Direct-from-factory thermoformed & injection-molded solutions engineered for thermal resilience, leak protection, and international transport compliance.
Guangdong Santai Plastic Industry Co., Ltd. officially embarked on its entrepreneurial journey in 2010 and has been deeply involved in the plastic product manufacturing sector for over a decade. Starting as a specialized production enterprise, it has evolved into an internationally recognized beverage and food-grade packaging solution provider.
Located strategically at No.5, Xinjiang Village Industrial Zone, Changning Town, Boluo County, Huizhou City, Guangdong Province, our mega-manufacturing facility spans across 26,500 square meters of structured industrial space. Engineered with cleanrooms operating under constant temperature, humidity, and high-efficiency particulate air (HEPA) purification systems, our plant guarantees hygiene compliance from raw polymer extrusion to final boxed dispatch.

Understanding the structural integrity, melt flow index (MFI), and barrier physics of B2B shipping containers, PP blister cups, and PET clear packaging.
Polypropylene (PP) serves as the backbone material for microwave-safe, high-temperature food packaging and durable delivery vessels. Engineered via high-precision thermoforming and injection processes, modern PP packaging formulations exhibit exceptional Heat Deflection Temperatures (HDT) ranging from -20°C up to +120°C.
The crystalline structure of homopolymer and random copolymer PP variants provides structural rigidity against hot-fill applications (such as soups, single-origin coffee, and oil-heavy cuisine). During long-distance logistics, PP shipping boxes and bowl lids maintain dimensional stability, resisting stress whitening, micro-fracturing, and vacuum-collapse induced by thermal fluctuations.
For cold-chain beverage distribution and high-clarity retail display, Polyethylene Terephthalate (PET) offers superior tensile strength, optical transparency (>90% light transmission), and gas barrier properties against carbon dioxide and oxygen ingress.
Our PET cold drink cups (ranging from 12oz to 24oz sizes with customized 98mm rim geometries) undergo automated side-wall thickness profiling. This ensures consistent column strength when stacked inside heavy outer shipping cartons, mitigating deformation and side-buckling during oceanic or air freight transport.
| Polymer Type | Thermal Range (°C) | Tensile Strength (MPa) | Optical Clarity | Microwave Suitability | Primary Industrial Application |
|---|---|---|---|---|---|
| PP (Polypropylene) | -20°C to +120°C | 30 - 40 | Translucent to Semi-Clear | Excellent (Microwave-Safe) | Hot food bowls, coffee lids (PP79/PP80), hot blister cups |
| PET (Polyethylene Terephthalate) | -40°C to +65°C | 55 - 75 | Ultra-High Transparency (>90%) | Unsuitable | Cold beverage cups (98mm/95mm series), deli lids, clear packaging |
| PS (Polystyrene) | -10°C to +80°C | 35 - 50 | High Transparency / Opaque | Not Recommended | Specialized cup lids, rigid snap-on caps |
| PLA (Polylactic Acid / Bio-Polymer) | -20°C to +45°C | 40 - 60 | High Transparency | Unsuitable | Eco-friendly biodegradable straws, compostable cold cups |
Looking back at Santai Plastic's corporate history, its growth trajectory is marked by relentless perseverance. In the early days, the company barely started with just two basic production machines. Facing multiple challenges like limited equipment, insufficient production capacity, and low market recognition, the team remained committed to quality standards, gradually accumulating experience through simple processing of single product categories.
As market demand expanded and technical capabilities improved, the company continuously increased equipment investment and technological upgrades. Today, Santai operates 30 advanced thermoforming production lines and 20 extrusion production lines alongside 200+ precision injection molding units.
Production efficiency and product precision have improved simultaneously, successfully transitioning from "small-scale workshop production" to "modern large-scale manufacturing." The comprehensive catalog covers PET cold drink cups, PET cup lids, PP cups, PP cup lids, PS cup lids, injection-molded cups, injection lids, PLA straws, PP straws, and paper straws.
How direct OEM/ODM factory integration delivers total cost of ownership (TCO) optimization for multi-national beverage chains, distributors, and logistics hubs.
By procuring food-grade virgin PP, PET, and bio-PLA resins directly from tier-1 global petrochemical suppliers in multi-thousand-ton batches, Santai eliminates intermediary price volatility. This upstream scale is passed directly to wholesale buyers, securing competitive unit pricing even during global raw material fluctuations.
Backed by 300+ dedicated R&D engineers and tooling technicians, our facility designs, mills, and maintains custom CNC thermoforming molds with tolerances within ±0.05mm. This guarantees leak-proof lid fitment and zero lid-stacking jamming on automated QSR filling lines.
Shipping boxes and nested cups are engineered for maximum volumetric efficiency. By optimizing sleeve compression and carton dimensions, we maximize high-cube (40HQ) ocean container fill rates by up to 18%, significantly lowering per-unit transport tariffs.
As a growing enterprise, Santai Plastics has consistently integrated social responsibility into its development strategy, with sustained efforts in environmental protection. The company actively develops and promotes eco-friendly products, including PLA and paper straws, while progressively adopting recyclable PET and biodegradable PP materials for cup production to reduce traditional plastics' environmental impact.
Additionally, it drives green production upgrades by installing roof-mounted solar power systems to supply clean energy for workshops and offices, significantly cutting annual carbon emissions. The company also optimizes wastewater and exhaust gas treatment processes to achieve closed-loop resource recycling, setting an industry benchmark for sustainable manufacturing.
Operating standardized cleanrooms with constant temperature and humidity control, high-efficiency air filtration, and precise optical testing systems.
"Santai's products demonstrate exceptional stability during transit, remaining perfectly intact even after long-haul multi-modal shipping. Their dimensional precision perfectly matches our automated capping machinery, significantly reducing operational downtime."
"The PLA straws fully comply with EU environmental packaging directives and have been warmly received across regional retail chains. Santai's R&D capabilities and delivery efficiency far exceed our expectations."
"From sample prototyping to mass manufacturing, Santai's team has impressed with their rapid response and professionalism. Communication remains seamless and technical problem-solving is prompt and thorough."








Ensuring product hygiene and safety from the production source, every production batch meets national and international food-contact safety frameworks (including FDA 21 CFR, EU No 10/2011, and ISO standards).
By integrating structural corrugated shipping outer boxes with high-density stacking profiles, our shipping solutions guarantee zero deformation during long-distance maritime freight, port handling, and regional warehouse dispatch.
