For the last two decades, LLDPE stretch film has been a silent workhorse of global logistics — invisible on the pallet, indispensable in the container. In 2026, that silent workhorse is finally getting boardroom attention: ESG procurement teams at retailers, distributors and 3PLs across the UK, USA and European Union are now filtering their supplier base by packaging emissions and end-of-life waste. Biodegradable stretch film has moved from a niche experiment to a mainstream requirement.
What exactly is biodegradable stretch film?
Biodegradable stretch film is an LLDPE (Linear Low-Density Polyethylene) stretch film formulated with a proprietary additive that accelerates the film's breakdown under natural microbial and enzymatic conditions. Unlike standard LLDPE — which can take 400+ years to decompose — biodegradable stretch film breaks down significantly faster while retaining the puncture resistance, 300%+ elongation and consistent cling that pallet stability demands.
The 3 forces driving the switch
1. Regulatory pressure — especially in the EU and UK
The EU's Packaging and Packaging Waste Regulation (PPWR) has set binding targets for recyclable and biodegradable secondary packaging. The UK's Plastic Packaging Tax now charges £217.85 per tonne on plastic packaging with less than 30% recycled or biodegradable content. For a mid-sized exporter shipping 200 tonnes/year, that's over £43,000 in avoidable tax. Biodegradable variants sidestep this entirely.
2. Retailer ESG scorecards
Walmart's Project Gigaton, Tesco's Preferred Suppliers program, IKEA's IWAY standard and Amazon's Climate Pledge Friendly all now score suppliers on packaging sustainability. A single failed audit can knock a supplier out of a preferred category — and biodegradable stretch film is a straightforward, verifiable checkbox to tick.
3. Consumer-facing brand pressure
Even in B2B categories, end consumers are asking questions. Marketplace listings on Amazon, Etsy and Faire now display packaging sustainability badges. Exporters who can substantiate biodegradable outer wrap earn measurable listing preference — and that flows straight to their gross merchandise value.
Does 'biodegradable' mean weaker film?
This is the #1 objection we hear from procurement teams — and the answer is: no. Modern biodegradable LLDPE films use additive technology (not compostable bioplastics), so the base polymer is identical to standard stretch film. Cast-line manufacturing preserves the same molecular alignment. In our internal testing at the Wellpack Polyplast Patan facility, biodegradable variants have delivered comparable puncture resistance, 280–300%+ elongation and identical cling behaviour to conventional 20 μm machine-grade film.
How to specify biodegradable stretch film for export shipments
- Confirm the additive technology and any independent testing certifications (ISO 14855, ASTM D5511 or equivalent)
- Match micron to load class: 12–17 μm for light loads, 20–25 μm for standard pallets, 25–35+ μm for sharp-edged or heavy loads
- Choose machine grade for automatic wrappers and hand grade for manual pallet operations
- For sea freight, opt for higher-cling variants and pre-stretched film to maximise container yield
Why a Patan (Gujarat) cast line matters to global buyers
Wellpack Polyplast's newly commissioned 2026 stretch film cast line at our 70,000 sq ft facility in Patan, Gujarat, produces LLDPE stretch films from 8 μm to 51 μm — including biodegradable variants — with the same gauge consistency and clarity as European-manufactured film. Combined with our BOPP tape coating unit at the same site, our combined group capacity is now 1000+ tons per month, and we currently export to 18+ countries with full documentation and logistics support.
