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.)

A Legacy of Rupture: Trudeau and the Undoing of Indo-Canadian Relations

Updated: Jan 10

Trudeau’s divisive tenure serves as a cautionary tale of how domestic political calculations can erode international partnerships.

Justin Trudeau

Justin Trudeau’s resignation as head of Canada’s Liberal Party earlier this week perfectly encapsulated the title of one of Gabriel Garcia Marquez’s best-known novels, Chronicle of a Death Foretold. For Trudeau’s years of political missteps, ideological gambits and diplomatic faux pas indeed were sad chronicles that foretold his political death.


Once heralded as a progressive beacon on the global stage, Trudeau leaves behind a Canada with strained international alliances, most notably with India—a relationship painstakingly built over decades and left in shambles under his leadership.


For years, India and Canada enjoyed a robust partnership rooted in shared democratic values, pluralism, and deepening trade ties. Canada became a preferred destination for Indian professionals and students, fostering invaluable people-to-people connections. Under Trudeau, however, this relationship deteriorated rapidly, eroding trust on both sides and plunging bilateral ties into their lowest ebb.


Trudeau’s tenure saw the Indo-Canadian relationship collapse under the weight of a series of unseemly controversies. His undiplomatic behaviour during a state visit to India in 2018 raised eyebrows, but it was his handling of the Sikh separatist issue that ignited a full-blown crisis. By failing to take decisive action against Khalistani elements in Canada, Trudeau emboldened extremists who openly campaigned against India’s territorial integrity, triggering outrage in New Delhi.


The final blow came last year when Trudeau accused India of being involved in the killing of Hardeep Singh Nijjar, a designated Khalistani terrorist. These allegations were made without providing substantive evidence, and many suspected that the claims were a calculated diversion from Trudeau’s mounting domestic woes, including allegations of Chinese interference in Canadian politics.


Adding insult to injury, Trudeau expelled Indian diplomats and accused Indian agents of criminal activities on Canadian soil, escalating the crisis into a full-scale diplomatic row. Canadian authorities failed to curtail extremist violence targeting Indian diplomats and citizens, further alienating India.

Trudeau’s combative approach extended to accusations against Indian Home Minister Amit Shah, alleging intimidation campaigns in Canada—a claim New Delhi dismissed as baseless. His government also imposed restrictive visa protocols on Indian citizens, straining economic and cultural exchanges.


Domestic Debacles

While Trudeau’s anti-India rhetoric dominated headlines, his domestic challenges proved equally disastrous. Rising housing prices, an immigration crisis and spiralling inflation eroded his approval ratings. Scandals such as the blackface controversy and challenges in his personal life further tarnished his image.


The economic uncertainty triggered by then-President Trump’s threats of imposing tariffs on Canadian goods added to Trudeau’s mounting pressures. By the start of the new year, calls for his resignation were deafening, amplified by Deputy Prime Minister Chrystia Freeland’s abrupt exit from the cabinet.


Trudeau’s resignation offers a chance for reset, but the path forward is fraught with uncertainty. His successor will inherit a Canada-India relationship fraught with distrust, alongside the daunting task of repairing diplomatic, economic, and security ties. Several contenders have emerged for Trudeau’s mantle, each with distinct implications for India.


Chrystia Freeland, Trudeau’s former deputy and finance minister, boasts a distinguished career and is widely seen as a rational actor. Her leadership could offer a measured approach to rebuilding trust with India. In contrast, Dominic LeBlanc, Trudeau’s close ally and current finance minister, might be less inclined to depart from his predecessor’s policies, raising concerns in New Delhi.


Mélanie Joly, Canada’s foreign affairs minister, has shown pragmatism in her diplomatic engagements. Her leadership could bring a more balanced approach, especially if she distances herself from Trudeau’s combative style. Mark Carney, a former central banker with international credentials, has been quietly lobbying for support. His technocratic background suggests a reconciliatory approach, though his ties to Trudeau’s team could complicate perceptions in India.


A dark horse in the race and the current transport minister, Anita Anand brings a unique perspective with her Indian heritage. While her selection could signal a new chapter in Indo-Canadian ties, New Delhi would be wise to temper expectations, given past experiences with leaders of Indian origin in Western democracies.


Canada’s next leader will not only have to navigate relations with India but also manage the country’s ties with the United States led by Trump. Washington’s posture toward Ottawa will inevitably influence Canada’s foreign policy, including its approach to New Delhi.


For India, extending a hand of friendship to Canada’s new leader is essential, but it takes two to tango. A constructive relationship will require concessions and commitments from both sides.


Trudeau’s tenure will be remembered as a cautionary tale of how domestic political calculations can undermine international partnerships. His focus on identity politics, combined with his failure to address the complexities of Canada’s multiculturalism, alienated one of the country’s most important global partners.


Yet his resignation provides a glimmer of hope. Canada-India ties have weathered storms before and can do so again. Much depends on whether Trudeau’s successor can rebuild bridges while addressing the domestic fractures that Trudeau left behind. Trudeau’s departure marks the end of an era—an era marked not by the promise of progress, but by the perils of hubris.
