From PVC to LDPE: The Plastics Hidden in Everyday Life

From packaging to household goods, RIC 3 and 4 plastics are everywhere. Learn how to identify them at a glance. Dear Reader,In my previous article, we explored the first two Resin Identification Codes— RIC 1 (PET) , commonly used in beverage and food containers, and  RIC 2 (HDPE) , found in sturdy household bottles and a wide range of utility products. Both plastics are among the easiest to recycle, making them central to responsible waste management and to the broader shift towards more sustainable patterns of consumption. With this foundation in place and a clearer understanding of how these codes guide our daily choices, let us now move on to the remaining classifications in the Resin Identification System and understand what each one signifies. Code 3: PVC (Polyvinyl Chloride) Code 3 refers to products made from polyvinyl chloride, or PVC—a remarkably versatile and inexpensive plastic valued for its durability, water resistance, and excellent electrical insulation. As the world’s third most produced plastic, PVC is manufactured in both rigid and flexible forms, each designed to meet a wide array of everyday needs. Flexible PVC, produced using plasticisers, appears in raincoats, boots, shower curtains, handbags, and imitation leather upholstery. It is also used in bottles for non-food items such as shampoos and cosmetics, in clear blister packaging for medicines, and in cling film that helps preserve the freshness and quality of food. Rigid PVC, prized for its strength and longevity, is used to manufacture credit cards, debit cards, national identity cards, and various inflatable items—from pool toys and floats to air mattresses. It is also present in yoga mats, sports equipment, and numerous DIY and craft materials that require durability and ease of handling. One of the most significant industrial uses of PVC is in piping. Rigid PVC pipes have increasingly replaced metal pipes in water supply, sewage, and drainage systems due to their resistance to corrosion, leakage, and environmental wear. Unplasticised PVC (uPVC) is widely used for window and door frames, offering excellent insulation, weather resistance, and minimal maintenance requirements. Vinyl flooring—produced as tiles, sheets, or planks—is another major PVC-based product, valued in homes, offices, and hospitals for its durability, affordability, and ease of cleaning. PVC’s strong insulating properties also make it ideal for coating electrical wires and cables, while PVC membranes and siding provide long-lasting, weather-resistant coverings for roofs and exterior walls. Although PVC can be recycled, the process is considerably more complex than with many other plastics. The numerous additives used to improve its flexibility, strength, and stability often interfere with the recycling process and can reduce the quality of the recycled material, limiting its suitability for certain applications. Code 4: LDPE (Low-Density Polyethylene) Code 4 identifies products made from low-density polyethylene, or LDPE—one of the most widely used plastics thanks to its lightness, flexibility, and overall durability. LDPE is commonly found in stretchable grocery bags, shopping bags, and general-purpose garbage bags. It is also extensively used in milk pouches, bread and frozen-food packaging, cling film, snack and toiletry pouches, and other everyday wrapping materials. Many squeeze bottles for glue, paints, condiments, and household liquids are made from LDPE, as are numerous lids and caps. Additionally, LDPE forms the waterproof inner lining of juice and milk cartons, helping protect the contents and extend shelf life. Beyond packaging, LDPE serves as a protective coating in various products, appears in trash-can liners, and is widely used in children’s toys such as buckets and play balls due to its resilience and safety profile. Some household goods—including certain cutting boards—are also manufactured from LDPE, benefiting from its strength and ease of cleaning. Despite its versatility and widespread use, LDPE poses notable challenges for recycling. Rigid LDPE products are somewhat easier to process, but thin bags, wraps, and cling films are difficult to collect, separate, and recycle efficiently. As a result, a significant proportion of these items unfortunately ends up in landfill. Our discussion will continue in next week’s instalment, where we will explore the remaining Resin Identification Codes in greater depth and understand how they influence recycling practices. Until then, I wish you a pleasant and enjoyable weekend.   (The author is an environmentalist. Views personal.)

The Eagle, the Dragon, the Tiger in a new ‘Cold War’ in Asia

Updated: Feb 18

As the U.S. and China lock horns, India must play its cards right without becoming a pawn in the superpower rivalry.

superpower rivalry.

