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 Perils of Protectionism: Trump’s Tariff Tantrums and India’s Dilemma

Not content with provoking China and North America, The U.S. President now targets the EU, India, and others with ‘reciprocal’ tariffs, triggering fears of a global trade war.

India’s Dilemma

Donald Trump has never been one for economic orthodoxy. His latest foray` into protectionism is a textbook example of why tariffs are a crude and self-defeating instrument. His trade policy appears to be dictated more by bravado than by economic logic. Mark McKinnon, the political strategist, once observed that trade tariffs are a slippery slope - one begets another, and soon a full-scale trade war erupts. History is littered with proof: no one wins, and consumers always suffer. Yet Trump seems determined to test this adage for himself once again.


The president’s protectionist instincts, first honed during his initial tenure, are now in overdrive. His latest barrage of tariffs on America’s trading partners threatens to unravel the fragile global economic order, with India among those caught in the crossfire.


Economists have long argued that free trade expands economic output and raises incomes, whereas tariffs restrict growth, inflate prices, and ultimately erode prosperity. Historical evidence is unambiguous: tariffs reduce employment, lower household incomes, and diminish economic output. Yet Trump’s administration is charging ahead with a 25 percent tariff on imports from Canada and Mexico - America’s largest trade partners - a move that economists estimate will shave off 0.2 percent of the country’s long-run GDP, significantly reduce full-time jobs, and impose an average tax burden of $1,072 per household. These figures do not even account for the inevitable retaliation from spurned trade partners.


If history is any guide, those retaliations will be swift and painful. The last time Trump wielded tariffs as a political cudgel, his administration imposed duties on $380 billion worth of imports, triggering one of the largest tax hikes in decades. Faced with immediate backlash from Canada and Mexico, he was forced into embarrassing reversals (twice in as many days) exempting a wide swathe of goods from the new tariffs. His abrupt policy flip-flops have only heightened global uncertainty, leaving businesses and financial markets jittery.


China, the perennial adversary in Trump’s economic battles, has responded with force. The latest wave of American tariffs has prompted Beijing to impose counter-tariffs on U.S. coal, liquefied natural gas, crude oil, agricultural machinery, and automobiles. In a more strategic escalation, China has launched an antitrust probe into Google, placed American fashion and biotech firms on its “unreliable entities” list, and curbed the export of critical minerals essential for high-tech industries. The trade skirmish is rapidly morphing into a full-fledged economic war, with consequences extending far beyond bilateral relations.


Not content with aggravating China and North America, Trump has turned his sights on the European Union, India and other key trading partners. He has announced ‘reciprocal’ tariffs on a range of imports, triggering fears of a cascading global trade conflict. His strongman tactics are a geopolitical hazard, with the potential to derail global growth.


Trump’s rhetoric on ‘reciprocal tariffs’ suggests that New Delhi’s exports, spanning gems and jewellery, pharmaceuticals and automobiles, face an uncertain future. Indian businesses are bracing for higher costs, job losses, and a potential economic slowdown, while policymakers scramble to formulate a counterstrategy.


To mitigate the fallout, New Delhi has taken some pre-emptive steps. Tariffs on high-end motorcycles have been slashed from 50 percent to 30 percent, and duties on Bourbon whiskey have been cut from 150 percent to 100 percent. Further reductions are being considered on select agricultural products, chemicals, pharmaceuticals, medical devices, and electronic goods. India is also contemplating increased imports of American energy products and defence equipment, with the F-35 fighter jet potentially on the shopping list. Yet these stopgap measures are hardly a sustainable solution.


Recognizing the gravity of the situation, External Affairs Minister S. Jaishankar recently suggested that India and the U.S. are working towards a separate bilateral trade agreement. While some hawks advocate retaliatory tariffs, India must take a pragmatic approach. A full-fledged trade war would be mutually destructive, and diplomacy remains the best course. Commerce Minister Piyush Goyal has been dispatched to Washington for negotiations, but whether his efforts will bear fruit remains to be seen.


Beyond direct U.S.-India trade relations, there are additional risks. As Trump tightens the screws on China, India may find itself inundated with an influx of cheaper Chinese goods seeking alternative markets. The prospect of intensified competition with China in third-country markets further complicates New Delhi’s economic calculus.


For India, the path forward is clear but challenging. It must shield itself from the worst effects of Trump’s economic nationalism while securing long-term access to key markets. The trade war’s unpredictability demands agility, strategic diversification, and deeper engagement with like-minded trading partners. As former U.S. Congressman Todd Rokita once said, “Talk is cheap. Actions are what matter.” New Delhi must ensure that its response to Trump’s tariffs is measured, proactive and above all, effective.
