Cost-Efficiency: The Competitive Edge of TPS
For most manufacturers, the barrier to “going green” is the premium price tag. Thermoplastic Starch (TPS) shatters this barrier by offering the most competitive price point in the bioplastics market. When you choose TPS, you aren’t just buying a resin; you are optimizing your entire cost of ownership.
Competitive Raw Material Pricing
Unlike petroleum-based resins (PP/PE) that fluctuate with oil prices, or premium biopolymers like PLA and PHA, TPS relies on abundant agricultural feedstocks.
- The “Cost Leader” among Bioplastics: TPS is consistently 30–50% more affordable than PLA, making it the only viable option for high-volume single-use items.
- Advantage: Our strategic sourcing of local tapioca starch eliminates import duties and minimizes logistics costs, providing you with a stable, year-round pricing structure.
| Material Type | Price Index (PP = 100) | Regulatory Impact | Supply Stability |
| TPS (Neat/Blends) | 85 – 115 | Exempt from Plastic Taxes | High (Local Sourcing) |
| Conventional PP | 100 | High (Increasing Taxes) | Moderate (Oil Dependent) |
| PLA | 170 – 200 | Exempt | Moderate |
| PHA | 300+ | Exempt | Low (Limited Capacity) |
Zero-CAPEX Integration
You don’t need a new factory to transition to TPS. Our grades are designed for Zero-CAPEX (Capital Expenditure) integration.
- Equipment Compatibility: Runs on your existing injection molding and extrusion lines with minor parameter optimization.
- Energy Savings: Processing at 20–30°C lower than PP significantly reduces your monthly utility bills and shortens cooling cycles, increasing your units-per-hour output.
The "Hidden" ROI: Compliance & Waste Reduction
Total Cost of Ownership (TCO) extends beyond the price per kilogram.
- Tax Avoidance: Avoid the “Plastic Taxes” and Carbon Border Adjustment Mechanisms (CBAM) that are now hitting petroleum-based exports.
- Waste Management: Off-spec production and scrap are 100% compostable, reducing industrial waste disposal fees and supporting a zero-waste manufacturing site.

Overcoming Challenges: The "Water & Strength" Problem
A transparent supplier is a reliable partner. At SALESPLASTICS, we acknowledge that native starch is naturally hydrophilic. However, through advanced molecular engineering and strategic blending, we have transformed this “weakness” into a controllable performance variable.
Understanding the Moisture Factor
Starch molecules interact with environmental humidity, which can affect mechanical stiffness.
- The Stability Window: Our engineered TPS maintains 90%+ of its structural integrity at relative humidity (RH) levels below 70%—ideal for the majority of global retail and ambient storage environments.
- Predictable Performance: We provide detailed stress-strain data across various humidity profiles, ensuring your packaging design accounts for real-world distribution.
Our Triple-Shield Strategy for Durability
We don’t just sell raw starch; we provide fortified formulations that utilize three primary stabilization technologies:
- A. Chemical Modification (Acetylation & Cross-linking): We modify the starch hydroxyl groups to reduce water affinity, ensuring the material remains crisp and strong even in tropical climates.
- B. High-Performance Blending (TPS + PLA/PBAT): By alloying TPS with hydrophobic biopolyesters, we create a “sea-island” morphology. The PLA/PBAT acts as a protective shield, blocking moisture while the TPS provides cost-efficiency.
- C. Nano-Reinforcement: For high-end applications, we incorporate bio-based nano-fillers that create a “tortuous path” for gas and water molecules, drastically improving the oxygen barrier.
| Solution Level | Technology Applied | Ideal Application |
| Standard | Plasticized TPS | Dry food bags, short-term wraps |
| Advanced | TPS-PLA Alloy | Cutlery, rigid trays, coffee pods |
| Premium | Coated / Nano-filled | Long-shelf-life snacks, refrigerated dairy |
Struggling with moisture sensitivity in your current bio-based application?
Don’t let environmental factors limit your sustainable transition. Our technical team can help you select the precise TPS-PLA blend ratio or nano-reinforced formulation tailored to your specific storage conditions.
Sustainable Production and Circular Economy Integration
True sustainability in the food packaging sector is defined by more than just eco-labels—it is measured by supply chain resilience and production cost-efficiency. Our TPS resin is engineered to provide a stable, high-performance alternative to volatile petroleum-based plastics.
Sustainable Feedstock
Unlike PLA or corn-based biopolymers that often face “food-vs-fuel” ethical dilemmas and price volatility, our TPS utilizes industrial-grade cassava (tapioca).
- Non-Food Competition: Our tapioca is grown on marginal lands unsuitable for intensive food crops, eliminating “food-vs-fuel” ethical concerns.
- Low Water Footprint: Cassava is naturally drought-tolerant, requiring significantly less irrigation than corn (for PLA) or sugarcane.
- Zero Deforestation: Sourced from long-established agricultural zones, our feedstock involves no clearing of natural ecosystems or rainforests.
Carbon Footprint: A Decisive Climate Advantage
TPS acts as a carbon sink. Through photosynthesis, the source plants capture atmospheric CO₂, which is then stored within the polymer structure of your packaging.
| Material Type | Carbon Footprint (kg CO2-eq/kg) | Net Climate Impact |
| TPS (Renewable Energy) | 0.8 – 1.4 | Lowest |
| PLA (Corn-based) | 1.4 – 2.3 | Moderate |
| Conventional LDPE | 2.3 – 3.5 | High (Fossil-based) |
Energy Efficiency: Our processing temperatures are 20–40°C lower than traditional plastics, directly reducing the “Scope 2” emissions of your manufacturing facility.
