Compostable Square Juice Bottles
Pure Compostables manufactures square juice bottles for cold-pressed juice, smoothie, kombucha, and ready-to-drink beverage brands. Material formulations are built around plant-based PLA. Stocked sizes include 16 oz, 32 oz, 64 oz, 8 oz, 10 oz, and 12 oz.
What sets our square juice bottles apart
- In-house pelletizing. We compound and pelletize the PLA bioplastic on-site, so material consistency from batch to batch tracks back to the same line — not a third-party reseller.
- Industry-standard neck finishes. 38 mm and 43 mm continuous-thread necks work with flat caps, sport caps, and tamper-evident closures already on most bottling lines.
- End-to-end compostability. Bottle and cap are both PLA-based — no mixed-material disposal headache for the consumer or your sustainability report.
- Cold-fill stability. Bottles hold structural integrity under standard juice/kombucha cold-fill conditions (up to ~40°C); no slumping, no warp.

Who buys our square juice bottles
Cold-pressed juice brands
Direct-to-consumer juice startups and retail SKUs. Need single-batch dated bottles, custom Pantone-matched labels, and pallet-load logistics. Printed orders typically run from 5,000 units; case-volume ships for retail launches.
Kombucha producers
Small-batch breweries scaling to retail. Bottles handle moderate carbonation pressures, with optional swing-top compatibility for premium-positioned SKUs.
Smoothie & wellness brands
Meal-replacement, post-workout, and functional-beverage brands. Shelf-presence matters — high-clarity PLA pairs cleanly with see-through brand artwork or shrink sleeves.
Beverage distributors & co-packers
B2B buyers reselling to multiple beverage producers. Fulfilled by case, pallet, or container; line-ready standard sizing.
Certifications and compliance
Compostability claims are backed by certification from BPI, TUV Austria, DIN CERTCO, and (where applicable) ABA for Australia and New Zealand. We test against ASTM D6400 — 90% biodegradation in 180 days, full disintegration in 84 days, ecotoxicity, and heavy-metal limits — before any SKU ships. Our team holds the certificates internally and can supply documentation on request.

OEM, private label, and bulk orders
Our OEM and ODM workflow runs in parallel to stock SKU sales. You send vector artwork (PDF/AI) at print resolution; we return a digital proof for sign-off. For flexo runs, a physical match-print proof goes out before plates are committed. Lead time is typically 4–6 weeks from final artwork approval through production. We document spec sheets, certificates of analysis, and chain-of-custody for compliance.
Frequently asked questions about square juice bottles
What cap thread sizes are compatible?
Standard 38 mm and 43 mm continuous-thread (CT) finishes work with flat caps, sport caps, and tamper-evident closures. Custom necks (28 mm, 53 mm, swing-top) are available on OEM runs.
Can I use these bottles for hot-fill?
No — PLA softens above ~40°C, so cold-fill (or warm-fill below 40°C) only. For hot-fill applications, contact us about heat-resistant PLA blends and PHA alternatives.
What’s the minimum order quantity?
Stock SKUs ship by the case (typically 100–200 bottles per case). Printed and OEM runs start at 5,000 units; full pallets at 10,000+ units.
Will these compost in a home compost pile?
No — industrial composting only. PLA needs sustained 55–60°C and active microbial activity, conditions home compost piles don’t reach. They are BPI / EN 13432 / ASTM D6400 certified for industrial facilities.
How long is the shelf life?
Sealed empty bottles: 12–18 months in cool, dry storage. Once filled, the contents drive expiry — PLA’s oxygen and moisture barrier compares favorably with conventional PET for most cold-fill beverages.
Do you offer custom labels and print?
Yes — full-color flexo and digital printing, Pantone color-matched. MOQ ~5,000 units, lead time 4–6 weeks after artwork approval. Shrink sleeves supported.
What’s the typical lead time?
Stock SKUs: 1–2 weeks. OEM/printed runs: 4–6 weeks after artwork approval. Full container shipments: 6–8 weeks production plus ocean freight.