Benjamin Franklin famously quipped that nothing is certain except death and taxes. In geopolitics, uncertainty is the only constant. With Donald Trump returning to the White House, the United States’ foreign policy is once again taking an unpredictable turn. The newly appointed Secretary of State, Marco Rubio, a noted China hawk, wasted no time in setting a confrontational tone with China. In his first exchange with China’s Foreign Minister, Wang Yi, Rubio reaffirmed America’s commitment to its allies, condemned China’s coercive policies, and promised to put ‘America First.’ China, in turn, issued a stern response, warning Washington to tread carefully. The stage is well-set for a renewed US-China rivalry, one that is likely to have have far-reaching consequences for India.


Under Xi Jinping, China has pursued an aggressive foreign policy, asserting territorial claims in the South China Sea, increasing pressure on Taiwan and clashing with India along the Himalayan border. The Trump administration’s first term had seen significant escalation in tensions between Washington and Beijing, including a trade war, sanctions and diplomatic spats which is only set to intensify in the second term.


Rubio’s record offers clues to what lies ahead. A staunch believer in American exceptionalism, he has been vocal about holding China accountable for its economic and military maneuvers. During Trump’s first term, he played a key role in sanctioning Chinese officials over human rights abuses and supported stronger ties with Taiwan. Now, as Secretary of State, he has made it clear that the US will double down on its commitment to counter China’s influence.


China’s response, led by Wang Yi, has been measured but firm. Unlike his predecessor, Qin Gang, who embodied Beijing’s aggressive ‘wolf warrior’ diplomacy, Wang is a seasoned diplomat known for his pragmatic approach. He has emphasized the need for both nations to manage their differences while preserving areas of cooperation. However, China’s long-term ambitions is to supplant the US as the dominant global power and consolidate its influence in Asia.


Amidst this great power rivalry, India finds itself in a precarious position. It has its own fraught history with China, particularly after the 2020 Galwan Valley clashes, which brought relations between the two Asian giants to their lowest point in decades. At the same time, India has deepened its strategic partnership with the US, joining forums like the Quadrilateral Security Dialogue (QUAD) alongside Japan and Australia. However, the India-US relationship is more fragile than it appears.


Despite converging interests in countering China, India and the US have significant differences. Trade disputes, disagreements over Russia, and Washington’s inconsistent approach towards New Delhi have caused friction. Trump’s transactional style of diplomacy could further complicate matters. While his administration has touted India as a key partner in the Indo-Pacific, his ‘America First’ doctrine could make India wary of fully aligning itself with Washington.


On the other hand, China views India as a rising competitor in Asia. Beijing has been unsettled by India’s growing economic and military clout, its firm stance on territorial disputes, and its opposition to the China-Pakistan Economic Corridor (CPEC). At the same time, China’s close ties with Pakistan and its attempts to encircle India through strategic investments in South Asia have heightened New Delhi’s security concerns.


For India, the challenge is to maintain strategic autonomy without becoming a pawn in the US-China rivalry. New Delhi cannot afford to take sides, as doing so would jeopardize its long-term interests. Instead, it must adopt a nuanced approach that balances engagement with both powers while safeguarding its own strategic imperatives.


Firstly, India must leverage multilateral platforms like the QUAD, the Shanghai Cooperation Organisation (SCO), and BRICS to strengthen its geopolitical position. While the QUAD provides a counterweight to China’s assertiveness, forums like the SCO allow India to engage Beijing diplomatically. This dual approach enables India to keep its options open and avoid over-dependence on any one power.


Secondly, India must continue to build its military and economic capabilities. A strong defence posture, coupled with robust economic growth, will enhance its bargaining power on the global stage. Investments in infrastructure, technology and manufacturing will reduce its reliance on both China and the US, allowing it to chart an independent course.


Lastly, India must refine its diplomatic strategy. It should actively engage with both Washington and Beijing, ensuring that its interests are not sidelined in the larger geopolitical contest. Prime Minister Modi’s government has demonstrated adeptness in balancing relationships with conflicting powers, whether through deepening ties with Russia while maintaining strong relations with the West or managing tensions with China while keeping diplomatic channels open. This approach will be crucial in navigating turbulent waters.


The US-China power struggle is unlikely to abate anytime soon, and India will continue to feel its ripple effects. As Washington and Beijing engage in a high-stakes contest for dominance, New Delhi must resist the temptation to lean too heavily towards either side. Instead, it should focus on strengthening its own position, ensuring that it remains a key player rather than a bystander in global affairs.


In a world of shifting alliances and unpredictable leaders, India’s best bet is to remain flexible, pragmatic and self-reliant. This means playing its cards wisely in an increasingly volatile geopolitical game.
