Material Type | UV Protection Level | Common Application Cases | Recyclability Rating | Ideal Temp Range |
|---|---|---|---|---|
| PET (Polyethylene Terephthalate) | Excellent (Complete Barrier) | Beverages, Cosmetics, Premium Seasonings | High (NIR-detectable black) | -20°C to 60°C |
| PP (Polypropylene) | High (Moisture & Gas Barrier) | Hot-fill sauces, Candy, Pharmaceutical caps | Medium | 0°C to 110°C (Hot-fill safe) |
| HDPE (High-Density PE) | Maximum (Opaque Barrier) | Industrial chemicals, household detergents | High | -40°C to 80°C |
Taizhou City, located in Zhejiang Province, serves as the heart of China’s advanced polymer manufacturing. Our smart infrastructure provides unparalleled advantages to buyers worldwide.
Operating in Zhejiang puts us at the center of the world's most dense mold-making and plastics tooling network. This reduces custom development times by up to 45% compared to other regions.
Our 2 domestically leading fully automatic feeding systems ensure raw material purity, eliminating manual contamination. Each batch meets international compliance guidelines for food and skincare applications.
Leveraging 26 injection blow molding production lines and 38 injection molding equipment, we can comfortably deliver orders of over 1,000,000 units within highly compressed schedules, reducing lead times to key global ports.
Our packaging solutions are tailored to specific global standards, ensuring safety, functional integrity, and high-end market positioning.
PET is a non-toxic plastic, which meets the safety requirements of food packaging. It will not react chemically with food to produce harmful substances, which can ensure the safety of food.

High transparency: PET plastic bottles have good transparency, which can show the color and texture of cosmetics well. For example, for lipstick, lip gloss and other products, consumers can directly see the color of the product through the transparent bottle, which is convenient to choose their favorite color number; for essence, lotion, etc.,

High gloss finishes suggest modern elegance and clean formulations, widely popular for shampoo, body washes, and wellness products. Matte black coatings, on the other hand, communicate organic properties, luxury, and durability—often targeted toward premium male grooming ranges and high-end essential oils. At Rocket Packaging, we utilize in-line surface treatments to achieve both high-gloss reflections and soft-touch matte aesthetics.
For exporters supplying to the US and EU markets, meeting FDA and EFSA standards is non-negotiable. B2B buyers must prioritize suppliers using virgin food-contact grade resins. When sourcing in bulk, ensure your manufacturer supplies third-party laboratory verification (such as SGS or Intertek certificates) showing non-detectable levels of BPA, plasticizers, and heavy metal residues.
Premium dispensers, colored lotion pumps, custom food-grade structures, and essential oil bottles designed to upgrade your packaging aesthetic.

Black PET bottles offer complete UV light barrier protection. Light-sensitive products like vitamins, serums, cosmetic chemicals, and beer undergo rapid photo-oxidation when exposed to sunlight. A black formulation blocks light waves from passing through the plastic, preserving active ingredients and considerably lengthening product shelf life.
For standard models available in our mold inventory, our MOQ is highly flexible. For custom geometries, surface patterns, or specialized materials (like high-percentage PCR resins), our MOQ usually starts from 10,000 units. This depends heavily on the specific machine requirements (injection molding vs. blow molding lines).
Yes. However, standard black plastics containing carbon black are often difficult for municipal sorting machines to detect. To address this, Zhejiang Rocket Packaging offers high-quality, NIR-detectable black pigments. These allow recycling facilities to recognize the material and process them correctly, assisting brands in achieving circular economy goals.
Our facility runs 2 domestically leading fully automatic feeding systems which prevent material cross-contamination. We also employ 26 injection blow molding production lines and 38 injection molding machines. Each run is subjected to automatic leak testing, wall thickness verification, and strict neck finish dimensional checks to ensure compatibility with all cap styles.
Absolutely. We offer various surface modification techniques, including frosted effects, silk-screen printing, hot stamping (silver/gold foil), and UV electroplating. You can select either a rich matte finish for organic product positioning or a high-gloss, premium finish for retail visibility.
