Polyethylene terephthalate (PET bottle-grade resin)

Description

Product Overview
Polyethylene terephthalate (PET bottle-grade resin) is a high-purity thermoplastic polyester engineered for the production of rigid food-contact packaging, primarily preforms and containers for the global beverage industry. Its key value proposition lies in exceptional mechanical strength, gas-barrier properties, and crystal clarity, enabling lightweighting without structural compromise. As the most widely recycled packaging polymer, PET is strategically critical for enterprises transitioning to circular economy models while maintaining high-speed, high-volume filling line efficiency.

Key Specifications & Technical Characteristics

• Chemical composition: Polyethylene terephthalate (C₁₀H₈O₄)ₙ, virgin bottle-grade homopolymer

• Intrinsic viscosity (I.V.): 0.74–0.84 dL/g (customizable for carbonated soft drinks, water, or edible oils)

• Physical form: Clear, amorphous pellets; natural color; bulk density approx. 0.85–0.95 g/cm³

• Acetaldehyde content: ≤ 1.0 ppm (post-molding) for superior taste preservation

• Moisture content before processing: ≤ 0.002% (0.002 percent, dry-as-delivered guaranteed)

• Packaging options: 1,000–1,200 kg super sacks, 25 kg moisture-barrier bags, or bulk pneumatic trailers

• Shelf life: 12 months when stored below 40°C / 50% relative humidity in original sealed packaging

Core Industrial Applications

• Bottled water & carbonated soft drinks: Superior I.V. retention ensures side-wall load strength and stress-crack resistance under carbonation pressure.

• Edible oils & sauces: Excellent oxygen scavenging compatibility and chemical resistance prevent rancidity and flavor migration.

• Pharmaceutical & nutraceutical containers: Low acetaldehyde levels meet USP Class VI requirements; FDA/EU food-contact compliant.

• Thermoformed trays & clamshells (amorphous PET): Higher impact strength vs. PVC or PLA, fully recyclable in existing PET stream.

Competitive Advantages

• Quality consistency: Single-source polymerization with SPC-controlled I.V. variation ≤ ±0.02 dL/g across all lots.

• Supply reliability: Dedicated production lines for bottle-grade resin; stock available from three continental hubs (Asia, Europe, Americas).

• Logistics capability: Certified moisture-barrier packaging + real-time tracking; lead times 10–14 days for 20MT+ orders.

• Price competitiveness: Direct off-take from integrated PTA/MEG feedstock chain, removing petrochemical spot volatility.

• Sustainability advantage: ISCC PLUS certified mass-balance grades with up to 50% recycled content (rPET) without I.V. degradation.

Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT (20 metric tons) per grade

• Loading capacity: 24–26 MT per standard 20-foot dry container (palletized super sacks); 22 MT per 20-foot for 25 kg bags
