PET Resin WK-881 vs. WK-851: Which Is Best for Carbonated Beverage Bottle Production?
The global carbonated beverage market is growing steadily, increasing demand for packaging materials that combine strength, safety, and efficiency. Polyethylene terephthalate (PET) resin is the leading choice for carbonated beverage bottles due to its lightweight, recyclability, and excellent barrier properties. Choosing between specialized resins like WK-881 and WK-851 is key to optimizing production and product quality.
Why PET Remains the Most Practical Sustainable Packaging Choice in South Africa
While biodegradable bottles are often promoted as environmentally superior, real-world conditions in South Africa paint a different picture. In practice, recyclable PET (polyethylene terephthalate) continues to offer the most sustainable and scalable solution for the bottled water industry. Its recyclability, established recovery network, and economic viability position PET as a cornerstone of the local circular economy.
What are the key trends behind the rapid growth of PET bottles?
Polyethylene Terephthalate (PET) bottles represent one out of every two rigid plastic packages sold worldwide, primarily used for soft drinks. As global consumption patterns evolve and regulatory pressures intensify, PET bottles are projected to account for 60% of the growth in rigid plastic packaging between 2024 and 2028. What is driving this momentum? Below are six critical trends reshaping PET bottle demand in the coming years.
BoPET Film Market Growth: Why PET Resin Choice Matters
According to forecasts, the global polyester film market is expected to surpass USD 12 billion by 2028, with a compound annual growth rate (CAGR) of 6.5%. BoPET(biaxially oriented polyethylene terephthalate film) , known for its outstanding properties, accounts for over 60% of this market share. To meet booming market demand, choosing PET(Polyethylene Terephthalate) resins precisely matched to application needs is essential.
From PC to BPA-Free PET: WK-901 Enables Safer Large-Capacity Water Bottles
Concerns over BPA contamination have increasingly put polycarbonate (PC) water bottles, especially for large-capacity use, under scrutiny. A 2024 UAE study revealed that BPA migration rises significantly with heat exposure and prolonged storage, raising serious health and regulatory concerns. In response, the EU enacted regulation (EU 2024/3190), banning BPA in food contact materials and accelerating the shift toward safer alternatives.
Scientific Debate Intensifies: Biodegradable vs. Recyclable Plastics in Tackling Global Pollution
New research urges a shift from material-centric thinking to lifecycle-based strategies tailored to specific application scenarios.
Recyclable Plastic Trays Proven More Environmentally Friendly Than Laminated Paperboard Packaging
A recent study conducted by postgraduate students from the North East Masters of Science and Engineering program has found that fully recyclable plastic trays, particularly those made with 85% recycled polyethylene terephthalate (rPET), are a more sustainable food packaging solution than laminated paperboard trays.
Do All Plastics Melt Again? — A Closer Look at Thermoplastic and Thermosetting Polymers and Their Recycling
With the growing use of plastic products worldwide, effective recycling has become crucial for environmental sustainability. The recyclability of plastics fundamentally depends on their molecular structure, particularly the distinction between thermoplastic polymers like polyethylene terephthalate (PET) and thermosetting resins.
Lagos State Government Clarifies Scope of Single-Use Plastics Ban — PET Bottles Formally Exempted
Lagos, Nigeria — May 29, 2025 The Lagos State Government, through the Ministry of the Environment and Water Resources, has issued an official clarification regarding the forthcoming prohibition of single-use plastics (SUPs), scheduled to take effect on July 1, 2025. In accordance with the state's environmental protection framework and following stakeholder consultations, PET (polyethylene terephthalate) bottles will be exempt from the enforcement of this ban.
Wankai Sole Recipient of Zero Duty in Mexico's PET Resin Anti-Dumping Decision
May 29, 2025 - Mexico issues final ruling on anti-dumping investigation against Chinese polyethylene terephthalate (PET) resin, granting Wankai New Materials Co., Ltd. a historic 0% tariff rate. This marks a historic milestone - the first time a Chinese company obtained 0% duty in Mexico's anti-dumping investigationon!
Enhancing Packaging Transparency: Why PET Resin Is the Smart Choice
In the modern consumer goods industry, packaging is no longer just a container—it's a visual gateway to product appeal. According to Mintel (2022), transparent packaging can increase product attractiveness by over 30%, especially in high-frequency impulse-buying scenarios like beverages, personal care, and ready-to-eat items.
Why "Pure" PET Resin Is Considered the Safe Choice for Food Packaging
You're about to enjoy a bottle of water or a chilled soft drink. The last thing on your mind is likely the material that kept it fresh and safe. But packaging plays a crucial role in ensuring that what’s inside remains pure. In a world where purity is key, pure polyethylene terephthalate (PET) resin stands out as the unsung hero. So, what makes pure PET the gold standard for food packaging? Let's explore why it's the trusted choice for safety, sustainability, and performance
