Is LDPE recyclable? Yes. Is it recycled? Sometimes.
We make plastic for a living, which makes us the wrong people to ask for reassurance and the right people to ask for facts. LDPE is resin code 4, genuinely recyclable, and not biodegradable. The gap between recyclable and recycled is a collection problem, not a chemistry one.
Talk to us honestly →
- LDPE is resin code 4. The number in the triangle. It is recyclable and reusable.
- LDPE is not biodegradable. It does not break down usefully in soil or landfill. Anyone selling "biodegradable LDPE" is selling a phrase.
- Film is harder to recycle than bottles. Not because of the polymer, but because film is light, it tangles in sorting machinery, and it usually arrives contaminated.
- Clean film is genuinely valuable. Unprinted factory offcuts and clean liners are a sought-after grade in the reprocessing trade.
- The biggest environmental lever we control is using less plastic per job, which usually means correcting an over-specced gauge. That is also the lever that saves you money.
What actually happens to LDPE film in India
The recycling chain for film has four steps, and it breaks at a different one than most people assume.
- Collection. This is where it breaks. Film is light, low value per piece, and blows around. Formal kerbside systems in most Indian cities are not built to capture it, so what gets collected mostly comes through informal waste-picker networks and factory-level segregation.
- Sorting. Clean and natural film is separated from printed and mixed. Colour and print are what determine the value of the resulting pellet, because you cannot un-print film.
- Washing and shredding. Food residue, soil and adhesive have to come off. This is why agricultural mulch film, technically recyclable, is largely uneconomic: it comes off the field full of soil and moisture.
- Pelletising. The clean flake is melted and extruded into reprocessed granules, which come back into products like site sheet, garbage bags and industrial liners. Not food packaging, ever.
The encouraging part of that chain: India's informal recycling economy is genuinely effective at recovering material that has value. The discouraging part: value is created by cleanliness and sorting, and most film reaches the end of its life dirty and mixed.
What a buyer can actually do
On EPR, and on the claims we avoid
India's Extended Producer Responsibility framework under the Plastic Waste Management Rules puts obligations on brand owners and producers to account for the plastic packaging they put into the market. If you are a brand, that obligation is yours, and your packaging supplier is a participant in your reporting rather than a substitute for it. We will give you the material facts you need for it: polymer type, whether the film is virgin or recycled, and the weight you bought.
Four claims we will not make
- "Biodegradable". LDPE is not. Oxo-degradable additives fragment film into smaller pieces, which is not the same as biodegrading, and several jurisdictions have moved against them for exactly that reason.
- "Compostable". That is a different material family entirely, and it needs industrial composting infrastructure to mean anything.
- "100 percent recycled". Any film that has to be clear, strong or food-safe cannot be, and we will tell you the real blend.
- "Eco-friendly plastic". The phrase means nothing measurable. We would rather talk about grams per shipment, which does.
We understand this is not the marketing copy you expected from a plastics manufacturer. It is more useful, and it is the only version that survives a customer asking a follow-up question.
