Compostable Bin Liners

Details

Bin liners certified to IS 17088, the Indian Standard for compostable plastics, with the CPCB certificate number printed on the carton. That number is the only thing separating a genuinely compostable bag from the many bags in this market that print a leaf on ordinary polyethylene. Having said which, the certification means something narrower than the word compostable suggests, and this is the sentence the category exists on. IS 17088 and its international twin ISO 17088 are INDUSTRIAL composting standards. The test runs at 58 C plus or minus 2, which is the temperature of a managed windrow or an in-vessel composter, and the pass mark is 90 percent disintegration within 84 days at that temperature. A home compost pit in an Indian courtyard runs at 25 to 40 C, and at 30 C this bag will take six to twelve months and may still leave visible fragments. The home-composting schemes are different certifications entirely and we hold none of them. So: this makes sense if your wet waste actually reaches a society composter, a municipal wet-waste stream that genuinely composts, or a hot pit you turn. If your wet waste goes into a mixed truck to a landfill, it will not compost meaningfully there, because nothing composts without oxygen, and this bag buys you nothing except a clean conscience. We would rather sell fewer bags than sell that.

• Material Named in Full: PBAT 55.00 percent, PLA 20.00 percent, thermoplastic maize starch 23.00 percent, bio-compatibilizers and vegetable slip 2.00 percent. Exactly 100.00% declared.
• The PBAT Truth: PBAT (polybutylene adipate terephthalate) is a petroleum-derived polymer. It is the largest single component of this bag and of nearly every bag sold as maize-starch based. A listing that leads with '100% cornstarch' is telling you the flattering third of the recipe; we declare PBAT and its origin in full.
• No Polyethylene & No Oxo-Degradables: Zero polyethylene (PE), zero polypropylene, and zero oxo-degradable additives. Oxo-degradable is ordinary plastic loaded with transition-metal salts that fragment into microplastics; it is banned in India under Plastic Waste Management Rules 2016 and rejected by CPCB.
• Octagonal Star-Sealed Bottom: The layflat tubular film is folded into 8 plies before impulse thermal sealing. An octagonal star seal concentrates load stress inward, delivering 8x higher burst resistance than conventional flat seals and carrying 5.0 kg of wet food waste without seam tears.
• 100% Unpigmented & Unprinted Film: Natural translucent matte off-white film. Zero green phthalocyanine dye masterbatch, zero synthetic inks printed on the film to leach into compost soil. All statutory text, CPCB registration numbers, and QR codes are printed strictly on the outer kraft carton.
• Honest Composting Kinetics: Disintegrates 90% within 84 days at 58°C in industrial compost. Takes 6 to 12 months in ambient home compost pits (25°C–35°C). In an anaerobic landfill, it will not break down meaningfully.
• 12-Month Dry Shelf Life: Shelf life is 12 months when stored in a cool, dry area away from direct sunlight. A biopolymer film engineered to hydrolyse will begin softening if exposed to heat and moisture.
• 100% Plastic-Free Packaging: 30 bags (Small/Medium) or 15 bags (Large) wound on a coreless perforated roll with water-soluble paper tape, packed inside a 350 GSM FSC unbleached virgin kraft paperboard dispenser box with a top tear-away perforated oval. Zero plastic shrink wrap.
